There are many ways to adjust white balance. From adjusting it in camera, using a grey card, or adjusting it in post, it really depends on the situation you are in and your personal preference. Personally, I always shoot RAW and keep the white balance setting on my camera on auto almost all of the time. This way, I don’t have to fiddle with it in camera and the camera gets it right most of the time. If by some chance the camera does get it wrong, I will take it off the auto setting and find the setting that works best for the light that I am it, but still knowing that because I am shooting RAW, I can always make the adjustments in Lightroom or camera RAW.
Interestingly enough, if Lightroom isn’t your thing or your having trouble getting an accurate white balance here is a trick for adjusting the white balance in Photoshop. According to the tutorial you can create an accurate white balance by sampling in the midtones, using a grey point. Create a new layer, and fill with 50% grey, set the blending mode to difference. Next, create a threshold adjustment layer and drag the slider to the left until you see just a few areas that are highlighted in black. Select the color sample tool and click the of one of the black areas that you remember was grey and also directly lit (this is closest to 50% grey). Then hide the grey and threshold layers and select a curves adjustment layer. Using the grey point sample tool, (in the middle) click on the sample point from earlier. This should create an accurate white balance. Finally, remove your original saved sample point and feast your eyes on white balance perfection.
Personally, I think there are easier ways to get the white balance you are looking for but I will give it a try. What are your favorite ways to achieve white balance perfection? Feel free to let us know your process in the comments below.
