George61d Posted May 31, 2007 Share #1 Â Posted May 31, 2007 Advertisement (gone after registration) Does colour negative film have the same dynamic range as modern B&W film. Â I am very impressed with the amount of detail I can extract from a chromogenic B&W neg in comparison to a standard DSLR raw file, and I am wondering can I get the same from Portra or other colour neg.... Â ...suspect that I may have just answered my own question with the term chromogenic above :-) Link to post Share on other sites More sharing options...

andybarton Posted May 31, 2007 Share #2 Â Posted May 31, 2007 What brand of dSLR are you using as your comparison, George? Â Don't forget that there is a scanner in the system somewhere here (I assume), and the quality of that, the software and the operator will have a huge bearing on the output.

With the scanner and flim I have been able to capture deatil in the highlights that I know would just be blown in any of the DSLRs.  I shoot raw and use either NC, ACR or Lightroom with a low contrast curve (when there is a large DR) for conversion. NC sucks at highlight recovery but the other two are quite good - however they still dont match the film/scanner combo for DR.  For some of the film shots I have used a merge of two scans at different gain settings to pull even more data out of the negative. Of course you can do somthing similar with the digital shots - but I still think the film wins. Link to post Share on other sites More sharing options...
