Week 1

Hello. My name is Devina and welcome to my blog. This is where I post a summary of every class I have in the Multimedia Authoring course of LUCT.

Chapter 1

This week, we covered Chapter 1: A Quick Tour of Adobe Photoshop. Our lecturer introduced us to Adobe Photoshop, an image-editing software used to edit graphics. Here are what the logos look like, from the oldest to the newest:

In Photoshop, we can save our files with various graphic file formats, including:

• .gif (graphics interchange format)
• .jpg / .jpeg ("Joint Photographics Experts Group", the group that created this standard)
• .raw = raw image format
• .png (portable network graphics)

There are several file formats that Photoshop offers which allows the user to preserve layers. These formats include (in order of file size):

• .pdf (portable document format)
• .psd (Photoshop document)
• .psb (Photoshop big)
• .tiff (tagged image file format)

Pixels are tiny squares that make up an image. Resolution is the number of pixels that make up an image or fill up a screen, meaning width x height.

There are three types of resolutions:

• monitor resolution, the resolution of your screen - measured in ppi (pixels per inch)
• image resolution, the resolution of an image - measured in ppi
• printer resolution, the resolution of what's being printed - measured in dpi (dots per inch)

Higher resolution images print out smaller.

We were also taught how to use the basic tools in Photoshop.
This is how the default interface looks like on Photoshop CC:

On the left is the toolbox bar, which has the tools needed to adjust and edit the photo.

Several things you could do are select, move, crop, clone, brush, insert text, erase and more. A magnifying tool is also there to let you zoom, but it is much easier to zoom by pressing ctrl and +/-. There are also several other windows you could use to allow easier navigation, control the history of tasks and more.

Okay that's all for this week.
