synergy79greg Posted October 21, 2003 Share Posted October 21, 2003 Has anyone pushed any of the consumer Kodak films? I have been normally using 800 mostly with a flash. What are the results of the 800 film being pushed to 1600 or even 3200? Can the slower speed films be pushed as high? 100 to 1600, 200 to 1600, etc. Link to comment Share on other sites More sharing options...
pascal_miele Posted October 21, 2003 Share Posted October 21, 2003 You can psh a 100 film to 1600, 3200 or 6400 and even 450 000 but only if you don't want a picture ! C41 films are not "pushable-films". keep your 800 at 800 Link to comment Share on other sites More sharing options...
scott_eaton Posted October 21, 2003 Share Posted October 21, 2003 Actually *professional* C-41 films push quite well. It's the amatuer ones that don't do it well because they aren't that good to begin with. Link to comment Share on other sites More sharing options...
mike_scarpitti Posted October 21, 2003 Share Posted October 21, 2003 'Pushing' is not truly possible with any film. With C41 films, you're messing up the three colour layers because the time has been worked out for all three layers to coincide. Why do people insist on tryimng to push? If tomorrow Kidak announced a film with 10,000 ISO, someone would say 'Can it be pushed'? The sensitivity of any film is determined at manufacture.

bill_tuthill Posted October 21, 2003 Share Posted October 21, 2003 In Mar/Apr 2001 and again in Sep/Oct 2003, Ctein published tests of C-41 push processing in Photo Techniques magazine. Quote from 2003: <BLOCKQUOTE> Push-processing (a 50% increase in development time) worked equally well with [NPZ, old NPH, and new NPH]. They gained about 1/2 stop of shadow speed, about one grade of print contrast, and a considerable amount of grain. Each shifted about 10CC to the yellow, but there was little problem with color crossover. </BLOCKQUOTE> Link to comment Share on other sites More sharing options...

scott_eaton Posted October 21, 2003 Share Posted October 21, 2003 The reason you push C-41 print films is to gain and extra stop or half a stop in exposure lattitude by sacrificing some grain and shadow detail for added midtone/highlight density. Portra UC, Supra 400, Fuji NPZ.....all are designed to be pushed. These films will do better *pushed* than under-exposed by the same amount, which is what thousands of professional photographers do on a regular basis.

jay ott Posted October 23, 2003 Share Posted October 23, 2003 Mike, To answer your question why people insist on pushing film it's the same reason people overclock their motherboards and CPU's or saw the barrels off their shotguns. Personally I don't push. Although sometimes I may pull a b&w film by 1 or 2 stops. Link to comment Share on other sites More sharing options...
scott_eaton Posted October 24, 2003 Share Posted October 24, 2003 What a stupid analogy. I wonder if Jay knows the number of professional photographers on a daily basis that push C-41 and E-6 films. Perhaphs he should enlighten them that they should really use amatuer C-41 films and not push. I'm not even a full time pro, and even *I* have published images with pushed NPZ.

jay ott Posted October 24, 2003 Share Posted October 24, 2003 Scott, FYI, you were reading more into what I wrote than what actually was there. I was not bashing anyone who routinely pushes their films. Nor did I advocate that they should stop doing it because I said so. I just don't do it too often because I don't find myself in situations where it's necessary. If I did I would do it more. In another thread on pushing I said I can't wait to try HP5 at 3200.

mike_scarpitti Posted October 24, 2003 Share Posted October 24, 2003 You can't push film. It's self-deception. It doesn't work. Never has, never will. Link to comment Share on other sites More sharing options...

elliot_n Posted October 26, 2003 Share Posted October 26, 2003 Mike, it's obvious that you have very little experience of push-processing color negative films. Link to comment Share on other sites More sharing options...

Yes, I wouldn't dream of doing it. I've seen what it looks like when other people did it. Pushing doesn't work, never has, never will. Link to comment Share on other sites More sharing options...

elliot_n Posted October 26, 2003 Share Posted October 26, 2003 'Everybody?' Well, yes - one lab I know pushes all C41 by half a stop. And yes, that does make a difference. Link to comment Share on other sites More sharing options...
