There are definite advantages to the DJI fully automated 360° pano creation from 26 20MP originals, all shot and stitched together in camera within a mere 60 seconds! Sometimes, efficiently trumps perfection!
How to take HDR 360 with AEB automatically
- Thread starter Andrex
- Start date
If i use 5 bracketed jpeg AEB exposures (not raw), Litchi will made the pano in max. 3-4 minutes.
If there is no or little wind, i dont have drifting or altitude change.
Main problem is that EV steps is small, sometimes i need more, but DJI sdk doesnt allow! Why?!

How many photos in total is that? I can't remember my settings for no. of columns, but I ended up with 34 sets of 5 brackets (170 photos).
As I've said to you before, it's (potentially) a trade off. Look at the photo I linked again. If I used DJI Go, the entire part of the town under the sun would have been overexposed and white, as it's shooting directly into the sun. Most of the rest of the shot would also have been exposed incorrectly. The actual issue I have with a part of my photo is probably less of a percent of the full image which is dodgy than the amount that would have been blown out if I had used DJI Go...

You might actually have some lens flare going on right there. I don’t think there’s much you can doRevisiting this almost a year on (because winter is when you tend to need to use HDR more to beat the low sun) this is today's shot from Shrewsbury in flood.
Unfortunately using a 5-bracket AEB in Litchi means the 34-shot panorama took some time. What seems to have happened in the 5-10 minutes it took to complete a circle is the drone drifted in the wind (slightly) and also appears to have lost 10 m in altitude, which I didn't notice during shooting. The panorama started at c. 75 m above ground.
The result is unfortunately an issue in stitching the start and end seam of the panorama (parallax, and also a lack of sufficient overlap, but I think mainly paralax). Disappointingly, this is most pronounced for two of the town's spires - in the opening shot, the spires were below the horizon, but come the final shot the spire tip was above the horizon.
I attempted to manually fix in photoshop with clone tool, dodge, burn and the original frames, but I have struggled.
Apart from one slither of the photo representing probably 5 degrees, I'm happy with the rest. But a five degree aberration is pretty significant in a photo like this.
Lessons? Not sure. The naked eye probably wouldn't pick up on the potential parallax over 10 minutes of auto-pano shooting in particular between the start and end frames. A drone can drift a lot in 10 minutes. Better keep an eye on the altitude reading next time I guess. I don't think anything more can be done in post-processing to save it.

The question was answered over a year ago and your reply doesn't help - the use of Litchi was reccomended some time ago. You didn't even make it clear which app you suggest using.
