BTw, how good are the 48MP images of your drone?
I'm guessing that perhaps they are not very sharp if viewed at 100%. How about the dynamic range - is that a limiting factor and when? -- Alfred Molon Olympus 4/3 and micro 4/3 cameras forum at https://groups.io/g/myolympus https://myolympus.org/ photo sharing site |

So with that to consider, and understanding that it is not an M4/3, APS-C, or FF camera, with thoughtful ISO, and exposure setting selection the stills results are acceptable for most social media sharing purposes. However, the 12 MP images are not too bad. These are 48 MP examples: https://photos.smugmug.com/Air-2-Work/i-CKSbqP4/0/129f7df5/O/DJI_0098e.jpg https://photos.smugmug.com/Air-2-Work/i-XtJcPFD/0/8083e6b5/O/DJI_0083.jpg ....and this is a 12MP shot: https://photos.smugmug.com/Air-2-Work/i-RD2tW5X/0/22b47e32/O/DJI_0041e.jpg I'm guessing that perhaps they are not very sharp if viewed at 100%. If you are going to pixel peep, they are not going to stand up to the scrutiny that you might subject an M4/3, APS-C, or FF image to. How about the dynamic range - is that a limiting factor and when? In good light, with average contrast it is acceptable. Once the light is such that you have deep shadows the ½ inch sensor has a big drop off in performance when compared with the 1 inch sensor on the much more expensive Mavic 2 Pro. However, the enhanced image option produces surprisingly good dynamic range images. Then there is always the option of shooting an exposure bracket to use for HDR processing. This is what the enhanced 48 MP image can look when a solution for questionable light is needed. https://photos.smugmug.com/Air-2-Work/i-mDgKhpT/1/feabfdb5/O/DJI_0014E2.jpg -- Regards, Savageduck |

Have you checked if the sharpness improves with RAW processing? Both of those were processed from RAW (DNG) originals using Lightroom Classic, some sharpening, and noise reduction was applied to both. -- Regards, Savageduck |

You've already seen for yourself that you must take your 360 degree turns much more slowly so that folk viewing can keep the image in focus. Overall I'll score you 9/10! :-D Thank you for letting me share. -- David |

Using QT player. That sounds more like a bandwidth issue rather than a problem with that particular iMac. Also, accessing that file from the iCloud link with an iMac will usually open wit QT player rather than via web browser. With QT player viewing at full screen is a simple option from the view menu. The image quality is very good though , will try it out tonight on my home iMac with SSD. The thing was to see that you got the file at native resolution rather than what SmugMug was delivering at your end. The important thing is, that you were able to access the iCloud version. -- Regards, Savageduck |
