I disposed of my scanners (two monster SCSI beasts I had to give away) and set up a copy stand for prints. In the past I had digitized a few negatives and transparencies by shooting up into the enlarger with a digital camera mounted at the lens stage. Now I have moved up to a 24MP Fuji and figured I would set up to use it on my two Beselers, one a 4X5 with color head and the other an 8X10 Beseler conversion.
First I put a recent 8X10 negative in the 8X10 cold light Beseler and exposed up with the Fuji kit zoom. For a first attempt I thought the result was pretty good and even posted it here on the bridges thread. See below. Then I bought a used 50mm Micro Nikkor and Fuji adapter, thinking it would be much sharper, and it was, but that's when I first noticed the banding running across the image. Like what we used to see when televisions were recorded on video. For some reason it's not as noticeable with the Fuji AF zoom lens, but it is there. I tried different settings in the camera menu to no avail. Then I just put a negative on my fluorescent light box and sure enough there it is. On the color head with halogen bulb there is no problem. I guess I'll have to digitize the 8X10s on the copy stand over a continuous light source or electronic flash. Sorry I don't have an example of the banding. I deleted them all but I can set it up to occur again. I'd like to know if this problem is unique to Fuji sensors or if it has been encountered with other types as well.
Has anyone else experienced this? I don't think LEDs are the answer unless running off a battery or a very well regulated DC supply.
