Now that I've covered how I get my images into Lightroom and how I organize them, now I'll cover one of the ways I get my images out - Publish Services.
I use Publish Services for pushing images to different social media like 500px, Flickr, Facebook. I started using the built-in Flickr plugin but have switched to the plugin created by Jeffrey Friedl, mainly for the ability to find and link to existing images up on my Flickr account.
I haven't published to my hard drive because I haven't come across a need to keep images on my hard drive. I typically export images to my hard drive using export presets, which I'll cover next time.
