Electronic presentation of images requires somewhat different preparation than for printing. This article recommends a process that has proven satisfactory to the author. Other methods may be equally valid, and the “best method” will continue to evolve as technology changes. This article assumes Photoshop CS on Windows, but other image processing software can be used to implement the same method. Although much of the discussion assumes you are preparing images for digital projection, the same methods generally apply to preparing images for display on computer monitors or even televisions.

There are many variables in the world of electronic imaging, but here’s the bottom line: your photos will look their best if you use professional photo editing software to (A) re-size them, (B) convert the color, and (C) sharpen them. Let’s look at two different applications of your images.
1. Projection on the high-resolution Canon SX-50 Realis Digital Projector, as used by NBCC for Electronic Image Competition. Size each image to fit within the projector native resolution of 1400 by 1050 pixels. Convert your colors to the sRGB color space. Display the image full size (100% zoom) on your monitor and sharpen to taste.
2. Electronic Slide Shows for Friends and Family. Size each image to fit within a typical desktop computer resolution of 1024 by 768 pixels. Convert your colors to the sRGB color space. Display the image full size (100% zoom) on your monitor and sharpen to taste.
Of course, this summary omits the details and other options. For more, read on.
