I am not sure if this has been mentioned before,probably it has, in which case it will just be a reminder.
Do not consider this as a high grade scanning procedure, but for those of us who do not own a scanner wich has the capabilities to scan 8x10 transparencies, they can still see what's in the negative by scanning the negative in reflective mode, prior to adjusting the density of the scan with levels or whatever your software allowsand then revert the image in photoshop.
I repeat, this is not good for high grade work, but it's not bad either.
The image attached is a sample.
