The last few pages have helped you get ready; now it's time to customize each slide. Remember that each of these actions is optional!
To customize slides:
Select the first slide in the scrolling list above the display pane.
Choose an effect to apply to the photo from the Effect pop-up menu. See "Editing Slide Photos" on the next page for more information.
To override the default transition, choose a different transition from the Transition pop-up menu (Figure 5.9).
Figure 5.9. Use the controls in slideshow mode to customize the way each photo displays in the slideshow.
To override the default slide duration, click the Adjust button, and click the up or down triangle buttons to increase or decrease the slide duration. You can also override the default transition type, direction, and speed here (Figure 5.10).
Figure 5.10. Use the Adjust This Slide window's controls to override default settings for slide duration and transition type, direction, and speed.
If you're using the Ken Burns Effect, use the Start/End switch along with the size slider to control the effect. See "Configuring the Ken Burns Effect," later in this chapter.
To see how your changes look, click the Preview button to preview the current and next slides in the display pane.
Select the next photo by pressing (the right arrow key), clicking the right arrow button, or clicking the photo in the scrolling list. Then repeat steps 27 until you've customized each slide as desired.
You can access all the slideshow tools by -clicking anywhere in the display pane and choosing the desired command from the contextual menu.
If you find yourself unable to change the amount of time a slide will stay on screen, the reason is likely that you selected Fit Slideshow to Music in the Settings dialog. Since iPhoto has to calculate the length of time to display each photo when that checkbox is selected, it prevents you from changing the slide durations.
