Lynda - Black and White with Lightroom and Photoshop (Updated Jun 19, 2015)

Shoot in color, but think in black and white. In this course, Adobe Photoshop principal 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. Finally, take your photos (and video!) to the next level using the Silver Efex plugin and mobile apps like Photoshop Mix and Express. Bryan closes with a video that pulls all the lessons together in a single end-to-end workflow.
