Hi
As reported earlier v4 is sharpening images when Denoise is used at 0/0 value.
IMHO 0/0 should not apply any changes to the image!
Thanks for checking and improving

The strength is at 1 here, and will have some effect yes. Denoising, even at 1 can help with seeing things as “sharper”, yes. The lowest setting in Denoise possible is 1, that we see here.
Make sure to send details on what you want as a feature request!
Ok, thanks - I would, prefer to have a range between 0 and xy, so I would not have to toggle the effect on and off in order to see the difference.
The feature request is here, make sure to add your vote in! The development team looks at the most popular requests!
To see on/off quickly you can also press the spacebar

Thanks - a slider from 0 to xy would still be easier to handle for the user – maybe not for the programmer?
The spacebar is instant, the on/off toggle is quick too, and the 0 would make you lose your prior setting number! I haven’t seen this be requested but glad to know it could hep your workflow. Let’s see the votes, seeing you added yours in, thanks!
The 0 – xy is Photoshop (and others) standard setting: to the left: no effect, the more to the right: the more effect…
why invent new settings? I do also use the space bar/ on/off toggle as soon as I have found a decent value – just for a quick comparison
