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 file.
               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.

           7.  With the Resample option checked in the Image Size dialog box, change
              the Resolution field to 72.
               When the Resample option is
               checked, changing the resolution
               does not affect the file’s physical
               size; rather, the actual number of
               pixels is reduced. In this case, at
               72 ppi, only 630  810 pixels are
               required for a file that is 8.75 
               11.25.

           8.  Click OK to finalize the change.
