    Another moire question...

    Lightroom and Photoshop have de-Moiré algorithms, you can even just brush on the algorithm using the mask tool and set the strength, they work very well, this is a common problem with lower res sensors. EDIT - I tried this on yr image and it didn’t work. Are you shooting raw (DNG) or jpgs? I see...

    ONE MAN, ONE MOUNTAIN - Narrated Short Film (6K, DJI MAVIC 4 PRO)

    Well not a criticism but it did look a bit like DJI’s promo video for the M4 Pro, but that’s good, it was well done. I’ve been caught in the woods several times after sunset, not sure I learn from my mistakes.

    ONE MAN, ONE MOUNTAIN - Narrated Short Film (6K, DJI MAVIC 4 PRO)

    Very nice M. Nice use of intelligent flight modes. Fantastic scenery. I can see you were smart enough to head down the mountain in daylight, unlike myself who did a similar hike (not quite as ambitious) but stayed at the top throughout the afternoon, heading down at sunset, only to find myself...

    Need Forum help please...

    I haven't read all the responses but you're doing FreePano with 6x zoom? Why? Surely you’d just use the wide lens (which also has the bigger sensor) and take one photograph (or fewer photographs). I can’t think of a reason to do a panorama with a telephoto lens unless your planning to make a...

    RAW vs JPG - dynamic range difference?

    Just a thought, is it possible the M4 pro jpeg capture is taking advantage of the quad bayer sensor and actually taking a single HDR photograph?

    lost mavic pro seeking guidance

    There are many more knowledgable folks who can help here but at a glance you drove to a dense forest area and started the drone where it could not establish a new home point. A common problem in a dense forest where the drone can’t see sufficient number of satellites. You might find the drone at...

    Bird Hazard deterrent placements on drone

    Birds are pretty smart, I tried to scare pigeons away from my garden with a plastic owl, last time I looked, a pigeon was sat on the plastic owls head. I’ve flown drones since 2012 and often attracted birds, raptors appear from nowhere and circle overhead but I’ve never actually been hit by a...

    Why is this happening?

    Are you using an encrypted browser like DuckDuckGo? I get the same problem with DuckDuck, I think its just preventing downloads to your computer without your permission.

    D Log M (with Auto ISO) Superior to D Log

    auto iso will give you nightmares in post, stick to manual everything. d log m adds compression to highlights and expands shadows so has the potential to produce a better finished job, but from personal experience, working with log in post is not easy. It takes quite a lot of skill, experience...

    Bird Hazard deterrent placements on drone

    Ive flow DJI drones since 2012 and never once been attacked by birds. I’ve seen vultures frequently, fly around in circles above the drone, I’ve had waterfowl zip past, a little close for comfort, I’ve seen hawks look on in curiosity, sea gulls flock around etc etc but never been attacked. If I...

    Overexposure warning, Color assist and D-log question

    I just saw a post on the DJI forum where they point out that Colorassist is only affecting the display on your controller, it has no effect on the clip you download to your computer. It's an effort to reduce the washed out look of D-Log while filming. I just use D-Log and the histogram to adjust...

    Overexposure warning, Color assist and D-log question

    I’m not familiar with colorassist. Does colorassist apply the D-log curve to each colour channel separately? D-log squeezes greater dynamic range out of the signal by pulling down the RHS of the histogram and pushing up the shadow area. But using this requires you to have a good transcoder in...

    Obstacle Avoidance Failed

    I don't have the Air 2 (I have M2 Pro and M3 Classic) but the sensors don't detect small branches or fine wires.
