Thanks for your images and examples, really interesting. I will need to get my film processed by a lab to get the image files. Can you recommend a file format for me to request from the lab so that I can manipulate the images? (I'm completely new to the post work side of things).
I agree with Kris's response above, ideally an uncompressed file format like TIF but if JPEG one that is saved with a low compression. For reference, a full res 4000dpi scan of 35mm is about 5600 X 3700 pixel size and a 16bit TIF is about 125MB while a 0 compression 8bit JPEG is about 20MB. So if the shot was "properly exposed" and the scan is good, then post work may not even be needed and a relatively low compression JPEG may be good enough for the final use depending on the cost.
For reference, this is a full res scan of Kodak Portra 400 in a highly compressed JPEG format of less then 2MB and I did not apply any post except for crop and text. Depending on final use, would you have needed the full res to adjust grain or sharpness? In your own judgement, would you have needed a TIF file to adjust exposure, color, contrast? Of course getting the full res uncompressed file will allow you to make those decisions after the fact and only you can decide.
