hello
one good way is to use paper developer like dektol 1+3 or d-72 1+1 or multigrade 1+3, temperature 22ºc and around 5 minutes for tmz @1600, you won´t get reasonable shadow detail so increasing contrast on the printing stage can help to make the grain look more visible and sharper, contrast will be a bit on the high side, but you have to deal with these things.
another way is to use the only developer formulated especifically to do this: FX-16 by Geoffrey Crawley
it takes glicyn, so i did not use it often, it goes bad relativelly fast, but the results are better, less mushyness and more aparent sculptoric quality, it is a FX-2 derivation.
another good way is to enlarge..., use a fast film with good old rodinal and instead os using a normal lens use a wide angle and enlarge in the enlarger the smaller portion in the neg., it´s the easyest way... but you also lose some resolution
good work
