This is one of those photos built up from multiple shots and stitched together. Taken on a Mavic Pro.
Because of the relatively low angle for the distant landscape but very steep angle for the foreground, lens distortion made stitching more luck than judgement.
This is the penalty of relatively low altitude shots with a large difference in perspective. In the end, I stitched patches of several frames and then adjusted the perspective in Photoshop CS so those patches would stitch to form a whole picture. It was then necessary to adjust the perspective again and crop away all the jagged edges.
The resulting image size is a massive 4944 x 2992 at 300 dpi and a bit depth of 24
Exposure was 1/40, ISO 100, Exposure bias +0.7 so the process was manual to keep all images lit the same. I worked from the DNG (or RAW) files because, at that time of the morning, the unlit town was very dark, compared with the bright sunrise. With so many frames to stitch, there were 37 altogether, stacking was not a reasonable option.
Wind was about 5 miles per hour and no gusts.
I was delighted to see the clarity of detail in the final 15.5mb image, after flattening. It is a pity the reduced resolution image shown here has lost all that. An enlargement of some small yachts in the harbour still shows the faintest lines of their rigging. Not bad for a drone camera, I reckon.
