How do you know when the lamp is going out?
Thanks for the tips and pointers for scanning in my last thread here. Lately I've been shooting a lot of medium format, scanning with an Epson at school, and getting fabulous results.
But going back to 35mm, my scans are still being difficult. Namely that I get a very compressed histogram and murky images, even with decent negs.
To recap: I'm using VueScan, a Minolta 5400 (first version, which I'm certain is a cold cathode tube) and the lock exposure technique.
Right now, I'm using a borrowed Coolscan 4000 to do some big batch scans and they're turning out just fine. Could it be that my scanner's lamp is on its last breath? How would I figure that out, and is there any possibility of replacing it?
