Saving |
|
| |
| You can use Photoshop
to save files in a number of different formats. In addition to Photoshop
format (*.psd), you'll need to be familiar with TIFFs (*.tif), JPEGs
(*.jpg), and GIFs (*.gif). |
| TIFFs
are files that are very rich in data (color, resolution, etc.).
Many scanners automatically save scans as TIFFs. |
| |
| JPEGs
are a step below TIFFs in "richness." They are commonly used
on the Web and are good for saving images
in which differences in color and brightness between adjacent pixels
is slight. To save a Photoshop document as a JPEG, do the following: |
- choose File>Save As.
- In the Save dialogue box, name your image and be sure to select
the JPEG option from the menu just below the filename (you CAN
NOT simply type ".jpg" after the file name!).
- When you click Save, one more dialogue box appears: JPEG Options.
For the Quality option, it's a good idea to choose anything "5"
and above.
- Click OK to finish.

| GIFs are used
mainly for Web graphics and clip art and are better than JPEGs for high-contrast
images. To save an image as a GIF, do the following: |
- choose File>Save As.
- In the Save dialogue box, name your image and be sure to select
the GIF option from the menu just below the filename (you CAN
NOT simply type ".gif" after the file name!).
- The box will tell you that it must be saved as a copy because it needs to change some settings. Choose OK.
- You will be asked to flatten the layers. Choose OK.
- The next dialogue box gives you a variety of options. It's often a good idea to accept the options Photoshop gives you; if you choose not to, the following settings will generally give you the highest-quality (and largest!) image possible:
- Palette = Local (Adaptive)
- Colors = 256
- Dither = None
- Click OK.
- In the GIF Options box, choose either Normal or Interlaced (an
interlaced image is one that gradually appears in a user's Web
browser as it loads; a normal image remains blank until all of
it is downloaded).
