There is no doubt that mobile phone shooting, mobile end processing image, has become a social platform to share the main path of image sharing. This article will be through a number of cases, and we discussed from the PC side to the mobile end, the image processing experience will be better suited to small screen operation, and different types of image processing applications in the functional design of different emphasis on >>>

The days of "excitedly importing camera photos on the computer, opening PS processing photos, and uploading them to the image community" seem to be getting further and farther away from us. As social platforms move, we are more concerned about sharing photos in a timely and fast manner. Now, the mobile end of the image processing applications, more and more excellent mobile phone hardware performance for image class applications to create more possibilities; a new generation of SLR, memory card with WiFi can be transmitted with the mobile phone, but also to share the picture faster; using the phone's own hardware sensors and some applications of intelligent algorithms, You can even do something that your digital camera can't do on your phone.

One, the effect of a key to achieve

Photoshop, Lightroom and other PC most commonly used professional late software in the functional all-inclusive, each detail adjustment may be different tools, step-by-step implementation, to meet the needs of fine adjustment, processing time is longer. And in the mobile scene to deal with complex tasks, it appears to be overburdened, the need for more simple and efficient way of operation.

The filter in each image app is the preset of adjusting curve, hue, saturation and so on, which is needed in the PC to simplify the operation of one key in the app, and it becomes the most commonly used function in mobile image processing.

Footprint is the integration of the image of the clipping, filters, borders, text and copy functions, a key to the ordinary photos converted to the film wind. Although earlier in the footprint, other applications can also achieve the same effect through multi-step operation, but the footprint of a key in the efficiency and effectiveness of the promotion for it brings the user's explosive growth.

Previous HDR (that is, high dynamic range Image: The final image of a low dynamic range image synthesized using each exposure time relative to the best detail) on the PC requires the image to be light pressure dark, shaded, and tuned to increase the contrast of the midtones to restore more detail in the image. Or to have multiple photos of the same composition in different exposures, each element is selected in the correct part, synthesized in a picture, the process is more complex. and snapseed HDR effect only need one key to complete, in greatly improve efficiency, lower the threshold at the same time, achieve a very good effect.

Second, using intelligent algorithm to reduce manual operation

The most previous portrait beauty app relies more on the manual adjustment of the user, the Facetune need manual grinding, click on the spot acne removing nevus, line Camera (now Aillis) often need to manually locate the nose mouth position. And when the face recognition algorithm has been introduced into a large number of portrait processing app, skin thin face only lesbian pole, or even a key to beauty can be achieved. The advantage of face recognition is particularly noticeable in portrait beauty makeup. Every day p figure hot crazy change makeup, fashion beauty makeup, automatic face recognition facial features positioning, making the material makeup perfect fitting facial features, second speed complete makeup.

The common method used in PC is to sketch the outline of the main body with pen tool or other selection tool, which is limited by the screen size and input device at the mobile end, and can't easily draw the outline of the subject with the finger. In every day of the magic of the map, you only need to smear the main body, the program will automatically according to color information to distinguish the outline of the body, select it.

Anticrop in the new composition, the extension of the use of the image is very simple. Extend the image at least 4 steps on the PC, extend the canvas, select the picture that can be copied or extended, copy it to a blank space, and use a repair tool such as a clone seal to make the copied image perfect with the original image. In Anticrop, the elements that need to replicate the extension are calculated directly, and all you need to do is drag to the boundary you want to extend and fill it.

Third, the use of cell phone sensors, in the shooting to get the trouble of the late

It was hard to achieve a panoramic picture earlier. You need a tripod fixed seat so that you can keep multiple photos at the same level. At the same time need to use the same exposure, white balance, ISO, set a small aperture to make a convenient splicing of the original film. You also need to use PS for late stitching.

The panoramic features of the iphone make the view of the panoramic picture very easy. When shooting the panorama, the phone automatically locks the exposure, depending on the trajectory and speed of your movement to remind you to adjust the level and moving speed, and at the same time to complete the stitching, the whole process takes only a few seconds.

Camera+ records the level information when taking pictures. Later only need to point to straighten, you can automatically complete the level.

Iv. Splitting complex operations

Correction of image distortion in PS is a drag-and-drop operation on Four corners. And in the small size screen, the image of the four corner drag and drop experience and poor, in order to give the image enough to drag space, the screen must be narrowed, make subtle adjustments become very inconvenient. So SKRWT will be split into two latitude, up and down perspective and perspective, drag pole to change the perspective of the degree, only one latitude adjustment, not only easy to control the details, the operation is more convenient.

The same is the adjustment of perspective and deformation of the skew, copy the interaction on the PC, the operation experience greatly compromised.

Five, professional-level app hidden function, the popular app needs full-function exposure

Late app like Snapseed,vscocam is the heart of many photographers, but the threshold for initial contact is higher. Because of the many functions, in order to reduce interference, so that users more focused on the current effect of the adjustment, menu items are often hidden. For example, in Snapseed, when adding an effect, you need to adjust the effect by sliding left and right, sliding up and down to toggle the other peer menu, the interface will not have permanent slider and menu.

To adjust the intensity of the filter in VSCOcam you need to click the selected filter two times before the strength adjustment slider appears. There are few app hide sliders before it, and as this approach is gradually accepted, more and more apps are choosing to hide the slider in such a way that it reduces screen occlusion.

SKRWT, as an image distortion correction app, is aimed at the professional group with stronger obsessive-compulsive disorder. When you are not satisfied with the current level of adjustment, you need to click Pole two times to restore the original value, hide the "restore" button.

By contrast, Aillis (formerly Line camera) is a more popular image processing app. All operations have corresponding buttons on the interface. As shown in the following example, when you click Add Fade, there is a "detailed" button to adjust the degree, after the adjustment, there is a "reset" button to cancel the adjustment. Although there are more interface elements, it is convenient for users to find the operation they need.

Vi. niche apps focus on single point features and social sharing

Do all-inclusive function requires a lot of human input and technology accumulation, small team to be in the functional alignment, laborious, but not necessarily please. The small number of apps that make everyone's eyes bright is focused on a particular feature that will experience and effect unique. To promote, to guide users to do social sharing, or to design products for social sharing. Fused is a focus on exposure (multiple exposures: A photographic application that uses two or more separate exposures, and then overlaps them to form a single photo), features focus, and interface layouts are designed for multiple exposures. The bottom has the choice foreground picture and the background picture's operation area, may choose the foreground picture and the background picture at any time, also may conveniently carry on the reversal. The middle tool can adjust the foreground picture, the background picture separately, the operation logic is clear.

And Enlight is a multi-functional application, the heavy exposure in its operation is called "synthesizer" tool. Enlight interface layout is designed for the late Dantu, in the use of "synthesizer", can only add foreground picture, to make adjustments to the foreground picture, can not modify the background picture, and can not be reversed before and after the picture, so two map to fully integrate will have some difficulties.

Frontback is a social and life-style picture application, the function is very simple. Shoot you with the front camera, the back camera takes a picture of the scene you see, spells a picture, and describes a complete story of what you're doing, which is perfect for sharing.

Summary

Professional digital cameras and digital late in the status of photography although can not be shaken, but in the mobile era, digital image processing changes have quietly occurred, "mobile phone photography" has become a new label. When making mobile image processing app design, we should consider the pursuit of efficiency and sharing in mobile scene more, make full use of platform advantage, and create a more suitable image processing experience.
