Applying White Balance
what happens to a piece of metal when you heat it up as well as getting hot, it also changes color. First of all, it goes red as in red hot. Then it goes orange, then yellow, then white is white hot. After that, it starts to melt. If you leave it in the fire. If you take it out and it starts to cool down, it does the same color change, but in reverse. Now what does this got to do with photography? Well, exactly the same thing happens to the color of light as the sun rises during the course of the day. So it's sunrise first thing in the morning. The light is very red. About an hour after sunrise, it goes an orange, which is that golden hour that we often talk about things like landscape photography, and it goes yellow sort of mid. Morning on by. Noon is gone to a very neutral white light. Now, as human beings, we don't see these changes in color temperature because our brain is fitted with a white balance control and the purpose of that white balance controlling the brain is to filter o...
ut all of the color casts created by the different times of the day. The different environments, even the different sources of light so that we see all light is neutral white light. Your camera, on the other hand, will pick up these color casts unless you do something about it and there is a control in the camera to help you do that. And that control is called the white balance Control. Do you remember these? These are color correction filters, which are commonly referred to his warming and calling filters. And orange warming filter absorbs blue light, and a blue calling filter absorbs red light. There used either neutralized color casts or, more creatively to add or enhance color casts. Now you can think of the white man. It's controlling your cameras, doing exactly the same thing just digitally. If you go to the white balance control, you'll find a set of icons on the exact number and type will depend on your camera, but they're a six. Common wants sunlight, which is sometimes called daylight, flash cloudy shade, fluorescent and tungsten, which is sometimes referred to his incandescent. And these icons represent preset white balance values that correspond to different environmental conditions. or sources of light in order to get rid of color casts or you have to do is juicy, appropriate icon for the conditions you're in on an overcast day. All of this cloud cover is absorbing red light waves, and that's going to create a blue color caste. Now, even though is daylight. If I was to photograph this scene on daylight white balance, I'm going to see that color cast in the photograph. But by switching to cloudy white balance and matching white buns with the environmental conditions, I can neutralize the color cast for much more natural looking image. And the same applies for all of the other white balance setting. So if my subject is in deep shade, if I switch to shade, I'll get a neutral image. If I'm using flash, if I switch to flash, I'll get a neutral looking image. The same applies to artificial light sources. Artificial light, such as those found in a photographic studio, have different color temperatures. Elektronik Flash, for example, is very soon with daylight, but a tungsten studio lamp would have a very red or orangey color caste on Justus White. Balance allows me to compensate for the different color temperatures caused by the weather. It also allows me to compensate for the different color temperatures of different light sources. So the number one reason for white balance is to get rid of unwanted color casts caused by environmental conditions or by different sources of light. No.
