Custom White Balance (Photography in 90 Seconds)

I've written a new eBook called "A Concise Introduction to Photography": ethanwilding.com Custom White Balance is the process of setting the neutral gray reference point manually, rather than relying on your camera's Auto White balance (which typically only approximates neutral grey.) Custom WB is an important step for anyone who is serious about achieving accurate colours in their images. If you are shooting RAW single images, then you can just take a picture of a spectrally neutral grey card and set the WB in post-processing. However, if you are shooting JPEG or Video, it is important that you set the custom WB in your camera before shooting. How you do this is dependent on your particular camera, but it will involve taking a picture of the gray card (fill the frame as much as you can) and then telling the camera (via its menu system) to use that image as the neutral reference point. You will have to read your camera's instruction manual for the particular details of those simple steps. Now, once you have the Custom WB set, you will likely have to manually rotate the WB dial or indicator from AutoWB to Custom WB. (Again, the specifics will vary for each camera manufacturer. Once you have that stuff set, you are good to go shoot your videos without having to worry about trying to do onerous colour correction in post-processing. Good luck!
