robertochaves Posted August 12, 2015 Share Posted August 12, 2015 Hi,Today I came up with, what I think is, a great idea I'd love to see implemented in Affinity photo. I'd like to be able to get a noise profile on the picture I'm working on, then be able to add noise according to this profile to areas of the image that have been retouched.There was many many years ago (I'm not sure it still exists) a program called Noise ninja, in which you selected a square in the image (like a clear sky patch) to use for creating a noise profile.Then this could be used to remove noise from the entire image.Or you could build a library for different cameras and ISO settings, and just use the exif info to get the right profile. Now, what I'd like is to be able to either analyse the whole image to create a noise profile (the software could try to find areas with little variance automatically to sample, or one could select and area).Then if you work on retouching a certain area you could re add noise to this area.Maybe one could simulate parts of this with the low pass and high pass filters. But I think it would be better for some types of retouching (jewellery photography in my case) where I want to remove small scratches on highly polished parts (that you can't see with your naked eye, but that become quite visible when photographed) where this would be extremely helpful. Have a great day! Ps.
