scanning old photographs
So, I'm converting all of my photographs into digital. I don't want to do them one at a time since my scanner takes so long to scan, so I'm scanning four or five at a time. I want to cut the resulting image into individual photographs. Is there an easy way to do that? Attached is an example of the bulk photo scan.

RE: scanning old photographs
I have a similar project going for my old family photos but I also scan my store receipts (the ones paid for with plastic) like this. What I do is crop out everything but the one I want, then save (actually export it to JPG) *with a new name* (very important), then reopen the original file, crop the next one, save/export it, etc. - until I've done them all. With the receipts I usually delete the original file but for photos - it might be worth keeping those as backups.

This is the fastest way I know. If you're worried about messing up the original image you could also select the photo you want from the original file, copy it, then open a new image and paste it there, then save/export that. That would keep the original open so you could go back to it as needed. I've done this occasionally but it does seem to be slower.

Those are my 2 methods but I admit I'm no expert. If anyone has any better ideas I'd love to hear them because even when I'm not working on the Family Scanning Project I still have all those receipts to deal with, and any way to make that process more efficient would be great.

Your second method is faster if your careful just to copy an image from your original pasteboard(compilation/scan)
You save having to reopen the original file mulitiple times as you can leave it open.

===============
(Advanced & maybe quick/er way using "Canvas size")
This is a more involved way but mca18974 would be a cleaner way.

1. Copy each photo and paste them as their own layer, (same document)
(This step can be optional, but it makes it easier to isolate one photo)

2. You may need to use the Move move tool to reposition the layer to the center of the canvas before you resize.
- Turn off all the eyes on the layer window *EXCEPT* the image your going to extract.
3. Go to "Image > Canvas size..."
- click the link icon next to the size to lock proportions, bring it down to scale, notice the preview.
- Bring it as much as you can while keeping the height & width in the frame. (none of the other layers will be affected ^_^ ) you can crop it after you save it.
4. Go to "File > Export..." save type as a jpg

5. Repeat steps #2 through #4 for the other layers (pics)

This is fast IMO because you're working in the same document the whole time. The only thing is, you'll need to crop the extracted saved jpgs after because of the way you save it.(& fake cropped it with "canvas size...")

I may do a short video demoing this technique, but no promises...

RE: scanning old photographs
If your scanner does not have the divide function built in, and I can't remember my ancient Canon Lide 30 having such.

There is a script 'divide-scanned-images' that will do this. see:
http://www.gimptalk.com/index.php?/topic..._p__396740
and
http://registry.gimp.org/node/22177

This still works on my linux machine, however a windows 7 or 8 64 bit Gimp - I don't know

but

End of the day, after much testing including timing comparative methods, the best procedure for lots of the same size photos/cards

As Ofnuts previous post,
sort your images into landscape/portrait and process each set
one photo at a time,
butt it up on 2 sides, so guaranteed to be square and in the same position each scan.
set the scan area to the exact size. (one cause of slow scanning is unnecessary scanning of full page)

This is invariably quicker than setting several photos up, scanning, dividing, deskewing, rotating.

If you want to speed up some more and you are using Windows, don't use Gimp, use Irfanview which has an auto-numbering, batch scanning, straight-to-image function.

RE: scanning old photographs
Thank you for all the quick replies! My photographs are all different sizes, and my scanner has no features at all. I can what's on the flatbed and tell it if I want it high or low quality, and that's it. It gives me a pretty high quality scan though, but it takes probably a minute and a half to scan and save the image to a memory card. Because I'm using Ubuntu, my printer just won't talk to my computer so I have to do the scanning the hard way and I want to speed it up as much as possible--hence the bulk scanning.

I'll have to take a look at the guillotine function. I don't have much experience with Gimp, but it looks like it might be promising.

iForStyle007: I think your method might be my best bet though. I've already scanned all my images like this.

Thanks for the help, and I'd be interested to read any more suggestions anybody might have.
