Bob Crum First, a repeat call for photographers. The Fillmore Art Commission is planning an Art & Photography exhibition next May 1–5, 2019. The exhibit presents an excellent opportunity for you to display your 'Fine Art' photographs. For planning purposes, it's important to hear from all Fillmore photographers who might be interested in participating. Reply to the email address below and write “I'm interested” in the subject line. Moving along, for many years I've been photographing the Kern River from Brush Creek down to where the river exits the canyon below the powerhouse. Why you ask? First, rivers are fascinating. Rivers have unique personalities. Flow rates vary greatly. Sometimes a roaring torrent of water. Other times a lazy, slow-flowing river. Shoot it a hundred times, yet it's impossible to photograph the same river twice! This stretch of river is replete with huge boulders in the river and on the banks. The topography of the river lends to magnificent, though often challenging, photo ops. The interaction of the water and the obstacles in the river is fascinating to watch and photograph. Two reasons for a trip to the Kern. Shoot and create a photo essay of the Kern River at low flow stage. Second, I developed a sudden and unexplainable itch to drift the upper Kern from Brush Creek to Kernville in an inflatable kayak. Along the way shoot photos and video thereafter create a 'docujourney', a documentary of the journey. Being recently gifted with an inflatable kayak expedited the idea. Checking the charts, I noticed that the data indicates a flow rate of 150cfs (cubic feet per second). However, I couldn't relate the data to the actual volume flowing. Was the flow sufficient for navigating the river in a kayak? I had to go and see. Alas, the itch will have to wait to be scratched because 150cfs is woefully insufficient for making such a float trip practicable. C'est la vie. Additionally, I needed to shoot some photos for future photography lessons. The river is another excellent subject for showing the difference between shooting rapids or waterfalls at a very slow shutter speed or at 1/500th of a second. A two-second exposure gives the water flow the appearance of silk or cotton candy. Conversely, a fast shutter speed stops the action showing the flow more realistically. The photographer has the option to create the image as desired. I acknowledge that many photographers consider the silk look a more 'artistic' rendering of a waterfall. I'm not fond of that 'look.' I prefer a roaring waterfall captured to illustrate the full fury of the rushing water. However, I've discovered that most times rushing water is beautifully portrayed with a shutter speed between the two extremes. Realistic photo or manipulated as a 'fine art' image, it's merely a matter of preference. More importantly, this ability to create as desired is what makes photography a tantalizing and very fulfilling medium. More importantly, having to make numerous creative decisions continually stimulates the mind keeping the brain healthy! I can't cite scientific studies to substantiate this declaration, but given the status of my exemplary and sound mind gives the theory a high degree of credence... IMHO. Photo of the week: Another cow! (sigh) The photo was captured off Kern Canyon Road on the way home last Sunday. The... ahem... river 'cowflection' grabbed my attention. Another example of the power of observation! Saw her, stopped and captured the photo just in time. Five seconds later she disappeared behind some trees.
