Morning all
So my Mavic arrived yesterday - Woop!
I'll start with saying that I am a professional UAV pilot (UK CAA PfCO holder) and photographer.
This is my first DJI "out of the box" eperience as i normally fly large custom rigs with proper cameras on them, this is
for travel use and quick deployment.

I took some quick photos and video before i put it away and went to the pub last night, and just decided to have a look.
I havent looked at the video yet, but this photo is horrible, looke like some sotr of painting filter has been applied?!??!

This is a 100% crop of the image center, not scaled, direct from the onboard memory card.



eeew.

I have to agree with you, it almost look like a painting.
In the beginning i had the same experience.
Eventually for me it came down to testing out the different settings and so far i have no problems.
Correction, yesterday i forgot to "tap to focus" and what could have been a great shot, came out totally blurry.

Hi universal drone, certainly there are problems with your photograph , but you haven't specified what settings you used, was it auto? As a photographer you will know getting really good photographs depends hugely on yourself, so you might get more help if you let everyone know what settings you used.

I really didn't do any sort of setup at all - as I've only flown it this one time so far, this was just shot as "out of the box"

Well first I see it's very low quality download, though this is not the whole problem, I would suggest you take a look at some you tube videos, for different settings for different lighting, and just mess around with same settings you might have used on a hand held,

I can promise you with the right settings and light and a bit of post work , you can get some very beautiful landscape photography.

Put sharpning on 1+
then denoise in post,
Noise reduction in this small camera is no good, its lacking lot of detail (even if sharpning is on 0 )

And also you are indicating this is a crop of the photo - how much of a crop?  How small is this section compared to the original?  Just curious to get an idea of what we are looking at.

This is the original.

As i said the crop was a 100% scale crop, IE no scaling etc.

It was taken as a .jpg, i have to assume the jpg processing in the mavic is crap.

I'll have a go with RAW later, its too windy to fly right now (and the F1 is about to start)

From my own experience:

- as suggested above - +1 sharpening limits Mavic noise reduction which is crap - if you're flying in very bright conditions you can get away with 0 but in lower light definitely +1 works much better,

- do remember to tap to focus (or assign it to C2 button - I use C2 and it's more user friendly in my opinion),

- jpg is total crap - always use raw (even though it's Adobe DNG which is questionable anyhow - but that's your only choice) - I have only raw for stills, jpg can be forgotten from the get-go.

Otherwise - follow the above and see the results (once the wind comes down). After doing a few stills take a look at the focus quality - if it's off then you'll need to send the drone back and hope that the replacement has a better optic quality. For some reason quite a few people had the glass elements of the optics badly put together and the images are blurry (not focused).

Best of luck. Cheers!

there is absolutely nothing wrong with this picture as is, given the fact that it is JPG and that it came out of the TINY camera on the Mavic,

what were you expecting?   Canon 1DX quality?

You clearly have very low standards, its crap.
I expected something as good as or better than my £150 phone camera, and its worse, FAR worse.

However, this is in jpg mode, and appears extremely compressed and processed.
I'll be trying RAW this evening.

Obviously difference of opinion on standards of a good photo. The 100% crop is crap IMO but I think a lot of it has to do with the lighting of the scene.  Can you post the EXIF for the photo ?  Would be interesting to see shutter speed, ISO, etc. Based off the over exposed white sky I would assume the lower area was a little dark and I would not expect the camera on this $1000 unit to be able to resolve low light details like a DSLR, even low end DSLR.

Yep, that's the output quality you can expect (AND WILL GET).  Hilarious how oblivious people are when it comes to details.  The noise reduction is ridiculously strong, especially lower light (not bright & sunny) video.


Also, your trash cans aren't aligned.

Yes RAW gives you 20x more dynamic range & an infinite amount of detail & preservation of the image.  But the JPG output has always been horrible, which stinks for sure.  The Phantom 4 Pro, for example, doesn't do this.  The JPG's from that look fantastic.

i do not have low standards.   what I am saying is that given he size of the image sensor on that device and its only 12 megapixel , that is about as good a quality photo you should expect to get out of that device with its current technology.

if that photo came out of a full frame DSLR, i would be really upset with the quality.

i also get consistently poor video, it looks like that of a 640.  going to have to return this back to Mavic.    do not know if I can post the videos of them.  brought this in March.  Mt GoPro 5 has no issues.  I REALLY hate this tap to focus or the new firmware with the infinity and macro icons, they do not work.  The Craft itself flies well however.  Just the camera is no good

Sounds like you have a hardware issue there - you could link to youtube.
Certainly flies well yes, im yet to try the video in anger as it was windy and raining today.
There is some very impressive Mavic based video on the net so I think you either have hardware or setup issues.

wide angle lens should nOT be tap to focus,, my GoPro 5 has the lens set to infinity.  These are not telephoto lens or Zoom lens, that could be why all of my videos are blurred though it says "tap lightly on the screen to focus", I do but it is still blurred.  I have to send it back and get a remote aircraft that does not have this tap to focus rubbish.  I do not have the time to be engaging in that when i am trying to compose a flying area.

No I have to disagree - that first shot was utter crap, and you know it.
it is NOT a limit of the technology as my Nexus 5X has a similar sensor and lens, giving a very nice image.
No its not as good as my Hasselblad, but it was never going to be.

I have now done a shot in RAW, which has come out extremely well, no compression artefacts, no smeary weirdness - it appears to be the jpeg compression algorithm at fault.

So you said you are a pro in UAV and photographer but you used Mavic like a P&S camera and jumped right to conclusion that its quality is terrible.
You should have known everything before coming here to "ask".

As mentioned by others you can usually "fix" the bad looking jpgs by increasing the cameras sharpening setting. However, if you don't like that solution, shot raw!
I did a little testing yesterday, and the quality difference between jpg and dng/raw is huge. See last part of post here: http://forum.dji.com/thread-94609-1-1.html

UD, now that all the hubbub has died down, I wanted to add my welcome to you and to the forum.  People here are usually pretty friendly.  your initial reception was weird.  Its uncommon of people to get slammed for asking valid questions.  Bad timing, I guess.  

Anyway, glad you made it in and happy flying.

The camera on the magic is basically a glorified cell phone camera so you really can't expect to much but it does look a little out of focus, did you tap the screen to focus before you took your picture?

Hi Universal Drone,

I agree with you - the JPG you posted is far from satisfactory.

It was the watercolour effect I encountered with the JPGs since Day 1 when I received my Mavic Pro out of the box in Nov 2016. Since then, I shot RAW+JPG, and post-processed the RAWs when needed. I didn't border dialling in different in-camera settings, knowing that I would always have the RAWs when needed.

Considering the same sensor size and resolution of the Mavic Pro as those of the Inspire 1 (X3) (and also of the Phantom 3 Pro), DJI chose a different internal algorithm for in-camera processing of the Mavic Pro JPGs, which sharpens too much the image and suppresses too much image noise.

Henry.

if you read it he says it's 100% crop of center.  So its pixel = pixel crop of the center eg. the center 1188 × 735 pixels
