Apple Macintosh PhotoFlash - Manual (Page 99)

3 Adjust the Size and Sensitivity settings as necessary, then click OK.
Try fairly low settings first, increasing them only if the dust doesn’t disappear
when you click the selection. To see the effects different settings have, use the
Remove Dust command as described in the previous section.
4 If it’s not already selected, click the DeDust tool in the Tool palette to select it.
The DeDust tool becomes highlighted when it’s selected.
5 Position the pointer over the part of the image you selected.
The pointer changes to the DeDust icon.
6 Click anywhere in the selected area.
PhotoFlash attempts to remove dust from the selected area. If you have
trouble removing dust with the DeDust tool, you may find it easier to use the
Remove Dust command as described in the previous section. The Remove
Dust command allows you to preview part of an image while you adjust the
Remove Dust Options dialog box.
Removing scratches
You can use either the Remove Scratch command or the DeScratch tool to
remove scratches from a selected area or an entire image. Both methods work
best if you carefully select the scratch you want to remove, including as little
of the rest of the image as possible. Otherwise, PhotoFlash may interpret part
of the image itself as a scratch and remove details you don’t want removed. If
you find you don’t get good results after selecting a scratch with the Marquee
tool, try the Lasso tool.
The Remove Scratch command allows you to preview its changes before you
make them, which can be helpful when you’re trying to find the right settings
to remove a scratch that blends in with the background. It’s not a good idea to
use the Remove Scratch command to remove scratches from multiple images
represented by selected thumbnails, because the command ignores selections
and instead acts on the whole image.
