Why is there pink noise in water reflections?

I keep noticing this pinkish noise in the reflections on water. It’s pretty annoying, and I don’t know what’s causing it. I’m already using ND filters, but it doesn’t seem to help. Would a polarizer fix this? Or is there something else I should try?

That looks like chromatic aberration. It happens because of the contrast between bright highlights and dark shadows.

A polarizer could help. What camera or drone are you using? It really looks like chromatic aberration, which happens when the lens glass isn’t great. Hard to tell exactly because forum uploads compress images a lot. Does this show up more in the raw images or just the processed JPEGs?

Edit: Quick fix is to desaturate the magenta in Photoshop, Lightroom, or any editor you like.

I’ve tried it on both a Mini 4 Pro and Air 3S, and it’s the same with both. It’s visible in both raw and JPEG images, but honestly, it stands out more in raw. I’ll try your tip in Lightroom—thanks!

This looks amazing, though.

Thanks for all the tips! Like some of you said, it’s chromatic aberration causing fringing. I managed to fix it in Lightroom using the ‘Remove CA’ and ‘Defringe’ options.

Could be moiré from aliasing, especially since many modern cameras skip anti-alias filters. A quick fix would be to target magentas and desaturate them. Lightroom and other editors also have a tool specifically for moiré removal. If it’s a raw image, try clicking the ‘Remove Chromatic Aberration’ option.

@Quinn
Yeah, it’s chromatic aliasing from the Bayer pattern. The optical low-pass filter isn’t strong enough to cancel it out.

It could just be how light sparkles on water. It’s something you’d see with your eyes, especially during golden hour.

Was the surface rough at the time? It looks like tiny waves caused by wind.
