Here is my Photoshop technique for identifying varieties

A couple of board members here asked me about overlays I have used as an aid in attributing varieties.
If any points need further explanation, just ask.

First thing is to capture the images that you're interested in. If the site you are on doesn't allow the "Copy" function, capture the whole page with the "Prt Scr" (Print Screen) key. In Photoshop, create a "New" file about 8 x 10" then paste it into Photoshop. It should look something like this.

Next, use the circle key to capture the subject coin by using either "Copy" or "Cut". Now go over to your "Layers" menu and right click on the layer and delete it, then paste the coin (which you just cut out or copied) in the remaining layer. Now it should look something like this.

Now head on over to where ever it is that has a reference image you want to compare. In the case of Half Dimes, it's here: http://rob.com/russ/collection/ Find the image of the coin that you want to use to compare with the subject coin. Copy it and paste to Photoshop. It should look something like this.

Next, using the circle tool again, cut or copy the coin, delete the layer, and paste it. Now it should look something like this.

Now, re-size the larger image to match size wise with the smaller image. At this point, one image will stay the way it is, that should be the image on the "bottom" of the layer. Now, the image on top needs to be moved partially over the bottom image. With the top layer in place, go to the bottom right hand corner of Photoshop and click on the effects button. It is the one labeled FX (in italics), a pop up menu will show "Blending Options", click it and another menu pops up showing General Blending. Under the heading of General Blending you will see "Opacity 100%" highlighted. Move the slider to about 40% and it should now look something like this.

Now slide the top image completely over the bottom image. At this point you will be making adjustment after adjustment, including rotating, stretching, shrinking and readjusting the blending as needed. But in the end, hopefully it will look like a dead on match like this.

And that my friends is how it's done.
