Photo Handling 379

You can click the SETTINGS button on this dialog, if you want to change any settings such
as the image format used for the optimization, JPEG quality, etc.

You can change the resolution used in this dialog, by either choosing the physical size
you want for the optimized image (width/height in pixels), or by entering a different dpi
(eg. perhaps 150dpi if you want print quality).

If you choose the dpi option the value you enter is remembered and becomes the default
just for the current session. You can also maintain the photo's current resolution by
choosing CURRENT from the PPI list.

You can also choose to optimize as a PNG (produces much larger images, but better
quality for graphics and text images) or change the quality used for JPEG optimization
(higher quality means larger JPEG sizes).

If your photo is cropped, only the visible part of the image is preserved in the optimized
image.

For printing, a photo resolution of 150dpi gives very good results, whilst 300 dpi will
provide the highest quality commercial printing (most people cannot tell the difference
between 150dpi and 300dpi, but the 300dpi requires four times as much memory or file
space).

Warning: "OPTIMIZE PHOTO" is a "destructive" operation. When you save the file the parts
of the image removed are lost, and the resolution changed permanently (you can of
course undo the changes while the file is open for editing).

You can optimize multiple photos at once if you want them to all have the same dpi.
Select the photos you want to optimize and then choose the OPTIMIZE operation as
described above. If your photos have different dimensions, the option to optimize by
pixel size is disabled and you must just choose the required dpi.
