Deep Fusion demo: before and after

Deep Fusion demo: before and after
The latest iOS 13.2 software update is here and it brings one of the most anticipated new features to the iPhone 11 series: Deep Fusion.

Deep Fusion is a new computational photography technique that improves the looks of photos and it's only possible thanks to the power of the Apple A13 chip in the latest iPhones (so it is not coming to older iPhones). What it does is capture a total of 9 images: four photos before you even press the shutter key along with four secondary images, plus one long-exposure photos once you press the shutter button. After that, the A13 chip analyzes all the pictures and extracts more detail out of them, a process Apple summarizes as "computational photography mad science."

And it sure sounds cool, but can you really see the difference in real life and is it the game-changer Apple paints it to be?


 
Let's take a look at the pictures:





Clearly, the differences are not huge and if you are looking at the photos on your phone, chances are you are not seeing any differences at all.

The truth is that Deep Fusion does bring a change, but it is a thing that you will truly appreciate only if look at the photos up and close.

Here at the office, we have 22-inch monitors, and we did a quick blind tests with a few Deep Fusion photos, and on such a big screen, regular people were able to spot a difference easily, describing the Deep Fusion photos as sharper and more detailed.

To illustrate those differences, we have a few crops where you can notice the following benefits:

A. you get a lot sharper photos
B. details like sweaters, furry items, or strands of hair look more pronounced and arguably, better

Overall, images look a bit more granular and contrasted, and we like this look:


However, the added detail and sharpness comes with one downside and it is that pictures with Deep Fusion have a bit more noise in them, especially when you have a spot of the same color. Take a look at a few crops right below to see how the noise is way more noticeable when Deep Fusion is enabled:


Conclusion


At the end of the day, Deep Fusion is here and it works quietly behind the scenes to bring you better photos with sharper detail and better contrast at the expense of slightly more noise. It's not the game-changer that you might think it is and the difference is not really noticeable when you look at the photos on the small screen of your phone. However, if you take a look at the pictures on a bigger screen, you will be able to see an improvement, so much so that images before Deep Fusion would appear to lack in detail and be a bit too soft.

Don't forget that while you don't have a switch to easily turn the feature on and off, you can go into Settings, then Camera, and under the Composition tab, you have the option "Photos Capture Outside the Frame". Deep Fusion will work only if this feature is disabled, so if you don't like the added sharpness with Deep Fusion you can simply do the opposite and enable this toggle in settings.

Stronger hdr only. I thought it was oversampling.

It's like the Super Resolution algorithm found in Google and Huawei phones Decent improvement, but nothing new and no where near a game changer like some people thought

Qualcomm introduced oversampling a few years ago and than came portrait photos and everyone forgot about it.

This year's iPhones, especially iPhone 11, are looking great.

Watching these with my iPad. The difference in details are really big knowing how good the regular photo already is. Biggest difference is happening in the woman face photo, It’s so much better with deepfusion, especially how those eyes are really shining and coming out from the photo

Her face was bit out of focus in regular mode. The men faces are not.

Is it just me, or the pre-deep fusion photos look intentionally out of focus?

That’s just the effect your brain does because deep fusion is so much sharper than what you got used to. Exact same effect here in pro photographer testhttps://youtu.be/JVamB9Zu3yQ

It’s not out of focus, that’s what deep fusion does, it almost make it look like it is, because deep fusion photo is so sharp and detailed. Here’s video from pro photographer testing deep fusion, exactly same results, big improvements in face photoshttps://youtu.be/JVamB9Zu3yQ

Nice try but IMHO the pre-deep fusion photos are better especially if view on the phones display. Cant fault the developers for trying something new thought its the only way to keep improving upon what you already have.

If you can't see the difference on a phone why did they make it for a phone then ?

Because you might transfer the photos to a computer, or a tablet, or print them, I guess?

When was yhe last time you transferred a photo to laptop and printed them? I don't want to throw numbers but majority of photos taken on a phone end up in social media. I normally never transfer photos from my phone even for editing in lightroom as phone sensors are no where near as good as DSLR. My DSLR pics are used for printing but photos from phone end up on Insta

If that's the case, then we should stick with 720 video recording. I for myself transfer all my pictures to my pc, and I frequently share them on my 65" TV screen.

Is it because your phone has a 720p screen?

I see a little bit of colring difference and than a little bit more sharpness in the last 3 images.

I don't notice much difference with sharpness but I think photos from deepfusion has better dynamic range

"..the difference is not really noticeable when you look at the photos on the small screen of your phone. However, if you take a look at the pictures on a bigger screen.." UTTER NONSENSE. There's this thing called ZOOMING

What is funny (and I own an iPhone 11 Pro Max) one of the criticisms of the Pixel was that it was too realistic and sharp in photos of faces, now it is a good thing. As consumers apparently we want what apple pushes????? Seriously it’s good, not ground breaking. Your turn Google push the envelop a little further.

Sounds like you don’t understand the subject. Pixel phones got criticised by oversharpening photos making them look fake not realistic, for example with pixel portrait it makes portraits look like cardboard, realistic is completely different thing, what deep fusion does it makes photos sharper and more detailed from every part of the photo while looking realistic and natural atleast based on what i’ve seen so far Look this and you propably get the idea about pixelhttps://ksassets.timeincuk.net/wp/uploads/sites/54/2018/10/Selfies2.png the problem with the pixel is very sharp edges. And way too punchy photo it doesn’t look natural at all. That’s what the subject Is what you are talking about.

No, I have read many reviewers saying that they were too realistic showing all flaws. These photos are ultra realistic, where others use a filter of some sort to soften blemishes... Samsung was super soft, iPhone lies in the middle, and pixel provide images that people did not want to see because it showed what was there... you have wrinkles, you have small craters on your face, you have fine hairs on your cheeks, pimples and bumps. Lost at the difference in these very photos and you can see the smoothing that had been accomplished afore

"No, I have read many reviewers saying that they were too realistic showing all flaws." Really? i haven't see any, I even just checked randomly 5 reviews and none said anything even related to that.

The differences are noticeable, but not overwhelmingly noticeable...that’s what makes the effect so good. A simply awesome job on this years cameras Apple. In 2020, make this kind of effort with the overall feature set.

An improvement is an improvement. Not the game changer a couple of ifans here made it out to be though.
