It's free, but you can take professional-grade photos with your smartphone Try the mobile version of "Adobe Lightroom"

Menu screen immediately after starting Lightroom

There is an app that fulfills the selfish request of "I want to take beautiful pictures with my smartphone easily." If you use the “Adobe Lightroom” app that Adobe distributes “basic free” for smartphones, you can use not only shutter speed and ISO sensitivity, but also advanced focus functions and color correction using Adobe AI. [Image] Photos taken and color adjusted on a smartphone "Basic free" is only available when using a smartphone alone. It is necessary to subscribe to the “Photo Plan” that can be used (including tax, the same below) or the “Creative Cloud Complete Plan” for 6248 yen per month. This is recommended if you want to stick to editing in cooperation with the PC and the cloud. This time, I would like to introduce my recommended points for using Lightroom for shooting landscapes and plastic models. The photo was taken with the "iPhone XS", with the lower part facing the right side.

Although it is originally an image editing software, it can also be used for shooting

Lightroom is originally a software that adjusts the color tone and degree of light of a RAW file taken with a camera and outputs (develops) it. . In the smartphone version, in addition to those functions, "Add photo" and "Take photo" buttons are provided. Although the button is arranged like an option, it can be said that this is the main function in the smartphone version. For example, if you try to take a picture of a pet with black hair or a dark color such as dark blue with the standard camera app, the smartphone will judge that it is a dark part and raise the ISO sensitivity or lower the shutter speed to prevent camera shake. more likely to occur. In Lightroom, you can shoot beautifully by setting the necessary parts with "Professional" that allows detailed settings and automating the rest. In addition to this, Lightroom can use 4 types of "AUTO" that automatically performs all shooting, "HDR" that can shoot HDR images, and "depth shooting" that can create a depth map that can only be used on the iPhone. Set the shutter speed and ISO sensitivity and shoot. The faster the shutter speed, the less camera shake, making it easier to shoot. A high ISO makes it possible to shoot dark areas brightly, but if the ISO is too high, noise will appear in the image and sharpness will be lost. Unless you can fix your smartphone on a tripod, it's basically easier to take beautiful pictures with a faster shutter speed and a lower ISO sensitivity. Let's take a look at another UI (user interface). The UI itself is simple, "Exp" is exposure correction, "Sec" is shutter speed, and "ISO" is ISO sensitivity. "WB" is the white balance (color temperature), "[+]" is the focus, and "Initialize" restores all settings. Each slider can be adjusted by swiping anywhere on the screen when selected, and can be initialized by double-tapping the item. The focus can be locked by tapping on the screen, and if you tap for a long time, the focus will be locked and Adobe's AI will emphasize the outline in green. This is a convenient function when you want to bring the camera closer to a small miniature or plastic model to create a blur effect, or when you want to adjust the distance from the camera when shooting multiple people. Note that if the shutter speed is too fast, a flickering phenomenon will occur when shooting under artificial lighting. This is because the LED lights flicker according to the frequency of the electricity flowing through them (50Hz in eastern Japan, 60Hz in western Japan), and can be largely avoided by setting the shutter speed to automatic or 1/100 or 1/120. Color temperature depends on the color of the lighting that hits the subject. It is red under incandescent or daylight fluorescent lighting, and blue under daylight or cloudy weather. In addition to this, you can also change the color tones that you want to appear in the photos you take. It also has a "dropper" function that captures gray and corrects the color temperature. Strictly speaking, it is said to use a painted board, but if you want to set it quickly at the site, it is also a good idea to use a part that looks gray, such as the gray ground that is not asphalt, or unpolished concrete. In addition, you can lock the exposure with the padlock mark, change the color filter with the black and white circle mark, and switch between wide angle and telephoto with the lens mark.
