Hi- new guy here.
I have thousands of slides from the golden age of film photography of course now I am thinking of updating them to digital format. Wondering if anyone has projected them on a wall or screen and shooting them with digital camera. Might be faster than s scan them with scanner I would need to buy. Quality of scan less important than maintaining the image.
Thanks

The best quality is achieved with a very high resolution, dedicated film scanner. 4000 or 5400 pixels per inch minimum, 16X oversampling. Yes, it's slow. And, a good one is pretty expensive. Up to 9000 or even 10,000 ppi is possible, but those are very expensive and even slower.
But, quality scanners are widely available used... Buy one, do the scans, then sell it off like other people are doing. With careful shopping and a little luck you might even recoup much or all of what you spent.
There are dedicated film scanners with bulk feeders, that can handle 40 to 100 slides at a time automatically. Load em up and set them to run overnight.
I use a Nikon with a separately sold, accessory feeder that accommodates up to fourty mounted 35mm slides (not needed for unmounted 35mm slides or negatives singly, or in strips or rolls). At max quality settings it takes 5 or 10 minutes per image to make an excellent 4000 ppi, 16X scan. The end result is a very large 130 MB 16-bit Tiff file. Higher resolution models (Minolta 5400, Imacon 9000, etc.) will make even bigger image files. Newer ones might be faster, but high-quality, over-sampled scans take time! For example, the following images were scanned with my Nikon 4000 from Velvia 50 or 100 or Ektachrome 100 slide film (I forget which). I've printed them and many other slide scans as large as 11x14 and 13x19"...
Some flat bed scanners do pretty well, too. Epson V600-V800 series is popular, for example.... You can scan a batch of slides all at one time, making one big (gigantic?) digital file that you later separate. These work better with medium and large format film, than with 35mm. Resolution is typically a bit lower than dedicated film scanners, though. And because the slide or neg is being scanned through a glass platen, there's somewhat lower quality than a dedicated film scanner.
Software that's used with the scanner - flatbed or dedicated film type - can be very important. The original Nikon software that came with my Nikon 4000 fifteen years ago is incompatible with today's operating systems. But new software is available... I've used Vuescan and Silverfast, both of which work well. Vuescan is fairly basic, while Silverfast is very high-end and rather expensive.
An alternative is an "old school" type slide copier rig, used with your digital camera and a macro lens. This can work pretty well, depending upon your camera and lens.
Almost certainly any of the above will do a lot better job than projecting the image and trying to photograph it. Doing that introduces an additional lens, ambient light, the wall or projection screen and other variables... all of which might seriously effect quality.
There are low-cost dedicated film scanners.... some under $100. They're generally a waste of time and money. Most will only generate a small JPEG file, with which you might be able to share the image online in small size, at low Internet resolutions... or make a lower quality 4x6 print, but not much larger.
One other thing you might consider is a scanning service. The price for that varies a great deal, depending upon the quality you need. For simple "family album" type shots, maybe all you need are lower resolution, 25 cent scans. Or for high-end uses, to be able to make large, museum-quality prints, you can easily spend $100 or more for per scan. Even so, outsourcing might be the easiest and most cost-efficient way to get the work done. You can pick and choose among your slides, do them a little at a time and/or in different qualities depending upon the particular image.
