Re: "What is the best way to scan photos at home if I have hundreds and don't want to stand over a flatbed scanner all day long?"
The honest truth is .... there is no easy way to do this, or at least to do it well.
I have a small business buying, servicing and reselling used Nikon film scanners. These scan negatives and slides, not prints, but I get the same question all the time, and it goes something like this: "I have {hundreds, thousands, tens of thousands} of {slides, negatives or prints} taken over a period of {quantity} decades by my family and it's earlier generations. How can I scan these quickly and inexpensively.
And the answer is, unfortunately, you can't.
QUALITY scanning of photographs (or anything, for that matter) is not just a matter of slapping the media on the scanner glass and pressing a "scan" button and POOF! you are done. Yes, you can do that, but you won't get quality. Scanning is a complex task and the learning curve for GOOD scanning software is steep and requires some understanding of the physics of light, printing, photography and video displays. If the image quality is important, you will want to set the resolution, do a preview scan, manually crop, manually adjust the exposure parameters (typically brightness, contrast and "gamma" (all of which sometimes go by other names)), then do a final scan. You may want to correct color, which is much more involved, and you may want to do post-scan processing with photoshop or another photo editing program to fix any number of different types of defects. You will be very lucky, no matter whether it is film or prints, to average much better than 4 to 6 minutes per image. And if you are talking about thousands of images (and I'd say that most families have that many, oftne going back generations to pre- World War II) .... well, you are talking about hundreds of hours.
There are services that do scanning of film and prints (by the way, if you have the film (e.g. negatives or slides), SCAN THOSE NOT PRINTS ... the quality is MUCH higher, but you need a good film scanner). However, there are two problems with services: The first is cost, if they charge 79 cents per image, which sounds reasonable enough, but you have 2,000 images, suddently you are looking at almost $2,000 (there are "extra" costs that add up) ....... And then there is the other problem, precisely because this is a labor intensive task, most of these services send the originals to 3rd world countries where the labor is cheap, so you photos or film gets a round trip to Haiti or Bangladesh or India or Pakistan .... and sometimes, not often, but sometimes it just disappears.
To be sure, some equipment is better and/or faster than others, but the actual scan time is often only about 20% to 50% of the total image processing time. But don't fall into the trap of buying equipment that either can't do a good job or won't because it needs serviced. I also service Nikon film scanners, and one of the things that I hear often is a half-joking (but half-serious) E-Mail after I return a freshly serviced film scanner that goes something like this: "Damn you, I just got may scanner back, and the images are so much better than what I had been getting that I am now faced with an demanding compulsion to rescan my entire collection. Your "repair" is going to cause me to have to put in hundreds of hours of additional work !!"
As to the equipment: One strategy that works well is to buy a good used scanner, use it and resell it. Although the scanner may cost hundreds to perhaps even $1,500, depending on what you get, this stuff holds it's value well and if you bought it used, you may well recover all or substantially all of your purchase price when you resell it. This is more of an issue with film, however, because prints can usually be scanned well with any really good quality flatbed scanner. As to brands, for prints, I'm partial to Epson and SOME (but not all) HP scanners [avoid any scanner with a "CIS" imaging system]. For film (either slides or negatives), I really think that there are 3 good choices, they are Nikon, Nikon and Nikon, but I am biased and some of the Epson flatbed scanners really can do an excellent job with film (and they may be the only choice if you need to scan film images larger than 35mm). When buying a scanner to scan film, don't even consider a unit that does not have a feature known as "digital ICE". This technology (which uses an infra-red scan in addition to visible light scans) is pure magic producing georgous, defect free scans of even very badly scratched and damaged film. Unfortunately, it doesn't work with prints, black and white film or SOME slide films, but it is just magic with most negative films and most but not all slide films. Digital ICE was a patented technology developed by an independent firm and licensed to many scanner makers, but only some brands (including both Nikon and Epson) offer it, and even then not necessarily on all models of their products.
I hope this helps, but I understand that wasn't the answer that you probably wanted to hear.
