i bought the dji air3 s because dji advertised that has 14 dynamic stops.Unfortunatelly i found that the 14 dynamic stop works only at auto mode no at pro mode....This is dissapointed because as a proffesional i fly only with pro mode ....Dji please fix it...

Hi there, thank you for your inquiry. Currently, the 14 stops of dynamic range are achievable for video on Auto mode but not for vertical or slow-motion video.

We'd like you to know that we appreciate your valuable suggestions. We will forward your concern to our related department. All significant suggestions will be implemented after the evaluation of our relevant team. For the latest updates please stay tuned to our DJI official website at ( www.dji.com ). Thank you for your understanding and support.

I dont want to have 14 dynamic range at vertical or slow mode but at pro mode i want to have it at every resolution (4k or 1080)and any frame rate

DJI's advert doesn't make it clear but you only need to enable Auto ISO to achieve the higher dynamic range, otherwise you remain in full control of the exposure.

There is a very good reason to enable both Auto ISO and Auto Shutter Speed (in Pro Mode), you can find more details in my threads https://forum.dji.com/forum.php? ... D938%26typeid%3D938 .

thanks for the info.if i keep only auto iso and keep the shutter speed stable(to archive 180 rule)at pro mode i will have the best dynamic range?

Yes, I understand why you'd want to keep the same shutter speed. The only caveat is to not be too aggressive on pushing the Auto ISO towards 100, because you'll start to lose the high DR advantage even if Auto ISO is enabled if the camera is not allowed to under expose.

There's another problem covered in the thread pertaining detail retention in the shadows, where details are erased due to having no noise. For that reason I enable both Auto ISO and Shutter speed, because whilst the drone does prefer to preserve highlights (thus will be happy to push the shutter speed up high): when light level becomes low enough it will do a good job at both preserving highlights and getting close to the 180-degree shutter.

Both Auto ISO and auto shutter speed impact the image in subtle ways. Enabling Auto ISO always helps recovering a bit of highlights (and sometimes brightens up the shadows), but in certain scenes enabling Auto shutter speed also recover a little bit more highlights.

The ISO and shutter speed values shown in the Fly app also lie sometimes: you'd find that the same values shown in the app will be different compared to what is recorded in the SRT file.

For recent DJI drones, it's a good idea to let the drone figure out the best exposure setting instead of controlling it ourselves for the best image quailty.

I may archive best image quality but how the 180 degree rule?how i will archive the motion blur(for example 50fps 100 shutter)? except if if i have pro mode and i use auto iso...this will work?

Thanks for sharing that information THANOSVSTROM, I really appreciate it.  How much obscurity on the part of DJI...

Yes, it'll work but as I mentioned: we need to be mindful and allow the camera to underexpose by at least 2-3 stops, so instead of targetting ISO 100, it'd be better to target ISO 400-800. So if you are keen on using Auto ISO/manual SS, you should aim to use an ND filter that makes the ISO float around 400-800 instead.

This is quite similar so how other professional video cameras work where ISO 800 is the native ISO. Not sure what the 2nd native ISO of the Air 3S is as it's not advertised, but for example: the Mini 4 Pro's 2nd native ISO is 640.

ND filters is a massive hassle for me so I'd usually just go with auto ISO/SS and add motion blur in post as needed.

what is dynamic stops?

what is dynamic stops?

The term should be 14 stops of dynamic range.  DR is the range of the lightest and darkest tones that an image sensor can capture with minimal detail loss in those areas (highlights and shadows).

so like if the picture is under exposed and looks black or overexposed and white but theres still data?
