How to Prepare Digital Images for Projection Using Photoshop

The Club's digital projector only outputs 1024x768 pixels to the screen. These guidelines will help make your digital images look their best for projection. They are written for Adobe Photoshop, but Elements users will find them useful, too.

Pixel Dimensions are the important values when it comes to digital projection, but people are always concerned about the "pixels per inch" resolution value. The resolution setting controls how an inkjet printer is going to spray ink on a piece of paper. Varying the spacing of the ink droplets will change the size of a final print on a piece of paper. Spread the pixels farther apart, the print gets bigger. Bring them closer together, the print gets smaller. But we do not have any variability when it comes to digital projection. The club's projector has exactly 1024 pixels across by 768 pixels down. That's all there are. No more. No less. They don't move.  So as long as the Pixel Dimension of your image is about 1024x768 you can set the resolution to any value you like. Most people use 72 dpi, but it really has no effect on how the image is projected because you can't change the spacing between the pixels on the screen.

After making these adjustments, save your image as a High-Quality jpeg.
