Deke's Techniques 231: Fixing a Noisy High-ISO Photo with Adobe Camera Raw

Reducing Noise in a High ISO Photo

I have a vested interest-slash-concern in this week's free Deke's Techniques episode, in which he takes a photograph of yours truly---a hand-held shot at high ISO under government-supplied lighting---and attempts to redeem it with Adobe Camera Raw. My interest is that it's a flattering shot from a great day at Carlsbad Caverns; my concern is that the high noise is not only making my skin look blotchy, but horror-of-horrors, it's causing my jacket to look purple

But with some thoughtfully applied ACR adjustments, Deke effects this delightful transformation:

Working in ACR, Deke first uses the Temperature and Tint sliders, as well as controls in the HSL and Lens Correction tabs to (thank goodness) return my jacket to its proper neutral black. But the real work in this photo transformation happens in the Detail tab: Read more »

Photoshop CS5 One-on-One: Advanced Goes Live

Some of you have been asking when my Photoshop CS5 One-on-One: Advanced series is coming out. And I was all prepared to tell you this Friday. But lynda.com, being the incredible juggernaut of a video publisher that they are, began releasing it today. Chapters 13 thru 18 are up this very second. That's more than 100 movies, so it should keep you occupied for now. (If not, I totally suck.) The remaining Chapters 19 thru 24 will be up in 10 days.

Here's a live-action frame from the series. My director told me that, in retrospect, my spendy Elie Tahari shirt "looked a little disco." Let me assure you that this is one of the best shirts I've ever owned. It's a matte forest green with some excellent under-collar and inner-sleeve highlights. In the video, I don't look disco, I look positively wet. Meaning that I glisten. Like someone is misting me. Which is not necessarily what you want in a training video. But it's what you get.

That said, who gives a tinker's gumph what I look like? Read more »
