Title: Tutorial on stitching mult-part scans together
Post by: ChadTower on February 13, 2008, 04:27:31 pm

I poked around today looking for one and came across this (http://emptyeasel.com/2007/05/11/scanning-large-artwork-how-to-stitch-the-pieces-back-together-in-photoshop/).  Perfect for sideart or a playfield.

Why doesn't he simply use the Photoshop stitching tool? At the very least create the layers with it.

Using the "difference" blending mode in photoshop really helps in lining two separate images up properly.

Is that all that different from manually managing opacity as you line layers up?  I am not familiar with that action in Photoshop.

when you use difference on two overlapping layers anything that is not the same(different) will show up as a mix of white and black shapes, when it is perfectly lined up the area overlap will be a black stripe.

not too much different from opacity, might make it easier to get it exact though, or make it easier to spot incongruities in the two scans...

edit: found an example

Oh nice.  The rotating bit is the part I fear most - obviously you don't want to rotate many times.

if you are scanning then i imagine rotating wouldn't be too much of a factor, and it could just be rescanned.

Yeah.  I figure the odds of getting every image of a full playfield lined up perfectly are pretty low.  There will end up being a little bit of rotation no matter what.
