||Top Ten Digital Photography Tips|
|Subject:||Manual whitebalance on color cards & natural elements|
You can print, buy or in another way get hold of some colored cards, preferably light tones, but hard dark ones can create some interesting effects too.
To warm up your picture a bit, set the whitebalance on light blue. To make it redhot, use dark blue.
For black and white to increase contrast? Set it on orange or yellow.
These are only some examples.
