white-colour balance

Seems appropriate subject with all this snow around!

Thanks everyone for your lovely welcoming comments. I didn't really believe that anyone would read this.

WHITE COLOUR BALANCE
I didn't know there was such a thing until last week.
But white balance (WB) is the process of removing unrealistic colour casts, so that objects which appear white in person, look white in the photo. Our eyes are very good at judging what is white under different light sources, however digital cameras find this harder.

Normally on the Auto setting my camera does this automatically (very well!), but my first project is to take a few pictures, playing with the white colour balance to affect the colour/mood of the photo.

I have 6 different Auto WB settings on the camera:

Tungsten
Fluorescent
Daylight
Flash
Cloudy
Shade

I took 3 different pictures (nothing special) using all the auto white-colour balance settings on the camera on the same early frosty morning.



I must admit I was quite surprised how much difference there really was. I thought it would take a really well trained eye, to spot the difference, but it is actually quite obvious especially when side by side.


SET 1

I wanted to give the impression of coldness so I wanted to choose a setting that brought out the blue in the picture without making it look too false. I have chosen 41 (worst 38)

42 Flash

41 Fluorescent (first choice)
40 Tungsten
39 Cloudy
38 Shade (worst)
37 Daylight
36 Auto












SET 2 again I wanted the impression of cold so I have chosen 34 (worst 31)

35 Flash
34 Fluorescent (first choice)
33 Tungsten
32 Cloudy
31 Shade (worst)
30 Daylight
29 Auto












SET 3 I wanted a feeling of the warmth of the sunlight in the tree so have chosen 24 (worst 26)

28 Flash



















27 Fluorescent


















26 Tungsten (worst)




















25 Cloudy



















24 Shade (first choice)




















23 Daylight




















22 Auto












That was a lovely easy project to start on.
I have learnt in very simple terms that I might possibly remember..........
.........that using Fluorescent WB gives a cold feel (without making it look too unreal)
and Tungsten WB gives a warm feel.
