Custom White Balance for Colour Accuracy
Previously I discussed the Auto White Balance and Presets. Generally speaking, auto white balance works very well in most newer digital cameras. When there is only one light source, or If you are doing some candid shots just for fun, you don’t need to be too concerned about Custom White Balance. However, if you take pictures and colours must be accurate, it is your best option. Also, if you want to simplify your editing process, you should consider switching to Custom White Balance.
What is Custom White balance?
A digital camera needs to have reference of a Neutral Grey colour to refer to and then it can adjust the other colour accordingly. Basically, we need to register a neutral grey colour for our cameras under the light condition that we take photos. When the reference grey colour is registered properly, the cameras processor will adjust the other colours automatically. Here are some examples:[/vc_column_text][vc_single_image image=”22432″ img_size=”600×400″ add_caption=”yes” alignment=”center” style=”vc_box_rounded” onclick=”link_image” css_animation=”fadeInUpBig” title=”Auto White Balance”][vc_column_text]There is a heavy yellow colour cast in above image. There were two light sources in the scenee, the sky light and the fluorescent light from the building. The combination of two different light sources confused the camera. Therefore, the auto white balance could not make the correct colour rendition.
For the next shot, I set the custom white balance by using a grey card. Therefore, the camera had a reference to refer to and set other colours. Below is the result.[/vc_column_text][vc_single_image image=”22433″ img_size=”600×400″ add_caption=”yes” alignment=”center” style=”vc_box_rounded” onclick=”link_image” css_animation=”fadeInUpBig” title=”Custom White Balance”][vc_column_text]The colours are noticeably more accurate in above photo. There is no colour cast in this image. Setting up the custom white balance can take a little time but saves you lots of post processing work.
Rules Of Thumbs for using Custom White Balance
As a rule of thumb:
– when there are multiple sources of light (more than one) you need to tell the camera what to do about colour.
- whenever you take pictures indoors, using Custom White Balance will provide the truest colour for you.
- When taking photos in Shade/Shadow. The light temperature varies from location to location and cameras usually don’t have the data to adjust for these situations.
- When you take pictures in a very colourful environment. You need to help the camera see past these colours and understands the neutral colour.
