In my own personal attempt not to use Kodak products, I am wondering what works best with Delta 400 in 35mm and 120 ?
In the past I have used xtol but wish to switch to Ilford products. I will still be using Pan F+ and rodinal but I need a 400 speed film for my xpan.
thanks,

Delta 400 has been my standard 400 film for many years. For the past ten years, I've used a similar formula to Pat Gainer's PC as a one-shot, mixing it fresh (it takes literally 2 minutes to mix) before each session. If I am going to be developing 4 120 rolls in the same session (I have a tank that holds 2 120 or 4 35mm rolls), I can re-use the same liter of developer, increasing the time for the second batch by 20%.
The formula is simplicity itself and gives great results--extremely fine grain, great accutance, and long tonal scale. Negs are very easy to print.
I use teaspoon measurements for ease, but I'll include gram equivalents.
1 liter water
1 tsp. (6 g) sodium metaborate
1/2 tsp. (4g) ascorbic acid (Vitamin C powder or crystals)
4 ml 1% Phenidone stock (1 g phenidone dissolved in 100 ml 90% rubbing alcohol.)
Time: 6:30 at 70F. Agitate for 5 seconds every minute.
For slower films (D-100, ACROS, etc.) I increase developing time to 9-10 minutes, or, if I really want the shorter times, I substitute 1 tsp. (5g) Sodium Carbonate (Washing soda) for the metaborate. This is a smashing developer for ACROS.
The cost of mixing your own, besides the two minutes it takes to throw these ingredients into a liter of water and stir, is much, much cheaper than commercial developers. A bottle of Vitamin C powder will last years, as will a small container of phenidone. Arm & Hammer Washing Soda costs about $3 at the grocery store. The metaborate is also cheap and long-lasting from a chemical store, or you can make it yourself. Search this site for Pat Gainer's formula.
