I've played with pretty much any film I come across, and in terms of cost-benefit I've settled on Fomapan films. I like the grain structure, they are some of the cheapest BW film available and have great latitude if you like to mess with stand development. I shot this photo on a Pentax ME camera using Fomapan 100. Developed at home with Ilfotec DDX and scanned with a Canon 5D Mk3 + Canon 100mm f2.8.
Interesting, I've used the dev chart to develop K400 and I thought they were fine, what developer are you using? Although, maybe they are getting overdeveloped and I just don't see it.
