A Comparability of Noise Discount Packages for Astrophotography
On this detailed technical article, I examine six AI-based noise discount applications for the calls for of astrophotography. Some can work wonders. Others can destroy your picture.
During the last two years, we now have seen a spate of specialised applications launched for eradicating digital noise from photographs. The brand new era of applications makes use of synthetic intelligence (AI), AKA machine studying, educated on hundreds of photographs to raised distinguish undesirable noise from fascinating picture content material.
No less than that’s the promise – and for noisy however regular daytime photographs they do work very nicely.
However in astrophotography, our foremost topics – stars – can look so much like specks of pixel-level noise. How nicely can every program scale back noise with out eliminating stars or needed particulars, or introducing odd artifacts, making photographs worse?
To search out out, I examined six of the brand new AI-based applications on real-world – or somewhat “real-sky” – astrophotos. Does one program stand out from the remaining for astrophotography?
Notice: All the photographs are full-resolution JPGs you’ll be able to faucet or click on on to obtain for detailed inspection.
TL;DR Abstract
The brand new AI-trained noise discount applications can certainly get rid of noise higher than older non-AI applications whereas leaving superb particulars untouched and even sharpening them.
Of the group examined, the winner to be used on simply star-filled photographs is a specialised program for astrophotography, NoiseXTerminator from RC-Astro.
For nightscapes and different photographs, Topaz DeNoise AI carried out nicely, higher than it did in earlier variations that left plenty of patchy artifacts, one thing AI applications may be vulnerable to.
Whereas ON1’s new NoNoise AI 2023 carried out superb, it proved barely worse in some circumstances than its earlier 2022 model. Its new sharpening routine wants work.
Different new applications, notably Topaz Picture AI and Luminar’s Noiseless AI, additionally want enchancment earlier than they’re prepared for use for the trials of astrophotography.
For causes defined beneath, I might not suggest DxO’s PureRAW2.
Methodology
As described beneath, whereas among the applications can be utilized as stand-alone purposes, I examined all of them as plug-ins for Photoshop, making use of every as a wise filter utilized to a developed uncooked file introduced into Photoshop as a Digicam Uncooked sensible object.
Most of those applications state that higher outcomes is perhaps obtainable through the use of the stand-alone app on authentic uncooked recordsdata. However for my private workflow I choose to develop the uncooked recordsdata with Adobe Digicam Uncooked, then open these into Photoshop for stacking and layering, making use of any additional noise discount or sharpening as non-destructive sensible filters.
Many astrophotographers additionally select to stack unedited authentic photographs with specialised stacking software program, then apply additional noise discount and modifying later within the workflow. So my workflow and check procedures replicate that.
Nonetheless, the exception is DxO’s PureRAW2. It might probably work solely on uncooked recordsdata as a stand-alone app, or as a plug-in from Adobe Lightroom. It doesn’t work as a Photoshop plug-in. I examined PureRAW2 by dropping uncooked Canon .CR3 recordsdata onto the app, then exporting the outcomes as uncooked DNG recordsdata, however with the identical settings utilized as with the opposite uncooked recordsdata. For the nightscape and wide-field photographs taken with lenses in DxO’s intensive database, I used PureRAW’s lens corrections, not Adobe’s.
As proven above, I selected three consultant photographs:
A nightscape with star trails and an in depth foreground, at ISO 1600.
A large-field deep-sky picture at ISO 1600 with an 85mm lens, with very tiny stars.
An in depth-up deep-sky picture taken with a telescope and at a excessive ISO of 3200, exhibiting thermal noise scorching pixels.
Every is a single picture, not a stack of a number of photographs.
Earlier than making use of the noise discount, the uncooked recordsdata obtained simply primary coloration corrections and a distinction increase to emphasise noise all of the extra.
The Contenders
Within the check outcomes for the three photographs, I present the unique uncooked picture, plus a model with noise discount and sharpening utilized utilizing Adobe Digicam Uncooked’s personal sliders, with luminance noise at 40, coloration noise at 25, and sharpening at 25.
I take advantage of this as a base comparability, because it has been the noise discount I’ve lengthy utilized to pictures. Nonetheless, ACR’s routine (additionally present in Adobe Lightroom) has not modified in years. It’s good, however it isn’t AI.
The brand new sensible AI applications ought to enhance upon this. However do they?
