igord Posted June 3, 2004 Share Posted June 3, 2004 Hi, Has anyone pushed 400NC for portrait/people and can upload a sample file? Link to comment Share on other sites More sharing options...
elliot_n Posted June 3, 2004 Share Posted June 3, 2004 Looks good at +1 and +2 (rated at 400). Link to comment Share on other sites More sharing options...
jeff_drew4 Posted June 5, 2004 Share Posted June 5, 2004 I have not pushed 400NC because I can grab a roll of Portra800 out of my freezer. I regularly shoot both in 35mm and 120/220. 400NC has plenty of latitude to handle a push, but I recommend professional processing & printing. See Kodak's website for specs etc. Link to comment Share on other sites More sharing options...
the_macman Posted June 5, 2004 Share Posted June 5, 2004 Who says Portra 800 is 800NC and not 400VC or something between the two ? Link to comment Share on other sites More sharing options...
the_macman Posted June 5, 2004 Share Posted June 5, 2004 and not "800VC". you got me. Link to comment Share on other sites More sharing options...
bill_tuthill Posted June 6, 2004 Share Posted June 6, 2004 Igor, according to Ctein's tests in Photo Techniques magazine (don't have issue's date at my fingertips), 400NC gained no additional shadow speed from push2 processing, just extra contrast and grain. For this reason I never tried it and consequently lack sample images. Link to comment Share on other sites More sharing options...
igord Posted June 6, 2004 Author Share Posted June 6, 2004 Thanks for input. Bill, I want extra contrast, especially "edge contrast" and not oversaturated skin tone. I will do some experiments by myself and post the results in a different thread. Link to comment Share on other sites More sharing options...
elliot_n Posted June 6, 2004 Share Posted June 6, 2004 my favourite is 400VC pushed (rated normal)... UC looks whacked, though might suit certain applications... also worth testing on different paper grades (Portra, Supra, Ultra)... Link to comment Share on other sites More sharing options...
bill_tuthill Posted June 7, 2004 Share Posted June 7, 2004 Here's what Ctein wrote in the Mar/Apr 2001 issue of Photo Techniques magazine: "The two Portra 400 films [NC and VC] benefited least from push processing. Both gained 1/3 stop or less in speed; it was only their increased contrast that made underexposed negatives on these films print well. Given the deterioration of image quality with push processing, there is no reason to push either film except to gain contrast." Of course this is the same Ctein who found old NPH to be faster than 400 speed, cough cough. Link to comment Share on other sites More sharing options...
igord Posted June 7, 2004 Author Share Posted June 7, 2004 Will see, I will try it by myself but I wonder if one stop pushing will be that much visible? Link to comment Share on other sites More sharing options...
elliot_n Posted June 7, 2004 Share Posted June 7, 2004 It's very visible. Test at +1, +2 and +3. 'Image deterioration' is negligible. (Unlike Ctein, I'm talking about pushing film that has been exposed at its rated speed.) Link to comment Share on other sites More sharing options...
