Originally posted by LesDMess I am sure you meant this as a very broad generalization but certainly it depends on what film, how much underexposure and the scanner.
For instance below is Kodak Portra 400 and I shot a few frames thinking I could capture the full range of it's latitude by over and underexposing so many stops.
These are unenhanced - no pre or post scan work, other then cropping and putting them together. In scan, I could have overexposed the darker frames or underexpose the brighter frames to retrieve more color info. And of course I could have also applied addtional post processing to enhance the color info further.
I did actually mean that, because I aim for 3 meters print size, even if I use that capacity less often than 2/3rds meter print size. Mainly, I just want to get the metering right more often. Its a goal.
But, your comment is really good!
The Kodak Portra 400/800 (same film) is non-blue and has broader latitude.
Instead of 3 meters, it can do 4 meter sized prints if the exposure coddles the scanner.
The double price is not a real thing, because it is a bit more likely for a successful image.
I'm so grateful that you've mentioned it.
However, the need of good exposure is a real thing. Portra just does either better or bigger.
I am in need of some wall prints, so thanks again for recommending the right film for that.
