Tasks. 9

Laboratory work No. 1. Acquaintance with the graphic editor Adobe Photoshop.

The purpose of the work: To study the tools of the graphic editor AdobePhotoshop, and how to configure it in various modes. Familiarize yourself with floating panels and their purpose. Learn how to create and save different types of files in Adobe Photoshop.

Theoretical part

Currently, there are a large number of computer programs designed to create and process graphic information. AdobePhotoshop is the biggest whale in the sea graphic editors. It allows you to process photos, create book and magazine illustrations at a high professional level.

Photoshop mainly works with raster graphics, although it can handle vector images as well. Most often, such images are obtained using a digital camera, by scanning an image, or by “capturing” a video frame.

A raster image is a matrix of colored dots. Raster images require a large amount of memory to store. Such images are difficult to scale and edit.

The main parameters of a bitmap image are:

image size (in inches, centimeters, points, peaks, etc.);

resolution (number of pixels per unit size);

color depth (number of bits per pixel).

Tasks

In the left corner is the toolbar - these are the tools of your work. With these buttons you will select, move, transform and color your image. When you press any button, it becomes active - this element is selected. Not all buttons fit on the panel - some are hidden. Select the Rectangle Selection button. Click and hold your mouse on the small triangle in the lower right corner of the button - you will see what is actually hiding there 4 various ways selection.

3. On the right side of the screen are PALETTE. There are only 13 palettes and they are combined into several groups. If the palette is not on the screen, it can be called up via the WINDOW menu. Each palette has a menu, which is called by the right arrow.

So that the palettes do not interfere with viewing the image, they can be removed with the SHIFT + TAB keys. The same keys will return the palettes to their place.

Pay attention to the palette Color . It allows you to set the foreground color and background color. The corresponding color can be selected by moving the sliders R (for red) G (for green), B (for blue). You can enter a numeric value for each color, or simply click the eyedropper to sample the color.

Create a new file with the menu command FILE - NEW. In the dialog box, specify the parameters with which the document will be created:

Appeared new document 300x300 pixels at 72 pixels per inch with a background layer filled with white. Working with a document without seeing its actual size is quite difficult, so you should turn on the ruler guides (VIEW - GUIDES or CTRL + R).

Select the tool " Brush". Using the palette Color”, select the color of your brush (for example, light green). Use your mouse to write the word Photoshop at the top of the window.

Apparently it didn't work out too well.

D To align objects along lines, set image boundaries, check vertical and horizontal lines, it is convenient to use guides(solid blue lines). Click on any ruler and drag the pointer down or to the right. Guides can be moved using the " moving". In order not to accidentally move the guides during operation, they can be fixed (VIEW - FIX THE GUIDES). You can temporarily hide them in VIEW - SHOW - GUIDES, or delete them (VIEW - CLEAR GUIDES).

Set some guides and try to write the text again (select the brush color - dark blue).

It is also convenient to work with the included grid: VIEW - SHOW - GRID.

For change scale images serves panel Navigator . On this panel, you can view the entire image in a thumbnail view. The part visible in the window is marked with a red frame. You can change the scale directly by entering a percentage value, smoothly moving the slider, or clicking on the buttons Decrease And Increase .

Magnify the image by 2 times (200%).

Choose a tool Brush and try to draw. (To clear the entire image, use EDIT - FILL - USE - WHITE or SELECT - ALL - Delete.)

Pay attention to the properties panel at the top of the screen.

Here you can choose another tool,form brushes, mode,turbidity,flow and enable features atomizer.

Try working with different brush shapes: hard round, soft round, spatter(splash), chalk(chalk), star(star), grass(grass), leaves(leaves), fuzz ball(wet ball) dry brush(dry brush). Choose from a variety of brush sizes and colors.

Customize in more detail form brushes can be done using the BRUSHES palette.

brush property Turbidity (more correctly - transparency). Makes the injected color transparent (the color becomes lighter, showing through the previous image). While you have not released the mouse button (one stroke) - painting goes in an even layer.

brush property Flow . Acts like haze. But at the same time, its own trace is painted over (that is, the dynamics of the movement of the brush is taken into account).

Button Enable sprayer capabilities works if the current is less than 100% (preferably 10-20%). Holding down the mouse button in one place makes the image brighter (as if you were holding down a spray gun button).

