If you’re both a photography lover and a Mac user (there’s a lot of you out there, right?), computer expert Lloyd Chambers has an uber-helpful section on his Mac Performance Guide website for photographers who want to learn how to optimize a Mac for Photoshop and other photo editing programs.

Photoshop is a pretty resource intensive program that can slow down to a crawl when you’re working with large and/or many files. Aside from beefing up your hardware specs to provide the program with more memory or disk space, there’s also a number of Photoshop and operating system preferences you can adjust to make sure the program runs as smoothly and quickly as possible. The Photoshop performance team recently published a helpful guide with 19 adjustments you can make, which range from optimizing cache level to turning off thumbnail display.

This video, created by PhotoErrant, shows a Canon 7D shooting at 8 frames per second on high-speed continuous mode. This definitely isn’t something you should try yourself, since it whacks hundreds of shutter actuations off the lifespan of your camera and exposes the sensor to dust. Luckily for us, there’s people willing to do these experiments and upload them to YouTube.
