Preparing Images for Digital Projection.

The typical digital projector used for projecting images has a XGA resolution of 1024 x 768 pixels. Digital images or Scanned images for projection should be submitted in this size for the best reproduction.  In the event the projector you are using is capable of higher resolutions, you may still use this process to resize your images by using the pixel resolution of your digital projector.  Please note that the image size in inches, is not important for digital projection.

Capturing the digital picture should be done at the highest possible resolution of your camera.  For digital projection you will need to crop/resize this image to fit the following:

Height not to exceed 768 pixels

Width not to exceed 1024 pixels

These sizes also apply if you are scanning slides or negatives.
