I often use full screen mode with no visible filmstrip to show photos to people, clicking through them one at a time with right-arrow. It's quick because I don't have to wait for previews to render (necessary to use the built-in slide show feature of Aperture), but there are some disadvantages to doing things this way. First, I have to show all the images in the album or project: I can't make a selection. Second, at the end of the photos there sits the last one on the screen: no blank screen.

To fix both of these problems, I use command-click. Here's how:

• Make sure the display is in Primary Only mode (option R). This makes the viewer show only one of the selected images at once.

• Select images using shift-clicking and command-clicking until the selection is as desired

• Go into full screen mode with F

• The first selected image will be displayed -- command-click it

• The next image is displayed. Keep command-clicking until all images have been displayed. On command-clicking the last one, a blank screen will appear.

[Added from the comments:]

Add an image of your logo (or URL or whatever) to the album or project. It doesn't matter where it is in the browser, as long as you click on it *last* to add it. Then click on the first image you want to show and hit F. Now the last image to be shown will be the logo.

Using the method of display above, images are shown in the order added to the selection, so you can not only choose what to show, but the order as well and very easily.
