Day 3 : White Balance

One of the final checks is white balance. The contact sheet shows all 8 default settings on the camera.

White Balance

As you can see by the numbering, photoshop can sometimes do strange things to contact sheets :) So I'll set up the data by photo number from 1-8.

1: Automatic - 4000 temp
2: Incandescent - 2950
3: Florescent - 3950
4: Sunlight - 5000
5: Flash - 6150
6: Cloudy - 5700
7: Shade - 7300
8: K (5000) - 4800

The setup was on a desk next to a large window with a single florescent tube overhead. The sheet in front of the items is a neutral gray/white card.

There is a table in the manual that gives the values for the average value. It roughly corresponds to the measurements above. Although it looks like I'm about 200 off. Still, it's in the acceptable range. I mat try fine tuning under the lamps I have. But that will be for another day. I think it's cool to be able to correct the color setting in the camera.
