Hi,

Ever after getting back my mavic air after DJI repair i feel like there has been something off with the drone itself.
Yesterday we were taking some pictures on a mountain and it wasn't that windy.

Does anyone know what can help the picture? Or is there something wrong with my camera?
I have tried IMU cal and new props.

Here is also some other pictures:

ND filters, camera profiles and light will all impact as will frame rates, ISO and shutter speeds.

You talking about adding or removing ND filter? I are flying with DJI ND16. sunlight was from behind at the 1st picture.
Might it be the ND16 filter with the ISO400?

Definitely out of focus. Did you try to take some photos in different conditions, different times of day? I would first do that, and see what happen.

Did you see the 3 other photos i have uploaded? They are from 3 different days and conditions.

Saw them, all look out of focus. Only way that a ND filter could have negatively affect the images, is if it made your shutterspeed to slow for images. That could introduce motion blur on a drone, and the blurry look.
Have to be honest and say, that no, i don,t think that is your problem here. You have good daylight, and they all look out of focus.
I would probably send it back, again, if it where mine. Could be the focus mechanism of the camera that is out of whack.
Does your videos look sharp?
That images is un usable. Let us know about video.

You don't want to make photos with a ND filter attached except when you want to make long exposure photos.

I once did some photos aswell and I forgot that I had my ND filter attached from video filming before, the pictures were slightly blurred because the shutter speed was too long and small movements can make your picture blurry. Test it again without ND filter.

Uploading video to youtube. The video seems fine, that is why im asking. Maybe I am doing something wrong.. you never know ;)

Seems like this was my settings, 1/640s ƒ/2.8 ISO400 4.5mm.
Im just a noob in these things, but is 1/640s a long time for a bright day?

If the video is sharp, the focus should be fine. Then, test it without the ND, or make sure you get your shutterspeed around, or above 60, if none windy conditions.
Always remember, if you do use the nd filter, to make use of the general tips for photography with a nd filter.

I will try without the ND filter, thanks for the help so far I will come back with my findings asap.

Are you aware of the basics of ISO, Shutterspeed and Fstop? That is the 3 things that will help you to decide what you want your shot to look like, and then, what you have to do to get it like that, and also, if the time of day is correct for that.

Im basicly trying to keep my ISO at 100 and adjusting the shutter speed after the zebra lines on the photo i want, so i dont lose any info.

Hi James, have you tried to reset the camera settings to check? If the issue remains, please kindly provide us with the last repair case number and original pictures in the SD card for better assistance, thanks so much!

Well, even more obvious it's the ND filter then, if your video was fine. Don't use ND filters if you take normal pictures, as I said.

ND filter removed and camera settings reset, thanks for the help so far. I will come back to you if this solved my problem.

Btw, mavic air is awesome ;)

The video not only looks fine but definitely super amazing
keep sharing please

Video looks great. More than likely your photo settings need to be tweaked than a hardware error. Let us know what resolved the issue so others can learn as well.

So in my opinion my issue is solved. Removing my ND filter and reset of camera settings made everything better.

Nope, that 1/650 is not how long the shutter is open, but how fast it opens and closes. So, that is 1x650th of a second, that is super fast. It will freeze the image, as well as freeze motion, like waves, more.
If it is, let say, 1/60 or lower, the shutter actually stays open longer, so more light get in.
That is the basics.
Have to say, i use nd filters on many, many of my photos. I also do all my landscapes with nd filters with my dslr. The drone ND filters is just a bit more finicky, and needs to be precise, to work nicely. Problem is with drone, you can not just take it off quikly, and change as the light change. Have to land, and change.

Also, not to be tooooo critical, but your video is much, much sharper than the last photos, still not sharp, slightly out of focus.

At ISO 100, with a f2.8 (lots of light, wide open, but no option to change on the MA) and a shutterspeed of 1/2000, i freeze birds in flight. That is fast, so you should have a super sharp image.
Okay, i downloaded the images, does look a lot sharper on the download, not when opening on the net.. Now, do yourself a huge favor, and go and practice some with nd filters, they will give you amazing results with photos, if you use them correctly.

Would like to see these clear, cool shots

Hi James, glad to know the issue has been figured out, please refer to Charissa's suggestion and enjoy flying, please let us know if there is any more issue.

That is the basics.

Actually, 1/1650 is the time that the shutter is open for, we have no control over the speed of the shutter opening and closing and if we did it would be expressed as a speed function not a time function. Shutter speed is a misnomer, it is more correctly called exposure time or Tv.

I believe confusion is coming from how camera's with bladed shutters work.
First blade starts moving downward, allowing light to pass to camera's sensor.  (The opening part)

1/650 of a second later the Second blade starts moving downward, to block light from passing to camera's sensor. (The closing part)


The following video shows how a camera with bladed shutter works.

Ye thats cool Thats for teaching me a few more things, and to make things easier for me in the future.

True.
But then, we do have some control on how fast the shutter open and closes, by setting the ISO, the fstop. That is what we all do, when we change from taking, for instance, bird in flight shots, which needs a fast shutter speed, to taking landscapes, that we can use very slow shutter speeds in.
If we honestly did not have any control over SS, we would have found it extremely difficult to capture fast subjects and freeze it.

And, 1/650th of a second, is still a fast shutter speed, and the correct time that the shutter is open, as I said.
I did not want to make it to convoluted to the guy that posted the image.

Things will come in time. Just needed to explain the basics.
Also, we generally use Shutter Speed, and not shutter time, in our parts of the woods. 1/650th of a second, can definitely be measured in speed. As well as time.
Same principal, just that you would measure it in time, where we normally measure it as speed.

Perfect.
That explains it well. Still the same principal, the 1/650 th, if you don,t go into it too technically, is the speed/ time the shutter opens/closes, and thus, the time light get introduced on the sensor.
Easy as that. Faster SS, less light, less motion blur. Slower SS, more light, moving objects get more blur.
Cool to do such a thing with cameras.
