Firstly, lock the exposure so it doesn't change. Choose one a bit darker so you don't have all the snow without any detail. You can adjust brightness post production to fix that but you can't fill in overexposed areas if they are shot that way. Secondly, click on the subject you want to shoot on the screen of your device. A focus square appears and changes the light to suit the subject. Most people don't use or know about this function. The light and colour shouldn't change if you lock the exposure with your subject as the focus.
Those are good tips!
But the White Balance issue is a different problem. What people are asking for is a way to lock the WB so that colors don't shift as the automatic WB tries to adjust to different color temperatures.
Snow is often problematic because as your angle to the sun changes, the polarizing effect of sunlight striking the snow can shift. Also, as you change your angle to the sun, the same sort of effect happens due to scattering in the earth's atmosphere, also causing a shift in the average color temperature that's "seen" and adjusted for by the auto white balance. Water also polarizes light that reflects off of its surface, and this, too, can cause an apparent WB shift depending on how the camera's sensors are affected.
And flying indoors, you often have different light sources as you move around. One room might have LED lighting, another might have fluorescents or incandescents, etc.
I've noticed that as I fly from room to room where I work, the shifting of WB as the Mini attempts to adjust automatically, can be somewhat disturbing.
Any auto white balance will attempt to make the overall average scene appear as if it was photographed in daylight. But this isn't possible with "mixed lighting" as still photographers know. Fortunately, you can correct a still image (especially if you shoot in RAW). But the issue with video is that the WB setting that the camera is using can change as the aim of the camera changes and it tries to adapt. Seeing the colors in one part of the scene change as a differently-illuminated area comes into view and begins to dominate the WB setting is odd, and attracts the attention of the viewer.
While no one WB setting will allow every part of a scene that suffers from mixed lighting to look as if it was shot in daylight, at least the colors won't change. People understand that different light sources yield different color balance. That's hidden from us to some extent by the amazing way our brains compensates for these things. But we're still aware of it from our everyday experience.
As an example: Everyone knows that the light from a campfire renders things with a reddish hue while light from the sun is more "white". I often think people go too far when color-correcting still photos to try to make such scenes appear to have been shot in daylight. Often, it's best to leave at least some of a scene's tint alone so that it conveys more of the feel of the actual situation.
Being able to at least lock the WB, and ideally be able to manually adjust it is a handy feature, and shouldn't be difficult for DJI to implement with a firmware update.
I think the Mini does a great job. But having more control over WB would be a nice upgrade. |
