Digital Image Basics for non-Photographers • Blaise Tobia
A Powerpoint slide is 1024x768 pixels, which is equivalent to the number of display pixels in an XGA monitor or projector.
If you are being asked to submit your images within a Powerpoint presentation, then 1024x768 is ideal.
Each image will completely fill a Powerpoint slide with no wasted data.
Even if you are submitting individual images rather than a Powerpoint, 1024x768 is a good image size,
especially when there won't be any zooming-in (which is ususually the case in jurying or interviewing).
Exceptions would be where larger image sizes are allowed (such as CAFE's 1920x1920 pixels)
or if you have mostly or all vertical-format images.
(See the previous page for a discussion of horizontal/vertical format images.)
Images can be imported into a Powerpoint presentation in many file formats.
Be aware that if you bring them in as uncompressed files (such as TIFF)
the file size of the Powerpoint presentation will be much larger
than if you bring them in as compressed files (such as JPEG).
The images are embedded as, in effect, sub-files in the Powerpoint presentation file (.pptx)
maintaining their file-format chracteristics and size.
If you put an image into a Powerpoint presentation larger than the Powerpoint slide size (1024x768)
it will scale the image down for viewing but not its embedded file size,
so the Powerpoin presentation's file size will be unnecessarily large.
