[QUOTE="Der olle Hansen, post: 117318, member: 20475"] The quality of the pictures (stills and the optical illusion of moving images) is influenced by [LIST] [*]the quality of the [URL='https://en.wikipedia.org/wiki/Objective_(optics)']camera lenses[/URL], [*]the size of the [URL='https://en.wikipedia.org/wiki/Image_sensor']image sensor[/URL] (size does matter!), [*]the settings of the camera ([URL='https://en.wikipedia.org/wiki/Aperture']aperture[/URL], [URL='https://en.wikipedia.org/wiki/Shutter_speed']shutter speed[/URL], [URL='https://en.wikipedia.org/wiki/Film_speed']film speed[/URL] (ISO), [URL='https://en.wikipedia.org/wiki/Color_balance']color balance[/URL]) and [*]the quality of the [URL='https://en.wikipedia.org/wiki/Video_codec']video codec[/URL]. [/LIST] What then comes out of the codec as a mathematic calculation result is the maximum quality that can be obtained due to the technical requirements and the manipulations by the user. [B]The SD card is just a neutral place to store this result.[/B] As already described in the previous post, the memory card only has to be fast enough to be able to save the enormous flood of data quickly enough and without errors. Most SD cards do not forgive one mistake that is often made: If you switch off the drone while recording (and writing data to the card) is in progress, this video file is destroyed - in this case the quality is zero ... And last but not least, the "image quality" also depends on the image composition, the ambient light and the cameraman's ability to capture a captivating subject, an interesting moment or an exciting scene. Several breathtaking and award-winning pictures and movies do have technical defects, but these are of no importance compared to the other outstanding properties. One who has been a perfectionist in photography is [URL='https://en.wikipedia.org/wiki/Ansel_Adams']Ansel Adams[/URL]. You can't imagine what he would have shown us if HD camera drones had already been invented in his day ...
