Topaz DeNoise AI 3.5 mini Review

I just DL'd it. I'd say it is better than the previous version, at least on the Windows platform.

It's still slow-ish on my lower-mid range PC, it took about 4.5 minutes to convert from a 20 pm ORF (ISO 6400) to a DNG.  Image quality is pretty good, I think.   Good enough that I see no reason to switch to something else.  On the whole, I'd have said that 18 months ago, Topaz DeNoise AI was behind DXO in handling raw.

At this point, I'd say it is close enough that it is not a clear-cut choice, certainly when comparing DXO Pure-Raw to DeNoise.  And if you want your noise control tool to also work on bit-mapped photos as well, or add masking capability to your noise control, I don't think any residual difference in Raw output would matter all that much to you.  I'm certain the Topaz generated DNG can be edited into an excellent finished product.

Here is a comparison shot of the "before and after" in ACDSee compare.  These are unedited, except for running the image through DeNoise 3.5. The one on the left is "pre DeNoise"

Below, is a part of the Change log.

Known Issues:

  • Studio 2 integration on Mac requires the user move the .app back to the old location (/Applications/Topaz Labs LLC/Topaz DeNoise AI/Topaz DeNoise
    – This is required because Studio 2 checks this path directly.
    – If you do not use Topaz DeNoise AI inside of Studio 2 as a plugin, please don’t use this path.
