    White Balance For An Image - Syed Ibtisam Nafis

    An imaging apparatus which have white balance control means comprising:

    Providing a method of correcting to a white balance (WB) of an image which includes obtaining a first image captured by or photographing a subject when it is flash it emits light, and a second image captured by photographing the subject when the flash emits no light; obtaining a WB gain of the first image and a WB gain of the second image; obtaining a color balance (CB) of flash light, based on at least the one of the obtained WB gains of the first and the second images; and correcting a WB of the First, the image, based on the CB of the flash light.

    An imaging apparatus which have white balance control means comprising.

    1.1 adjusting white balance based on —

    (1) the brightness of a

    photographed object,

    White balance is the adjustment of a digital photograph to make its colors appear more realistic and original. "It’s a way to set a photograph to its neutral appearance, to make the white look the same white, For example, if you take a photo of a white object in certain lighting conditions such as mixing of red, green or other light, it can appear bluer than it actually is in the real life. To counteract this, we can use your camera’s white balance settings to get rid of the blue cast or you can use software such as  post-production, like Adobe Photoshop, to make Color Balance adjustments for its originality.

    ––––––––

    Different lighting situations create different color temperatures in an object during photography.

    It’s called "white balance" but it actually affects all and every colours in our photo. If we are shooting in or with natural light

    from overcast sky, our photos will have a cold color temperature in it, more of blue tone is seen. If we are shooting in an unnatural incandescent light with your typical tungsten light bulbs which creates a warm color cast on it, one shows up as more yellow or an orange. And shooting under certain types of a fluorescent lights can give your photos a green tint. Effect on it.

    ––––––––

    Different color temperatures convey different moods.

    The main goal with the white balance is to understand how it can be affected and how to use it intentionally. Trying a more realistic white and see whether it helps or hinders our image — Sometime we may not always want perfectly accurate colors in our photos. White balance is a great place to start with, says photographer Kenton Waltz. Then you can easily decide how you want it to feel, and how you want it to adjust from there, says Waltz. Then I ask myself, ‘What’s the story these photos are telling and how is that color temperature works and are going to affect that particular story?’

    ––––––––

    Adjusting white balance based on brightness in camera is a good first step all we need to do is to explore customized settings in our camera, manual white balance adjustments are also an option; we can choose a setting depending on our light source.for example, If it’s cloudy, there’s a cloudy day setting in our camera. If you’re shooting in bright sunlight, there’s a setting for that, says Rivera. We can adjust based on where we are at present. But I usually use auto white balance, and then adjust things in editing afterwards.

    Aim for consistent lighting.

    Shooting photos with mismatched sources of light will make it more difficult to edit the white balance in post-production of the photography. We must try to get our light sources to its match, If we have a somebody lit with an incandescent bulb sitting next to a window on overcast day, we are going to have one half of your photo really warm and the other half freezing. So in post it is really hard to fix that circumstances.

    ––––––––

    Sometimes there are situations where a skewed color temperature works in our favor. As for example, say we are shooting in a dimly lit bar or restaurant. That’s the type of thing where we want to convey that mood. You may want to preserve the color of the ambient light which are surrounded rather than correct it, or say you’re shooting a sunset, and an intrinsic part of the picture is in the warm light of the sun. You wouldn’t want to auto correct it, because it would turn everything blue."

    Some photos of a snowed over village being correctly colored.

    Adjusted white balance in editing that photo. Tweakels that color balance of our photos in that post can be as simple as the ant adjusting the very Temperature Slider of or in our Adobe Light room. Just like similar to your camera’s settings, we can also choose there various forms of options in the White Balance (WB) drop-down menu in the Develop panels — Each and every options for various types of lighting conditions — or you can choose to set a customized white balance just by selecting a neutral tone in our image. This is what a test shot with a gray card would come in handy again here, as it would serve a perfect neutral tone. Then we can just copy those edited photos onto the other shots in your set.

    ––––––––

    Use of a Photo Adjustment layer.

    Make a subtle or quick, and easy color adjustments using a Cooling or Warming Filter in it.

    Just by making localized changes with layer masks or by a Gradient Map Adjustment Layer.

    To balance images with the uneven lighting, create a layer mask to our edit only select areas or make tonal shifts on a gradient of our photos.
