New Auto White Balance Options: White Priority & Ambience Priority

My wife, Amanda, upgraded her Fujifilm X-T20 to an X-T4! Video-wise, the X-T4 is a huge upgrade; stills-wise, the X-T20 is a solid camera, but the X-T4 is a little better. The picture above shows Amanda with her new camera, captured with my Fujifilm X100V using a new film simulation recipe that I will publish very soon! The Fujifilm X-T4 has two new Auto White Balance options: Auto White Priority and Auto Ambience Priority. What are these? What do they do to your pictures? Let’s take a look!
For Auto White Priority, the manual says, “Choose for whiter whites in scenes lit by incandescent bulbs.” And for Auto Ambience Priority, “Choose for warmer whites in scenes lit by incandescent bulbs.” Essentially, Auto White Priority is the same as Auto White Balance, except it has a cooler tone under artificial light, and Auto Ambience Priority is the same as Auto White Balance, except it has a warmer tone under artificial light. In natural light, all three are the same.
The pictures below show all three Auto White Balance options under natural light (using my Kodak Ultramax recipe). Can you tell which is Auto, Auto White Priority and Auto Ambience Priority?



Which is which? I have no idea! I can’t tell the difference. The three images look identical to me. Even when I closely examined the three full-resolution files, I couldn’t figure it out.
Under artificial light, the differences between Auto, Auto White Priority, and Auto Ambience Priority becomes much more obvious. You can see in the pictures below that Auto White Priority is cooler than standard Auto White Balance, and Auto Ambience Priority is warmer than standard Auto. Take a look!



Of the two new Auto White Balance options, I’m most excited about Auto White Priority, although I think in some situations Auto Ambience Priority might produce nice results. The new LomoChrome Metropolis film simulation recipe that’s on the Fuji X Weekly App requires Auto White Priority, the first recipe to use one of the new White Balance options. I think there’s some good potential for incorporating these new options into new recipes to create different looks. Now if I can just convince my wife to let me borrow her new camera….
