I've recently decided that my parents would love to have their slide collection in digital format, because being on slides means they are never looked at- most are older than I am, yet I don't think I've ever seen any of them. There's a lot. Probably over a thousand. The cheapest I found to scan them was .25$ a slide and most places charge around $1. I have an industrial scanner that scans paper SUPER fast, but that doesn't help with scanning slides. I researched the available scanners for sale and seem to have found that if you want any sort of batch capabilities, you have to pay $600-$1000 at least. I did find ONE scanner that was $250 which had a 30 slide batch tray, but I can't say that I believe it could possibly work well, but I have no idea. I happened across the idea of using a slide projector and carousel to backlight your slides and a mounted DSLR camera with a macro lens pointing into the projector lens. The one I found even made a little circuit to sync the camera shutter with the next slide button on the projector. Scans around 1 per second, much more acceptable than 1-3min per slide.
The quality seems acceptable from the examples I've seen online; in fact, the quality could be considerably less and it would be just fine. Most are not even pictures in which the quality is of that much concern- maybe a few scenery pictures, but most are of people and weren't necessarily the highest quality pictures in the first place.
That being said, I want to do the projector/camera thing because it is quick and seems to provide everything I'm looking for FAR cheaper than buying a scanner that will do it, or paying a service. Only problem is that I don't have a DSLR body NOR any lenses, macro or otherwise.
So I would have to buy a DSLR body and macro lens. This is not a bad option because after I am done scanning, then I will still have a DSLR, though I'll probably want some other lenses. However, a DSLR and lens are not exactly CHEAP; I was hoping to only spend around $200-$300 on this project. Are there any DSLRs out there (and lenses) that would suffice for the job at hand for around that price? My research seems to say that I am going to pay at least $500 to even get one at all. That's cheap, even. Which would be cool, since I'd use the camera after scanning the slides, but I just don't have that much $ right now.
Also, someone suggested that I try using the slide projector to project onto a screen (which I DO already have) and then just set up a tripod and take a picture of the screen. Would this work? Remember, I don't really care about things like proper color representation or high resolution, but I WOULD like to capture the entire slide uncropped. Also, I wouldn't need a macro lens; in fact, it would seem to me that I could just use a regular point and shoot camera so long as it was of enough quality to allow me to set the F-stop, apeture rate, etc... it would also have to have a "remote" for snapping pics, as the electronics to sync with the carousel use it. Thanks in advance. :)
Edit on August 8, 2020 : Well, I have finally found a solution; I just purchased a Nikon D5000 body for $50 and I have this Ambico Deluxe video transfer system contraption I picked up for $7 which is designed to transfer slides to VHS via a camcorder and I am pretty sure I can put it all together with a slide projector and make it work! Once I get everything and give it a shot, I'll return with details if everything goes as expected.
