Try "M-Camera" without shutter sound with noise-covered photos on iPhone (page 1/2) --ITmedia Mobile
When you take a picture of a pet or object with black hair with the standard iPhone camera app, there are many people who have experienced a lot of noise even if the image is magnified. The cause is that the iPhone decides that "the black part is dark!" And sets the ISO sensitivity high. If the ISO sensitivity is high, dark areas can be captured brightly, but noise is generated in the finished image.
The solution is an external camera app distributed on the App Store. The "M camera" introduced this time is basically free, and the upgrade to the "full-featured version" including the use of ultra-wide-angle cameras, HEIC / HEIV format, and deletion of advertisements is 490 yen (tax included). Even if it's free, it's easy enough to use, so it's recommended to install it for the time being.
This time, basically, I will introduce the UI etc. with the bottom of the iPhone on the right side and holding it sideways.
The author's family photographed with an M camera this time.Looks moody because I was pointing the camera while I was sleepingThe basic UI (user interface) is simple, with ultra-wide-angle / wide-angle / telescope switching, photo resolution, aspect ratio, out / in-camera switching, etc. on the left side of the screen. By flicking up and down, you can lock the timer, add GPS information, flash, file format, time stamp, grid display switching, and screen rotation.
Just like a normal camera, you can tap the screen to focus and swipe up or down to switch the exposure compensation, and tap the "1x" mark at the bottom center of the screen to use the optical zoom function. You can finely adjust the zoom magnification in a dial manner by tapping it with the pad of your finger. You can also switch the UI display by tapping the arrow mark under the shutter button.
The orange mark on the right side of the screen is for switching between camera / LIVE Photo / video. In any case, the ISO sensitivity and shutter speed introduced in the next section can be changed, so it is quite easy to use. Also, since there is no shutter sound, it is convenient for shooting scenes where sound is anxious or animals that are sensitive to sound.
In the full-featured version, you can use HEIC / HEVC format, 12-megapixel resolution, burn-in character setting, and ultra-wide-angle / telephoto camera. The resolution of the free version is limited to a maximum of 8 million pixels, so this is a big advantage of the paid version.
It is attractive that "Burn character setting" can be burned like a nostalgic film camera (photo = left). It is also possible to switch to HEIC, which has a smaller file size (photo = right).However, these settings are only available in the full-featured versionThe biggest attraction of M-Camera is that you can set the shutter speed and ISO sensitivity manually. You can adjust the ISO sensitivity and shutter speed (Exposure Time) with "ISO" on the right side of the screen, the focal length with "FOCUS", and the color temperature and tint that changes the color when using lighting such as fluorescent lamps with "WB".
The color temperature can be set automatically if you are not particular about it, and the focus can be easily adjusted by tapping the screen. The problem is that the iPhone adjusts the ISO sensitivity where it thinks it's "dark". If the shutter speed is slow, camera shake is likely to occur, and if the ISO sensitivity is high, grainy noise will be generated in the image. The faster the shutter speed and the lower the ISO sensitivity, the easier it is to take beautiful pictures.
A dog taken with a standard camera app as a trial. The metadata records ISO 640 and a shutter speed of 1/25 second.It looks like it's taken beautifully, but there's noise running around the tip of my ear.Considering that point in the app, the ISO sensitivity and shutter speed can be finely adjusted by tapping the slider and arrow mark. You can change the value finely by sliding the slider up and down, and you can adjust it to a certain value by tapping the arrow mark.
When you move the slider, "AUTO" at the bottom changes to "MANUAL".If you want to return to auto, tap "MANUAL"Let's actually shoot. This time, I will shoot a dog sleeping quietly, but if the shutter speed and ISO sensitivity are set to automatic like a standard camera, it will be shot at 1/25 second, ISO sensitivity around 600. This time, I set the shutter speed to 1/50 second to reduce camera shake and the ISO sensitivity to 320 to reduce noise.
If it is set to the same automatic as the normal camera application, the ISO sensitivity will be set high (image = left). Find the proper balance between ISO sensitivity and shutter speed while tapping the slider and arrow (image = right) A dog actually shot at ISO320 for 1/50 second.There is relatively little noise and the picture is beautiful.Focus can be adjusted by tapping the screen, but the slider is useful when you want to make fine adjustments from there. I often make small plastic models and shoot them, and it is useful because there are many scenes where I want to focus only on one of the plastic models placed in front and behind.
Focused on the front plastic model Focused on the rear plastic model. If necessary, make fine adjustments from here, but this time it was not necessary.Use the "Governor" series of Kotobukiya's kit block series "Hexa Gear" for shooting Copyright (C) KOTOBUKIYA Other interesting functions 1 | 2 Go to the next pageCopyright © ITmedia, Inc.
