Apply red channel to all channels

Hey guys,

So I have this exr image which has information only in the red channel. I want to create a png/tga from it but would like the Green and Blue channel to have the same information as in the Red channel.

Any thoughts?

Something like this:

Code: Select all

convert in.exr -channel R -separate +channel -duplicate 2 -combine -set colorspace sRGB out.tga
