If you need to crop, select the crop tool,
click clear to remove any presets and type in the dimension
of the side to be cropped. When you drag the marque you will
now see the cropped image. (Setting the snap to document bounds
makes this easier. VIEW > SNAP-TO > DOCUMENT BOUNDS.)
Please Note: All monitors show colours slightly
differently. To minimise this problem, set Adobe RGB (1998)
as your RGB working space (EDIT > COLOUR SETTINGS). Also
it is a really good idea to profile your monitor if you have
not already done this - as a minimum use Adobe Gamma (see
your manual). We profile using a Gretag Macbeth Eye-One Display2
colourimeter for neutral monitor colours.
Make any adjustments you want including levels, saturation
and colour balance (its worth remembering that a little saturation
is lost as the image is printed as paper is not as bright
as the screen image. I usually get the image saturation looking
right on screen and then add between +10 and +20 to colour
saturation.)
Finally (and you should always save an unsharpened
version for archiving before you do) - sharpen the image using
your preferred method. I use the unsharp mask filter (as a
start point for moderate sharpening try: amount 225%, radius
0.5, threshold 1). Again add a little more sharpening than
you would for screen viewing - but don't overdo it as oversharp
images do not look natural.
