Hi, Does anyone have any experience converting CMYK images to RGB/web
using rmagick/mini_magick/imagemagick?
I'm finding that the resulting RGB images look completely different,
they seem to have a green tinge...
fyi, I'm converting using -colorspace RGB, and I'm using imagemagick
directly because the other 2 options seem really slow (by a factor of
20 or so).
I have looked into color profiles, but after trying a few via command
line I noticed that I can't use the same profiles for all of the
files. Is there any good documentation out there about color profiles?
or is it a bit hit and miss.
I'm a bit of a beginner at this image processing stuff so I might need
a bit of explanation

I recommend asking on a rmagick / imagemagick mailing list.
Yeah you make a good point I was kinda just putting feelers out
everywhere looking for anyone who had been through what I'm going
through and could give me some pointers!
Having said that, I have partially solved my problem!
I wasn't having any luck with profiles because I didn't have a package
installed called lcms or "Little cms". Imagemagick uses this to
convert things via color profiles
fyi, if anyone is having trouble with this (on a mac) then you should
install imagemagick via the following command:
sudo port install imagemagick +lcms
I haven't tried it on ubuntu yet but it's bound to be similar
