Sometimes fine-tuning decreases profile quality. For example, I get 96% quality with Auto-Profiling but it becomes 94% after fine-tuning and sometimes less. Must I use the original one without fine-tuning with higher quality or fine-tuned one with less quality? Also, here's an image of such a profil...

Thanks for answer.

So, can we select just the center square (bigger one)? Also, sometimes I'm getting better results with semi-manuel profiling than "Auto Profile with Calibration Target" option. As I understood, I can't do that, right?

Thanks for answer. Also, can we select ANY square of calibration target as noise profile area?

So, is every square in calibration image is specially designed?

Why are we using calibration target instead of a regular image when creating a noise profile? What will we lose if we use regular image? For example when creating a profile set for my machine, for a profile, I get %78 quality with calibration target (I know, I can improve it.). With a regular image ...

I've made 44 noise profiles with different combinations for Canon SX120. I used automatic white balance for all. Overall profile quality isn't too good (about 70-80%). I hope nothing is wrong. For ISO:80,100,200,400,800,1600 and 1/25 1/30 1/40 .... 1/250. Source image files were 3648 x 2736 pixels. ...