Please word:
I’ve shunned offering costs and explaining shopping for choices, as frankly, some may be complicated!
For these particulars and for trial copies, go to the software program’s web site by clicking on the hyperlink within the header product names beneath.
All applications can be found for Home windows and macOS. I examined the latter variations.
I’ve not supplied tutorials on learn how to use the software program; I’ve simply reported on their outcomes. For troubleshooting their use, please seek the advice of the software program firm in query.
ON1’s foremost product is the Lightroom/Photoshop different program referred to as ON1 Picture RAW, which is up to date yearly to main new variations. It has full cataloging choices like Lightroom and picture layering like Photoshop. Its Edit module accommodates the NoNoise AI routine. However NoNoise AI may be bought as a stand-alone app that additionally installs as a plug-in for Lightroom and Photoshop. It’s what I examined right here. The newest 2023 model of NoNoise AI added ON1’s new Tack Sharp AI sharpening routine.
Model examined: 17.0.1
This program has confirmed very talked-about and has been adopted by many photographers – and astrophotographers – as a vital a part of an modifying workflow. It performs noise discount solely, providing a alternative of 5 AI fashions. Auto modes can select the fashions and settings for you primarily based on the picture content material, however you’ll be able to override these by adjusting the energy, sharpness, and restoration of authentic element as desired.
A separate program, Topaz Sharpen AI, is particularly for picture sharpening, however I didn’t check it right here. Topaz Gigapixel AI is for picture resizing.
Model examined: 3.7.0
In 2022 Topaz launched this new program which includes the trio of noise discount, sharpening, and picture resizing in a single package deal. Like DeNoise, Sharpen, and Gigapixel, Picture AI works as a stand-alone app or as a plug-in for Lightroom and Photoshop. Picture AI’s Autopilot routinely detects and applies what it thinks the picture wants. Whereas it’s doable to regulate settings, Picture AI presents a lot much less management than DeNoise AI and Topaz’s different single-purpose applications.
As of this writing in November 2022, Picture AI is having fun with nearly weekly updates and appears to be the place Topaz is focusing its growth and advertising and marketing efforts.
Model examined: 1.0.9
In contrast to the opposite noise discount applications examined right here, Luminar Neo from the software program firm Skylum is a full-featured picture modifying program, with an emphasis on one-click AI results. A type of is the brand new Noiseless AI, accessible as an extra-cost extension to the principle Neo program, both as a one-time buy or by annual subscription. Noiseless AI can’t be bought by itself. Nonetheless, Neo with most of its extensions does work as a plug-in for Lightroom and Photoshop.
Being new, Luminar Neo can be up to date continuously, with extra extensions coming within the subsequent few months.
Model examined: 1.5.0
Like ON1, DxO makes a full-featured different to Adobe’s Lightroom for cataloging and uncooked growth referred to as DxO PhotoLab, in model 6 as of late 2022. It accommodates DxO’s Prime and DeepPrime noise discount routines. Nonetheless, as with ON1, DxO has spun off simply the noise discount and lens correction components of PhotoLab right into a separate program, PureRAW2, which runs both as a stand-alone app or as a plug-in for Lightroom – however not Photoshop, as PureRAW works solely on authentic uncooked recordsdata.
In contrast to all the opposite applications, PureRAW2 presents basically no choices to regulate settings, simply the choice to use, or not, lens corrections, and to decide on the output format. For this testing, I utilized DeepPrime and exported out to DNG recordsdata.
Model examined: 2.2
In contrast to the opposite applications examined, NoiseXTerminator from astrophotographer Russell Croman is designed particularly for deep-sky astrophotography. It installs as a plug-in for Photoshop or Affinity Picture, however not Lightroom. It is usually accessible below the identical bought license as a “course of” for PixInsight, a complicated program fashionable with astrophotographers, as it’s designed only for modifying deep-sky photographs.
I examined the Photoshop plug-in model of Noise XTerminator. It receives occasional updates to each the precise plug-in and separate updates to the AI module.
Model examined: 1.1.2, AI mannequin 2
Nightscape Check
As with the opposite check photographs, the panels present a extremely magnified part of the picture, indicated within the inset. I shot the picture of Lake Louise in Banff, Alberta with a Canon RF15-35mm lens on a 45-megapixel Canon R5 digicam at ISO 1600.
