Thanks, guys.
I had actually made a search on "retouching" and came up with quite a bit to read before I posted this. I found a lot of advice about how to use spot-tone to clone out little dust spots and what I assume as really small areas of a print. I do this as well, and use spot-tone inks and a brush. But, what I didn't find was specific material choices for retouching larger areas on images. I assume that using spot tone inks is the only way to go, and so I set about trying to brush and stiple tones of inks over my area needing help, but was not very satisfied with the result.
If this is the only choice out there, then I will struggle with improving my technique. Maybe it's as simple as a spot pen, but I wonder how the tones can be perfectly matched from a pen system?
At this point, I would prefer to address the print. I don't want to try bleaching back the negative. But, Donald, that information is good to have. This is a 6x6 negative, and would be difficult to mask properly, but I shoot 8x10 and so knowing how to fix a negative is something else that I'll eventually want to look into, I'm sure.
And, again, I'll troll the site one more time for more specific information.
Thanks,
Tammy
