I love NLP and this community. Just wanted to get that out there. I apologize in advance for the length of this post and any confusion caused by it. Thanks in advance.
My questions come from the perspective of someone who shoots a ton of medium format with the occasional 35mm. With 35mm my Canon 5D3 and macro lens (50mm f3.5 macro FD Mount via adaptor) can capture the entire frame and border without issue.
As far as medium format goes, I initially just reframed and shot the negative in a single frame. Then I got to thinking that I’d lose some of the image quality and ability to print large which are big reasons to shoot medium format to begin with. Not to mention the corners on this lens would cause the image to vignette. So I began shooting 4 RAW images per frame (6x6 and 6x7) then merging in LR. The problem is that the DNG files were 200+ MB and that’s too big for me. So I began to export the DNG as a JPEG with 100% quality and 600 DPI which yields files in the 12-17 MB range. Only then would I apply NLP so that I could have the option to convert again (in my early trials I converted the DNG then exported the positive JPEG but I like having the option to reconvert/edit within NLP).
My questions are:
-Is there a better workflow for medium format negatives?
-Is it better to stitch 4 frames then downsize rather than capturing the entire frame on a single RAW image? Is that just more work with no net benefit?
-Should I upgrade to a modern macro lens (EF Mount) or is my older lens not an issue?
-Is it better to convert the DNG file then export the completed JPEG or will an unconverted JPEG render similar results when NLP is applied?
