Patches while using Gamma 2.2

Hello All,

Actually I recently started working with gamma 2.2 linear workflow ,did a render and got black patches when opened in photoshop .

Can anyone help out .

Thats not gamma isue. To me it looks like you are clipping the colors in your image.

Are you using exr or hdr images as output?

Or simple JPG?

For a correct flexible linear work flow you need to save your image at float point

Don't know how to work on exr file which is supposed to save finally ..please help ..

It May be noice. You Will increase your noice threshold 0.005

When you save to EXR you need to Override the output gamma to 1.0 in the save menu. There are other ways to do it, but this is the most straight forward.
