Another moire question...

[michaelhames]

I am asking for your input at this point. Here are a couple of examples from a job this weekend. I have resorted to taking my old Phantom 4 whenever I have any type of metal building to photograph since the images out of the Air3S are unusable.. I thought I would be safer with this shingled structure but as you can see the moire is out of control. Sometimes I have to deliver raw images and I just hate it because they look terrible.

I have tried everything I know.. I am shooting at a low ISO (100-200) - I have images from all kinds of different angles that still have the effect. I am shooting in the 12MP mode because I have found no use for the 50MP.

Is it possible that my drone is just defective? I am really struggling believing that it can be this bad? I appreciate your input.

Have you tried getting closer?

It's not that the drone's defective.
It's physics.
The array of tiny pixels on the drone's sensor and the textured surfaces are interfering with each other.
A sensor with larger pixels (as you've found with the Phantom 4 pro) or changing camera to subject distance is what will help.

What is Moiré and How it Can Ruin Your Photos

Moiré can ruin your photos by adding wavy patterns to them. It occurs when an image is captured with a high-resolution camera that has no low-pass filter.

Getting close would just keep me from getting some shots I need so I guess that wouldn't work. I guess I have been spoiled and never owned a sub 1" sensor drone (other than my mini3 that I didnt use commercially). Bummer

Thanks for the input

Try turning the sharpness down and if worse comes to worse, mask the moire and blur it slightly then add noise or grain back in to match the rest of the image.

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 even the siding planks are aliasing. The higher the resolution the less likelihood of aliasing. If yr shooting low res jpg’s that that could explain it.

What resolution are the images coming at? The pictures that you posted are low resolution PNG files.

12MP should be 4000x3000, and you shouldn't have a moire pattern at the distance that you are shooting from.
