How Do You Superimpose Coin Photos For Die Clashes?

You can do it in the free app Photoshop Mix.
Find two coin pictures of similar lighting and toning, then click on the layer and change the opacity slider.

Edit: here's one I did in 3 minutes. (2 minutes to find a suitable picture & 1 minute to do the 'shopping.)
Edit 2: 100% opacity on the base image, between 30 and 40% on the top image.

Well, now that I have that app for troubleshooting purposes I'll have to try it. I used Photoblend before.

The overlays on maddieclashes are great except when you want to use your own pics.

I use Paint.net. Over on LCF I gave step by step instructions on how to do an overlay using Paint.net. Take a look here:

I rarely do an overlay that is not animated. I find the animation helps tremendously to see things like clashes. Take a look here to see a few I've done:

If anyone is interested I can explain how to do these. They are actually very simple.

edited to add:

The 1955-S animation shows why you may need to do these yourself, with images of your own coin. In this case the reverse is slightly rotated, so the standard, perfectly-aligned reference overlays won't show the clash marks in their correct positions.

Also, the animated overlay allows you to see exactly which features were clashed, and to what extent. When a fixed overlay is done, the secondary image interferes with your ability to carefully examine the clash marks, as they are obscured by the secondary image. With the animation, you can see both. Look at the 2014 dime clash to see what I mean. This clash shows up on both sides, but you can only really tell where the damage is done by looking at one side at a time. The animation enables this for both sides, while giving reference to the other side as it transitions. Single-image overlays can't do this.

This may seem a little unorthodox and slightly odd but I suppose many of us are. I superimpose images of ancient Egyptian art for certain reasons and you could easily do something the way I do. Get the photo you like and go have it copied on transparency paper. Superimpose it but make sure that you get a copy of its own "mirrored" image. This way if things are not lining up correctly you may discovered that your imagining things backward.
