Ability to use denoise out side of Track in 1.7

I miss the ability to use de noise outside of track in 1.7. It is not something I use often. But, found it helpful in a couple of cases. Other than that I feel 1.7.XXX is a great improvement over 1.6.

Hi Dave,

If you absolutely need to use Denoise, you can simply turn on Tracking, indicate the image is non-linear, have it take into account the sRGB stretch and then Turn tracking off again and do your noise reduction. While perhaps a few more clicks than you are used to, this procedure at least takes into the account the non-linear stretch that the image must have undergone to make it suitable for screen rendering.

Hope this helps!

I also miss the separate "denoise" module. The ability to mask specific areas of the image and apply denoise to that part is something I used often. Maybe you folks can bring that ability back. I am finding myself loading V1.6 to use the denoise module, saving that image, then going back to V1.7 to complete the image.

I have got into the habit of turning tracking on or off as needed to facilitate denoise if I need it outside of regular workflow.

Hi,

You can still do that by using the Layer module (in a more sophisticated fashion as a matter of fact!). In denoise, make sure that noise grain is no longer objectionable anywhere - even if too much detail is removed in other places. After that, simply launch the Layer module and hit Undo->Bg. This puts the non-denoised image (from the Undo buffer) in the background layer. Now you can use the Mask editor to switch between background and foreground as you see fit.
Crucially, you can now also use luminance mask ("Brightness Masks"), as found in many "standard" (non-Tracked) denoise routines in other software.This will let you approximate the non-linear stretch's influence on noise grain a bit better (but of course no where near as accurate as proper Tracking).
Hope this helps!
