This is the second of my "Tips from the Top". As a free bonus, there are five tips for the price of one.
These are from Vincent Versace. They appeared in an interview article in What Digital Camera? (June, 2003):
Sharpening: We all know the conventional wisdom is sharpen last. VV also points out that digital images may be sharpened three times and that different techniques are suited to different subjects. Unfortunately, he doesn't elaborate, except to say he uses nik Sharpener Pro!
Shoot raw format. Leave the processing to the PC.
Save time: learn keyboard commands and shortcuts. Use a graphics tablet.
"... digital photography is about creating a sense of hyper-reality rather than surreality". The subtext in this tip is: don't mess with the filters menu too much.
Use Adobe RGB rather than sRGB, if you have the choice.
