Viewing Basics

Here are some things to check before printing:

The correct ink should be in the printer, and enough of each color should remain to finish the print.
The correct paper should be in the printer. It should be the right type for the job, the right size, and right side up.
The correct settings should be chosen. This includes the correct paper size and orientation (landscape or portrait). After these settings are chosen, the image can be previewed, which is a quick way to check for positioning or scaling problems. The correct settings for the paper type and printing speed (high quality vs. low speed) also need to be chosen.
The dpi of the image should be large enough to generate a good print. For photos on high-quality photo paper, 200 - 300 dpi is a common, but more textured matte papers can take a lower dpi. Some printers can print from edge to edge on a piece of paper, but other printers require a margin.

Here are some things to keep in mind when creating web or email images:

Web images should be resized to 72 dpi, downsampled to fit the available space, and compressed to keep the file size as small as possible. JPEG is the file format most commonly used for photos on the web.
Web pages contiaining photo galleries can be made in Photoshop Elements using the Create Web Photo Gallery feature. The folders containing these pages can then be burned to a CD or uploaded to the web.
Emailed files should be especially small to prevent long download times for recipients. Some systems also have a maximum allowable size for email.
The dpi of the image should be large enough to generate a good print. For photos on high-quality photo paper, 200 - 300 dpi is a common, but more textured matte papers can take a lower dpi. Some printers can print from edge to edge on a piece of paper, but other printers require a margin.

Here are some things to keep in mind when archiving and cataloging images:

Generally, the most convenient way to archive photos is to burn the originals and final images to CD-R.
The contents of the CD can be tracked by cataloging the images or making a printed reference sheet via Photoshop Elements' Contact Sheet feature.
To prevent loss in case of a disaster, often two or more CDs are made and stored in separate locations such as a safety deposit box and a fireproof safe.
Cataloging files makes them easier to find and allows the photographer to easily view many images at once, regardless of where the images are stored on the computer.
