Droste Effect Tutorial
***NOTE***
While this tutorial still works if you use the versions of the programs that are mentioned, it is now much easier to do in Photoshop with the Pixel Bender Droste effect plugin.

Here is a tutorial on how to do the droste effect using Mathmap- For Windows (also works for Linux and even Mac, but this tutorial specifically for Windows users).

This is an advanced tutorial. You need to be very comfortable with Photoshop and/or GIMP to be able to follow this tutorial. If you don't already know how to create layer masks or crop an image, learn how to do those things first before you try to follow this tutorial because this tutorial does not teach you how to do those things, but requires that you be able to do them.

IMPORTANT: This tutorial will ONLY work with mathmap version 1.0.1, which is the version linked to above, and you must carefully follow the following installation instructions for it to work.

You can download all the source code and images HERE (~3megs).

You can download the GIMP and GTK for windows Here.

You can download mathmap for GIMP on windows HERE.

Mathmap install instructions:
1) Unzip it.
2) Copy mathmap.exe, libgsl.dll, libgslcblas.dll into the gimp plugin directory. On my system it is here:
C:\Program Files\GIMP-2.0\lib\gimp\2.0\plug-ins
3) Copy mathmaprc and new_template.c into a new directory named:
C:\Documents and Settings\ "your-user-name" \.gimp-2.2\mathmap.

NOTICE THERE IS A DOT (".") before gimp-2.2 in the above path.

*****IMPORTANT*********
If your computer is in any language other than english, there are steps you must take to get Mathmap to work correctly, involving setting the decimal point in regional settings. Click here for an explanation: Mathmap and Foreign Language Packs

Enjoy, I hope you find this to be educational and helpful.

If you use the tutorial and produce an image, you should submit it to the Escher's Droste Print Galley group. A link to this tutorial or to my stream from your first droste effect image would be appreciated. I am sharing this technique freely, but it bums me out when someone uses the tutorial and the code and doesn't give some kind of credit or thanks.

Thanks,
Josh
