Does anyone know of any film like Ilford Ortho in 5x7 size? I am currently cutting down 8x10 to 5x7, but would like to get it in 5x7.

Also, does anyone here use Ilford Ortho much? I have rather contrasty negatives that I want to make an interpositive for. I need the interpositive to be of much lower contrast. I have done some experimentation, but could use some advice. I have ordered some ID-11 and will try more dilute solutions and lower development times, but some good advice would save time and money.

My original negatives are of a contrast range of about 1.25. I need to get the interepositive down quite a bit.
