Does anyone know photoshop? Preferably a digital engineer.

There are many photo retouching softwares, and photoshop CS2 is the most powerful one now. But many digital retouchers don't know where to start when retouching.

In fact, there are certain rules for film retouching. As long as you follow the following order, you can repair a digital photo of the studio. This is the film retouching process of a large domestic studio.

Let's do an in-depth study here.

First, the adjustment of the curve

Generally, trimming photos begins with curve adjustment. Press Ctrl+M to open the curve and adjust the digital photo. You can hold down Alt and click the diagonal line in the box with the mouse.

The trimmed area of ten squares becomes one hundred squares. Click the zoom button in the lower right corner with the mouse to enlarge the curve adjustment area, so that we can trim the picture more professionally.

When adjusting the photo curve, you must choose the adjustment point correctly. Portrait photos generally focus on people's faces, and try not to choose places with bright or dark faces.

You can hold down the Ctrl key, use the mouse to select a suitable position on a person's face, and then a point will be left on the curve. Just use the up and down keys on the keyboard to adjust the curve upwards.

The photo will be brighter, and it will be darker if you turn it down. In this way, we can easily control the adjustment of the curve. In fact, there are many places where digital photography can be directly linked with traditional photography.

It is very useful to apply Adams's "zone exposure method" to the trimming of curves to tones.

We can divide the curve into ten areas:

Low-key zone: Zone 0, Zone I, Zone II and Zone III.

Middle zone: Zone 4, Zone 5 and Zone 6.

High-profile areas: seven areas, eight areas, nine areas and ten areas.

The shadow theme in different areas can correspond to the gradient vertical bar on the left, and the point of adjusting the curve is to adjust the corresponding picture. Send it to section seven like a digital photo-

Eight areas have normal skin color, rich layers and strong three-dimensional sense, which is suitable for portrait photography. If transferred to the eighth district-ninth district, it will look brighter and suitable for commercial wedding photography.

In this way, even if our monitor is not very good. You can also adjust the tone of the photo very accurately. You can also reverse the photo by adjusting the area line.

Poor, using the mouse to pull down on the diagonal from the second area to the third area can improve the contrast of the photo and reduce the haze of the photo.

Compare a photo first!

Changes before and after the chart.

Look at the steps we follow. After opening the picture, look for orderly light spots first.

Then there is adjustment!

Step 2: Adjust the color scale.

You can adjust the tone of the photo by moving the input button, but you can't make the photo too bright at once, otherwise it will be difficult to trim it later.

This digital photo is underexposed and the tone is dark. You can move the input highlight button to the left to brighten the photo, but don't move it too much. If it exceeds the position indicated by the arrow,

The highlights of that photo will lose their layers.

This is the adjusted histogram, and you can see the obvious changes.

In fact, there are many ways to adjust the color scale, such as using dark and light straws, which are introduced in the tutorial of our forum (especially when applied to black and white film).

Or the tone of the middle gray level has also been introduced, but this is not easy to control, and this method is not recommended without a certain technical level.

Third, the adjustment of color.

After retouching a photo, you must adjust the tone of the photo to a suitable program before you can start to adjust the color, because in RGB color mode, brightness information and color information are intertwined, and adjusting the brightness of the photo will subtly affect the color of the photo. If the color difference of a photo is large, you can use color balance to adjust the color of the photo, because hue/saturation is deeply adjusted, because hue/saturation and saturation have more adjustment options, which is very flexible, and it is also very convenient to adjust the color to monochrome black and white. This is the change before and after the adjustment. Sometimes we often want a certain style, so hue/saturation is used a lot!

Experienced digital artists often look at the facial color information of digital film characters when adjusting photos, such as RGB and CMYK or HSB(H hue S: saturation B: brightness).

Can be displayed. On a person's face, the value of K is generally 0, the value of C is small, and the values of M and Y are close. A big M means there are more products in the photo, and a big Y means the photo is more yellow.

This step is to locate the color of the picture, adjust the position in the image menu/color balance (ctrl+B), and locate the color by adjusting the slider.

If your photo sense is not strong, it is best to use it with the information panel.

Fifth, repair the image.

This step is to clean up the excess dirty spots in the image, including fine lines and crow's feet on the face, and then stamp it with the tool panel. The stamp tool should be used in conjunction with the Alt key. It's time to trim your face.

The pressure value should not be too large, the transparency should be controlled below 30%, and the writing point should not be too small, preferably slightly larger. The hardness value of brushes with imaginary edges is 0. Smooth it.

Then use the deepening tool to emphasize the eyes and eyebrows, the exposure is controlled below 20, and the range is selected in the middle tone.

Sixth, sharpen the image.

Chapter may affect the clarity and texture sharpening of the image during processing. In order to make the restored image more textured, we adopt a sharpening method: first use the selection tool.

Create a selection area on the face, and then add a feathering value to the face. Feathering is available in the selection menu, or you can use CTRL+ALT+D, and the value can be selected around 30. (For the record,

Our picture is online, not a real digital movie, so don't be too big. Then select Filter menu/Sharpen //USM Sharpen, and the radius is suggested to be between 1.5-2.0 pixels.

If the number is below 60% and the threshold is 0, click OK, and the face will be more textured after repair.
