The iPhone 7plus Portrait mode: ingenious or rubbish?
Since a couple of month the iPhone 7plus is out, and one very special feature is this portrait mode. I got it very early. And had to wait until the release of the portrait mode. It has some ups and downs - and it is still in a beta phase....
Lets start with some technical considerations.
Technically it is a pretty remarkable approach:
Quite ingenious approach. The simulation of a larger sensor with a smaller one.
But what is the portrait mode like? Well - I took my lens with the nicest bokeh I own on a Full Frame camera. I tried to make the same shot with the iPhone and my Canon EOS 5DMk IV with the Zeiss Milvus 50 mm f1.4 (I know pretty unfair... to some extend...)
Above you see the result: Matching this I would say: Well the iPhone ends up with a f5.6-ish aperture... For full frame: pretty slow... But keep in mind... This is full frame... In reality this means - to name it with typical lenses used...:
Using the Portrait mode I had some strange findings - just where things went wrong. And it seems to be still unsolved:
The photo was taken of a bitter. Look close to the gutter you find some weird stuff. The algorithm did not find the steel and mixed the whole image up...
This image shows some strange behavior around the leafs. It really does not look great....
And a bit even more weird is the missing glass. Which is clearly there. But not in the image above...
Sometimes it works pretty nice, and I wanted to show some examples below
This image shows where the portrait mode is working quite properly. Especially if you do not intend to pixel peep...
Also in this image it works pretty nicely
Another nice one....
This is also one of the nice images taken last autumn...
The portrait mode of the iPhone 7 plus is a nice feature to simulate some (!) out of focus blur. It is nice especially to share these images on social media. But in the present status of this technology please do not print them largely...
And be careful. please check the images before sharing. Otherwise you might share rubbish. Like the wine without glass....
And keep in mind: it does not replace the bokehliciousness of good glass on good cameras. This remains to be a totally different story!
The photos were shot with the iPhone 7 plus. The comparable photos were shot with a 5DMkIV and the Zeiss Milvus 50mm f 1.4.