Adobe Digicam Uncooked’s primary noise discount did job, however like all common routines it does soften the picture as a by-product of smoothing out high-ISO noise.
primary noise discount did job, however like all common routines it does soften the picture as a by-product of smoothing out high-ISO noise. ON1 NoNoise 2023 retained panorama element higher than ACR however softened the star trails, regardless of my including sharpening. It additionally produced a considerably patchy noise smoothing within the sky. This was with Luminosity backed off to 75 from the auto setting (which at all times cranks up the extent to 100 whatever the picture) and with the Tack Sharp routine set to 40 with Micro Distinction at 0. It left a uniform pixel-level mosaic impact within the shadow areas. Regardless of the brand new Tack Sharp possibility, the picture was softer than with final yr’s NoNoise 2022 model (not proven right here as it’s now not accessible) which produced higher shadow outcomes.

Topaz DeNoise AI did a greater job than NoNoise retaining the sharp floor element whereas smoothing noise, at all times extra apparent within the sky in such photographs. Even so, it additionally produced some patchiness, with some areas exhibiting extra noise than others. This was with the Customary mannequin set to 40 for Noise and Sharpness, and Get well Particulars at 75. I present the opposite mannequin variations beneath.

This was with the Customary mannequin set to 40 for Noise and Sharpness, and Get well Particulars at 75. I present the opposite mannequin variations beneath. Topaz Picture AI did a poor job, producing plenty of noisy artifacts within the sky and an over-sharpened foreground riddled with colourful speckling. It added noise. This was with the Regular setting and the default Autopilot settings.

This was with the Regular setting and the default Autopilot settings. Noiseless AI in Luminar Neo did an honest job smoothing noise whereas retaining, certainly sharpening floor element with out introducing ringing or colourful edge artifacts. The sky was left with some patchiness and uneven noise smoothing. This was with the recommended Center setting (vs Low and Excessive) and default ranges for Noise, Element, and Sharpness. Nonetheless, I do like Neo (and Skylum’s earlier Luminar AI) for including different ending results to pictures similar to Orton glows.

Nonetheless, I do like Neo (and Skylum’s earlier Luminar AI) for including different ending results to pictures similar to Orton glows. DxO PureRAW 2 did easy noise very nicely whereas enhancing sharpness quite a bit, nearly an excessive amount of, although it didn’t introduce apparent edge artifacts. Be mindful it presents no probability to regulate settings, aside from the mode – I used DeepPrime vs the traditional Prime. Its foremost downside is that in making the conversion again to a uncooked DNG picture it altered the looks of the picture, on this case darkening the picture barely. It additionally made some faint star trails look wiggly!

Its foremost downside is that in making the conversion again to a uncooked DNG picture it altered the looks of the picture, on this case darkening the picture barely. It additionally made some faint star trails look wiggly! Noise XTerminator actually smoothed out the sky and did so very uniformly with out doing a lot hurt to the star trails. Nonetheless, it smoothed out floor element unacceptably, not shocking given its specialised coaching on stars, not terrestrial content material.
Conclusion: For this picture, I’d say Topaz DeNoise AI did one of the best, although not excellent, job.
This was shocking, as assessments I did with earlier variations of DeNoise AI confirmed it leaving many patchy artifacts and coloured edges in locations. Frankly, I used to be postpone utilizing it. Nonetheless, Topaz has improved DeNoise AI so much.
Why it really works so nicely, when Topaz’s newer program Picture AI works so poorly, is difficult to know. Absolutely they use the identical AI code? Apparently not. Picture AI’s noise discount is just not the identical as DeNoise AI.
Equally, ON1’s NoNoise 2023 did a worse job than their older 2022 model. One can assume its efficiency will enhance with updates. The problem appears to be with the brand new Tack Sharp addition.
NoiseXTerminator is perhaps a good selection for decreasing noise in simply the sky of nightscape photographs. It isn’t appropriate for foregrounds.
Huge-Subject Picture Check
I shot this picture of Andromeda and Triangulum with an 85mm Rokinon RF lens on the 45-megapixel Canon R5 on a star tracker. Stars at the moment are factors, with small ones simply mistaken for noise. Let’s see how the applications deal with such a picture, zooming right into a tiny part exhibiting the galaxy Messier 33.
