If you've been hankering to learn Lightroom, then today is your lucky chance, photogs! Creative Live has a free Lightroom Mastery workshop that starts today and runs through the 19th. If you can't catch it the first time around, don't worry—they loop the classes for three days straight, so you always have a chance to check in on the class and learn some new skills.
Here's the course description via Creative Live:
"Use Lightroom, but feel like you're not getting the most out of it? Ben Willmore's Lightroom Mastery is for you! Learn how the adjustment sliders affect your images, how best to use the histogram, and how to fix your problem images. Learn to organize your images so you can easily find them later, and see a complete workflow from ingestion to printing or output. Then push your retouching beyond the basics to accomplish complex retouching jobs, and explore your options for adjusting localized areas within your images. Once your images are organized and adjusted, extend Lightroom with third-party software, create books and slideshows, and learn to print and post images on the web. Join Ben and master Lightroom!"
