You may know that intermittent rashes are always invisible in the presence of medical credentials.

Years ago I became suspicious of my Samsung Android device when I couldn't produce a reliable likeness of an allergy induced rash. No matter how I lit things, the photos were always "nicer" than what my eyes recorded live.

The incentives here are clear enough - people will prefer a phone whose camera gives them an impression of better skin, especially when the applied differences are extremely subtle and don't scream airbrush. If brand-x were the only one to allow "real skin" into the gallery viewer, people and photos would soon be decried as showing 'x-skin', which would be considered gross. Heaven help you if you ever managed to get close to a mirror or another human.

To this day I do not know whether it was my imagination or whether some inline processing effectively does or did perform micro airbrushing on things like this.

Whatever did or does happen, the incentive is evergreen - media capture must flatter the expectations of its authors, without getting caught in its sycophancy. All the while, capacity improves steadily.



iOS added a camera mode for medical photos that extra doesn't do that.

To disambiguate, this is not meant as “added a mode to the stock Camera app”, but rather “added a mode to the camera API that iOS developers can use”.


That's so annoying it's not stock.

I always have to get a very bright flashlight to make rashes show in a photo and then the rest of the body looks discolored as well but at least I have something to share remotely :/


Huh wonder which camera apps enable use of this API?


This is one:

This is VERY interesting and I am glad you posted this, as it is my first time coming across this.


Thank you for sharing. Seems to validate my suspicions!


It's not really something to be suspicious of. Cameras just don't know what colors things "actually" are, mostly because they don't know what color the lighting is. Auto exposure/auto white balance erases color casts or unusual skin colors.

You can put a color calibration card in the picture to achieve a similar effect, but it's not as predictable.


I've had problems like this before, but I always attributed it to auto white balance. That great ruiner of sunset photos the world over.


I remember when they did this to pictures of the moon: https://arstechnica.com/gadgets/2023/03/samsung-says-it-adds...
