iPhone 7 Plus Portrait Mode (β) Edition

The iPhone 7 Plus rear camera has a 4mm (35mm equivalent 28mm) f/1.8 wide (with optical image stabilization) and a 7mm (35mm equivalent 57mm) f/2.8 tele (optical image stabilization). None), with two cameras. The standard camera app has a [x1] display on the screen, and by touching it, you can switch between x1 and x2 (however, depending on the scene, x2 may also use x1 digital zoom). Many camera apps also support switching between wide and tele with a little delay.

This alone makes the image different from the conventional iPhone, but with iOS 10.1, it is treated as a beta version, but the long-awaited "portrait mode" that can blur the background has been added to the standard camera app. . Seeing is believing, so I would like to see a comparison example.

What do you think? You can see that the background is blurred when portrait mode is on. You can turn ON/OFF to leave a normal photo without blurring in the settings, and since it is a comparison with the photo obtained when it is turned on, it will be exactly the same cut. This picture was absolutely impossible with the conventional iPhone, and it is epoch-making. Below are 12 JPEG examples taken in full auto, without exposure compensation, and without color cast.

When switching to portrait mode, it automatically switches to x2 (x1 cannot be used), and the words [Depth of field effect] are displayed on the screen. However, a certain distance is required, and if it is too close, it will guide you to "Please move away." If it is too far, it will guide you to "Please place the subject within 240 cm." Need more brightness." is displayed. It seems that the fact that there is no optical image stabilization on the tele side also affects the fact that you can't shoot in dark places.

Unrelated to this condition, in the cases where it was difficult to turn on, there were many cases where a rectangular billboard-like image was included in the composition. In the example, the cafe table (S09.jpg) corresponds to this, and I posted one when it happened to be turned on. Other than that, I was able to take great shots, and I didn't feel much of a difference from shooting normally on the wide side. The degree of bokeh also differs depending on the distance to the background, and it is relatively natural and gives a good impression (bokeh is fixed and strength cannot be adjusted).

However, in terms of snapping, x2's 35mm equivalent of 57mm is a difficult focal length to handle. It is not suitable for composing a drawing of a building, etc., and is generally used for taking close-ups of something. However, even if I stroll around the city, I can't find such a subject, and as a result, the distance I walk becomes longer (laughs).
