5. The _____________ tool helps in moving objects in a given layer around the Adobe Photoshop canvas. 

Ans: Move.

6. The _______________ tool helps in selecting a part of the canvas in a specific shape. 

Ans: Marquee.

7. The ______________ is a free-form selection tool that lets you drag around the canvas.

Ans: Lasso.

8. The colour ________________ palette is a set of pre defined colours. 

Ans: Swatches.

B. Subjective question:

1. Describe the functions of any five drawing and painting tools of Adobe Photoshop.

Ans: (i) Paintbrush: Paintbrush is a tool that resembles a paintbrush… The paintbrush, however, can be set to different kinds of brushes. One can paint using standard paintbrush and airbrush styles, or even with leaves and other shapes.

(ii) Clone stamp: The clone stamp tool allows the user to duplicate a part of an image. Like healing brush, clone stamp lets the user sample a part of a photograph and use it to paint over another part.

(iii) History brush: History brush lets one paint back in time… The History Brush allows you to restore parts of an image to an earlier history state by painting over them.

(iv)  Eraser tool: The eraser tool changes pixels to either the background colour, or to transparent. It erases pixels as you drag it across the image.

(v) Paint bucket tool: The paint bucket tool lets one fill in a specific area with the current foreground colour.

A. Match the Columns:

Ans:

B. Subjective Questions:

1. Explain the following modes of blending.  

(a) Dissolve. 

Ans: Edits or paints each pixel; the resultant colour is a random replacement with base or blend colour depending on opacity. Visible only when layer opacity is below 100%.

(b) Darken. 

Ans: Pixels lighter than the blend colour are replaced, and those darker than the blend colour do not change.

(c) Colour Burn. 

Ans: Looks at colour information in each channel and darkens the base to reflect the blend by increasing contrast; blending with white produces no change.

(d) Linear Burn. 

Ans: Looks at colour information in each channel and darkens the base to reflect the blend by decreasing brightness; blending with white produces no change.

(e) Screen. 

Ans: Look at each channel’s colour information and multiplies the inverse of the blend and base colours; result is always lighter—black makes no change, white produces white. 

2. Describe the use and application of blending modes.

Ans: (i) Blending mode, as specified in the options bar, controls how pixels in the image are affected by a painting or editing tool. The majority of blend modes have keyboard shortcuts.

    • The base colour is the original colour in the image.

    • The blend colour is the colour being applied with the painting or editing tool.

    • The result colour is the new colour formed from the blend.

(ii) Modes set the method for blending the colour one paints with the underlying existing pixels. The available modes change with the currently selected tool. Paint modes are similar to layer blending modes.

(iii) Import two different photographs and resize them to overlap with each other in two different layers. Now, select the topmost layer and change the blending mode of this layer to Colour Burn. Now, observe the difference in the blending of these two different images in the same file.

(iv) Import two different photographs and resize them to overlap with each other in two different layers.  Now, select the topmost layer and change the Blending Mode of this layer to Overlay Mode. Now, observe the difference in the blending of these two images in the same file.

(d) Four printed colours.

Ans: (c) 256 grey shades. 

B. Subjective Questions:

1. Differentiate between grayscale mode and indexed colour mode.

Ans: 

2. Write short notes on the following: 

(a) RGB colour mode.

Ans: Photoshop RGB colour mode uses the RGB (Red, Green and Blue) model, assigning an intensity value to each pixel. In an 8 bits per channel image, the intensity value ranges from 0 (black) to 255 (white) for each of the RGB components. For example, a bright red colour has an R value of 246, G of 20 and B of 50. When the values of all three components are equal, the result is a shade of neutral grey. When the values of all components are 255, the result is white. When the values are 0, the result is black. 

RGB images use three colours or channels to reproduce colours on screen. In 8 bits per channel image, the three channels translate to 24 (8 bits × 3 channels) bits of colour information per pixel. With 24 bits images, the three channels can reproduce up to 16.7 million colours per pixel.

(b) CMYK colour mode.

Ans: In the CMYK mode, each pixel is assigned a percentage value for each of the process inks. The lightest (highlight) colours are assigned small percentages of process ink colours, while darker (shadow) colours have higher percentages. For example, a bright red might contain 2 per cent cyan, 93 per cent magenta, 90 per cent yellow, and 0 per cent black. In CMYK images, white colour is generated when all the four components have values of 0 per cent. 

One needs to use the CMYK mode when preparing an image to be printed using process colours. Converting an RGB image into CMYK creates colour separation.

(c) Grayscale mode.

