Cam App - Iphone 15 Pro Max FALSE COLOUR issue

Hi guys,

Been using this device for a week or so now. Looking at contrast ratios and struggling without a light meter. So using false colour.

The issue I have is that the darker colours aren't being represented by dark blues and purples, the colour is green. This is confusing as the darker skin tones should be green, so this is getting mixed with what should be blue and purple

I have attached an image for reference. In total darkness, the colour shows as green.



I have experimented with exposure settings, shutter speed/angle, ISO, aputure is fixed but I have tried other lenses. I have also tried with a rec709 LUT on when in Apple Log mode. I get the same result in colour representation.

I have also tried restarting the phone and the app. The highlights rep of yellows and reds work fine.

Do you know what I could be doing wrong here, or how to solve this?

Thanks

TL;DR - my false colours are showing all in green in the darks and blacks, where it should be blue and purple.

May I suggest to give the CinemaP3 app a try? It has much better measuring instruments, including false color. And it's not a subscription.