Adobe Digicam Uncooked’s noise and sharpening routines do care for the worst of the luminance and chrominance noise, however inevitablyleave some graininess to the picture. That is historically handled by stacking a number of sub-exposures.
ON1 NoNoise 2023 did a greater job than ACR, smoothing the worst of the noise and doing so uniformly, with out leaving uneven patchiness. Nonetheless, it did soften star photographs, nearly prefer it was making use of a 1- or 2-pixel gaussian blur, including a barely hazy look to the picture. And but the faintest stars that appeared as simply perceptible blurs within the authentic picture have been sharpened to one- or two-pixel factors. This was with solely NoNoise AI utilized, and no Tack Sharp AI. And, as I present beneath, NoNoise’s default “Excessive Element” possibility launched with the 2022 model and included within the 2023 version completely destroys star fields. Keep away from it.
Topaz DeNoise AI did a greater job than Digicam Uncooked, although it wasn’t miles forward. This was with the Customary setting. Its Low Mild and Extreme fashions weren’t nearly as good, shocking as you would possibly assume a type of decisions could be one of the best for such a picture. It pays to examine Topaz’s numerous fashions’ outcomes. Customary didn’t erase stars; it truly sharpened the fainter ones, nearly a bit of an excessive amount of, making them appear like specks of noise. Taking part in with Improve Sharpness and Get well Element didn’t make a lot distinction to this habits.
Topaz Picture AI once more carried out poorly. Its Regular mode left plenty of noise and grainy artifacts. Whereas its Sturdy mode proven right here did easy background noise higher, it softened stars, wiping out the faint ones and leaving coloured edges on the brighter ones.
Noiseless AI in Luminar Neo did easy superb noise considerably, higher than Digicam Uncooked, however nonetheless left a grainy background, although with the celebs largely untouched in measurement and coloration.
DxO PureRAW 2 did get rid of noise fairly nicely, whereas leaving even the faintest stars intact, in contrast to with the deep-sky picture beneath, which is odd. Nonetheless, it added some darkish halos to vibrant stars from over-sharpening. And, as with the nightscape instance, PureRAW’s output DNG was darker than the uncooked that went in. I don’t need noise discount applications altering the fundamental look of a picture, even when that may be corrected later within the workflow.

I don’t need noise discount applications altering the fundamental look of a picture, even when that may be corrected later within the workflow. Noise XTerminator carried out fantastically, as anticipated – in any case, that is the subject material it’s educated to work on. It smoothed out random noise higher than any of the opposite applications whereas leaving even the faintest stars untouched, in actual fact sharpening them barely. Particulars within the little galaxy have been additionally unhurt.
Conclusion: The clear winner was NoiseXTerminator.
Topaz DeNoise was a good second place, performing higher than it had accomplished on such photographs in earlier variations. Even so, it did alter the looks of faint stars which could not be fascinating.
ON1 NoNoise 2023 additionally carried out fairly nicely, with its softening of brighter stars but sharpening of fainter ones maybe acceptable, even fascinating for an impact.
Telescopic Deep-Sky Check
I shot this picture of the NGC 7822 complicated of nebulosity with a SharpStar 61mm refractor, utilizing the red-sensitive 30-megapixel Canon Ra and with a narrowband filter to isolate the crimson and inexperienced mild of the nebulas.
Once more, the check picture is a single uncooked picture developed solely to re-balance the colour and increase the distinction. No darkish frames have been utilized, so the 8-minute publicity at ISO 3200 taken on a heat night time reveals thermal noise as single “scorching pixel” white specks.
Adobe Digicam Uncooked did job smoothing the worst of the noise, suppressing the new pixels however solely by advantage of it softening the entire picture barely on the pixel stage. Nonetheless, it leaves most stars intact.
ON1 NoNoise 2023 additionally did job smoothing noise whereas additionally seeming to spice up distinction and construction barely. However as within the wide-field picture, it did easy out star photographs a bit of, although considerably photogenically, whereas nonetheless emphasizing the faintest stars. This was with no sharpening utilized and Luminosity at 60, down from the default 100 NoNoise applies with out fail. One wonders if it truly is analyzing photographs to provide optimum settings. With no Tack Sharp sharpening utilized, the outcomes on this picture with NoNoise 2023 regarded equivalent to NoNoise 2022.
