How PS uses the eyedropper tool

The Eyedropper tool is an information tool, and the information tool includes color sampler tools and measurement tools. The three tools display information about the point at which the cursor is located in different ways, and the shortcut key for this tool is the letter I.

Eyedropper tool

You can select the color in the image, and the information Panel displays the information about the point where the cursor has slipped.

The eyedropper tool's taskbar, shown in Figure 3, uses the sample size option to set the Eyedropper tool's color range (as shown), including the sampling point, the 3x3 average, and the 5x5 average.

Color Sampler Tool

You can define up to four sampling points in the image, and color information will be saved in the information Panel. We can use the mouse to drag the sampling point to change the location of the sampling point, if you want to delete the sampling point, just use the mouse to drag it out of the canvas.

Using the Metrics tool, you can measure information between two points or two lines. The information is displayed in the Information Panel. Use the method: Select the Metrics tool Click OK start on the image, drag out a line, click to determine a line segment, and then press ALT to create a second measurement line.

Here we must have some understanding of the straw tool! Hope for everyone later PS process help!

Here the author explains the use of the Photoshop CS6 eyedropper tool in detail through concrete examples.

1. Quick and accurate sampling of colors

Using the Eyedropper tool, you can draw a certain color from the image,

Or, the color is sampled with the average color around the pickup point, which changes the foreground or background color.

(1) Execute "file" → "open" command, the material "apparel advertising. tif" File open.

(2) Select the Eyedropper tool in the Toolbox, click anywhere in the view,

You can draw the color you click on, and the color you draw by default replaces the foreground color in the toolbox.

(3) To confirm that the Eyedropper tool is selected, click the bottom triangle button of the sample size option in the options bar,

You can eject the Drop-down menu, where you can choose what range of colors to draw.

(3) Select the "51x51 average" option and then click in the same position as Step 1 to draw the color,

The color it absorbs is the average color value of the 51x51 of the clicked point like Sovane,

At this point the foreground color has changed and is no longer yellow.

(3) We can also replace the drawing color background color, in the "Color" palette click on the edge of the background color block,

You can then continue to use the Eyedropper tool to click in the view to replace the background color with the drawn colors.

2. Apply the target color exactly to the drawing object

You can also use the eyedropper tool to quickly pick colors and draw graphics with drawing tools such as brush tools, pencil tools.

(1) First execute "file" → "open" command, the material "character line draft. tif" File open.

Tip: To enable designers to put their energies all on the drawing, Photoshop provides users with shortcuts to switch between the brushes and the eyedropper tools. When the brush is selected, pressing the ALT key on the keyboard switches to the Eyedropper tool, and when you draw the color, the release of the ALT key is automatically converted back to the Brush tool, where you can continue drawing in the artwork.

(2) Select the Brush tool in the toolbox and set its options bar, and then the key,

You can change the mouse to the Eyedropper tool, click on the color bar on the left, and draw the color.

(3) Release the key, the mouse will be changed back to the "brush" tool,

We can then use the foreground color on the online manuscript image to draw the image.

(4) Use the same method, absorb the color and then draw the image, complete the drawing of the character image.

3. Use target color to correct image color

In addition, there is a very important role is to draw the color of different positions, and then in the "information" Panel to see the color value, using high-quality color values, to correct the color of the image.

(1) Execute "file" → "open" command, the material "characters 1.tif" and "People 2.tif" file open.

(2) to determine the "character 2.tif" file is active, select the "eyedropper" tool in the Toolbox,

and set its options bar.

(3) Set the sampling point in the high light area of the character face, and the "Information" palette will be automatically popped up.

Displays the RGB color value at the sampling point in the information palette.

Tip: The color value obtained from the high light area of the image is to match the image in the People 1 document.

(4) and then activate the "character 1.tif" file, with the press key,

Click to set the sampling point again in the facial light area of character 1.

The following replaces the RGB color values that you draw in the People 2 document with the color values that you draw in the People 1 document.

(5) perform "image" → "Adjust" → "level" command, open the Levels dialog box,

In the dialog box, select the "Red", "green", "blue" channels,

and adjust the RGB value by dragging the middle-tone slider.

Tip: When you drag the slider, observe the changes in the RGB values in the information palette.

(6) After the completion of the click "OK" button to close the dialog box, observe the "information" palette,

The color that you draw in character 2 replaces the color value in character 1.

(7) Refer to the above method, with press the key,

Set up the sampling points in the dark regions of characters 1 and 2, in turn.

(8) Press the key, open the "Level" dialog box, according to the above method set the "Red", "green", "blue" channel option parameters,

Replaces the extracted RGB color values in character 1 with the RGB color values that are absorbed in character 2.

Matches the dark regions of two character images.

(9) Learn how to edit the sampling point to confirm that the Eyedropper tool is the selected state.

Press the key when the mouse changes, click and drag to move the sampling point.

(10) Press the key, put the mouse on the sampling point,

When the mouse changes, click to remove the sampling point.

(11) Finally, the remaining sampling points are deleted, so as to complete the production of this example.
