Luigi Castellitto Posted November 10, 2018 Share Posted November 10, 2018 Some rumors say that it is possible to develop the film for intermediate negatives Orwo DN2 as if it were a positive for normal projection. It's true? http://www.filmotec.de/wp-content/uploads/2010/08/V-I-TI-DN2-e.pdf Thanks. Link to comment Share on other sites More sharing options...
Premium Member Simon Wyss Posted November 10, 2018 Premium Member Share Posted November 10, 2018 DN is the abbreviation of Duplicate Negative. You have the technical data at hand, there you read the film has a tinted base. Of course can you develop DN 2 to a usefully contrasted positive but the grey base stays. As with all positive images on dyed-base films you want to compensate for the light loss. The additional light washes out shadows. Films have a limited amount of silver on them. You can only develop out the maximum possible density. That is about log 2.6 or 2.7 according to the FilmoTec data sheet. Regular print films yield densities of log 3. In other words, DN 2 cannot bring the same brilliance PF 2 does. For a printing alternative better try out ORWO TF 12 That pulls up to log 4.8 or 4.9. But it is quite contrasty, so a different-than-usual development is needed. Link to comment Share on other sites More sharing options...
Premium Member Frank Wylie Posted November 11, 2018 Premium Member Share Posted November 11, 2018 I use a lot of DN2, PF2 and TF12d; why try to pull a print using DN2? DN2 is a good dupe negative stock; a bit more contrasty than Kodak 2234, but still very good. TF12d is only used in our lab to make dupe negative tracks and we process it at 2.40 gamma in the positive developer to give it the proper contrast for Variable Area tracks. I would never dream of printing a continuous tone image on this stock without a lot of expensive testing and, perhaps, flashing; it is just too contrasty. PF2 is a very good print stock and it makes fabulous prints! The snap is incredible; especially when printing directly from a nitrate negative! DP31 is a good interpositive stock, but I do prefer Kodak 2366, as it has a longer grey scale. Link to comment Share on other sites More sharing options...

Luigi Castellitto Posted November 12, 2018 Author Share Posted November 12, 2018 What do you think of DP3? I know it should be the predecessor of the DP31. For an experiment, would it be possible to shot it directly in the camera and develop it for projector? How many Asa would be indicated to do it?

Premium Member Simon Wyss Posted November 16, 2018 Premium Member Share Posted November 16, 2018 ORWO DP 3 and ORWO DP 31 are the same, photographically. The difference is that DP 3 is on a grey TAC base, DP 31 has a colourless polyester base with an antihalo undercoat. Link to comment Share on other sites More sharing options...
Luigi Castellitto Posted November 17, 2018 Author Share Posted November 17, 2018 Thanks Simon, I have about 7 meters of this film (DP3) in Double 8, I'll see how I can use them. Link to comment Share on other sites More sharing options...
