Computers are excellent machines for creating and editing graphics. Graphics are picture files.
By the end of this unit you will learn:
Visual Literacy exercise.
Find out and explain the meanings of each of the key words, in the context of graphics editing, in a new word document.
Firstly open Adobe Photoshop CS6
Looking at the Photoshop screen in front of you, answer the following questions:
Repeat this with fireworks, Then write a comparason of the features of photoshop and Fireworks. Use the following headers to help you; , 'What is the same?', 'What is different?', and 'What do you think the different programs are used for?'
File and Bytes
Use the two images above, download then and use Photoshop's 'save as' function to convert each into the different file types. Create the table below using MS Word/Excel and compare.
File Type | Description | File Size | Appropriate uses for format |
---|---|---|---|
BMP | |||
JPEG | |||
PNG | |||
PSD | |||
BMP |
Compare the difference between the file types and the filesize in bytes.

Final Picture:
In this activity you will learn how to clear-cut PSD images.
What is clear-cutting an image?
Cutting an image simply means removing the original background so that the focus of the canvas is just one object. The benefit of using a clean-cut image is being able to place the image on any background you choose. This is a great technique to learn when using images on websites or posters. In addition, you can also use clear-cut images on signs, banners, and icons without dealing with distracting backgrounds.
What is PSD?
PSD is simply Photoshop's special image (or photo) format. You have heard of JPEG (which is the most common format) or GIF formats. Most photographs on the internet are in JPEG format. PSD formatted images usually work better in Photoshop, so this is the format we will be using in this activity.
Why use PSD?
When we are editing images we need to store a lot more information than when we present the same image in the final production. We use the PSD format as it contains information about layers, and much more information about the image so that we lose less information when we edit the picture.
To start with, you will need to select an image to work with. Make sure the image will be easy to work with.
Upload your work into Moodle Activity Task 3 Upload slot
Try the following methods:
Original Image
It’s important to ensure that you have applied all edits, such as contrast, levels, colour and saturation before you start the teeth whitening edits.
The next step is to duplicate the layer. It can be helpful to name it something like ‘teeth whitening’ or similar for reference. Once this is done, you can select the area you want to edit – in this case, the teeth.
Before you start, make sure you have ‘paths’ selected (found in the top left hand corner).
You can then simply click to set the path points around the teeth, making sure that you click and hold, then move up or down to adjust curves as necessary. Remember, it doesn’t have to be perfect, as long as you have all the teeth outlined.(Complete Task 4: Learn 5 uses of clipping path to get the idea about some ways to apply the paths technique.)
Once you have your outline, right click and ‘make selection’. It can be useful to feather (the 1 pixel setting will be enough) just to smooth out the edges. Then, simply copy and paste the selection, where you can start adjusting the hues and tone as preferred.
Once back in standard mode with your selection active, you can adjust the hues and tone of the teeth by setting the hue/saturation to yellow, value around 80, in the main menu (Image – Adjustments – Hue/Saturation). Use the dodge tool, and set range to midtones and exposure to around 15%. You can then use a large brush that covers your selection to make teeth look whiter.
