I can only speak from my own personal experience but I would suggest that anyone who has a Phantom 4 Pro and has found this thread just not use Pix4DCapture. Use another app like DroneDeploy for capturing data and then Pix4D for processing if you have a subscription. This is a problem that has been happening longer than I have even had a drone, since March 2017, almost two years according to this thread and is still not fixed (at least for iOS).
We have a company iPad we use with our drone so I don’t know if the problem would be fixed if we used our personal Android phones. I do know however, that it is fixed when we use DroneDeploy. DroneDeploy allows you to set your shutter speed so that the exposure time never gets longer than 1/200th of a second. We have found that every single flight we’ve done that has blurry photos on Pix4DCapture (almost all of them) contains many photos with shutter speeds longer than 1/200th of a second (1/120th, even slower). This leads to blurry photos. The areas we are flying are much too large to stop the drone for each photo, as this greatly increases flight time.
We’ve followed all the Pix4D articles on setting up our Phantom 4 Pro’s camera, setting all of our camera’s settings in DJI Go as they suggest and it still leads to blurry photos. The blur is not the worst, but it is still there and noticeable. I think John Whitten’s photos best show the type and amount of blur we were getting. Note as icubedtoowong showed, that this blur does not show up in DroneDeploy, or as others said, when taking photos manually in DJI Go, even with the settings in that app set to Automatic.
Honestly, (again) as others have mentioned, it’s ridiculous that you basically CANNOT use Pix4DCapture and a Phantom 4 Pro, if you have an iOS device. I’m assuming this problem has been taken care of in Android, but it with all these comments, I would not be surprised if it was not fixed still. And it’s ridiculous that Pix4D has been allowing this to happen basically since the Phantom 4 Pro was introduced.
Please Pix4D: fix this problem. Either figure out how to properly apply the DJI Go automatic focus/shutter/ISO/etc settings properly in the Capture app or add an option in the Settings menu to manually set a (maximum) shutter speed. It’s been 2 years.
Hello Chris,
Are you using a Phantom 4 Pro V1 or a Phantom 4 Pro V2?
A fix has been released recently and solves focusing issues that were occurring on the P4P V2.
You can download the latest version of Ctrl+DJI here.
In a general way, using the iOS version of Pix4Dcapture the camera parameters cannot be set manually. Note that we have a lot of satisfied users for this particular drone and that in most of the flight plans and conditions, the images will come sharp and will be processed without any issues.
If still experiencing blurry images, the suggestions at the moment are to use the Safe mode to trigger picture or to reduce the speed of the drone using the speed sliders in the settings.
Then I agree that having better control of the camera settings would improve our application and I will share this feedback with the developer’s team but it is not in our pipeline to change that for now.
Thank you for your understanding.
Best,
i use IPAD and pix4d using phantom 4 pro V2, the image is sharp and clear. i take image on 11.15 am february 13, 2019. i think the focus issue have been solved.
appreciate for pix4D team!
Phantom 4 Pro V1. So is our solution to use our personal phones to fly with android? To me this is unacceptable. Or is it to buy a new P4P V2 drone or Mavic 2 Pro? I don’t know specific numbers, but if we used Safe Mode for some of our bigger jobs, our flight time would go from 30min, to over an hour. Why do that when we can fly in Drone Deploy, which will guarantee the proper shutter speed and thus clear photos. And possibly even have less than a 30min flight time?

Just curious Sigit, what height did you take that photo at?
Phantom 4 Pro V1 here. AND. iOS blurry from soft focus. not shutter speed. tried all suggestions re setting 1 auto. 2 dji go auto and manual 3. dji auto and manual with force quit thereafter. 4. tried two and three while in the air as well. Will try Drone deploy as all are saying, BUT really want to shoot at an angle (not straight down) while in the grid. drone deploy does this with a finish up perimeter, but not like pix4d which does it in a grid. coming from 18 years photography, re don’t need a link to how cameras work.
Hello all,
Thank you for the different feedback.
As previously said, the P4P V1 is the most use drone with our application and so far we had no feedback about blurry/out of focus images. Also in the past, some focusing issues have been solved on the P4P V1.
Are you experiencing blurry images all the time like it was the case for Sigit on the P4P V2? Can you send us some blurry pictures that were acquired with Pix4Dcapture and telling us your mission settings?
Best,
This is an example of a clear vs a blurry photo we’ve been getting. The photos were taken less than a minute apart. I rotated one of them so that they would be in the same orientation. The first 15 or so photos were blurry like this and the rest were clear. But the job was only 46 photos, so a quarter of the job was blurry. Any ideas?

Hi Gael,
I’m getting blurry photos similar to those shown by Sigit when using a Phantom 4 Advanced on Android.
I have tried multiple different focus settings but photos are always out of focus. I have managed to change shutter speed so i know that is not the issue.
Cheers,
Hi Andrew,
The Phantom 4 Advanced is not supported by Pix4Dcapture at this time, that might be the reason you are getting this error.
For any focusing issue, the best solution is to fly the drone at the height you want to do the image acquisition. Using the DJI Go app, tap on the screen of the app to do the auto-focus. Then, close the DJI GO app, and start the mission using the Pix4Dcapture app.
Regards,
Hi Kapil,
I believe the Phantom 4 Advanced and the Phantom 4 Pro are essentially the same but the pro has extra sensors. Camera settings should work the same?
My problem is that focus settings from the DJI Go app aren’t coming through to Pix4d capture so this will not help,
Cheers,
I know this is an old post, but I’m new to mapping with drones and am trying to troubleshoot some blurriness issues. I’m wondering if all camera settings were the same, wouldn’t it be logical to suspect an enviromental change to be the variable, such as more wind gust, or change in lighting from time of day or cloudiness?
Also, is it possible to set a minimum/maximum range for shutter speed and aperture?
Hello,
There is no option to set the minimum/maximum range for the shutter speed using the Pix4Dcapture app. For more information, I would recommend you to go through our support article on How are the camera settings taken into account using Pix4Dcapture?
