The most delicate business portrait in the late stage of hyperbolic grinding

Business portrait of the requirements of the work is to strive for excellence, not only in the early filming to give force, post-processing can not relax! At least, it is clear that the late principles of hyperbola and neutral ash are a primer. Pocoer Hidesigner in this topic to share the business portrait of the late process, including hyperbolic grinding, gradient mapping, tone separation and nondestructive sharpening, and other content, interested students do not miss it!

　　Step one: Clean up the glaring flaws in the model's face with a patch brush

Use a patch brush or seal tool to clear bumps and blemishes on your face

　　Step two: Double-curve skin on the face of the model

Hyperbolic grinding Skin: Select the high light and shadow area of the screen skin respectively, and use the Curve tool to make the exposure adjustment.

　　The second point: the principle of hyperbola grinding

The core principle of hyperbolic grinding is to use the brightening curve and the pressure-dark curve to highlight the uneven skin area in the darkened picture. The first thing to mention is the concept of the observer.

An observer is a tool that does not affect the final image quality and is used only to observe image features. Add a gradient map, black and white, and curve adjustment layers on the image to form a simple observer. The role of the observer is to maximize the characteristics of the image, even if the parameters of the extreme point does not affect the final quality. We can see the image below the surface of the grinding camera, which highlights the uneven appearance of the skin on the screen.

Found these uneven color of the place, we on the highlight curve through the mask to the original dark spots of the spot adjustment of 1.1 points to brighten; in the dark side of the curve is also the same operation, will be too bright place to press dark. The 1.1-point wipe mask is really time-consuming.

　　Step three: Adjust the overall exposure of the picture with the curve

　　Fourth Step: Repair the obvious defect of the arm skin

　　Fifth step: The use of neutral gray layer to repair the details of the screen

In the superposition or soft light mode, neutral gray layer can not affect the original image quality of the scene to adjust the brightness of the local area, and other details, the superposition of soft light mode will be neutral ash itself, the characteristics of the elimination of only layer changes to the operation.

To use a neutral gray layer:

1. Create a new layer and fill the #808080 with color.

2. Set the layer blending mode to soft light or overlay.

3. In neutral gray layer to reduce light, deepen or brush operation, the results of the operation directly reflected in the original image, at this time can directly see the original image, for the region according to the need for adjustment can be.

　Step sixth: Tonal separation with gradient mappings

A gradient map makes it easy to map the pixel area of a certain brightness to the specified color. According to the following figure settings can make the gradient map results appear "dark purple, bright orange" law. The use of color fusion mode will be a bright part of the screen to restore, the scene will leave the dark side of the purple hue, and the face of the skin is bright orange, so that the color separation. Finally adjust the opacity to control the degree of color.

Use light to adjust the screen exposure to make the light softer and brighter
