Hi. Last weekend I tried Pano Mode - Sphere in my spark. The result of this is here:

https://www.skypixel.com/photos/ ... 5-827a-83778724bf4b

I don't know why my 360 photo is sooo low quality.

I see another 360 photos taken by spark and the quality of this is much better. For example:

https://www.skypixel.com/photos/ ... 0-b6b7-9de002df5f6c

https://www.skypixel.com/photos/ ... 7-ae9f-273e50057cb7

https://www.skypixel.com/photos/ ... 0-8429-fe41144f4efd

Another thing is the light. What can I do to make light better. In my case that day has some light, but when spark putted the camera down (taking all sphere photos), the light in photos became dark.

Can someone help me?

Thank you.

How did you stich the Sphere pictures together?
With the App?
Do it external.
On a Computer, with MS ICE (freeware), you can create very high pixel "Flat"-Spheres.
Reducing 'em then to 8000x4000 for skypixel gives you probably the best quality you can get oit of the spark pictures.

For the brightness thing:
If you let the spark do this exposure lock by itself, it will always set it for the sky!
Fix the exposure somewhere in the middle between the autofix (first shot, sky) and the "full down" picture.
Either by tapping on the screen (yellow square shows up) and aggain to lock, in the yellow square.
Or set one of the customizable buttons to "exposure un/lock"

I doubt that, but I do not know for sure!

But here, why I doubt that:

How big is the picture (the flat "sphere") you can save on the phone?
I have saved a couple, when travelling, but it is only 4096x2048 (I think), right?
So you produce a 360x188 degree picture even smaller as every single picture is.
With the App you won't get better quality, I think.
I am not aware of other apps for the phone, that could do the stitching and saving.

But for ICE, even the 8000x4000 (I think that was the average or maximum skypixeln Sphere size for upload) is about 4 times the size of your phone creation.
And ICE seems to have a very good algorism, to calculate a picture from a sixe of nearly some hundred Megapixel down to 20 or 30 Megapixel.
And it is doing that in the END of the process, which I do not think that the go4 app is waiting till the end. Simple not enough Ram and memory available, methinks!
Also the jpg creation seems to work, if 90% quality is chosen.
You can even save a TIFF, PNG. If you wanna use that much memory!

All this are things, the DJI Go4 app is deciding by program, not by you!

So my "educated guess":
Go4 App Spheres are optimized for "straight to social media".
Not for "best quality"

Actually, I would really like to watch your Sphere from the top in good quality.
Here something like that, which I created with ICE:



It is really worth it, methinks ;-)

Sorry, no idea.
But I have to assume that they are "bigger" as 4000x2000 pixel!
So probably not made with the app.
Contact the people and ask?
