The SP-800UZ has AUTO White Balance, so why is it necessary to have white balance presets?

Having white balance presets grants the photographer more creative control. For one thing, daylight can be warm or cold. On a sunny day, early and late light has a warmer appearance than when the sun is high.

The WB AUTO White Balance option might color correct for that warmth, thus taking away the ambience. Using the Sunny day setting will preserve that warmth. The WB AUTO setting will also tend to diminish the red, yellow and orange colors in a sunset, so it is advisable to use the Sunny day setting when shooting sunsets.

On cloudy days, the light seems colder because the clouds absorb the warmer red and yellow frequencies of the sunlight coming from above the clouds. Therefore, there is a Cloudy day setting in the presets to record the images with a warmer appearance. Creatively, the Cloudy day preset can be used on a sunny day to give images a more golden appearance, or it can be used to make a sunset appear warmer.

The Tungsten light setting compensates for the yellowish color ... more.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
