I've just developed my second 120 film and made a huge faux pas/cock up. I only put slightly more developer mix than what's needed to develop a 35mm film in the tank. I had a bit of a 'blank brain' moment and got the quantity wrong. Conesquently, the images are 7/8 developed and 1/8 under developed - is there any way of rescuing it??? Wouldn't be so bad but there's a couple of 'top' pic's on there where all the elements came together just at the right time.
