How to scan many photos at once on a flatbed scanner
"I am in the situation that I have too many photos to scan, and the problem is that pro scan would cost me 1$ a scan. I have around 1600 B&W photos waiting to be scanned, and quality is deteriorating every year, could probably scan 2-3 at a time at 300dpi. But the sheer number of pictures makes me go weak at the knees."
I've heard that sort of complaint a few times, but now there is RansenScan which automatically extracts multiple photos from a single can.
These photos were taken from my time in Japan in the 1980s and in those days photos were printed quite small so I can now get five photos per scan, and they are extracted automatically.
"But does it straighten them too?"
Yes, RansenScan will straighten photos which have not been placed exactly on the scanner, have a look at the screenshot below:
Even though the the two colored images are "wonky" RansenScan has managed to extract them correctly, see the green arrows below. It has gone a bit gah gah on the black and white photo, but in that case click on the extracted version at the bottom right, and do a manual rotation:
The result is this:
What's more if you already have a Windows compatible scanner you don't need to spend hundreds of dollars on new hardware, RansenScan will do it for less than $50. Which answers the complaint:
"The only reliable way to ensure that all my photograpgs will survive the years is to transform them into digital form and just keep redundant copies somewhere far from my home. But I just can't imagine transforming the mountain of pictures I have 3 at a time on a flatbed and then cropping them into individual files. And I don't want to spend $500 on a new machine just for this job. There HAS to be an inexpensive software package which will help me out here."
RansenScan has a "Save All Sub Images" command where you choose the directory, base name and number to start at.
The Windows demo is free, so you can try it with your own pictures:
