the single most powerful piece of advice for any photographer learning about color is to shoot in RAW format. A JPEG file processes the white balance you set in-camera and "bakes it in," making it difficult to change later without a loss in quality. A RAW file, on the other hand, simply records all the light data captured by the sensor. The white balance setting is stored as a metadata tag that you can change effortlessly in post-processing software like Adobe Lightroom or Capture One.

This means you can correct a blue or orange photo with a single slider, or even set it to the exact Kelvin temperature you want, with no damage to the image file. Shooting RAW gives you a complete safety net and ultimate creative freedom. You can use your in-camera white balance to get a good preview on your LCD screen, knowing you have the flexibility to make it perfect later. //

Does white balance affect raw files?
No, white balance does not permanently affect raw files. The white balance setting is only embedded as metadata, so you can freely adjust it in post-processing without losing any image data or quality.

How do I set white balance for indoor photography with mixed lighting?
Set a custom white balance using a gray card under your primary light source. //

Can I use a white balance card in low light situations?
Yes, but ensure the card is evenly lit by your main light source and not in shadows. Increase your ISO temporarily to get a proper exposure for the custom white balance reading, then return to your desired ISO for shooting.
