I’ve revised my notes on gamma correction following more research. It seems that most digital cameras, including the 10D, produce images in the sRGB colour space by default. This colour space assumes a display gamma of 2.2, which means that there should be no need to correct the gamma of such images.

The confusion on my part is mostly born from looking at images on a Mac, which applies an automatic gamma correction factor of 1.4, and so made several images look significantly different. I have several photos that on my Linux desktop seem under-exposed, and yet on a Mac laptop look good.

Hopefully my understanding is right this time…
