This is an App that specializes in taking long exposure photos. According to the official, after pressing the shutter button, the App will take hundreds of photos in a few seconds, and then use machine learning, artificial intelligence and metal graphics to accelerate the superposition and reconciliation of these photos into gorgeous long-exposure photos.

Most importantly, this App can also erase moving objects in pictures, leaving only static elements. In iPhone8 or newer models, the anti-shake function driven by AI neural engine can further ensure the clarity and sharpness of photos.

Step 2 click

With AI technology, you only need to import pictures, and the App will analyze the content and recommend appropriate filters. Clicking is more suitable for "lazy people" and pursues better results with fewer steps. Click with intelligent scene recognition can not only match the filter, but also automatically adjust the contrast and color saturation for the current scene to solve the problem of how to match the filter and retouching.

3. UOKA has cracks.

UOKA also optimizes photos through scene recognition, but it is one step ahead of clicking the filter. It can intelligently identify and then match the corresponding scene mode while taking photos, which means that AI has already handled it while taking photos. If you don't want to continue retouching, you can send a circle of friends directly, you can take pictures before and after, and you can apply in one step.

Step 4 correct retouching

It is the basic principle of perspective that the near is big and the far is small. Not only the human eye, but also the lens will produce perspective phenomenon. The object under the lens may be narrow at the top and wide at the bottom, or it may expand in the middle. Ordinary rotation operations can't take them away. The functions such as Corr retouching reference line, free transformation and stretching can easily correct lens deformation.

In view of the fact that the tall building is narrow at the top and wide at the bottom, there is no straight picture frame. Using Corr retouching to draw four reference lines in the picture, you can "frame" the tilt and distortion in the picture. For barrel distortion of wide-angle lens and pincushion distortion of telephoto lens, the slider in "telescopic" can be corrected by sliding left and right.

INCH is a new product launched by the team of short video application blockbuster, and fashion photographer Man Chen is of course one of its founders. This is a camera App with very simple functions. The shooting interface imitates Polaroid, and the film is shot directly, eliminating the post-processing process.

The core function is of course the filter, which has the background of Man Chen, and professional photographers are invited to design the filter for it. At present, there are seven filters, including Kobayashi, Duckweed, Ueda Yoshihiko and Broadway. Although there are many filter apps now, Inch still has its own characteristics.
