I often get roped into taking shot's of artwork for an artist friend. she works in all sorts of media. Sometimes, I use natural light, sometimes studio gear and grey cards for white balance. What I find is that the colour is never completely right. This bothers me more than the artist.
I understand that there are many steps where the colour can deviate from the real thing. I haven't found any decent guides. I use the D800, C1 and then PS.
Any suggestions, please?
