With iPhoto you can assign keywords to your photos, and later do a search by keyword to find the one you want. Keywords are category labels you add to your photos to help you quickly and easily find all the photos in a specific category. For example, you might assign the keyword "Family" to all of the photos that have family members as subjects, or assign the keyword "Nature" to any photo you take while hiking.
When you want to find photos by date, just click the Calendar button to display the Calendar pane, and then select the year, month, week, or date of the photos that youre looking for.
To remove a keyword from a photo, first select the photo, open the Get info window, and choose the Keywords tab. Un-check the keywords you want to remove from the photo, and close the window.
As you use keywords more often, you will find some words work well and others dont get used very often. To rename a keyword, select it in the Keywords Preference window, click the Rename button, and then type a new keyword. To delete a keyword, select it in the Keywords Preference window and click the Remove (-) button.
To display keywords below your photos in the photo viewing area, choose Keywords from the View menu.
iPhoto comes set up with a few common keywords for you to use. If you would like to add or change these keywords go to iPhoto Preferences, and then click Keywords. From this window you can add keywords by clicking the Add (+) button and typing the keyword you want.
Sometimes your photos might need to have more than one keyword associated with them. iPhoto allows you to easily add more than one keyword to your photos. Open the Photo Info window, and select the Keywords tab. From this window you can select that multiple keywords are associated with your photos.
From the Keywords pane, you can click as many keywords as you want. By default, only photos that match all the keywords you select will be displayed. For example, if you have select "Kids" and "Birthday", only photos with both the "Kids" and "Birthday" keywords will be displayed. Hold the Shift key as you select keywords from the Keywords pane, and notice that the keywords are now highlighted in purple. Photos that have either "Kids" or "Birthday" keywords will be displayed.
