I shot off a roll of high resolution cms20 ii film exposed at 10 iso and processed it in rodinal at 1:500 dilution at 17 degrees C for 2hours using stand development. I wanted to see whether I could get a range of tones without using the expensive adotech IV developer. The negatives were very thin and the developer exhausted itself in the highlights giving a brown colour to them. However the negatives exhibited a good tonal range. I have attached a photograph taken with my 100mm macro rokkor at f/8 with flash lighting of a hoverfly on a native (Australian) white frangipani flower.
