Hi everyone, I just started trying to create a digital negative for the first time. Using photoshop on a Mac (am older version, CS3), I went through the usual protocol as I've understood it and everything worked pretty well, but there's one thing I'm not understanding. Using the 'fill' function at a relatively low opacity (10 or 15 percent) in order to colorize my negative (in an auburn tone) results in blocked up shadows - in other words, the parts of the negative that should be clear are also colored in a very light shade. Moreover, the highlights seem to take on color as well. Ideally, I would think that clear shadows and at least some black in the highlights.

With a lot of contrast control via the curves I was able to get a decent negative, but it took a lot of work. Ideally, I wound want my negative to look something like the one in this video: https://www.youtube.com/shared?ci=J3v4M0duCBI
Can anyone point me in the right direction?

Thanks, Paul