Ans: Grayscale mode uses different shades of grey in an image. In an 8 bits image, there can be up to 256 shades of grey. Every pixel of a grayscale image has a brightness value ranging from 0 (black) to 255 (white). In a 16 and 32 bits image, the number of shades is much greater than that in an 8 bits image.”

“Grayscale values can also be measured as percentages of black ink coverage (0 per cent is equal to white, 100 per cent is equal to black).

(d) Bitmap mode.

Ans: A Bitmap is an image where each pixel is either black or white (no shades in between). Bitmap images can be compressed making the file size very small, despite having a lot of pixels. It is useful for printing or archiving paper documents. The bitmap colour mode has a bit depth of 1, hence also called bitmapped 1-bit images.

(e) Indexed colour mode.

Ans: Indexed colour mode produces 8 bits image files with up to 256 colours. When converting to indexed colour, Photoshop builds a colour lookup table (CLUT), which stores and indexes the colours in the image. If a colour in the original image does not appear in the table, the programme chooses the closest one or uses dithering to simulate the colour using available colours. Although its palette of colours is limited, indexed colour can reduce the file size and yet maintain the visual quality needed for multimedia presentations, web pages, etc. For extensive editing, one needs to convert the existing image temporarily into RGB mode. 

Indexed colour files can be saved in Photoshop, BMP, DICOM (Digital Imaging and Communications in Medicine), GIF, Photoshop EPS, Large Document.

A. Fill in the Blanks:

1. The _______________ command in Adobe Photoshop enables you to adjust the colours in your image, based on their hue. 

Ans: Saturation.

2. The colour ______________ command changes the overall mixture of colours. 

Ans: Balance.

3. When adjusting an RGB image, the upper-right area of the graph represents the highlights and the lower-left area represents the ___________________.

Ans: Shadows.

B. Subjective Questions:

1. Describe the functions of the following combination of keys: 

(a) Ctrl + m.

Ans: Curves: Lets you adjust points across an image’s tonal range; moving points changes highlights, midtones, and shadows to refine contrast and tone. 

(b) Ctrl + u.

Ans: Hue/Saturation: Adjusts colours based on hue, saturation, and lightness; you can target Master or specific colour ranges and fine-tune with sliders.

(c) Ctrl + l.

Ans: Levels: Corrects tonal range and colour balance by adjusting intensity levels of shadows, midtones, and highlights using the histogram and sliders. 

(d) Ctrl + b.

Ans: Colour Balance: Changes the overall mixture of colours in an image for generalised colour correction (RGB-based). 

(e) Ctrl + z.

Ans: Undo: The standard Undo toggles between undoing and redoing the latest action; the History palette allows going much further back (about 50 actions by default).

A. Fill in the Blanks:

1. A painted representation of a landscape or distant location that allows a filmmaker to create the illusion of an environment that is not present at the filming location is known as ________________ painting. 

Ans: Matte. 

2. __________ paintings made through the Adobe Photoshop usually resemble a real painting made with real brushes and paint and they look more realistic than a vector painting or illustration.

Ans: Raster.

B. Subjective Questions:

1. What is ‘matte painting’?

Ans: Matte painting is a creative technique that filmmakers use to create backgrounds for scenes that cannot or do not exist in real life. It is an old technique in the visual effects industry. It is a painted representation of a large landscape that allows filmmakers to create the illusion of an environment that does not exist. It combines several techniques including 3D, photo manipulation, painting as well as retouching techniques in order to achieve quality result. Mattes are used to combine foreground image with the background image. The output depends on the skill level of the artists and technicians involved in matte painting. 

2. Describe the steps of matte painting in Adobe Photoshop.

Ans: Before starting the matte painting scene, make a rough sketch of the world that you would like to create. You can refer to some images that could help you in your matte painting for colour correction and for the Depth of Field (DoF). You also need to decide the size of your painting. The range of the painting’s dimensions would depend on its intended use. 

Step 1:

Open a new document by going to File > New and create a blank canvas of 5,700 × 3,900 pixels. 

Click and drag the photograph into the new document. Place the photo in the centre of the canvas, and then move it to the bottom right. 

Search the photo of Machu Picchu using Google Image search and download the same.

Step 2 

Use the Photoshop Eraser tool to remove the photograph’s sky area and then create a new layer named ‘Outlines’ above the photograph. We will now start extending the original plate. 

Select a soft standard brush of about 30 pixels and start drawing in the general outline of the new scenery that the user is going to add.

Step 3 

Now that we have the general outlines of our new image, we can start painting in a bit more detail. 

