Apple QuickTake 150 (for Windows) - Manual (Page 41)

Changing the bit depth of an image
You may want to change the image bit depth of an image you take. For
example, if the image uses millions of colors, but you plan to print it on a
grayscale printer, you can change the image bit depth to 256 shades of gray.
Changing image bit depth and compression scheme can reduce the amount
of disk space required to store an image, but the changes may affect
image quality.
To change the image bit depth, choose Change Image Depth from the Image
menu. Then choose the image bit depth you want. If you’re not happy with
the result, choose Undo from the Edit menu.
Adjusting the brightness of an image
If you take an image that seems too light or too dark, you can adjust its
brightness using the QuickTake program. Note that this procedure only works
with 24 bit color (16 million colors) images.
1 Open the image you want to work with.
2 From the Image menu, choose Adjust Brightness. In the submenu that appears, choose
either Lighter or Darker.
The image is lightened or darkened accordingly. If you’re not happy with the
result, choose Undo from the Edit menu. You can apply the Lighter and
Darker commands several times until the image has the appearance you want.
Adjusting an image taken under fluorescent light
Fluorescent lighting causes all photographs, even those taken by regular
cameras, to take on a green tint. You can use the QuickTake program to
correct an image captured under fluorescent light. Note that this procedure
only works with 24 bit color (16 million colors) images.
1 Open the image you want to work with.
2 From the Image menu, choose Adjust for Fluorescent Light.
The image is corrected. If you’re not happy with the result, choose Undo from
the Edit menu.
