Hi all, I did post this in the iPhone 14 Pro pics thread but felt it better to have its own, I have removed the post from the photos thread. Please see below…

Anyone else tried ProRAW at night without nightmode on (so you get a 48mp raw pic), even though I wouldn’t recommend this setting try it and look at the dark areas, do you see square outlines/sections in the photograph?

I have ramped up the contrast on the pics below to show the issue, so it looks worse here but I could still make out the blocks on the unedited pic.

If it’s just my 14 Pro 256Gb I will exchange it at Apple Birmingham once they are available for exchange, I’m hoping it’s not a wide spread issue.

Note: this is only visible when shooting ProRAW and nightmode disabled.

Not normal…

This is a 48mp ProRaw photo (no night mode) and it shows no weird effects.

I haven’t seen this on mine yet, I also haven’t taken ProRAW shots in low light yet either. If you have the Halide app, you can shoot 48mp photos in jpeg without ProRAW. Halide also offers ProRAW as well and the quality is the same as the default camera. I’ll have to test mine out and post the results…

If you turn the contrast down you can see the blocks in the top corners too in this pic, not as bad as mine but they are there, here’s a crop from the left top, probably not as noticeable as you have lots of light in the pic.

Zoom into the top left.

I asked 2 friends to see if theirs did this in the same sort of lighting, one a 14 Pro max and another 14 Pro, both of theirs do this also, I’m assuming it’s a more wide spread issue.

Adam.
 
Can you provide more details on what settings you're using?

ProRAW on, night mode off, -100 contrast?

48mp ProRAW on, nightmode off, live off etc, make sure there’s little light and plenty dark, or just a dark/black room (no flash), snap the pic, edit in photos and -100 contrast to see this strange stitching effect.
 
Can confirm. Took a photo in a completely dark room with only a single blue LED as lighting source. I see clear stitching at -100 contrast.

Thanks for testing, I hope apple sort this issue that I’m assuming is a software issue.
 
I don’t see that issue with mine. Even with the highest ISO of 12,500. Just noise and a few hot pixels. If the next update of iOS doesn’t fix it, then I’d call apple support and explain. They will probably suggest taking it to an Apple Store (if there is one nearby) and or send you a new unit.

I will exchange it at the Birmingham Apple Store once units become more available.

The squares are JPG compression artefacts. It's normal on all JPGs but most noticeable with high compression and images which are dark and lacking in detail. Are the squares in the ProRAW DNG image as well? Your image is only 1MB so is very heavily compressed.
Are you sure the image is 48MP? I thought that the iPhone automatically selected 12MP in low light.

It’s the forum that compresses the image, yes it’s full ProRAW 48mp that this happens to, I can replicate it over and over in a pitch black room.

It does select night mode in low light but if you disable night mode and snap a ProRAW pic you get 48mp, then you see this issue when you - the contrast in the Photos app on that pic.
 
Here’s a video of me replicating it just using my hand to cover the lens to make it dark.

As you can see it’s a full 48mp RAW photo, night mode disabled.
 
Had a „Genius Bar“ appointment today. They said the squares/lines/tiles-effect has its cause in the limitations of the the sensor.

Did they say if all the 14 Pro’s suffer this?

I guess we just don’t shoot in very dark places in RAW without nightmode on.

Thanks

They it’s the first time they were seeing this… So the sensor-answer was just a guess.
I don’t blame them. They were clueless themselves.
I’m going to report the issue via apple-feedback and keeping my phone..
Let’s see what happens.
