I used to photograph the streets with Ilford HP5 when I was in Ireland. But in Germany Ilford products are more expensive, so I experimented some others brands until find Kentmere, which is also from Ilford but much cheaper. What attracted me to Kentmere 400 was the stony agressive texture I could get developing with Ilfotec HC.
Later on I was reading about Fomapan 400 and searching some examples in the internet I kind of enjoyed its grain but also the texture quality specially for portrait. It is just different, maybe because it still uses a old formula.
After reading several comments about "too much grain on 35mm" and "how it scan bad", among other issues related to it Real ISO, I decided to try because there were very good examples I could find in the internet.
The result of my first 35mm Fomapan 400 developed in Rodinal was better than I expected, not as much grain as I have seen on examples in the net. I actually would prefer more grain at firts but after analysing it I realised the grain characteristic would not look good if it appeared as strong as Kentmere 400, that has bigger grains. It also scanned fairly well.
The main reasons to change from Kentmere 400 to Fomapan 400 are actually two. First of all, the Fomapan highlights looks much nicer. Then It has an old look style that I appreciate a lot. And this old film look is enough to convince me change from the stony big grain Kentmere look. An other possible reason is the look it delivers in low light or artificial bulb light. But I could not confirm it so well.
The best of all is its price. Just a few cents less than Kentmere but a quite considerable difference when we buy packs of 20 at once.
I just love it! But I am still discovering and experimenting with it.
