But why would I have to keep holding the Option key after the initial Option-Spacebar to get the full screen previews? Shouldn't all the images I originally selected be full screen? It used to work this way in Mountain Lion. Maybe a bug in Mavericks?
I guess we need to define "full screen" and "full size" so we're sure we're talking about the same thing.
For me, full size means that the image is shown in its true pixel dimensions, and full screen means that QuickLook takes over the entire screen, displaying full size images on a black background. Further, images that are opened in full screen QuickLook can be zoomed in upon to fill up the screen either vertically or horizontally, depending on the image's format, in relation to my screen's dimensions.
When I QuickLook images (one or more) in full screen by pressing option-space bar, the image (or, the first image in a group) appears full size on a black background that fills my screen.
When I press the right arrow key, the next image in my selection opens full size on top of the same black background.
When one of the images I have selected is open on the black background in full-screen QuickLook and I press and hold the option key, that image is zoomed to fill up the screen, and when I let go of the option key, the image zooms back out to its full size.
Alternatively, and if this option is enabled in System Preferences > Accessibility > Zoom, I can hold the control key down and use scrolling gestures to zoom in and out of images open in full screen QuickLook.
That is, as far as I know, QuickLook's expected behavior.