Topaz DeNoise AI did one other good job smoothing noise whereas leaving most stars unaffected. Nonetheless, the faintest stars and scorching pixels have been sharpened to be extra seen tiny specks, maybe an excessive amount of, even with Sharpening at its lowest stage of 1 in Customary mode. Low Mild and Extreme modes produced worse outcomes, with plenty of mottling and unevenness within the background. In contrast to NoNoise, not less than its Auto settings do differ from picture to picture, providing you with some assurance it truly is responding to the picture content material.
Topaz Picture AI once more produced unusable outcomes. Its Regular modes produced plenty of mottled texture and haloed stars. Its Sturdy mode proven right here did easy noise higher, however nonetheless left plenty of uneven artifacts, as DeNoise AI did in its early days. It definitely looks like Picture AI is utilizing outdated hand-me-down code from DeNoise AI.
Noiseless AI in Luminar Neo did easy noise however inconsistently, leaving plenty of textured patches. Stars had grainy halos and this system elevated distinction and saturation, changes normally finest left for particular adjustment layers devoted to the duty.
DxO PureRAW 2 did easy noise very nicely, together with wiping out the faintest specks from scorching pixels, nevertheless it additionally worn out the faintest stars, I believe unacceptably and greater than different applications like DeNoise AI. For this picture, it did go away primary brightness alone, doubtless as a result of it couldn’t apply lens corrections to a picture taken with unknown optics. Nonetheless, it added an odd pixel-level mosaic-like impact on the sky background, once more unacceptable.

For this picture, it did go away primary brightness alone, doubtless as a result of it couldn’t apply lens corrections to a picture taken with unknown optics. Nonetheless, it added an odd pixel-level mosaic-like impact on the sky background, once more unacceptable. Noise XTerminator did an important job smoothing random noise with out affecting any stars or the nebulosity. The Element stage of 20 I used truly emphasised the faintest stars, but in addition the new pixel specks. NoiseXTerminator can’t be counted on to get rid of thermal noise; that calls for the applying of darkish frames and/or utilizing dithering routines to shift every sub-frame picture by just a few pixels when autoguiding the telescope mount. Even so, Noise XTerminator is so good customers won’t have to take and stack as many photographs.
Conclusion: Once more, the winner was NoiseXTerminator.
Deep-sky photographers have praised “NoiseX” for its effectiveness, both when utilized early on in a PixInsight workflow or, as I do in Photoshop, as a wise filter to the bottom stacked picture underlying different adjustment layers.
Topaz DeNoise can be a good selection as it might work nicely on many different sorts of photographs. However once more, play with its numerous fashions and settings. Pixel peep!
ON1 NoNoise 2023 did put in a good efficiency right here, and it’ll little doubt enhance – it had been out lower than a month once I ran these assessments.
Primarily based on its odd habits and leads to all three check photographs I might not suggest DxO’s PureRAW2. Sure, it reduces noise fairly nicely, however it might alter tone and coloration within the course of, and add unusual pixel-level mosaic artifacts.
Evaluating DxO and Topaz Choices
DxO and Topaz DeNoise AI provide probably the most decisions of AI fashions and energy of noise discount. Right here I examine:
Topaz DeNoise AI on the nightscape picture utilizing three of its fashions: Customary (which I used within the comparisons above), plus Low Mild, and Extreme. These present how the opposite fashions didn’t do nearly as good a job.
The set beneath additionally compares DeNoise AI to Topaz’s different program, Picture AI, to point out how poor a job it’s doing in its early type. Its Sturdy mode does easy noise however over-sharpens and leaves edge artifacts. Sure, Picture AI is one-click and straightforward to make use of, however produces unhealthy outcomes – not less than on astrophotos.
As of this writing DxO’s PureRAW2 presents the Prime and newer DeepPrime AI fashions – I used DeepPrime for my assessments.
Nonetheless, DxO’s costlier and full picture processing program, PhotoLab 6, additionally presents the even newer DeepPrimeXD mannequin, which guarantees to protect or get well much more “Xtra Element” over the DeepPrime mannequin. As of this writing, the XD mode is just not supplied in PureRAW2. Maybe that may anticipate PureRAW3, little doubt a paid improve.
The set above compares the three noise discount fashions of DxO’s PhotoLab 6. DeepPrime does do a greater job than Prime. DeepPrimeXD does certainly sharpen element extra, however on this instance it’s too sharp, exhibiting artifacts, particularly within the sky the place it’s including buildings and textures that aren’t actual.
