Should I contact the lab?
Recently shot some 120 film with a GW690ii on a special trip. I knew there were going to be some beautiful landscapes/colors and that I wanted to print some large to frame so I opted for the best quality scans I could get.
Specifically the lab I sent the film to offers
Small (6 MP)
Large (13 MP)
XL (30 MP)
XL + TIFF (8 dollars more than just XL)
XL + TIFF was a big added cost, almost $150 more, but I thought worth it as a treat and given my editing goals.
However, when I started editing both the JPEG and TIFFs I realized I wasn’t getting any more highlight/shadow/color detail.
When I dug into the file data here is what I found (in the windows photo properties info)- the TIFFs were much larger files and were uncompressed (as expected). However, both the JPEG and TIFF files both have a bit depth of 24.
I am by no means an expert on this stuff (hence why I’m asking) but doesn’t that mean the TIFF is 8 bits, 3 per color Chanel?
Does that mean the lab just saved the JPEG image as a TIFF file or am I misreading it somehow? Would you reach out to the lab if they were your images?
Edit: the lab uses a Noritsu HS1800
