    Did you just go fly and take a pic in auto, or did you do a little research here on what others were doing for night shots prior to flying?

    I have done a few night shots. On auto they, much like yours, turned out like crap.


    On manual, thats another story. And these are NOT HDR.

    There's nothing wrong with using auto and it wouldn't create any issues like what you are looking at.
    In that one, the problem was with the in-camera HDR function, which is generally regarded as not worth using.

    You don't have to be in the sky to experiment with picture taking. You do need to turn off the red leds on the front though, especially when taking practice shots on the ground but it's also needed while flying too. Try auto and see how it goes. Try manual with a low iso and experiment with longer shutter speeds, but you'll do better on the ground with longer shutter speeds so don't be fooled. Airborne, 2 to 3 second shutter speeds is the best you'll probably do. Also when practicing on the ground avoid really dark areas. Super dark won't work well in any case, on the ground or airborne. Some available light will be needed for best results.

    Thanks buddy, that's the plan of action for today then I guess, once I've experimented I'll post what the problem is so anyone else having this probleM will know, just hoping it's not a faulty camera or firmware related, thanks again, I'll let you know if I get to the problem or not

    Could you put that DNG on Google Drive and post a link? I'd like to try developing it in my software. It looks like a combination of a white balance and black level issue where the red and blue channels are not finding their range properly. Might be fixable.

    Regards,
    Mike

    It's not really that confusing. Break it down this way.

    To use a photo drone, you need to learn to fly first. I'm not talking about pushing buttons or relying on automated RTH and other features of the drone to keep you flying - I mean you have to learn to pilot your drone yourself. That's step one. If you can't fly - you can't take pictures or video.

    The other part of the equation is - to properly use your camera, you need to learn to USE the camera and learn about photography. I can tell you for certain that anyone who tells you you can take good photos without understanding how things like shutter speed, aperture, ISO etc, affect the quality of the photos you take with your drone, 1) doesn't have a clue about photography, 2) has a low standard of the photos/video they take or 3) is satisfied with one in four photos coming out "ok".

    So: Learn to fly first, learn to use the camera properly second.

    Lastly - EVERYONE has to stop blaming the camera for their lack of photograph skills - if you're using "auto" settings - you're willing to take what you get. I'm not.
    Good luck and fly safe.

    I don't disagree, but that said, I've tested and written code for raw photos from hundreds of cameras and have never seen one that will blow the red and blue black points in a raw, even in auto mode. I could see over or under exposure or even noise as user error, but it's odd to see a raw that looks reasonable for midtones and highlights but shows what looks like clipped red/blue channels on blacks. To me, it looks like something that could be "fixed" by firmware. To be fair, the camera is not a DSLR so you can't really treat it as one. Any tool has it quirks so you have to just learn how to operate it within its limits/capabilities.

    Without taking a lot of time to fool with this.

    Like I said - learn to fly first, then learn about how to use the camera.

    Thanks for the DNG. It's definitely strange. Everything is fine except the blackest blacks which have random full brightness red, green, blue, magenta, yellow, and cyan dots. As if it doesn't know how to handle black. I tried running that DNG through the DJI DNG cleaner figuring maybe that's what it's for... but the DNG cleaner corrupted the output DNG file so that nothing could read it. Is that DNG straight from the camera card? Or was it resaved via some other software?

    Seriously... I know how to fly mate without being rude, what makes you think I can not fly.... Nor use the camera, I have been a photographer for many years and an Astro photographer check my Flickr via my images I posted above, you should not just assume, I do not mean to be rude one bit but I feel your post is a tad rude my friend
