you can adjust each and every ctl available via the v4l2 driver from within Gem. see the [pd properties] subpatch in the help for pix_video. the ps3eye gives me 10 controls with stock drivers (none of them dealing with color correction, if they are labelled correctly). i haven't tried the patch at [1] for a long time, but i remember having good results "back then" (i mainly needed it the patch for being able to adjust the imagesize/framerate, but it seems that it also allows some color correction) fgmasdr IOhannes -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAk7EwKQACgkQkX2Xpv6ydvRu1wCgsU5vX2ya7ilhDW6CoJjWUbJ6 3ncAn1/DWFmjCugudBy61kYteqG1L9Jt =N3Gw -----END PGP SIGNATURE-----
