If you're talking about spots in the center of the image like indoor on a white wall or outdoor in snow, that is also a limitation of the camera.
This PDF explains it.
Hi Ken, yes, this is exactly right. Unfortunately, it does also affect non snow type pictures. When the centre turns yellow or reddish, you need a different white balance to get those colors right than you do the rest of the frame. Its just easier to see with snow, but it happens to all pictures, and especially when you work with DNG files. Its obvious that DJI knows about this, and this is why the JPEG images already try to compensate for this, and I can only hope they reduce it even further since the JPEG files are pretty useless given the amount of noise reduction that is applied. I think the sensor/lens combo is pulling in great resolution when you have proper focus, but this can only be achieved when working with the DNG file, and since all of the processing to overcome this issue doesn't apply to the DNG file, the issue for photographers is unfortunately there, especially if you want to use the portrait function and stitch a panorama. Now the repeating centre color issues in a panorama really jump out when you look at a bunch of stitched images. I would have happily upgraded to the P4P for the better camera, but unfortunately, its camera doesn't allow it to shoot in Portrait mode, so its not all that useful for panoramas. |
