How to do post-production of mobile phone photo works?

Used to repair the defects of the original photo. Drawing adjustment: the necessary step for each original drawing to come back to life, basically through this step, 90% improvement is completed. Several of these indicators will be explained in detail later. Highlight details: divided into structure and sharpening. Xiaobai needs no special distinction. These two purposes are to make the picture look higher and clearer. Cutting rotation: As the name implies, I don't need to specify. Deformation: I think this is the most popular point in snapseed's mobile phone retouching software. Divided into vertical angle, horizontal angle and rotation. The vertical and horizontal angles here are relative to the screen depth, and even if the shooting angle is not ideal, it can be relatively repaired. The rotation here is different from the rotation upstairs. The picture above is automatic cutting after rotation, while the rotation here is automatic filling, which is crying. Brush: one * * * four kinds of brushes, namely, brightening and dimming, exposure, color temperature and saturation. You just need to draw a few pictures where you want to modify these four indicators. Local: The function is similar to the brush above, except that it is modified in units of points. The radiation range can be selected by sliding with two fingers, and there are three indicators that can be changed, namely brightness, contrast and saturation. It is suggested that in daily picture modification, only the brightness of local underexposure or overexposure should be modified, and it would be strange to modify contrast reading and saturation. Fix: similar to the imitation stamp in PS, but after all, it is a mobile phone retouching, so you can't choose the source of imitation stamp. Small-scale stain repair is more suitable. Halo: With the center of the picture as the origin, the surrounding becomes dark or bright. Except for the occasional slight dark angle adjustment, it is generally not used. These are all filter columns, because filters have a great relationship with people's preferences, so I won't introduce them one by one. Everyone will find what they use most if they try. Individuals can't do without glamour aura and HDR. Please use it with caution when the lens is blurred. Using a mobile phone to retouch a picture is vague and unnatural.
