Some of the keyboard shortcuts have changed since Lightroom 4. Here are the common ones that have impacted my workflow:
Toggling through screen modes (normal, fullscreen, fullscreen w/o menus) used to simply be the F key under Lightroom 4. In Lightroom 5 the F key now shows a fullscreen preview of the selected image. Shift-F is the new shortcut. If you want to jump straight to fullscreen w/o menus, Ctrl-Shift-F (Cmd-Shift-F on Mac) is the new shortcut.
Jump straight to the new Radial Filter Tool: Shift-M. This works within the Develop module, or right from the Library.
Traditional Spot Removal Tool: Lightroom 5 now adds the ability to draw non-circular spot removal areas, an awesome feature to be sure. Simply click and drag to start painting your non-circular removal area. In Lightroom 4, clicking and dragging would define the spot (the click,) then define where the fill should be sourced (the drag.) If you want this same behavior in Lightroom 5, hold down the Ctrl key (Cmd on Mac) and click-drag to set the spot and source in one fluid motion.
This morning I ran into a battery issue with my Canon 5d mark III, and in the interest of being thorough, I wanted to do a full system flush on the camera. You know the flush I mean – where you pull the battery, card, and even the clock battery, then let the camera sit for 30 minutes to completely “flush” the system. Think of it as a thorough system reset.
Anyhow, I quickly discovered that the clock battery is not stored in the same location as it is on my older 5d mark II. A quick Google search turned up plenty of references to performing the process, but nothing that indicated just where the clock battery was located or how to remove it. Since I was on my own, I decided to go exploring and post images of the process.
You’ll need a very small Philips-head screwdriver; something you might use for repairing glasses. There’s only a single screw to remove, but be very careful not to lose it.
