Camera Calibration for Raw Files

Camera Calibration and Profiles Video

Vision is the most important part of photography. Your eye is what makes the difference between a great photograph and a mediocre one.

But when realizing your vision and making it come to life in the final image, getting the right color is vital.

Recently I posted two videos about using curves in Photoshop, Lightroom, and Camera Raw. But there’s a more fundamental step that I haven’t talked about, something you might want to do with Raw files before adding curves, correcting white balance, or doing anything else: choosing a profile.

What is a Camera Profile?

A camera profile is a translator: it’s translates the colors that a camera captures into the colors they should be. In other words, if a certain camera tends to turn reds into orange, the profile will correct for that and convert those reds back to their proper hue. Of course there’s no such thing as “correct” color—it’s all subjective. So profiles can come in different flavors: more saturated, less saturated, more contrasty, etc. Choosing the right flavor for your image is the first step toward making your visualization come to life.

I’ve posted a new video on YouTube that delves into this seemingly esoteric yet actually quite simple subject. In it I show you how to choose different profiles in Lightroom, and explore whether creating a custom profile might be worthwhile. I evaluate some profiles I made with the X-Rite ColorChecker Passport, a $99 package for making custom camera profiles in any lighting situation. Yes, full disclosure, they actually gave this to me for free—I must be hitting the big time!

Also, there’s one more reason for exploring different profile options: reducing noise, banding, and posterization. I show an example where the profile choice made a dramatic difference in noise and banding.

Camera Calibration Tab in Adobe Camera RawI didn’t have time to demonstrate it in the video, but the same profile choices are also available in Adobe Camera Raw—just look under the Camera Calibration tab, third from the right, as shown here.

So here’s a link to the video:

Using Curves in Lightroom and Camera Raw


Curves in Lightroom and Camera Raw

As promised, I’ve posted another tutorial on YouTube about Curves in Lightroom and Adobe Camera Raw. In this video I examine the default settings in these applications, and why you should avoid using them—at least sometimes. These defaults actually apply three curves to your image before you even start processing it. Watch the video to see what’s really going on “under the hood” with the settings in Lightroom and Camera Raw.

Again I had to break this into two parts; here are the links:

I hope you enjoy these—comments are always welcome! To see everything clearly you need to view in high resolution—click on where it says 240p or 360p in the lower-right corner and choose 480p. Also, if  you click on the little double-sided arrow you’ll see the video larger.

The Power of Curves

The Power of Curves

I did something I’ve wanted to do for a long time: post a video tutorial on YouTube. It’s called The Power of Curves, and it’s about, well, curves in Photoshop. This is one of those things that’s just easier to show than explain, so it’s a perfect subject for video.

I think Curves are the single most powerful tool in the digital darkroom; if you learn to master Curves, you’re well on your way to mastering image-processing. Curves tend to intimidate some people, as they seem foreign if you haven’t used them before. But Curves are really quite simple, and I hope this video helps clarify how to use this amazing tool. I had to break this into two parts; here are the links:

The Power of Curves Part 1

The Power of Curves Part 2

Originally I had wanted to talk about the new Point Curve feature in Lightroom 3, but then realized that I needed to explain some basics about Curves first, and that Photoshop was a better tool for that. But I’ll post another video in about two weeks about using Curves in Lightroom and Adobe Camera Raw, and about dealing with their strange default settings.
