Now that your anaglyph is done, you should save it. Always
keep a Photoshop-format file so that you can always revert
back to it for any adjustments you'd like to make later.
But Photoshop-format files cannot be viewed in Web browsers
and are massive files, due to the large amount of information
they need to store.
Keep the image at a high level of quality so that
the color balance needed for the 3D illusion is not
destroyed. In general, do not save
below 50% quality (JPEG quality setting 6 in Photoshop).
To prepare an image for saving this way:
- Select Flatten from the Layers palette context menu.
The layers are merged into one single layer, and extraneous
channels are removed. (Check the Channels palette
to make sure you only have RGB, Red, Blue, and Green
listed. Delete any extras.)
- If you are saving as a JPEG, the image can be left
in RGB color. If you are saving as a GIF select Indexed
Color from the Mode submenu of the Image menu. Convert
the image to Indexed Color and use an Adaptive palette.
- Open the Save dialog box and choose the proper file
type (they are mutually exclusive, so at this point
only one or the other can be selected.)
- Give the file a name and save it. It's now ready
for Web posting.
