jarrydbekker Posted December 12, 2004 Share Posted December 12, 2004 I recently shot two rolls of Portra 400vs of some friends and their baby but accidentally forgot to change the iso on the camera. I have heard that an over exposed neg can be saved at the lab by asking for it to be procededed differently or it can be adjusted at the printing stage. What will the effect be on the pictures? What could I do to save the shots? Many thanks Jarryd Bekker Link to comment Share on other sites More sharing options...
jim_gifford Posted December 12, 2004 Share Posted December 12, 2004 You do not need to do anything special. You overexposed your shots by one stop. It may seem like a lot to go from "400" to "200" but it is really just one f-stop. For a given lighting condition in your photography, every time your double or halve the film speed, you change the exposure settings in the camera by one stop. You shot 400 film with the camera set for 200 film. That means your camera used f/4 when f/5.6 would have been ideal, or used f/8 instead of f/11, and so on. If you think in shutter speeds, then when the "right" speed would have been 1/125 second your camera was picking 1/60 second. Those one-stop differences are not going to hurt your pictures. Portra (like most color negative film) is very tolerant of minor overexposure. Just have the film developed normally. No adjustments necessary. Everything will be fine.

hsksla_ddygff Posted December 12, 2004 Share Posted December 12, 2004 1 stop overexposure on Portra is fine, not to worry, process regularly. Link to comment Share on other sites More sharing options...
jonathan_traupman Posted December 12, 2004 Share Posted December 12, 2004 In fact, you may like it better shot at 200. I routinely shoot color negative films at 2/3 stop over (160 -> 100, 400-> 250, etc.) and then process normally because it gives more detail and less grain in the shadows. -Jon Link to comment Share on other sites More sharing options...
scott_eaton Posted December 12, 2004 Share Posted December 12, 2004 Rating VC 400 at 200 actually improves this rather unremarkable film. Process normally. Link to comment Share on other sites More sharing options...
berton_chang4 Posted December 12, 2004 Share Posted December 12, 2004 I shot NPH (400) at ISO 200. at least in 6x7 it brings out a wider tonal range for people's skin. don't worry, you might even like it better. Link to comment Share on other sites More sharing options...
