RAW + JPG + Bracketed no workie...

[Donnie Frank]

Hey doods...

I shot some real-estate this evening with the ol' Mavic Pro. The client requested RAW + JPG photos. For photos, I always shoot bracketed. But tonight something weird... Instead of getting three bracketed photos, I got three equally-exposed photos. Now, for the occasional real estate client I always shoot bracketed. But I never shoot RAW for real estate, as most real estate agents don't know how to handle RAW files. This is the first time a real estate agency wanted RAW + JPG files.

Here's a screen shot of the thumbnails. You can see that all the exposures are exactly the same.



Has anyone else experienced this? If the Mavic Pro can't shoot RAW+JPG+bracketed, I would think it would net an error message.

My MicroSD card is a SanDisk Extreme Pro, 64GB, and is functioning perfectly.



What gives?

Are you sure you have it on bracketed exposure and not timed shot? It looks like a different angle in each photo particularly the bottom row so either you have it in timed shot instead of brackets or your drone has a rocket strapped to it and was able to fly from the side of the building to the front in the lower row all before the bracket finished.

I’m guessing it might be on timed shot accidentally

Are you sure you have it on bracketed exposure and not timed shot?

Positive. The secondary HDR menu offers only 3 options: (3, 5, 7) shots. The secondary menu for "Timed Shots" offers 9 options denoted in seconds or "s." All the shots are consistently 3 images each. I believe the "TImed Shots" are for however long you hold down the button.

There are three shots per subject. Sometimes, if I think the bird was moving during the HDR shots, I shoot again. So there's some extra redundancy there.

Plausible theory, but quite impossible, I assure you.

Well this actually goes to my theory because the AEB menu only has 2 options, 3 or 5. “Multiple” is the option that has 3,5, or 7. I really meant my theory was that you have selected “multiple” or more commonly referred to as “burst mode” not “timed shot” sorry about that.

I think this is likely as it is easy to do. “Multiple” does not change exposure during the burst shots but AEB does.

And now I see this is three stacks of three not two stacks of 5 so forget about what I said about the different angles, the three images in each of the stacks are from the same angle. Obviously

That's exactly the same menu I have with DJI Go4 and my Mavic Pro Platinum. Only have 3 or 5 for AEB.

Looking at your screen shots, it's possible I selected "HDR," which I ASSUME means bracketed shots. But now that I see there is an AEB option ("Automatic Exposure Bracketing, I assume)", I'm positive that AEB is the option I USUALLY select. It's been a while since I used the Go 4 app, so I probably saw "HDR" and erroneously ASSUMED that the shots would be bracketed, and therefore selected that. I'm not sure how taking 3 equally-exposed shots facilitates "High Dynamic Range." Idiotic. Yet ANOTHER DJI gaff.

I'm sure I selected HDR last night, which appears to do nothing more than duplicate equally-exposed shots.

Mystery solved. Lesson learned. Beware the HDR option...<sigh>....

Thanx!

The onboard HDR leaves a LOT to be desired IMHO. It's a waste of screen space from my point of view.

One interesting thing I found, however, is you can stack HDR shot WITH AEB so you get 3 or 5 bracketed "HDR" shots which can then be merged manually to in theory get a bit more dynamic range than a single shot AEB stack.

Can you please explain what this HDR setting does, and why it takes 3 shots per image? All three shots are exposed equally. So where does the "High Dynamic Range" come from? How is that achieved with 3 duplicate images?

I'm not "Fluent" in DJI's HDR setting but the only time I used it (a couple of years ago) it only produced a single HDR image on the SD card. I do remember it actually snapping 3 images and then doing a so-so job of creating a single HDR (combined) image. It just wasn't enough "range" for me to even consider letting the aircraft do the combining onboard.

Gotcha...sounds like snake oil to me. Fortunately, I took RAW shots, as well. From what I can see, the RAW photos have enough dynamic range to bring out the shadows. Nothing's crushed or blown out.

Many times you can do a LOT more with RAW files if you know what you're doing.

Actually I have been known to run a single image through my HDR program and had very good results (yes a single image) so long as nothing is crushed or blown out. It's a feat to battle over exposure.

HDR doesn’t actually save 3 photos unless you also selected “multiples” as well.

HDR which I like to call “auto HDR” is where the camera takes 3 or 5 photos (don’t know which) and then merged them into a single composite in camera. Even though multiple frames are taken it only saves one.

I’ve looked at the raw files produced by this mode and they are larger (more information) than a single shot frame So it IS an HDR photo but personally I’d rather have Photoshop or Lightroom make the composite with the full power of my Mac rather than in that camera in a split second. That way I can also make decisions like ghosting settings and such.

Most cameras these days have a feature like this even your phone but none of them are very good.

That's not what happened with me. My Mavic Pro simply saved all 3 photos of each image as duplicates. Was I supposed to do some kind of post-processing once landed???

I hear ya. And I agree. But all my Mavic did was take triple photos of each image, both in jpg and raw, for a total of 6 redundant photos per snap.

Copy that.

Scratch this I actually manually took three “auto HDR” photos at different EV levels. My bad

Well since you already think you choose the wrong setting dont you think it’s possible you accidentally chose “multiple” instead of AEB since it’s right next to AEB?

Since you thought there were options for 3,5,or 7 photos which is only available in “multiple mode” and is a reasonable option for and is easy to confuse with AEB not to mention your drone actually acted as if it was in “multiple mode” not to mention you aren’t the first person to have done this (I’m actually having dejavu right now Mavic Air AEB problem)

I’m pretty confident you were in “multiple” even if you thought you selected something else. Maybe you even selected AEB but your DJI Go 4 registered it as “multiple” mode.

It’s pretty clear to me what happened honestly.
