Scanning long or tall photos
|Top Previous Next|
In order to recognise and extract photos on the scanner you have to give RansenScan a few hints. This is done in the Automatic Recognition Dialog. The aspect ratio is a measure of how long or tall a photo is. When you are scanning long photos (or tall ones) you need to set a high Max Aspect ratio. Here's a scan with a long photo (top left):
To make sure RansenScan can get that you need to set the max aspect ratio to as shown below, I've set it to just over 3:
The photos on the scan bed have a problem though, in the scan the oval portrait is too close to the edge and it needs to be moved away from the edge of the scanner:
So this solves both problems of the original scan.
