How to Reimage a Macintosh Computer (6 Steps)

Attach an external hard drive to your Macintosh that has at least as much storage capacity as the space used on the drive you are imaging. You can skip this step if you already have a second drive with enough free space.
Launch the Disk Utility application from the Applications/Utilities folder.
Select the drive you wish to image by name in the list on the left-hand side of the Disk Utility window. This list will also include drives by their serial number. You should usually ignore these in favor of the named drives; however, select the drive by serial number if you want to create a single image of a drive with two or more partitions.
Choose 'File' > 'New' > 'New Disk Image from...', which will display the name of the drive you have selected.
Select the external drive in the Save dialog. If you wish, select a compression format and encryption method. Compression will create a much smaller disk image which still contains all the information on your original drive. Encryption will require a password before the disk image can be opened; if you lose this password, you will not be able to access the contents of the disk image.
Click 'Save' to create the disk image. Disk imaging can take a long time, especially if you are creating a compressed or encrypted disk image. You can continue to use your Macintosh during this time, but it will run more slowly due to the disk access required by the imaging.

How to Use Special Effects on a Mac iSight Camera

Open iChat and start the video camera. You can do this by clicking on the camera icon next to your name or selecting PREVIEW VIDEO from the VIDEO drop down menu. Once you have started the camera, select SHOW EFFECTS from the VIDEO menu.
From the special effects toolbox simply select the effect you want to see displayed in the video preview window. Notice the ORIGINAL view is always present in the center of the selections so you can easily flip back to the normal camera view.
Scroll through the effects pages using the scroll keys. The original is always in the center. There are six pages of effects, so take your time and experiment with all of the different ones. Keep in mind that flipping through the effects can be irritating to the people you are chatting with; you have to be in a playful mood.
There are also video effects. The roller coaster and fish tank are my favorites. Notice that your image will be in the center of the video effect and the video will run behind your image. Your chat members may see you on a roller coaster or in front of Yosemite Falls. Kids seem to love the video effects, although I am not sure how the grandparents may feel about them.
You can also add your own backgrounds from image files. Simply select an image file and you will see your camera image in front of the image background. This actually has a practical use for trainers and business. For example, you could put your company logo tiled behind you, which would give the look and feel of being at a press conference. The special effects are a fun way to add a little pizazz to a business conference or to just get a little wacky when chatting with family and friends.
