I have some negatives that I over developed and when I tried to print them they appeared overexposed. All the highlights were blown. They were printed on Ilford Ilfospeed Deluxe #2 RC paper and processed in Dektol. The negatives are very dense. Can I salvage these shots? Someone suggested using #0 grade paper or CF? Someone else said to expose the negatives for a longer time with the enlarger? They were exposed for 7.5 secs. with the results of blown highlights/Over exposed look.
