evan_parker Posted March 30, 2003 Share Posted March 30, 2003 OK, I'm a little crazy, just so you know. Anyways, I have some good old Plus-X sitting right here next to me, along with some Delta 100 (damn tabular grained films, whippersnappers) just begging to be tortured. They're masochists, you could say. Cold storage does weird things to the brain. ANYWAYS: If I pushed one of these films crazily high, like five or six stops, what would the results look like? I'm not expecting Cartier-Bresson or Minor White here. I know these negs will be very, very strange looking. But how will they change? Atomically contrasty? Grainy as central Kansas? These could be effects that I actually want to achieve. If you reply, you will be entered into a drawing for free Little Debbie Zebra Cakes... "Get some Stripes!"

gareth_harper Posted March 30, 2003 Share Posted March 30, 2003 Don't know, but why bother when Iford 3200 works quite well at 3200 and 6400 developed in LC29. I've heard of medium format users pushing it all the way to 12,800. Link to comment Share on other sites More sharing options...

al_kaplan1 Posted March 30, 2003 Share Posted March 30, 2003 Generaly speaking, areas below a certain minimum threshold exposure won't have any image at all, just maybe some residual fog density. As you increase development time the contrast will increase as the more exposed an area is the more it will be developing. Grain too will increase, but to some extent this is self limiting. Plus-X grain will be smaller than Tri-X grain when both are overdeveloped. Keep in mind that you're thinking of rating Plus-X in the range of 4,000 (5 stops) to 8,000 (6 stops).At that E.I. you'll only get an image of the brightest highlights, possibly OK for surveillance but little else. If you want big grain start with grainy film, Kodak TMZ or Ilford 3200. If you want grain AND contrast make a Kodalith positive and internegative. Have fun!

eric_burgess Posted March 30, 2003 Share Posted March 30, 2003 I just used some Plus-X at 1000 (3 stop push) - I ran out of TMZ and decided to try it - I developed it at 24 mins with D-76 straight. It came out suprisnigly low in grain (actually less than TMZ), but pretty high contrast (no suprise). The negatives were a little tricky, but printable on grade 1.

chris_waller Posted March 31, 2003 Share Posted March 31, 2003 Try devving in Ilford PQ Universal print developer diluted 1+3 for 12 minutes at 24 C. Link to comment Share on other sites More sharing options...
mike dixon Posted March 31, 2003 Share Posted March 31, 2003 Basically, what Al said. I've pushed Delta 100 a couple of stops, and there was very little increase in the grain. The big difference will be the lack of shadow detail. With massive underexposure, expect thin, low-contrast negatives, even if you develop the living hell out of them.

roger krueger Posted April 14, 2003 Share Posted April 14, 2003 Only 12,800?? I've rated Delta 3200 to 25,000, development extrapolated to 50,000 (in standard X-TOL), and gotten a usable neg or two. (on 6x9) At this high a contrast, realize that you probably have less latitude than slide film--bracket! Link to comment Share on other sites More sharing options...
