* Stitching photos

[TimM]

I’ve got a number of large family trees drawn on A0 sheets which I have photographed in A3 chunks. I’d like to stitch these all together. I’ve got a couple of graphics /photo programmes with stitching tools, but they don’t make any provision for slight differences in scale or orientation.
Can anyone recommend a software tool that can do this?

Thanks

The only program I know which seems to cope reasonably well in Photoshop elements.

To be honest I have never had much luck stiching documents with more than a couple of images, and I took them with a tripod and moved the document and not the camera so they were at the same position/magnification, scanned ones are not too bad and elements makes a good job, you just need lots of memory on the computer and a fast PC.

Photoshop, either Elements or the full version,  bring in your new picture as a layer and adjust the opacity so that you can see the layer underneath that you are trying to align to.  Concentrate on the join and enlarge the image so that you get a good view of this. Use the Free Transform tool to adjust the new document so that it aligns with the version underneath.  This works around the middle of the image so you need to align the middle of the documents first and then transform. Digital cameras tend to suffer from barrel distortion at the edge of the picture, particularly at wide angle, so it is necessary to take plenty of pictures to allow a good overlap that avoids the edges.  I have used this method for photographs and also documents that are too big to be scanned in one go.  Some patience required at first but you soon get the hang of it.
