Join Ben Long for an in-depth discussion in this video Understanding when a white balance adjustment is applied, part of Exploring Photography: White Balance and Color Temperature.
- So, I keep talking about white balance…being a calibration process.…The camera changing its ideas about color…to compensate for the color of the lighting.…But when does that change actually happen in my image?…That depends on whether you're shooting…in JPEG or RAW format.…If you're shooting in JPEG format,…which is what your camera defaults to…when you take it out of the box,…a lot of things happen inside the camera,…inside its own on-board computer.…So, you go through the process of taking your shot,…you auto-focus, you figure out an exposure,…maybe you make a custom white balance setting or something.…
You take a picture.…That produces a bunch of data on the image sensor.…The camera reads that data off,…and if you're shooting in JPEG mode,…it does a lot of processing to it.…It, first of all, interprets that data…into a color image.…It then looks at the white balance setting…that you specified, and alters the color…to calibrate the color in the image…to the light that you were shooting under.…It then might perform some contrast adjustments,…
In this course, photographer, author, and educator Ben Long explores the art and science of white balance and color temperature. Ben explores how to adjust your camera's white-balance settings, and what to do when auto white balance goes wrong. He then surveys some optional aids for white balance, and scenarios where "inaccurate" color may well be the right stylistic choice.
