iPhoto 11 sometimes displays photos at a small size, with a black band on all four sides of the photo. This happens when I press the back and forward arrow keys to go through my event:
Notice the black band on all four sides of the photo.
I looked at a few photos for which this happens, and they seem to be around 1800 x 1200. This is less than the physical resolution of my display, which is 2880 x 1800. This does not happen for photos whose dimensions are larger than the screen resolution. Having said that, I'm not sure that this diagnosis is correct.
Can I tell it to always fit the photos to the screen (like Lightroom's Fit mode) as I go through the photos in my event or album using the arrow keys? That is, never leave a black band on all four sides of the photo. Thanks.
