Custom White Balance under Mixed Lighting: Taking the Sony α6700 as an Example
Explain the manual use of custom white balance on the Sony α6700 under various ambient lighting conditions, the white point sampling steps, flash conditions, and collection tips; it does not promise neutrality, skin tone, or frame-to-frame consistency after calibration, nor does it claim that an 18% gray card reflectance is required for this model.
You can try custom white balance under mixed lighting
When the ambient light consists of multiple sources and you want to reproduce white more accurately, Sony recommends using custom white balance; the α6700 can store 3 sets of settings. This article only explains the in-camera functions recorded in the user manual for this model.〔G-WB-01〕
Sampling and registration steps for the α6700
In the white balance menu, select Custom 1–3, then enter the custom white balance setting. Fully cover the sampling frame with a white area and perform the capture; the camera will then display the color temperature and color filter values. Confirm and register. The sampling subjects and menu names are as described in the camera manual; for other models, please refer to your own manual. Do not treat an 18% reflectance gray card as the white balance standard specified in this manual.〔G-WB-02〕
Check sampling prompts and flash conditions
If you use a flash during sampling, the α6700 will register the white balance according to the flash lighting; Sony advises that when reusing this setting for shooting, the flash should also be used.〔G-WB-03〕
Pay attention to sampling prompts and manage registered values
If the camera indicates that the sampled value is outside the expected range (for example, if the subject is too vivid), Sony recommends resetting the white balance. Successfully registered values are retained until overwritten by other values; Sony also notes that you can open the fine-tuning screen to adjust the tone.〔G-WB-04〕
