Re: [Digital BW] 8 bit to 16-Canon G2 is 16 bit
2002-05-27 by Truman Prevatt
Speaking of Canon, I converted some raw files in 16 bit linear (gamma=1) the other day. I then went to change the gamma in Photoshop 7. I couldn't for the life of me find where theyh put the gamma adjustment. Used to be in image>adjustment>gamma. That's where the online help says it is. It's not even covered in the paper manual. I'm sure it used to be there in version 6. Am I going nuts or did they hind it someplace just to keep me confused - not hard to do these days. Thanks Truman jimhayes361 wrote:
