Mohamed Sakr (MohamedSakr) added a comment to T44757: light doesn't appear in camera ray.

@Brecht Van Lommel (brecht) , aha, I misrepresented it as a bug , you may put it as a feature request :)
also I got some questions that I want to ask you about "related to function callbacks that you wrote "write_render_tile_cb, update_render_tile_cb" and "progressive, progressive_refine"

Mohamed Sakr (MohamedSakr) added a comment to T44391: Cycles Image reconstruction Filter, correct sample addition, correct gamma display.

sorry for this, my first test was inside blender "no images saved" , and images were the same, thought it would make the same problem after saving "like in Cycles Standalone" , but the save mechanism is different in Blender and Cycles Standalone.

I can't reproduce it from blender, the saved image is exactly = to the previewed image "in any format" , both appear with linear gamma which gives the user wrong impression "at least when he tries to render in progressive mode to test lights and shaders"

Hey Sergey,

well I consider (1) as a bug because it adds wrong values "if I'm correct" , they should be added in XYZ color space (not RGB)
about (2) it is misleading for the user, user expects an antialiasing filter, here it doesn't do any reconstruction
about (3) again it is for the "correct" color viewing during render, so user doesn't add light to dark areas "while they are not black if they got gamma correction"
