First test flight tonight around sunset. Missing auto bracketing but hopefully this will be an easy thing to add later via firmware/software updates. For this one I just manually took 2 photos by quickly clicking the sky (first) and the ground (second). View attachment 85863
I guess I'm confused - your first shot was straight on and your second shot you gimbled down or tilted down to get the ground? Then you blended them in a program such as Photoshop? Sorry, very new to this idea

No, they focussed on the ground to get a brightness level for the camera and then they clicked on the sky to get a brightness level for that.
They then merged the two.

I'd not actually thought of that so I'm going to have to try this myself later.

Yep, exactly @chriscuk. I used Photoshop to merge the images. Only issue is that the "remove ghosting" option wasn't there...perhaps because I only had 2 source images and/or because the file format is JPG but not raw?

At any rate, will continue fiddling around with this, but seems like a good potential solution to get a lot more dynamic range out of images provided there isn't a bunch of motion!

Complete newbie here, but this got my attention. I'm a big fan of HDR from a fixed camera, but I never considered it to be useable/useful from a drone. Is "Photo Bracketing" the same? In my ignorance, I would have presumed that the multiple exposures from a bobbling-about drone would be difficult, to impossible, to merge.

Yes, definitely possible with a drone. As long as you're not super close to an object, stability is great so the "bobbling about" issue isn't really a big deal. The main thing is sorting out ghosting with things like traffic (as you'll see in the example I posted) but this can be sorted out in Photoshop with the right amount of fiddling.

Well I just tried and got a big load of fail :D
I think it's too windy where I am at the moment. I think gusts were around 25mph just now so had to give up then lost the light.

I had a couple that almost worked but they were not perfectly aligned so I gave up.
