3. Choose JPEG in the Format/Save as Type menu. Change the fi le name to
aftermath-web.jpg, and then click Save.
JPEG files do not
support multiple layers.
When you choose the
JPEG format, the Layers
option is automatically
unchecked, and the
As a Copy option is
automatically activated.
3. In the JPEG Options dialog box, choose High in the Quality menu and
then click OK.
You can use these options to reduce the weight of the
resulting JPEG file. Keep in mind that JPEG is a lossy
compression scheme, so the application throws away what
it perceives as redundant data to reduce the file weight.
Lower quality settings mean more compression and
smaller file weight (and thus, shorter download time), but
you might notice significant deterioration in image quality.
The right side of the dialog box shows the estimated file size — in this case, just over
1 megabyte.
4. Close the aftermath.psd fi le.
Remember, when the As a Copy option is checked, the file you had open before the
save remains active in the document window. You need to manually open the JPEG
file so you can make the necessary changes for web distribution.
5. Open aftermath-web.jpg from your WIP>Movie folder.
6. Choose Image>Image Size.
You created this file at 300 pixels
per inch, which is appropriate for
commercial print requirements.
For web distribution, however,
300 ppi is far more than you need.
To further reduce the file weight
and resulting download time, you
should downsample the file to
72 ppi — an appropriate resolution for most web display requirements.
