I tried using the camera application 'Halide' that enables macro shooting even on iPhones other than iPhone 13 Pro

The iPhone 13 Pro can take

macro shots of objects as short as 2 cm with the built-in ultra-wide-angle lens and autofocus system. The camera app 'Halide ' performs such macro photography on iPhone 8 or later devices in a pseudo manner and finishes the photo vividly.

'Halide Mark II-Professional Camera' on the App Store

Halide is available on iPhone 8 and later devices. To install, first go to the Halide page on the App Store and tap the download icon.

When you open Halide, the following screen will be displayed and the tutorial will start, so swipe left to proceed.

Halide can be used with a monthly subscription of 350 yen, an annual subscription of 1300 yen, or a purchase of 6100 yen. This time we will start with a 7-day free trial, so tap 'Start free trial and register for subscription'.

Tap 'Subscribe'.

After registration, you will be asked for access to each function, so tap 'Continue'.

Tap 'OK' to access the camera.

To access photos, tap 'Allow access to all photos'.

Tap 'Don't allow' for location information.

Halide's home screen looks like this. To use macro mode, first tap 'AF' at the bottom left.

Then tap the tulip mark at the bottom left ...

Tap 'Continue' to start macro mode.

When Halide enters macro mode, Halide switches the lens used for shooting to the lens on the device that has the shortest focal length to the subject and focuses on it. Halide is different from the normal iPhone camera application, and it is designed to focus only on the closest object. Halide also uses Apple's

neural engine to process the image into a finer image. However, Halide does not come into focus when approaching the subject like the iPhone 13 Pro. The following is the state when the subject is brought close to the point where it is in focus at 2x magnification.

If you use the iPhone 13 Pro, you can get very close to the subject as shown in the image below.

So, I compared the photos taken in Halide's macro mode with those taken with Apple's genuine camera app. The photos shown below are taken with the iPhone 12 Pro using Halide / Macro mode (left) and Apple's genuine camera app (right). The photos lined up as examples are only resized.

Next, I took a picture of the flowers. Similarly, the left is Halide's macro mode, and the right is the camera app. This time, Halide was able to take an image with clearer details.

Next, I took a picture of the tip of a mechanical pencil. Halide was able to shoot slightly more finely.

If you use the iPhone 13 Pro, you can shoot at such a distance.

To check the file format to save, tap the setting button ...

Tap 'Capture'.

In the initial state, 'PRORAW +' is selected, and the captured image is saved in ProRAW format and HEIC file. If you set 'Compatibility priority' at the bottom of the screen, you can also save in RAW format and JPEG files.

Halide can make short-range shooting more vivid than a normal camera app. However, when using iPhone 8 at the time of review, the application crashed because the image could not be saved, and with iPhone 12, the image could not be saved unless the file format to save was changed. ..
