Super Slides

What are Super Slides?

Super Slides, also known as 46mm slides, are exactly what the name says. They are medium format film, trimmed to approximately 1-3/4 inches square, and mounted in a special 2" x 2" mount. Super Slides will not be accepted for submission to art shows or college applications.

The primary purposes are either for large display projections or, more commonly, for use with special background projection systems such as Virtual Backgrounds. Because the diagonal of the image is larger than a standard 35mm slide some projectors will cause vignetting at the corners.

Our Process


Alto with 645 option

Your files are scaled and imaged on Fuji Provia 100F RDPIII film at high resolution using one of our Agfa Alto Film recorders like the one pictured here with a 645 option mounted.

We constantly monitor the process and film emulsions to maintain the most accurate color balance possible. Your Images should be in either Adobe 1998, or sRGB color space for an accurate match.



In 2010 GEPE abruptly stopped producing mounts. We have been able to find mounts from time to time, and have a small stock of anti-newton glass mounts. We will continue to offer mounting until we run out of mounts.

For a few years we did make our own mounts from two pieces of optical quality.8mm laser cut cell cast anti- newton acrylic with hardened surfaces to minimize wear. This was an expensive process, and we do not plan to revive the process.

Preparing Images for Super Slides

We recommend that your images be at least 1800 x 1800 pixels, but this is not critical. You can send smaller size images but sharpness may be lost. In many cases this is not important for background images, but it's better to have a sharp image and defocus it.

The optimal image size is 2,750 x 2,750 pixels, this is the actual size recorded to film. Smaller images are scaled up to this dimension. Because of the mounts we produce, none of the image will be cropped by the mount.

If your image is square it will fit full frame. Images that are not square will have black at the sides or top & bottom of the image.

Your Images should be in either Adobe 1998, or sRGB color space for an accurate match. For Virtual Background images you will probably need to add Red to the image to compensate for lighting differences, but the amount may vary depending on your specific studio setting.

We accept just about any format for recording. You can check supported formats on our Format Page.

Virtual Background Test Preview Program

Test your background image files before you order film!

overall view

Our test software lets you test your background first. Create your image, load it up, zoom, move, rotate, put in a subject, adjust the camera position, and check the perspective.

The program will work with the latest versions of Google Chrome, Fire Fox, Safari and Opera. Google Chrome is recommended. (sorry, Microsoft Internet Explorer will not work).

The program can be purchased for only $34.95, and is delivered on CD-ROM. The price includes a $10 credit on your next purchase of Super Slides or 35mm slides.


Simply copy the contents to your disk, place your test files in the test folder and load them up. Make any necessary changes before you commit to paying for film. You can even switch between 35mm and Super Slide format.

Check the stock image page for more information and a link to the on line demo.
