salvaging under processed images

[esearing]

through a moment of idiocy I failed to mix HC110 to full strength. So my negatives are very thin. They do seem to have some detail. Images were a mix of still life flowers (easily reshot) and landscapes in the mountains. Is there any chance I can salvage these by toning the negative or do I just chalk it up to a learning experience and take a weekend trip back to the mountains? would scanning them reveal whether it is worth the effort to try something like toning the negatives?

film is HP5 and FP4. both rated at 1/2 box speed and process at about 71 degrees for normal box times.

Read up on intensification.

Bleaching and redeveloping with a staining type developer like pyro will bring the density up and can be repeated if the first go around in still too thin. I'm sure theres plenty of detail on the net for you toresearch in this direction, have fun with it.

Scanning can salvage thin negs nicely.

HC-110 comes in a very concentrated form. So are you saying that you diluted it more than necessary?

Just don't do what he's doing in the video...not wearing gloves when using selenium toner. ALWAYS wear gloves and have proper ventilation if you are going to do this...be safe!

Photo-Formulary sells several intensification formulas. Just don't expect a truly beautiful result.

Personally I'd try playing with them in the darkroom.
I've had some soft (Funky) wallpaper like effects with similar negatives in the past.

Yes, I hate to admit it, but I used TableSpoon measure instead of Ounce measure. So I had about 1/2 the HC-110 needed. Some of the sheets did get a minute longer of devlopment and they seem the most salvagable. Contact prints don't have much detail though.

Selenium toning should be the last thing you try, not because its no good but because it is irreversible and none of the other choices will work after doing it.
Try a few cycles of rehal bleach and redeveloping first as suggested above.
You can also try a chromium intensifier if you are happy with handling dichromate and hydrochloric acid. Formulas should be easy to find here or at apug
