Photohop PM Bryan O’Neil Hughes has posted a new 42-minute course that’s free until June 21:

Shoot in color, but think in black and white. In this course, Adobe Photoshop Senior Product Manager Bryan O’Neil Hughes shares his favorite techniques for transforming color photographs into black and white, a technique that provides more creative options than using your camera’s black-and-white mode. Learn how to prepare and fine-tune your photographs in Lightroom, and then move them into Photoshop to take advantage of its nondestructive adjustment layers. The course also introduces techniques for using Photoshop to adjust the color of video clips.
