There are several ways to create a slideshow in iPhoto:
- You can select an album from the Source list and click on the Slideshow button on the toolbar, or
- You can select individual pictures in an album and click on the Slideshow button to create a slideshow with only the selected pictures.
Once you create a slideshow you can set a number of options on the Slideshow toolbar. You can add transitions by selecting them from the Transitions pull-down menu.
You can also use the “Ken Burns” effect used in iMovie (which allows you pan and zoom on still images).
You can click on the Settings button to open up a window with even more options.
You can change the default duration for each slide, or set the default transition used throughout your slideshow. You can also choose to show the image’s title, any ratings you have assigned to it, or slideshow controls. You can create a slideshow that loops when it reaches the end by placing a checkmark next to Repeat slideshow.
To use the Ken Burn effect, first make sure the box next to it is checked in the toolbar. You will see a button below it that can be set to either Start or End.
To begin creating your Ken Burns effect, set this button to Start and use the slider at the bottom of the window to change the zoom level you want to start with when the slide begins playing. You can also place your pointer anywhere in the image to move it around in the window and change the starting focal point. Once you’ve set your Start options, switch the button to End and use the slider to change the zoom level you want to end up with when the slide finishes playing. Again, you can place your pointer on the image and the pointer will change to a hand icon to let you know you can move the image.
One popular option is to include music that plays while the slideshow is displayed on the screen. To add background music, first click on the Music button (which looks like the iTunes icon).
iPhoto brings up a dialog box that shows all of your music from iTunes.
By clicking on the Play Music checkbox and selecting a song from the list, you can add background music to your slideshow. If your music is too short for the slideshow you’ve created, you can tell iTunes to repeat it by opening the Settings window and making sure Repeat music during slideshow is selected. You also have the option of having the slideshow fit your music. iPhoto will adjust the duration of each slide and the speed of the transitions so that the slideshow has the same duration as the music you’ve selected.
To preview your slideshow, click on one of the two play buttons in the toolbar. The button on the left allows you to preview your slideshow from beginning to end, while the button on the right allows you to preview the currently selected slide.
You can export your slideshow into a movie you can post on any website. To export a slideshow as a movie, make sure you select the slideshow in the Source List, then select File, Export.
You can set some options for your exported movie such as its size and save location.
