Why does my iPhone 12 Pro Max Photo auto adjust exposure of a photo taken with the Camera app?

My iPhone 12 Pro Max (with iOS 14.3) always auto-adjusts the exposure (or contrast) of a photo taken with the original Camera app. It happens when I take a photo then switch to Photo app to view it, the image seems going some background processing for little while and applied with some filter i.e. exposure, vividness, contract changed. I tried disabling all the tweaks in the Camera Settings e.g. Smart HDR, Scene Detection, Lens Correction, even the View Full HDR (under Photos). None of them works, my iPhone always applies auto-adjustment to the photo compared to its original.

How can I disable this ? or could this be some defect with my lens?

iPhone 11 Pro Max

Are you shooting RAW? Apple Pro RAW files need developing after the photo has been taken to create a final image version from the RAW file. And the finished and developed version may look different from the first, basic preview of the RAW file.

Apple ProRAW (iOS 14.3) On iPhone 12 Pro and iPhone 12 Pro Max, you can take photos in Apple ProRAW to edit images with higher levels of creative control. See Take Apple ProRAW photos.

The "View Full HDR" option shows the full dynamic range of the photo taken, but doesn't change the image. You can easily test this by taking look at the images with any 3rd party iPhone App with viewer function or with the Photos App on Mac.


If you don't see improvement on existing images, I'd suggest to try different Camera settings. I only keep the "Intelligent HDR" function and I switched off "Scene Detection" and "Prioritize Faster Shooting", and with these settings I'm finally happy with the image quality out of the box.

For my issue with the 1-3 second countdown (super annoying), the problem was Night Mode coming on automatically (default setting for my iPhone 12 Pro) which has thankfully been fixed in iOS 15. Night Mode still comes on by default, but you can change settings to turn it off permanently.


In iOS 15:

  • Go to settings
  • Pick camera
  • Pick preserver settings
  • Toggle the Night Mode setting to on

That last bullet point sounds counterintuitive, but it will allow your iPhone camera to keep Night Mode off if you disable it for a shot.


Note that you DO need to complete the process by taking another step: take a photo which triggers the night mode into action, and in the midst of doing so, choose to turn Night Mode off. The big difference with the new iOS 15 is that you can now keep this setting and don’t have to reset it for future photos taken under similar conditions every single time.

I’m facing the same problem, I noticed that today. I thought so it may be due to the "View Full HDR" setting being activated in the Photos app. I’ll try turning it off, but now the existing photos are already changed and there’s no way to revert them to original?

it improved some videos I believe, but made so many photos look dull, the brightness or exposure is changed terribly.

Ok thanks I’ll try that. But something definitely happened. I clicked the images and saw them after coming home. And in a while the photo which was bright became dull and the video which was dull became bright. 1st I thought maybe it’s the screen brightness that is changing, but I sent the pic to my wife’s phone (android) and seems like the image actually changed.
