Using auto with filters on kinda defeats the purpose of the filters. However, it's difficult to determine which filter to use mathematically, because of the way the x stars camera is set up. I doesn't really tell you how much it's compensating.
The whole purpose of filters, is to shoot manual, using moderate settings on the camera for best results, to stay away from the auto compensation of the camera. These cameras do a great job, for the most part, in evenly lit mid day settings. Although, it is not a high quality professional camera...far from it. And in digital, there is no free lunch. In the old days, we controlled everything manually, and chose the film to match the setting. What film had the iso to match the light we were working with. Yes, you can set the iso of the x stars camera...but, with the quality of the sensor, you are limited. Also, when using auto camera settings, coupled with the limited quality of the sensor, you risk blown out highlights, and loss of detail in the shadows. This is why we use filters, and manual mode. We are still limited to evenly lit mid day to stay within the limits of the sensor, for really good looking media. Yes, we can pull off much more, but with it comes loss in quality...no free lunch.
So...keeping it simple. We want to shoot at iso 200, or 100. This is where our sensors shine. 200 for really bright, 100 for not so bright. We also want to stay near a shutter speed close to 1/2 of our iso setting. So, for iso 200, a shutter speed of 80-120. For iso 100, 40-80. Then, you pick the filter that makes that look good to the eye, and the histogram to peak near the center third of its range. With practice, you'll be able to "ballpark" your settings, and filter, on the fly. This is one place DJI has autel beat on the camera. Theirs will give you the plus or minus ev settings on the display, and you can pick the correct filter using that. Not that easy with the autel. Need to "eyeball it" and watch the histogram.
Thats the best way I see it, unless someone else had a better plan.
