HDR Processing Techniques – A New Video Tutorial   25 comments

It’s finally here!

I’ve long wanted to create a video tutorial as a way of passing along ideas that others have contributed along the path of learning HDR processing. It took the urging of one Mark “Konaflyer” Patton to have me get down to business on the project. (Hence, the title of the image, “Pier Pressure.”) Mark had emailed, wanting to know how I achieved a certain “glossy” look to some of my HDR images. As it turns out, creating the video — and working on Mark’s brackets — was a lot more fun than I expected! Best of all, Mark has graciously agreed to let me post his image and the video for all to see in the interests of passing along knowledge to others. Thanks, Mark! Please be sure to visit Mark’s great Flickr photostream.

Perhaps… it was a bit too much fun. The resulting video turned out to be an hour long as I took Mark’s brackets from the original RAW files to the final product you see here. Although Mark has viewed this in its entirety, I had to break it into five different parts in order to satisfy the 15-minute restriction on YouTube.  That’s okay, I figure; In between segments you can get a cup of joe, slap yourself awake, or otherwise lift your spirits as we get down to some of the fine points of post-processing. I promise that next time I create a video, I’ll make it 15 minutes, or less.

I’ve included the embedded YouTube videos here. Later, when this blog post gets buried in the archives, you can access the videos via my Tutorials page. Or, if you’d like to subscribe to my YouTube channel, you can receive updates whenever new videos are posted.

You can view the videos directly from this blog page, or view them on YouTube. Either way, please remember to view them in 720p mode if your system is capable of that.

This is my first go at creating a video and posting it. So, if you see anything amiss, please let me know right away.  If you find anything useful or helpful in all of this, I’d love to hear about that as well. Comments and feedback are always welcomed here.

Cheers, and happy viewing.

Big Back Yard

With sunrises like this, it’s hard to leave the place. This was taken one morning at Cobscook Bay State Park in northern Maine, not far from Lubec.

Our tent is just a few feet behind this point of view, making morning shooting very convenient. We often joke about our new campsites having a much bigger back yard than we have at home, and we find no greater pleasure than to just sit and watch nature do its thing, or to capture it in the process.

On a side note, I often think twice about posting in portrait orientation due to the limits of today’s monitors, but in this case, I think it suits the subject well, although I may next try a vertical panorama.

Once again, this image was composited in Photoshop by layering outputs from seven brackets in Photomatix Pro 4, HDR Expose/32-Float, and HDR Efex Pro. Each had something interesting and unique to offer to the final image, and none really created what I wanted in and of itself. Beyond that layering and masking, there was very little done in the way of color or saturation. In fact, I knocked back the saturation a bit using Topaz Adjust ‘Neutralizer’. In the end, this image represents what I saw that morning, but sometimes you have to coax it out of the brackets.

Oceanana Pier made it through the night.

Hurricane Earl passed by Atlantic Beach, NC, on September 2nd, 2010.  This was taken shortly after the owners of Oceanana Pier closed off access to the pier, for good reason. The crowd of spectators that had been gathered at the end of the pier to watch the waves and surfers quickly reconvened on the beach. When you’re standing so close to these powerful waves, it seems that you just can’t stop watching, and you’re sure that next wave will be even bigger and more badass than the last.

Oceanana Pier is one of the last remaining fishing piers on Emerald Isle.  Whereas there were once a good number of piers all along Emerald Isle, relentless hurricanes and even more relentless real estate development have caused the removal of all but three — Oceanana, the Sheraton Pier, and the Bogue Inlet Pier. In addition to being great places to fish, the piers also create nice wave breaks for surfers. Now that so many piers have been removed, it’s causing large crowds of surfers as they bunch up to take advantage of the few good remaining surf spots.
