​Lesson 3 - Objectives 3-5 (Tuesday)

B03-03 Skill: Panning, zooming, and rotating the image view in Photoshop

Objective:
  • Understand how to pan, zoom and rotate your views in Photoshop
​Learn:
When using Photoshop to work on images, it is critical that you can zoom in (or out) on an image to make adjustments. The Zoom tool (Z) is used for that. With the zoom tool selected...

  • Click on any area of your image to zoom in. Each click zooms further in.
  • Hold the option key down (ALT on PC) and click to zoom out. Each click will zoom you further out.
  • Click and hold the mouse down to zoom in.
  • Hold the option key down and click and hold the mouse to zoom out.​
Pressing and holding the spacebar at any time will switch you to the hand tool, where you can pan the image by dragging with the hand tool. Work through the tutorial "Panning, Zooming, and Rotating Views in Photoshop" to learn how to do this. Be sure to try it out yourself.

B03-04 Skill: Understanding file formats and screen resolution

Objective:
  • Understand that Photoshop can save images in many different formats, and which ones we will use in this course.
  • ​Learn:
Photoshop supports many file formats, both for opening (or importing) files and for exporting (or saving files).  For a complete listing, visit the Adobe Help page - Supported File Formats.  For our class, we'll be mostly JPG, PSD, Camera Raw, or PNG files.
  • Camera Raw file format saves images directly from the camera sensor data, so you get "raw" unprocessed picture data.  These are large files that contain 4096 levels of brightness for each color.
  • PNG, or Portable Network Graphics, is a raster graphics file format that supports lossless data compression.  PNG was created as an improved, non-patented replacement for the Graphics Interchange Format (GIF), and is the most used lossless image compression format on the internet.
  • JPG (or JPEG), from the Joint Photographic Experts Group, is a highly compressed image file format, used when files need to be very small - such as for websites or email attachments.  JPG images only have 256 levels of brightness for each color.
  • PSD (or Photoshop) files are Photoshop's native file format that saves all the information and adjustments you've created.  It saves the layers, the layer adjustments, the masks, and everything else Photoshop needs to let you re-edit the image.

No required exercise file. Be sure to practice this on your own!
As we work together through this course, image resolution will be very important to the success you have in Photoshop, and also reducing file size for posting your portfolio exhibits to your online portfolio. A couple of key points to keep in mind:
  1. When you create or work with your Photoshop files, make sure the shortest side is at least 1000 - 2000 pixels.
  2. When you save images to upload to your online portfolio, you'll want to make sure that the longest side in no more than 1000 pixels at 72 DPI.
