Among the many new features in Adobe Photoshop CC, there are several enhancements to the Camera Raw controls which now allow you to make far more nondestructive tweaks to your images than ever before.
How to get the most out of Camera Raw as well as other new Photoshop CC features are explained in detail in Photoshop CC One-on-One: Advanced – a Lynda.com course taught by renown Photoshop expert Deke McClelland.
Totaling nearly twelve hours of high-level instructional videos, the advanced course covers everything from creating custom shortcuts to advanced blend mode to advanced blur gallery techniques, and much more – including this eight-minute chapter on managing exposures via Camera Raw.
