HDR with Photomatix Pro

with 3 comments

Alright, I finally did it. I broke down and gave HDR a try (click image above for large version). Creating a HDR or high dynamic range image involves blending multiple exposures together in order to display detail in the final image that would otherwise be lost in a single exposure. Our eyes are capable of looking at a scene with bright highlights and dark shadows and still see an immense amount of detail. Cameras simply don’t have that kind of ability, which is why blending exposures is useful when a scene contains very bright and very dark elements at the same time.

I set my D300s to automatically bracket a series of photos for me at 1 stop increments, and here’s what I got out of the camera:

Notice that if the sky looks good, the beach looks too dark. Conversely, if the sand looks detailed, the sky is blown out. There’s simply too much range for the camera to pick up detail in all areas of the frame. Yes, I suppose I could have used a split neutral density filter to even things out, but the purpose of this shoot was to experiment with HDR.

Exposure blending used to be extremely difficult, requiring the use of multiple layers, masks, and a whole lot of brush strokes to manually bring out detail in the HDR image. Nowadays, it’s dead simple. Photoshop has a “merge to HDR” feature built-in, but it’s not quite as good as standalone software like Photomatix Pro, which I used to merge this HDR image. All I had to do was drag the four bracketed images above straight from Lightroom 3 Beta 2 into Photomatix Pro, specify a few parameters, and POOF! It spit out an HDR image. Of course, what you see at the top of this post is not what you get right after the merge in Photomatix. I still had to tone map the HDR, then export it as a standard image file back into Lightroom for post-processing before it looked satisfactory.

I’m pretty excited about how easy the process was. My goal was to try to convey the scene the way my own eyes saw it, and I have to say that the final result looks very close to what I experienced that evening. Overall, I’m glad that I decided to give HDR a try, and I look forward using this photographic tool again.

Autumn’s First Storm

Today, northern California was pounded by a powerful tropical storm that came from Japan, wreaking havoc on the morning commute in the city, knocking out power in several areas, and causing some flooding problems. As I write this the rain has stopped. But over the course of the day, winds of up to 55 mph and heavy rainfall battered the city.

I took the shot above at Baker Beach last night. The clouds were dark and dramatic, and diffused the dusky light from the sky, allowing me to take some long exposures shortly after sunset. It was a long walk down the beach and back with all my gear, but the trek was well worth it.

I realized after shooting here last night that I haven’t actually been to Baker Beach in a long time. In fact, the last time I was here was nearly six years ago. Not too far from the spot where I took this shot is where I proposed to my wife of five years, and that is the last memory I have of this beach.

After getting some great images out on the Beach, I headed to the Palace of Fine Arts on my way home for a few more photos. I’m still tired from all of it!
