Either I’m not looking at it right or my iPhone 11 Pro Max doesn’t use deep fusion. What am I missing before and after shots I took do not show any difference whatsoever. How does one tell when we are deep fusion-ning?

Not that you'll notice a massive difference, make sure photos capture outside the frame is off in camera settings for it to work.

The way I can tell the differences is take a picture and quickly go to preview it and you can see it slightly change.

I've been trying to figure this one out. From what I've been reading the Deep Fusion feature doubles the size of the image file and it doesn't work if Photo Capture Outside the Frame is turned on so I've tried photos a couple of times with that setting on and off to compare. What's confusing me is the image file size is doubled for the shots where the capture outside the frame setting is on which seems to be the opposite of what I expected.

What about the format? What should we set it to? Most efficient or compatible?

I have one question about deep fusion and the iPhone 11: since there is no telephoto lens on the iPhone 11, and since deep Fusion is using different lenses and then computation in the back end, would deep fusion works better with the iPhone 11 pro or would it be the same between the iPhone 11 and iPhone 11 pro? I am a bit confuse if their is any difference between those 2 phones using deep fusion. Thx.

Seriously, Apple needs to publish some kind of user guide for the various new 11 Pro camera features, especially since some will block others. Not bitching, just want to be able to use this excellent hardware.

(Here's the bitching: Since it doesn't work as a phone, we might as well be able to learn how to use it as a camera. :mad: )
 

now i see it

I wouldn't fret over it. Obviously it's not a big change. It's just another computational algorithm added to the others that already existed. Marketing this time decided to come up with a catchy buzz word cuz that what marketing does.

Alright I am responding to myself after having red this interesting explanation from the Verge:

« But in the background, Deep Fusion is doing quite a lot of work and operating much differently than Smart HDR. Here’s the basic breakdown:
  1. By the time you press the shutter button, the camera has already grabbed four frames at a fast shutter speed to freeze motion in the shot and four standard frames. When you press the shutter it grabs one longer-exposure shot to capture detail.
  2. Those three regular shots and long-exposure shot are merged into what Apple calls a “synthetic long.” This is a major difference from Smart HDR.
  3. Deep Fusion picks the short-exposure image with the most detail and merges it with the synthetic long exposure. Unlike Smart HDR, Deep Fusion merges these two frames, not more — although the synthetic long is already made of four previously-merged frames. All the component frames are also processed for noise differently than Smart HDR, in a way that’s better for Deep Fusion.
  4. The images are run through four detail processing steps, pixel by pixel, each tailored to increasing amounts of detail — the sky and walls are in the lowest band, while skin, hair, fabrics, and so on are the highest level. This generates a series of weightings for how to blend the two images — taking detail from one and tone, color, and luminance from the other.
  5. The final image is generated. »

So basically this is all computation and either the iPhone 11 or iPhone 11 pro would work as the same with producing the same pic quality.

The only difference I have noted is that deep fusion can be used also from the telephoto lens when used for a shot so nothing new here.

Unfortunately the Ultrawide Lens can‘t use deep fusion but only Smart HDR.

If this is true, if Capture outside the frame needs to be turned off in order to activate Deep Fusion, I'd say most of the iPhone 11 owners wouldn't know about this for sure.
And it's such a shame since Capture outside the frame is automatically turned on by default if I'm not mistaken.

By default this was turn off outside of the box (in my case, iPhone 11).

How come the picture on the left, the colors look way better!?

High Efficiency will give you better colors.

Agreed 100%, did you write to Apple? I did, we need more people! Email them or Tell them on twitter.

I agree. I am a "fan boy", but not that much of a fan boy to know all of the ins and outs of different software, especially with the camera. IMO, from what I have seen about deep fusion, the change/difference isn't that significant to do cartwheels over.

I am a little frustrated ... i am trying to shoot a deep fusion photo without success... I tried many kind of lightness but nothing.
If I remember, the deep fusion creates a very bigger file about 10 mb versus 2mb normal photo so I undestrand there are a normal photo, I wish the option to activate/deactivate Deep Fusion like portrait... if portrait doesn't work the focus aren't yellow :mad:

Feels like "bad" marketing? If you have what is pretty widely regarded as the market-leading phone camera, you'd think they'd want to make sure people really know how great it is and can get great results.

Can you elaborate more on this please? any sources or experiences?
There is some decent discussion on it in this thread.

He means that the High efficiency options is the new format compression for image like jpeg created by Apple.
This format create a file more compressed but with bigger quality than jpeg, more flexible because you can have more image in the same file and animated image...

I'm finding it very difficult to tell the difference between a normal and Deep Fusion photo using my iPhone 11 screen, but on a Retina MacBook Pro the difference can be obvious and impressive. I'm forcing the camera to take non-Deep Fusion photos for comparison by enabling "Photos Capture Outside the Frame".

Looking through the EXIF in Preview the only difference I've noticed is that a normal photo has "Flash: Auto, Did not fire" while a Deep Fusion photo has "Flash: No flash function".

Surprisingly, in my limited testing so far the Deep Fusion HEIC files are smaller.
