Band of Colorful Moon

These shots were taken during bright full moon day of Raksha bandhan. Just casual shot. After noticing the moon, I was tempted to grab some pictures of the bright shining energitic moon. Consequently pulled my camera, mounted the tele lens and started snapping the moon. What are those colors then? They were taken with varying white balances ;-). That creamed moon with vivid colors ;-). My primary intention was to learn how white balances work. I am still amateur photographer and needs lot of practice to strengthen my skills. This is one such practice carried out to learn a concept. Hope you enjoyed the picture. You can additionaly splice moons with a string to transform it to rakhi ;-).

The colors represent daylight, shadow, tungsten and cloudy white balances correspondingly. So what is WB? It is amount of color temperature shift required to retain white object as white in picture :-). What is color temperature? Back to physics :-). It is the color emitted by black body at particular temperature. If you recall concept of black body radiation, more the temperature, higher is the frequency emitted by the body [how? please read Neil Bohr's atomic model ;-)]. So at high temperature, the color is violet while at lower ones its red (visible range). Similarly when you increase color temperature of picture, the photo turns violet and red as you lower it. White Balance is amount of shift involved in balancing the color temperature. So lower the white balance, more bluish the color while red on other side of temperature. Both WB and CT are measured in in Kelvin
