Like when I take a picture, I’m used to quickly tapping its preview to see it, on my xs max it loads instantly and looks exactly as I captured it. On my 13 pro however, it looks blurry for 1-2 seconds then it’s processed. This kinda makes it feel like android lol. Is this a bug? Or a hardware issue?

This occurs using any camera lens, whether rear or front.

It’s also odd that even after taking multiple photos, this post processing delay occurs when viewing the photos after they’ve been taken for quite some time, and doesn’t happen in the background as one would think, even with considerable time having passed since taking the photos.

This thread on reddit perfectly showcases what I’m talkin about.

Also this one.

It happens whether ProRaw is enabled of not.
Is this normal?

happens regardless, like with it enabled or disabled.
Odd. ProRAW files are much bigger files to process and handle than the traditional compressed format. Try a restart and/or make sure you are not running low-power mode.

I think that’s normal, happens on my 13 Mini, on my sister’s 11. Maybe has to do with Deep Fusion.
it doesn happen on my old xs max, weird..
this kinda reminds me of the cheap androids that take time to process photos afrer taking them lol

Check your camera settings and maybe post them. There is a "Prioritize Faster Shooting" you might have disabled.

look at the

Really bad photos with iPhone 13 Pro (+Max) Merged​


it’s extensively talked about there
How come not a single reviewer brought forth this issue? This is so ridiculous:/

I have the same issue, it's very odd, I thought it was normal on the 13 but maybe not. Never happened with my 6s

This is Deep Fusion and it was talked about extensively when it was first introduced with the iPhone 11:

“The machine learning process looks at every individual pixel before combining, and it only takes about one second to process everything. Deep Fusion will happen in the background, and you'll never really notice it until you see the images it produces.”

except that I can see it and it doesn’t happen in the background :/

Yeah, I‘m not a huge fan. I remember seeing the Pixel 2 doing this a couple years ago, and I was surprised that no reviewers mentioned it because it seemed annoying. I was thankful the iPhone was instantaneous.

Now the iPhone does it too. 🤦‍♂️ And again, no reviewers mentioned it.

Practically all reviewers mentioned it back when it was introduced over 2 years ago. It’s old news now…

I think some people are getting hung up on semantics.

Deep Fusion absolutely happens in the ”background”. There is a 1-2 second delay between the initial photo you see which has not yet had all 7 pictures stitched together, and once Deep Fusion finishes, the photo is updated so that you have the final computational photography result. Of course you notice the transition. If this happened in the ”foreground”, then there would be a busy cursor or progress indicator giving you feedback.

It happens as fast as possible with the Neural Engine and SIP coprocessor running at full speed.

You have 2 choices in today’s day and age if you use an iPhone 11 or newer. Use the iPhone with Apple’s choice of computational photography decisions, or select another phone if either the 1-2 second delay, or the final result are not appealing.

The thing is, that delay is always present. As in, if I take a photo and go view it later in photos, could be hours later or so, it’d still show up as blurry and all messed up, then in a sec or two it’s fixed. So it doesn’t appear to be happening in the background.

I see. I think I saw this once when I tried to use the Optimize iPhone Storage option in Settings -> Photos. It’s like it kept a scaled down version of the image in the library, but when I selected it, it downloaded the full quality copy from iCloud.

I haven’t seen anything like that again though since I disabled it and selected ”Download and Keep Originals”.

I don’t use icloud for photos, so it’s not that.

It usually only happens in medium light settings to me, and I assume it was Deep Fusion kicking in. Deep Fusion takes a couple of seconds to process the photo, which is why it looks blurry at first. You can also confirm if Deep Fusion is being used if you have the Metapho app, although it doesn’t identify Deep Fusion in ProRAW photos for some reason