Fill the picture field with images of different colors and brightness. Now try changing the mode:

Select a 19 px hard round brush, set the color to a medium brightness (for example, dark blue), and successively change the modes, canceling each last action(CTRL+Z):

ModeNormal(Normal)

In this mode, the original color is completely replaced by the imported one.

ModeMultiply(Multiplication)

In this mode, the colors of the source and the input are "multiplied", so the resulting color is always darker than the source.

If black is introduced, the resulting color also becomes black. White color does not affect the original.

ModeScreen(Screen)

In this mode, the colors of the source and the input are "split", so the resulting color is always lighter than the source. If white is introduced, the resulting color becomes white. Black color does not affect the original.

Modeoverlay(Overlap)

This mode darkens dark colors and brightens light ones. As a result of this superposition of pixels, the contrast of the image is increased.

ModeSoftlight(Soft light)

This mode enhances or weakens the color depending on the applied color (the result is similar to ambient light lighting)

If the input color (think of it as a light source) is lighter than 50% gray, the original color is whitened (lightened) identical to the tool Dodge (Lighter).

If the input color is darker than 50% gray, the original color is enhanced (darkened) in the same way as when the tool is working Burn (Darker).

Using pure white or pure black lightens or darkens the original color, but does not produce pure white and black, respectively.

ModeHardlight(hard light)

This mode enhances (darkens) the color, as in the Multiply(multiply), or weakening(lightening) colors as in mode Screen(Screen), depending on the applied color (the result is similar to lighting with a harsh light).

If the input color (consider it also a light source) is lighter than 50% gray, the original color is whitened identically to the mode Screen(Screen). If the input color is darker than 50% gray, the original color is enhanced in the same way as Multiply(Multiplication)

Using pure white or pure black is identical to normal mode.

The mode is very convenient for creating shadow areas.

ModeDarkens(darker colors)

In this mode, the original colors are replaced, namely, only those that are lighter than the entered one, and the points that are darker than the introduced one remain unchanged.

Modelighten(lightening color)

In this mode, the original colors are replaced, namely, only those that are darker than the entered one, and the points that are lighter than the introduced one remain unchanged.

ModeDifference(Difference)

In this mode, the resulting color is equal to the difference in brightness between the source and added colors. As a result of this overlay of pixels, the effect of a negative image is created.

ModeHue(hue)

In this mode, the resulting color gets the color tone(hue) of the injected color, but retains the values saturation(Saturation) and brightness(Luminosity) of the original color. Try painting the image with a shade of black.

ModeSaturation(Saturation)

In this mode, the resulting color receives the saturation of the input, but retains shade(hue) and brightness(Luminosity) original. Grayscale images are not affected in any way.

Modecolor(Color)

In this mode, the resulting color is obtained with brightness(Lummosily) original but with shade(hue) and saturation(Saturation) of the input. This allows you to keep the gray scale. It is widely used for color toning of a monochrome image.

ModeLuminosity(glow)

Or rather, brightness. In this mode, the resulting color is obtained with shade(hue) and saturation(Saturation) of the original color, but with brightness introduced. In the gray scale, the result coincides with the input tone. This mode is the opposite of the mode color(Color)

ModeDissolve(Dissolution)

To see the effect of this mode, you need an additional condition. Set in the box Opacity(Turbidity) value 50%.

In this mode, the original color is replaced by the imported one with a random distribution and transparency. The result is especially noticeable with large instrument sizes. Paintbrush(Brush) or airbrush(Airbrush) and partial turbidity.

And now, using the knowledge gained, try to color the black and white image of a butterfly in the grass (file Butterfly Peacock Eye.jpg ).

Introduction to Adobe Photoshop

Theoretical part

Currently, Adobe Photoshop is one of the most popular image editing software in the world. It is widely used by both amateurs and professionals.

Adobe Photoshop users - photographers, retouchers, advertising artists, illustrators, designers, architects, etc.

The vast majority of illustrations are prepared for printing and publication with the help of this program, since Adobe Photoshop allows you to perform a very large number of image processing operations: for example, improving the clarity of a photo so that they do not look blurry and incorrect. Retouching tools allow you to remove scratches, dirt and damage from the image.

Editor features:

1. Create greeting cards

2. Drawing posters

3. Drawing collages

4. Drawing covers, booklets, and posters

5. Creation of graphic elements for Web pages

6. Drawing a business card

7. Create stylish logos

8. Photo retouching

9. Restoration of damaged photos

10.Change the appearance of the photo

11. Creation of animated pictures

The working window of the program Adobe Photoshop:

In addition, Photoshop is often used to create collages, in which fragments of different images are merged together for unusual effects.

