Picture analysis

The original film for the film, want to show the figure turned around when the movement of the skirt swing moment, but because the seat is too high, and shutter speed too fast, the final frame of the moment failed to show the intention of shooting, aesthetic.

The idea of adjustment and repair

In order to solve the problem of the original film, we first use the "lens correction" and the "Free transform" tool to change the shooting angle in the later adjustment. Adjusted from overhead to head-up angle, then use the "liquefaction" and "imitation stamp" tool to change the human body shape, modify the character skin, and then apply the "motion blur" tool to adjust the image of the skirt pendulum, so that its dynamic , and then use the black and white tool to adjust the color of the photo.

First, lens correction

The tool is generally used in the construction of the late adjustment, it can well adjust the distortion of the building, for our daily portrait photo adjustment, it can be regarded as a "sharp weapon."

1. Copy the background layer after opening the picture, apply the shortcut "Ctrl+j" and click "Filter" to select the "Lens correction" tool in the Pull-down menu.

2. In the Open Lens correction panel to choose "Custom", so you can according to individual needs of the photo deformation adjustment. Adjust the vertical perspective in transform, drag the slider to the right, change the character's perspective, and note that the picture will change proportionally. After perspective adjustment, drag the slider of the scale option to shrink the picture. By adjusting, reduce the angle of the seat, lengthen the figure.

Tips:

The lens correction tool in the Photoshop filter can be used to handle the perspective and angle of a photo, as well as to handle dark corners and fix color edges.

Many later people will choose a relatively simple and quick method, directly lengthen the legs, so that the characters in the screen feel high. But in fact, direct use of the selection of elongated legs will lead to the wrong perspective, it will look very awkward, so in the long leg to adjust the picture before the perspective of the relationship, so the effect will be a lot of natural.

3. On the basis of the adjustment of perspective, and then slightly lengthen the leg of the model. First move the picture up some, so that the bottom of the picture to leave more than a few blank positions, and then use the "rectangle" tool to do the selection, pay attention to the selection of the people do not choose the hand.

4. The selection is converted to a layer. Use the shortcut key "Ctrl+j" to convert the selection to a layer, and then use the free transform tool to lengthen the character's skirt slightly.

5. Re-composition. Crop the screen and fill the blank area of the background with black.

Ii. liquefaction and modification

The body of the character is liquefied, the skin defects are concealed, the method of adjustment is relatively basic.

1. Use the "imitation stamp" tool to modify the skin of a person to conceal flaws. When decorating, pay attention to the size of the brush and the control of the flow.

2. After the skin and clothing details are repaired, duplicate the layer, apply the "liquefaction" tool to adjust the person's shoulder and arm, the adjusted figure is more slim, the proportion more comfortable.

Third, dynamic Blur

The fuzzy effect of skirt pendulum is made by using this tool. In fact, the principle of motion blur and Gaussian blur some similar, the difference is that dynamic blur is a directional, generally in the photo processing is usually used to express the sense of speed, so that the static screen to produce a sense of movement.

1. Use the "Rectangle" tool to select the skirt part in the screen and copy the layer. When you choose to pay attention to the character hand parts do not choose too many.

2. The skirt pendulum part carries on the dynamic fuzzy processing. Set the blur angle and distance in the motion Blur dialog box and click OK.

3. Add mask, wipe out the screen without ambiguity. Add a mask on the blurred layer to erase the hand and part of the figure, making the blur effect more realistic and natural.

Four, go color and coloring

Seemingly contradictory adjustments are necessary. First of all, the color of the image processing, and then through the color of the whole picture, to achieve uniform color.

1. Use the "Black and white" tool to remove the color of the screen, so that the overall appearance of the screen as a black-and-white effect, easy to next color processing.

2. Create the overall tone of the picture. Apply the "curve" tool to increase the contrast of the screen, and the red and blue channels are adjusted to slightly increase some red, remove some blue, so that the screen slightly partial color.

This adjustment, in general, mainly divided into 9 steps, the following based on layer parsing, nine steps to the overall interpretation of the total (please refer to the map below):

1. Original background layer, no adjustment.

2. Make the lens correction, change the perspective relation, revise the character distortion.

3. Lengthen the characters ' legs, so that the characters are slightly higher, and visually play a role in reducing the seats.

4. Picture tailoring, character Center, prepare for next operation.

5. liquefaction treatment, adjust the people's arms and shoulders, so that the characters more slim.

6. Remove unnecessary parts of the screen, such as white yarn, such as the person's armpit, so that the screen cleaner.

7. For the screen to increase the dynamic, the position of the skirt positioning fuzzy treatment.

8. Treat the photo as black and white effect, easy to unify the color.

9. Use the Curve tool to add color to the picture, so that the overall color of the picture.
