Guidelines for posting digital pictures
These are guidelines for editing digital images for email, webpages, or PowerPoint presentations. These instructions are for digital images of xrays, but are also generally appropriate for other images.
(1) open the file in any photomanipulation software (some type always
comes with your camera, or use PhotoShop, or any other software)
(2) make sure the pixels per inch are 72 (some cameras save it as
something
else, but most are already at 72)
(3) for xrays, change the image to greyscale (it may not look like it is in color,
because it is a black and white image, but the camera saved it in color)
(4) rotate it so that it is oriented in the way your audience is used to
seeing it
(5) crop it so you only show what you want to show, and always eliminate
the
patient identifiers
(6) resize it so that it is about 4 inches tall (this is the same as 288
pixels tall); this size is great for emails or PowerPoint or web pages. Larger images will not increase the resolution on the monitor or screen.
(7) save it as a jpg, with a medium compression level (about a 5), and
kill
any patient identifier in the filename.
Do not save it as a jpg until the end, otherwise you will lose
resolution.