When working with Photoshop, you should distinguish between image resolution and monitor resolution.

Image resolution - is the number of pixels per unit length of the image. Typically, an image is measured in pixels per inch (1 inch = 2.54cm) (ppi).

For example, if the image resolution is 72 ppi, then 1 square inch of the image contains 5184 pixels (72 horizontally, 72 vertically, 72*72=5184). The same square inch of a 144 ppi image contains 20.736 pixels (144*144=20.736).

Resolution is defined when an image is digitized with a scanner, digital camera, or created in graphics program.

The higher the resolution of the image, the higher its quality, since in this case more color shades can be transmitted.

The file size of a bitmap image depends on the number of pixels per inch. The larger the image size, the larger its file size.

Monitor resolution - the number of video pixels per unit length (in one inch). The resolution of the monitor depends on the set graphic grid size. Most often, a resolution of 72 video pixels per inch (dpi) corresponds to a graphic grid of 800 * 600, and a resolution of 96 dpi corresponds to a graphic grid of 1024 * 768.

When working with raster images, it is important to understand that monitor resolution has nothing to do with image resolution.

Practical part

Lab #1

Target:

Basic concepts

Selected area- a fragment of the image within which the editing tools operate. The selected area is bounded by a blinking dotted line.

masked area- an image located outside the selection. This area is not editable and therefore protected from accidental changes.

ToolMarquee (Region) designed to select rectangular and elliptical areas.

Group Tools Lasso (Lasso) is used to select areas of arbitrary shape.

ToolMagic wand (Magic wand)- used to highlight pixels that are close in color.

Image cropping- cropping the image (removing unnecessary fields, fragments of the environment, etc.).

Task number 1: Create a vignette to decorate your photo.

Launch Adobe Photoshop using the icon

Open a photo - a portrait Portrait .jpg using the "Photoshop Pictures" folder located in the folder My documents are my drawings. The program window should look like this:

Select a tool from the toolbar Ellipti Withal Marquee (Oval area).

Feather the photo by selecting in Menu expiration date– Selection - Feather. Feathering will create a smooth transition between the pixels in the selection and the pixels surrounding the selection.

Enter in the field " Feather selection» value 10.

6. Run the command Selection - Inversion. The selected and masked areas will swap places.

7.Press the key Delete , to delete the selected area.

8. To remove the selection, run the command Selection - deselect.

9. Before you - a photograph with a feathered vignette.

10. Save the image to your folder, naming it "Portrait".

Task number 2: Apply your own photo to your work and create a vignette.

Lab #2

Target: Learn how to edit low-quality images and arrange them.

Task number 1: Create a photo with a sepia tone.

1.Launch the Adobe Photoshop program using the icon

2. Open the photo you took in the previous lesson.

3. Run the command Image - Grayscale mode.

The color photo will turn into a black and white image. Now let's replace the shades of gray with two colors - black and brown (this is sepia). In general, a black and white image can be illuminated with three or four colors.

4. Run the command Image - Mode - Duplex. In the window that appears, select "Two-color".

5.Select the second type of paint Pantone 1545 C by clicking on the white box:

In the window that appears, find the color type Pantone 1545 C :

Click the button OK. On the screen, you will see an image with a warm sepia tone, embellished with a feathered vignette. Thus, you can make photos "antique".

Save the photo.

Task number 2: Apply your own photo to the work. Age her.

Lab #3

Target: Learn how to edit low-quality images and arrange them.

2.Open the Fruit file.

3.Using the tool Lasso, V

Select only the red apple

along the contour.

4. Make 2 copies from the selected apple. To do this, with the apple selected, press and hold the key , move the mouse cursor over the selected apple and “drag” to the left a few centimeters. You should end up like this:

5. Copy the yellow rose 3 times. After the changes, the drawing should look like this:

Task number 2. Open the yellow file. Perform copy and paste operations so that the drawing looks like this:

Lab #4

Target: learn how to make a collage

Basic concepts:

Collage- a combination of several fragments of different images in one.

Layer- an analogue of a sheet of transparent film on which a drawing is applied. If you fold such sheets in a stack, you get an image of several drawings. It can be argued that the image on the layer is an analogue of the object vector graphics.

Background layerbackground- the farthest.

