I recently acquired a Beseler Dual Mode Slide Duplicator from eBay model 4100. I've played around with it some and I'm ready to start batch processing my 35mm slides and 35mm color negatives to RAWs. I have a few questions from those that have used this unit before I spend a lot of time on batch camera scanning.
1) When scanning my slides and negatives, do you adjust the focus for each individual shot or do you adjust the focus once and batch photograph the slides? Maybe the focus would depend on the thickness of the slide mount? I would expect live view would be helpful in the case of focusing.
2) I had planned on using the bellows with the included Nikon EL enlarging lens. In another thread (http://thedambook.com/smf/index.php?topic=3959.0
), it mentions a universal camera mount that allows you to use a macro lens without the bellows. Is this the preferred way of camera scanning or does the bellows and enlarging lens work better? If so, I've never seen this universal camera mount mentioned before; where can I get one? Nothing came up on a Google search.
3) I have both a D700 and D300. Is there any advantage to using the D300 because of the DX crop using the sweet spot of the enlarging lens?
4) Do you find auto white balance works best or do you set your white balance for incandescent? I assume incandescent is the correct color temp for the bulbs.?
5) I've used my unit for less than 1 hour and I've already blown a bulb. On a whim, I took my unit apart and measured the voltage coming out of the lightbulb socket. I measured it at 120V which strikes me as odd given that 82V, 250W bulbs are the correct bulb type. It would seem that 120V is way too much for an 82V blub. Has anyone else observed this with their units? Do you find the Beseler Dual Mode Slide Duplicator goes through bulbs quickly?
Thanks for all your advice!