Always begin with the element that is the furthest (usually, sky). 

Select the ‘Background’ layer and create a new layer named ‘Sky’. While still in brush mode, hold down Alt key to turn the cursor into a colour eyedropper and select the grey/ blue colour of the background mountains in the photograph. 

Now, use this colour to block in the sky.

Step 4 

Add some storm clouds to the sky and establish the light source. Use a variety of different sized soft brushes and light  pen pressure to slowly build up the layers of stormy clouds. Also, add the sunbeam to give a more realistic look.

Step 5 

Ensure the ‘Sky’ layer is still selected and create a new layer called ‘Right mountain’. 

Use the same technique that you used for creating the sky. This can be done by picking the colour of the right-hand mountain on the photograph and then blocking in that colour on your extension. 

Add a few more details to the mountain by picking various shades from the original photograph by applying it to your new layer. 

The sky and landscape extensions are all your imagination, but you can also use reference photographs.

Step 6

Select ‘Layer 1’ (the layer that is the original photograph), and now create a new layer named ‘Right Foreground Mountain’ (Figure 3.59). 

Repeat Step 6, but add little more detail. Use the original photograph as the colour palette in order to keep a uniform and balanced colour scheme all along the picture.

Step 7 

Now, create a new layer and name it ‘Left Foreground Mountain’. 

Paint rough details as in the previous step.

Once done, select ‘Layer 1’ again and create a new layer named ‘Middle Ground’.

Step 8 

We will now add the final creations over the original plate, which includes the waterfall and another small peak towards the background of the ruins. 

Once done, delete the ‘Outlines’ layer. The rough layout must look similar to the screen capture. This sketch will give a strong feel of what exactly the final composition will look like, displaying the elements, such as colour, lighting and perspective view. 

In the next step, we will start to render our matte in more detail and try to give the painted area more of a photo realistic look.

Step 9 

We will start with the sky again. Select the ‘Sky’ layer and with a variety of different sized brushes, build up the layers of cloud. One can always find a large-sized photograph and paste it in, retouching it a bit with some brushwork. 

Make use of adjustment layers and colour overlays placed over your sky layer, to view changes without affecting your working layer.

Step 10 

Now, we have painted in some distant mountains beneath the sky to give the painting more depth. They are just flat colour silhouettes with some highlights added to the edges. 

Once the sky is done, go to Filter > Noise > Add Noise and add a bit of Gaussian Noise to help it match the ‘film’ grain of the original plate.

A. Fill in the blanks: 

1. Rule of Thirds is not any rule, but it is a guideline intended to help you when you are uncertain as to the placement of elements in a _________ or when you are framing the picture. 

Ans: Scene.

2. In Rule of Thirds, the whole image is divided into _____________ equal segments by two vertical and two horizontal lines. 

Ans: Nine.

3. The two types of balance in photography are _____________balance and informal balance. 

Ans: Formal.

4. Informal balance, also called as ____________________ balance is the one in which one or more dissimilar elements are balancing on each side of a given point. 

Ans: Asymmetrical.

5. Symmetry refers to a sense of harmonious and beautiful proportion and _____________. 

Ans: Balance.

6. Cropping is the removal of ________________ outer areas from a photograph or an image. 

Ans: Unwanted.

7. Photomontage is the technique that involves the act of combining pieces of photographs and using different types of ______________ materials. 

Ans: Graphic. 

B. Subjective Questions:

1. Write short notes on the following: 

(a) Rule of thirds. 

Ans: Rule of Thirds is not any rule, but a guideline intended to help when the user is uncertain regarding the placement of elements in a scene, or when the user is framing the picture. As we have studied about the Rule of Thirds in Chapter 2, the whole image is divided into nine equal segments by two vertical and two horizontal lines. It implies that one must position the most important elements in a photo or scene along these lines, or at points where they intersect. By doing so, it will add balance to the photo.

(b) Symmetry and patterns. 

Ans: Symmetry refers to a sense of harmonious and beautiful proportion and balance. We are surrounded by different types of symmetries and patterns — both natural and man-made. These can be used to define and draw the focus of the viewer to the subject. They can be used as eye-catching compositions; particularly in situations where they are not expected. 

(c) Leading lines. 

Ans: When we look at a photo, our eyes are naturally drawn along lines. Lines in the composition can affect the way we see an image, pulling us into the picture or towards the subject in the scene. There are many different types of lines namely straight, diagonal, curvy, zigzag, radial, etc., and each can be used to enhance the composition of photo.
