Delta 3200 in 510-Pyro (1st run) & Tri-x in Diafine comparisson

I've just made a couple of prints from a 35mm roll of Delta 3200 developed in 510-Pyro, and I thought I'd share the results.

If I recall correctly (I know, KEEP NOTES :rolleyes: ) I developed the film for 9 minutes at 72 F. The film is a bit under developed, and next time I'll add 2 minutes and see how it goes. E.I. was 1000, exposure was decided by the center-weighted meter on my Canon T-70.

These are straight RC prints with 45 magenta filtration (a lot more than most of my 510-Pyro negs have had so far).

I've included a bigger crop from the napkin to show the amount of detail the print has.

These prints are grainier than what I'm used to getting from Tri-x in Diafine (e.i. 1250). See the last photo for comparisson (the boy studying).

Bottom line (until further testing): Tri-x in Diafine seems a bit better for now, but Delta 3200 gets hand inspected in airports with no questions. Tri-x gets x-ray again and again, regardless of your pleads ("But sir, it says 400 speed").

I develop 3200 in a developer that like Diafine is rich in sulfite. I've been thinking of trying a non-solvent developer for a more defined grain effect. Could you post a larger scan of one of your pictures, so I can get a handle on what the grain looks like?

Sure, here's a larger scan... APUG limits attachments to 700x900 images, so I had to crop the image a bit.

By the way, I've done an exceptionaly crappy job at getting the tonality right in these two scans, but for "size o'grain" concerns they should do a fair job.

I hope this helps,
