PS Lesson 03
You were beautiful until your Photoshop trial expired.
You were beautiful until your Photoshop trial expired.
This test will focus on the theory of last week. You've created two assignments around some important Photoshop techniques and gained knowledge about the design industry.
With 22 questions on these topics, you will test yourself. Do you master the knowledge already, or do you need to study harder? Anyways; Good Luck!
The test will be shared by the SOFT2 teacher during the first class through a Microsoft Teams assignment. Immediately after the test, we will review the answers together as a class.
Working with Selection tools

Select and Mask
Select an Object
A selection isolates one or more parts of the image. By selecting specific areas, you can edit and apply effects and filters to portions of your image while leaving the un-selected areas untouched.
Photoshop provides separate sets of tools to make selections of raster and vector data. For example, to select pixels, you can use the marquee tools or the lasso tools. You can use commands in the Select menu to select all pixels, to deselect, or to re-select.
To select vector data, you can use the pen or shape tools, which produce precise outlines called paths. You can convert paths to selections or convert selections to paths.
Selections can be copied, moved, and pasted, or saved and stored in an Alpha Channel.
Alpha Channels store selections as gray scale images called masks. A mask is like the inverse of a selection: it covers the un-selected part of the image and protects it from any editing or manipulations you apply. You can convert a stored mask back into a selection by loading the Alpha Channel into an image.
While selecting one of the Selection Tools you will be able to Select and Mask from the Options bar. This will allow you to adjust your selection and preview its accuracy against a solid white or black background. Click on the View mode to see the option. Click on the F Key to cycle through it. Adjust the transparency of the stages including Onion Skin to see a better view of your selection.
Other stages in the same dialog box include - Edge Detection to select hair and areas that are not straight, Adjusting Edge, and output options. On the left side we have editing tools.
Photoshop works with Selections to isolate an area and create layers. No matter which selection tool you are using remember the goal is: TO GET THE BEST SELECTION EVER - therefore you can combine selections, to accomplish the best selection. You can start with one selection tool and use others to help you do the best selection.
The question is: Which Selection shall I use?
The one you are most comfortable with that will make the best Selection. Look at your image and make the right decision. If you see a shape that looks like a rectangle...Use the rectangle tool. The more practice the better Selections. Good Selections will make great-looking layers.
When you are working on your image you actually save your selection and load it whenever you need to use it.
Save your selection
Did you know that you could also save your selection? Making a great selection takes some time. It's not really motivating if you need to start over again to recreate the same selection. An important selection can be saved from the Select menu by selecting Save Selection.
Simply give your selection a name.
Load your selection again from the same menu with Load Selection.
Your selection will also be saved in your Channels panel.
Channels: Are gray scale images that store different types of information:
Color information channels: Are created automatically when you open a new image. The image’s color mode determines the number of color channels created. For example, an RGB image has a channel for each color (red, green, and blue) plus a composite channel used for editing the image.
Alpha channels: Stores selections as gray scale images. You can add alpha channels to create and store masks, which let you manipulate or protect parts of an image.
Spot color channels: Specify additional plates for printing with spot color inks.
An image can have up to 56 channels. All new channels have the same dimensions and number of pixels as the original image. The file size required for a channel depends on the pixel information in the channel. Certain file formats, including TIFF and Photoshop formats, compress channel information and can save space. The size of an un-compressed file, including alpha channels and layers, appears as the right-most value in the status bar at the bottom of the window when you choose Document Sizes from the pop‑up menu.
You can use the Channels panel to view any combination of channels in the document window. For example, you can view an Alpha Channel and the composite channel together to see how changes made in the alpha channel relate to the entire image.
Individual channels are displayed in gray scale. In RGB, CMYK, or Lab images, you can view the
Individual channels in color. (In Lab images, only the a and B channels appear in color.) If more than one channel is active, the channels always appear in color.
Download the Still Life.PSD from the Google Drive folder
Follow the steps in the video and try to understand what you are doing. Know the theory behind it.
Create Spot Channels for all the objects in the picture using several selection techniques.
Red: 7621C (C 20%, M 100, Y 95%, 15%)
Orange: 158 C (C 0%, M 49%, Y 85%, K 9%)
Green: 362 C (C 49%, M 0%, Y 70%, K 38%)
Place your image on your Spark page and describe briefly what you have done.
