a few 'Architecture' taken in New York with my Pentax P30n + 2004 dated Ilford Delta 100 which I processed in my 'Home-Made' Microphen Formula 1+1 . I used a Carl Zeiss Jena 24mm f2.8 Pentax-A
Trask: My home-made 'Microphen' on some other Forum is said to be the Ilford 'Autophen' Formula for machine processing but I'm not sure. I find I have to cut the times compared with Ilford data on Microphen 1+1
Sodium Tripolyphosphate 3.4 grams
Sodium Sulphite anhyd 100.00 gms
Sodium Metabisulphite 0.65 gms

I use filtered water or you can use distilled water then the water softener Sodium Tripolyphosphate is not needed ( I don't have any)
