I am trying to learn how to do picture overlays. (not sure that is the right term) I want to be able to put one picture on top of another to compare them. Somehow where one is outlined in one color and the other has a different color?
Does anyone know how to do this?

I want to learn how also, for die clashes.  |

Do either of you have Photoshop? That's by far the optimum tool to use because of its layering capabilities. There's a bit of steep learning curve on that software, but I think it's worth the effort.  Coop might drop by and suggest his methods, which I deem to be better-developed than my own. The overlays I do are a combination of photos and outlines to confirm positions of overdates, such as below. Here I use two programs--Adobe Photoshop and Illustrator, which I find gives clearer results--but is a little more work.  |

I've never done before but it looks like a basic overlay is easy to do provided you've got pics of the obv and rev of exactly the same size. Apart from that problem, is this done correct?  Edited by DL20K

DL, That looks like a nice example to me. I imagine that one's used to predict the position of a die clash?  |

Yup, that was supposed to be one of those.
It's been done like this:
- Get pictures of obverse and reverse,
- Flip the reverse in the correct position*,
- Open Photoshop / Gimp,
- Open the obverse file in PS / G,
- Add new layer of the same size as the picture of the obverse,
- Copy and paste the reverse in the new layer,
- Lower the opacity of both layers (it's 69% here),
- Move one of the layers if it's not in precisely the right place, so that the rims are exactly one over the other.
* I use Irfan View for the simple things, of course you can flip the photo later on in PS / G.

GIMP is free, Photoshop will eat into your coin budget!  GIMP is available for Windows, but I use it on my Linux system. GIMP is included with many of the linux distros, like Ubuntu (also free). |

* PS does seem to run better on XP than Gimp.
* From what I've heard, most agree that PS is easier to use than Gimp.

I would have to agree with both of those comments. I had some issues with GIMP when I installed it on Windows 2000 a few years back, but according to the support forum discussions, the problems were related to my (older) ATI video card. I did install it on another machine (nVidia video) with better results. That said, GIMP on my Linux system is rather nice; ATI video and all! Edited by jbuck

I believe coop uses ver 5.5. He has been using it for about ten years, and is quite capable. You have seen some of his work on this, and other forums. I had ver 4.0, but it wouldn't setup, so my "guru", wsent me a copy of 7.0. I have used it a bit, but it is hard, (for me) to get a hold of, unless one uses it constantly. I wanted to make the overlays for determining clash remnant sources, on Canadian coins.