Basic operations on layers- deleting, moving, rotating, scaling, changing the order of layers, transferring image fragments from one layer to another, merging layers.

PanelLayers (Layers) used to work with layers. It displays information about the layers of the active document. In addition, this panel allows you to perform various operations on layers.

Task 1: Create a collage.

1.Launch Adobe Photoshop.

2.Open the file " Seasons ».

3.Open the " Layers" ( in the main menu, select the "Window" option, check the box layers). Note that the Layers panel contains only one background layer.

4. Open the file " bird ». There is only one layer in this document, on which the image of a bird is located. In this case, the transparent areas are presented in the form of a checkered pattern.

Transparent areas

Press the left mouse button, and without releasing it, move the cursor to the Seasons document window. Release the mouse button. A new layer has appeared in the Seasons document, which shows a bird from the Bird document:

7. Open the leaf file with a leaf image.

8. Move the sheet to the Seasons document:

9.Open the file " Flower". Using the tool Lasso,

highlight the flower along the outline. Execute the command Editing - copy.

10. Activate the window " Seasons"(Click on it with the left mouse button). Execute the command Editing - paste. The image that should turn out is presented below:

Task 2: Create your own collage using different pictures.

Lab #5

Target: Learn to edit images

Basic concepts:

Main color(foreground color) - the color that is used for drawing, filling selected areas, and also as the initial color of the gradient.

Background color(background color) - the color that appears when pixels are removed from the image.

By default, the foreground color is black and the background color is white. The colors of the front and back plans are indicated in the color fields on the toolbar.

ToolPencil (Pencil) allows you to create lines with hard borders.

ToolBrush (Brush) used to draw lines with a smooth, blurry outline.

ToolEraser (Eraser) erases unnecessary parts of the image by painting them with the background color.

ToolPaint bucket (Fill) is used to fill parts of an image with a uniform color or pattern.

ToolGradient (Gradient) is designed to create fills with smooth transitions between different colors.

Toolsmudge (Finger) used to offset and blend the colors of adjacent pixels.

Properties panelOptions (Options) contains information about the parameters of the selected tool.

Pixel blend mode- a way of interaction between the pixels of the source image and the drawing tool.

Task 1: Colorize a black and white photo

2.Open the file " dog". You need to choose the right colors and paint over the dog and the bowl with the bone.

3.Select a dog with a bowl and clouds.

Target: Learn how to tone correct

Basic concepts

tone range- brightness range of image pixels. The darkest shade corresponds to the brightness of O, and the lightest - 255.

bar chart- a graph of the distribution of pixel brightness. The horizontal axis is the brightness values, and the vertical axis is the number of pixels for each brightness level.

Shadows- the darkest part of the image with low brightness values.

Light colors (lights)- the lightest part of the image with high brightness values.

midtones located between shadows and light tones.

black dot is the darkest pixel in the image.

white dot- the lightest pixel in the image.

Gamma- - the contrast of the midtones of the image. Gamma range - from 0,1 before 9,99.

Basic concepts

Color circle- a diagram that shows the relationship between the basic colors of the RGB and CMY models.

blue

The relationship of color models RGB and CMY is as follows:

1. Colors lying opposite each other on the color wheel (the line connecting from passes through the center of the circle) are mutually related: a decrease in the content of one color leads to an increase in the content of another color and vice versa.

2. Each color on the color wheel is defined as the sum of adjacent colors to it. The content of any color can be changed by influencing the colors adjacent to it.

Color correction feature changing one color causes the other colors in the image to change.

Task number 2. Eliminate small defects from the photo.

Open file « FRUIT (if it is closed).

Make a copy of the drawing.

If you pay attention to the lower left corner, you will see a defect that needs to be removed.

Using the tool Rectangular area select a fragment of the image with a defect.

Execute the command Filter - Noise-Dust and scratches. A dialog box will open Dust and scratches. Field Radius defines the size of the area that is used to average the colors of adjacent pixels. The smaller the field value Border, the less the colors of neighboring pixels differ from each other, and vice versa. Combining different values in the fields Radius and Border, you can quickly remove dirt and scratches from photos.

Set field value Border equal to 12, and the value of the field Radius - 16.

Click OK. The defect has been fixed.

8. Compare the result with the original and close the copy.

Task number 3. Eliminate a defect from a photo with the Stamp tool.

Set the stamp size. Choose a brush (stamp tip) with soft edges of a small size, for example 30.
