Visibility III / V
I woke up at five in the morning and went hunting with a drone on the Moon. The attempt of the previous morning had crashed to the rocks right from the start, when the drone refused to ascend, but demanded that the compass be calibrated. Well, I couldn't do it in the dark without a manual. Fortunately, the trouble later recovered on its own.
This time there were no problems with the drone, but the dilemma was to find a decent fog. I set off to drive to the destination I was thinking about in advance. Already a couple of miles away was the first fog ferry over the road. I stopped at it and lifted the drone into the air. I took a couple of pictures, but the fog was scattered and I wasn’t very happy with the pictures. I continued on my way forward. Just to find that there was no fog at all on the target lake. A small search followed and the fog was finally found. Again a drone in the air and take pictures. Although the fog was thicker, the day had already turned a little brighter, and the arc was no longer visible in the pictures properly ... The lens could also go into fog, hard to say. At least the drone was damp when I took it down. In the dark, operation is quite challenging when you can see almost nothing on the controller screen. To find the correct shooting direction, you must first take a picture that allows you to orient the camera better. After all, I got experience and a few fog arch pictures.
The main image is a 3x3 "wide angle image" taken by the drone from the first location, followed by a single alignment image before it. The third image is another 3x3 image from the latter location. Images are unprocessed directly from the card. All the same values: f / 2.8, ISO 6400 and time 8 sec. So it takes more than a minute to fly to capture such a 3x3 panorama. One wonders how that racket can make valid multi-image panoramas, even in pitch black. You can see from the triangle image that it doesn't always work out perfectly. There were a couple of degrees of frost at the airfields.
