There’s quite an exhaustive thread on the practice of colour profiling, perhaps you’ve seen it. Many different opnions expressed there. > [@Color Management/custom profiles at capture - slides](https://forums.negativelabpro.com/t/color-management-custom-profiles-at-capture-slides/5161): > > Hello, I am digitizing many thousands of professional slides from a photographer’s archive. How do people implement color management? (ex: X-rite Colorchecker, LaserSoft IT8 transparency/reflective targets which sounds extra useful for me, etc). I would like to make color profiles for the camera + lens + light source + film stock but not sure where to begin. I am struggling to get a strong common baseline that does not take a TON of work to only barely come close to match the original, which … I was wondering, given that the heat is a price worth paying for you, what shutter speed are you able to use? I use a Cinestill CS-Lite and for 35mm slides I’m using around 1/160 at f5.6 at 200 iso. It doesn’t get hot at all, the Ipad wall adapter does get a little warm. I’m in no way suggesting that this compares with the quality of your light source, just wondering why yours needs to be quite so bright (and hot). --- _[View the full topic](https://forums.negativelabpro.com/t/suggested-backlight-sources-for-scanning-film-with-dslr/130)._
