I'm sorry for the bad title but I have no idea how to describe it better. Basically I wanted to export a very simple blender render as an EXR and than composite it in AP. All of that worked as I had hoped but when I tried to convert it to 16 or 8 Bit (because I wanted to export as a file format that my drawing program can use) something happened that I just can not understand. This is (1) what the composite is supposed to look like, (2) What it looks like after I converted to 16 Bit. (3) The Layer that seems to me to cause the problem (first is in 32Bit, second in 16Bit)
This is the file: sphere16bit.exr
Now what I don't understand is how its possible that if I merge the layers together and then convert to 16Bit everything looks the way it should but it doesn't work if I convert everything "individually". Also I don't get how if I convert it back from 16Bit to 32 it looks correct again. I'm pretty sure this is just me not knowing what's going on but I really want to know if there is something I can do to keep my layers not merged but also convert to 16 / 8 Bit while still having it look the way it should.