Nonetheless, when used from inside PhotoLab 6, the DeepPrime noise discount turns into extra usable. PhotoLab is then getting used to carry out all of the uncooked picture processing, so PureRAW’s alteration of coloration and tone is just not a priority. Conversely, it might additionally output uncooked DNGs with solely noise discount and lens corrections utilized, basically performing the identical duties as PureRAW. In case you have PhotoLab, you don’t want PureRAW.
Evaluating AI to Older Non-AI Packages
The brand new era of AI-based applications has garnered all the eye, leaving older stalwart noise discount applications wanting a bit of forlorn and forgotten.
Right here I examine Digicam Uncooked and two of one of the best AI applications, Topaz DeNoise AI and NoiseXTerminator, with two of probably the most revered of the “old-school” non-AI applications:
Dfine2, included with the Nik Assortment of plug-ins bought by DxO (proven above), and
Scale back Noise v9 bought by Neat Picture (proven beneath).
I examined each through the use of them of their automated modes, the place they analyze a bit or sections of the picture and regulate the noise discount accordingly, however then apply that setting uniformly throughout your entire picture. Nonetheless, each permit handbook changes, with Neat Picture’s Scale back Noise providing a bewildering array of technical changes.
How do these older applications stack as much as the brand new AI era? Listed below are comparisons utilizing the identical three check photographs.
Within the nightscape picture, Nik Dfine2 and Neat Picture’s Scale back Noise did nicely, producing uniform noise discount with no patchiness. However the outcomes weren’t considerably higher than with Adobe Digicam Uncooked’s built-in routine. Like ACR, each non-AI applications did easy element within the floor, in comparison with DeNoise AI which sharpened the mountain particulars.
Within the tracked wide-field picture, the variations have been more durable to tell apart. None carried out as much as the usual of Noise XTerminator, with each Nik Dfine2 and Neat Picture softening stars a bit of in comparison with DeNoise AI.
Within the telescopic deep-sky picture, all applications did nicely, although none matched NoiseXTerminator. None eradicated the new pixels. However Nik Dfine2 and Neat Picture did go away needed particulars alone and didn’t alter or get rid of desired content material. Nonetheless, additionally they didn’t get rid of noise in addition to did Topaz DeNoise AI or NoiseXTerminator.
The AI expertise does work!
Your Outcomes Could Fluctuate
I ought to add that the character of AI signifies that the outcomes will definitely differ from picture to picture.
As well as, with many of those applications providing a number of fashions and settings for energy and sharpening, outcomes even from the identical program may be fairly totally different. On this testing, I used both this system’s auto defaults or backed off these defaults the place I assumed the impact was too robust and detrimental to the picture.
Software program can be a always shifting goal. Updates will alter how these applications carry out, and we hope for the higher. For instance, two days after I printed this check, ON1 up to date NoNoise AI to v17.0.2 with minor fixes and enhancements.
And do keep in mind I’m testing on astrophotos and pixel peeping to the acute. Rave critiques claiming how nicely even the poor performers right here work on “regular” photographs would possibly nicely be legitimate.
That is all by the use of saying, your mileage could differ!
So don’t take my phrase for it. Most applications (Luminar Neo is an exception) can be found as free trial copies to check out in your astro-images and in your most well-liked workflow. Check for your self. However do pixel peep. That’s the place you’ll see the issues.
What About Adobe?
Within the race for AI supremacy, one wonders the place Adobe is within the subject.
Within the final couple of years, Adobe has launched a number of wonderful and highly effective “Neural Filters” into Photoshop, which work wonders with one click on. And Lightroom and Digicam Uncooked have obtained highly effective AI-based choice and masking instruments far forward of a lot of the competitors, with solely Luminar Neo and ON1 Picture RAW coming shut with related auto-select capabilities.
However AI noise discount? You’d assume it might be a excessive precedence.
A neural filter for Noise Discount is on Adobe’s Wait Checklist for growth, so maybe we’ll see one thing within the subsequent few months from Adobe to compete with the AI choices of Topaz, ON1, and Luminar/Skylum.
Till then we now have plenty of decisions for third-party applications that each one enhance with each replace. I hope this evaluation has helped you make a alternative.
