Eyedropper tool: You can choose the color in the image as the painting color of the brush tool.

Measuring tool: measure the distance and angle of projection on the perspective plane.

Zoom Tool/Grip Tool: Zoom window and move screen.

Copy an image in perspective.

1) executes the Filter-Vanishing Point command to open the Vanishing Point dialog box.

2) Use the Create Plane tool to add nodes to the image and define the perspective plane. (if you make a mistake, you can gradually return to the original through Alt+Ctrl+Z, and Ctrl+Z returns once; If you undo all operations, please hold down the Alt key and click the Reset button to restore all operations. )

3) Use the marquee tool to select an object, place the cursor in the selection, hold down the Alt key and drag the mouse to copy the image, and then click OK.

Why is the perspective plane red?

Blue bounding box: It is an effective perspective plane.

Red and yellow bounding box: invalid.

Attention? If you create a new layer before using the vanishing point, the modification result will appear on the layer without damaging the original image. If you want to keep the perspective plane information in the image, you can use PSD, TIFF and JPRG to store files.

10-6 Create a panorama with Photomerge.

When shooting a landscape, if the wide-angle lens can't capture the whole picture, you might as well take a few photos from different angles and splicing them into a panorama with photoshop.

{Drag multiple photos used to synthesize holograms into a document, and use the Edit-Auto-Align Layers dialog box, which will automatically align layers according to similar contents (such as corners) in different layers. You can specify a layer as the reference layer, or you can let photoshop automatically select the reference layer, and other layers will be aligned with the reference layer, so that the matching content can be superimposed by itself.

1) Open three pictures.

2) Execute the "File _ Auto-Photo Exposure Command"-"Layout-Auto"-"Add Open File" button-add three photos opened in the window to the list, and then check the "Mixed Image" option to let photoshop automatically modify the exposure of photos to make them naturally connected.

3) Click the OK button, and Ps will automatically flatten the photos and add layer mask to make the photos seamlessly connected.

4) Use the rectangular box selection tool to select the photo content, execute @ Image-Crop commandism, and cut off the blank area or redundant image content. Don't use cropping tools, automatic edge alignment will make alignment difficult.

Attention? Several photos used for the panorama of the play should overlap to some extent.

10-7 Edit HDR photos

HDR image is a high dynamic range image composed of multiple photos of the same scene or the same person with different exposures, which is mainly used in movies, special effects, 3D and so on. HDR is a reduction of high dynamic range.

10-8 lens defect correction filter:

10-9 lens special effects production filter.

Lens blur, scene blur, aperture blur and tilt offset filters are powerful filters to simulate lens special effects. For example, "lens blur"-making depth of field effect; "Aperture blur"-can sharpen a single focus;

Making depth of field effect with lens blur filter

Lens blur will add blur to the image. And 1 uses the depth value of Aloha channel or layer mask to map the pixel position, so that some objects in the image are in focus and another purple area is blurred, resulting in the depth of field effect.

1) Open the material and use the quick selection tool to select the object that needs to be the foreground.

2) Select the "Adjust Edge" dialog box in the tool options bar to feather the selection, then click the "Save Selection" button in the channel panel to get the channel of Alpha 1, and press ctrl+D to cancel the selection.

3) Execute the "Filter-Blur-Lens Blur" command-select the "Alpha 1" channel from the "Source" list. Define fuzzy range with channel selection; Aperture-Shape-Octagon 8, and then adjust Brightness and Threshold to generate a beautiful octagonal spot?

4) 1 Repair the bright spot in the upper right corner with the imitation stamp tool. The effect has appeared.

Lens blur filter options:

Faster: It can improve the preview speed.

More accurate: it will increase the preview time.

Depth Map: Source—Creates a depth map using the Alpha channel and layer mask. If the image has an Alpha channel and this item is selected, the black area in the Alpha channel is considered as the front of the photo, and the white area is considered as the distant position. The "Paste Focus Horizontal" option is used to set the depth of the focused pixel.

Aperture: used to set the fuzzy display mode.

Specular Highlights: used to set the range of specular highlights.

Noise: Add noise. Distribution: the distribution of variegated colors.

Monochrome: Add variegated colors.

Scene blur can be applied to different areas of the movie scene by one or more pushpins.

1) Open the material and execute the "Filter-Blur-Scene Blur" command, and a push pin will appear in the picture.

2) Place the cursor on the pushpin, click and move it to the stamen, and then set the fuzzy parameter to 0 in the fuzzy tool panel on the right side of the window.

3) Click the stamen and add a pushpin. "Fuzzy" parameter 0

4) Cancel "Preview" and add a few pushpins.

5) Adjust parameters: click the push pin to select adjust and delete. Check the preview again.
