Favorite FlickR Fotos for Friday, 3/23/2012

This week I thought I would spotlight some images created using optical filters. "The Basic Book of Photography" by Tom and Michele Grimm has a full chapter on filters. You can find a good discussion on photographic filters (including internet references) on Wikipedia. Given that I have immediately pointed you to other material, you may have guessed that this blog update is not a treatise on filters, their use, etc.

Filters are just one of the many tools that photographers use when creating images. There are hardware tools like optical filters, tripods and monopods, ball heads, panning heads, nodal rails and robotic panning heads, gimbal heads and bush hawk shoulder mounts. There are software tools including raw image editors, filters and processors and post-raw image editors, filters and processors. Manufacturers of these tools include Acratech, Adobe, B&W, Bushhawk, Cokin, Gigapan.org, HDRSoft, Kirk, Lee, NIK, OnOne, Really Right Stuff, Singh-Ray, Tiffen, Wimberley and more.

Which tools to use and why is both science and art. Some hardware tools are used to stabilize the camera and lens for long exposures. Some hardware tools are used to stabilize the camera and lens while allowing motion on the X and/or Y axis. Some hardware tools are used to alter the light before it reaches the film or digital sensor. Some software tools are used to "stitch" digital images together to create panoramic images but most software tools are used to alter the affects of light after capture by the digital sensor or capture by film scanning.

Over time I have accumulated many of these tools and while I have many to chose from, my approach to creating an image has always been less work is better. I almost always use a tripod with a ball head. I sometimes use a gimbal head. When I am composing the image, I start out by visualizing the image. I then mix science and art by assessing the lighting and it's affect on the composition. Sometimes I use a circular polarizing filter, sometimes I use a graduated neutral density filter and sometimes I use a reverse graduated neutral density filter but I use them all with the same purpose: alter the light to fit the composition. Sometimes I find that the images did not turn out the way I wanted  and I will use software tools to try to alter the results. When using the software tools, I try to make changes using the raw image editors, filters and processors first. If the image is still not where I want it, I then use the post-raw editors, filters and processors. One thing I am not very good at is remembering to make notes about what filter (if any) I used when capturing the moment in camera. Sometimes I can look at the image and figure out what I did but when I am doing my best work, I can't tell if I used a filter.

Anyway, if you have read the blog update this far, here is your pay-off. The images I am spotlighting today were all found on one of two groups on FlickR. Some images were found in the group "LEE Filters" and some were found in the group "Singh Ray Filters". All demonstrate both the science and art of using a filter to create a memorable image.

Fire on the Horizon, Dante's View, Death Valley National Park

Two weeks ago, on an overcast afternoon, I went to Dante's View in Death Valley National Park hoping for some drama at sunset. When I got to the parking lot it was cold, windy, hinting at rain and not very promising. I hiked out to the view to look things over. I did not have my camera because it was looking more like "dinner time" then anything else. I wandered around considering what I would do if the sun would/could break through. I had my choice of were to work because with the clouds, wind, temperature and the appearance that rain was imminent, it was very empty and only one other person had a tripod and camera (and he was leaving as I walked by him).


It was my first visit to Death Valley National Park and it was to be my last sunset in the park for a while. I looked around for a few minutes and noticed that the earth at one saddle in the trail was a rich red color and would make a nice foreground. I hustled back to the car realizing that I was losing what little light there was, grabbed my gear and hustled back to the saddle. This image is one of a few that I created on the saddle before moving out to a point that looked more directly west (this image is actually oriented more to the north).




The sunset opportunity did not turn out like I hoped but I ended up creating several images that I really like. As I type this I am struck with the thought of what I would have missed if I gave up and headed out to find dinner.


Image particulars: Canon 5D MKII, Canon EF 16-35mm f/2.8L II USM at 16mm, f8, 1 second exposure, ISO of 100 and B&W Circular Polarizer. Post processing included Adobe LightRoom 3, Photoshop 5.1 and NIK Viveza 2.
