Recipe for Delta 3200 at 100 ASA

[marameo]

Hi, I would love to shoot Delta 3200 medium format way overexposed just to see what kind of grain I can get. It is said that the more you underexpose and push the process, the more graing you end up; I don't see why! I think most of the time grain in just a scanner thing (digital noise). How can there be grain in underexposed and thus thin negatives? I think grain should occour in thick, dense, negatives.

Anyway, I have HC110 and am considering a very short developing time something like 1+32 at 20° for 5 or 6 minutes. I can always extend that to 1+47 for 10 minutes to get more acutance.

I am going to have some frames enlarged in the darkroom to check the result.

What would you suggest?

Thanks

Both overexposed (EI 100 is overexposure, not under) and overdeveloped negatives have bigger grain. Try a paper developer instead of HC110: this will lower the speed as well as giving bigger grain. But the negs may be too thick to scan.

Cheers,

Yes, I mean EI 100 as overexposure, in order to get a dense thick negative. What paper developer would you suggest?

Thanks

Hard to say: it'll be a matter of experiment. Just about any will do, at anything from a half to a tenth of the strength you'd use it for paper, with a development time of 5-10 minutes. Sorry I can't be more helpful. I've not doe this in decades. I seem to recall Ilford Bromophen at 1/2 or 1/4 paper strength for 5-10 minutes, or for something easy, try Ilford PQ Universal at 1+19.

Cheers,
