I'm just trying to get my head around ETTR as a general concept. Still not sure if it would actually benefit me. One think that has cropped up and slightly confused me is colour space, I can't seem to find much information about what it actually is. I'm using an OM-D and I use Aperture for PP (On a macbook). So do you know: should I be using sRGB or adobe RGB? And why?! Thanks.
