I have been digitizing my 8x10 negatives by taping them on a white piece of plexiglass that I have taped to my living room window and then photographing the negative with my digital SLR. The quality isn't great but it's good enough for web-sized versions I can send around to friends.
This process works fine for black & white but I'm having trouble correcting for the orange mask for my color negatives. I don't have any scanning software, just Photoshop. The orange becomes blue when I invert and I try to dial it down but it keeps looking weird. Here's an example of my first attempt at doing this:
Are there any downloadable actions or Lightroom presets or free plug-ins that can automatically correct for this? Any suggestions for how I could better tweak this manually in Photoshop [it's not my strong suit].
