Frame coverage influences image contrast and colour cast
PostPosted: Tue Sep 13, 2016 8:01 pm
Hello everyone!
I am a new user of Silverfast HDR package. My main objective of purchasing this software is to obtain a consist and faithful base negative to positive conversion of a selection of film stocks that I use. I will then import all of the conversions into Lightroom for further fine tuning and subjective image controlling. I use a DSLR to digitalise all my films and then use MakeTiff to convert them into linear TIFF files. I then import all linear TIFFs into Silverfast HDR to make conversion. However, I realised there are significant contrast, dynamic range and colour cast differences of deploying different frame coverages, e.g., frame outside the picture or inside the picture. Please see screenshots.
I understand the correct way is put the frame inside the picture but some particularly underexposed images has unnatural boost in contrast and saturation. In some cases when a well exposed film scan is converted with frame inside the picture. It often gives subtle increase in contrast and colour correction which results are satisfactory.
So my question comes back to my main objective. What is the correct way / process to obtain a consist and faithful negative to positive conversion in Silverfast HDR? Particularly with DSLR digitising method. Is there some setting that I am missing?
Many thanks
