Black And White Challenge

Two weeks ago I was challenged by friend and photographer Jerry Dodrill to post 5 black and white photographs on social media over 5 consecutive days. As I am not known for shooting much black and white, I dug back into my archives to see what I had. From that selection, I chose five photos from a variety of subject matter (landscape, wildlife, and architecture) that spoke to me more as fine art than editorial photos. Here is my selection collected together, along with a short synopsis of each.

Day One

Dawn breaks over Banner Peak and Thousand Island Lake, Ansel Adams Wilderness

I shot this last year on my attempt at the John Muir Trail. Thousand Island Lake is a beautiful location in the heart of the Ansel Adams Wilderness. This was a dark, moody, stormy morning, and during a brief pause in the torrential downpour, I braved the elements and scrambled out of my tent to capture Banner Peak with the lake below. In order to convey my feelings at the time I shot it, it seemed like a perfect candidate for a B&W conversion.

Day Two

This shot is of the Mesquite Dunes outside of Stovepipe Wells in Death Valley National Park. I shot this fairly wide (21mm) as I was standing on the foreground dune. Those who have photographed a lot of sand know that you can’t just back up to reshoot – you’ll end up with a photo full of footprints! Black and white allowed me to add contrast into the sand ripples along the crest of the dune.

Day Three

Four american white pelicans line up, all of them fishing at the same time. There was a nice symmetry to this image, which was calling very strongly to be rendered as a black and white fine art photograph.

With this photo, I’m switching focus to birds (hey, birds can make great B&W too!) I was shooting a group of American White Pelicans and was waiting for that perfect, synergistic moment. Finally they all ducked down for fish at the same time (the white pelicans tend to be much lazier when eating as compared to the California Browns who are constantly dive bombing their food). I caught the moment and new it would make a nice pano crop – a conversion to a high-key black and white was icing on the cake.

Day Four

Church and cemetery, Great Smoky Mountains National Park

This image is a little different from my usual fare. Quite a few years ago, a friend and I were hiking through the woods of Great Smokey Mountain National Park. It was a still, crisp November day, and we were utterly alone with the trees. Throughout the day, we had been getting a very creepy vibe. Unlike the wilderness of the west, these forests are littered with remnants of past civilizations – small mountain villages linked to other settlements only via walking paths. It almost felt like the ghosts of the past were watching our progress through their woods. Suddenly our trail opened up into a clearing with an old church, complete with cemetery and 100+ year old headstones. When I took this photograph, I knew I wanted to try to convey that feeling that we’d been getting all day. A black and white, high contrast conversion was in order.

Day Five

My final shot is another B&W dune photo from Death Valley. This time I kept the contrast and the clarity low, to emphasize the soft buttery texture of twilight. What first attracted me to this spot was the three tall dunes in the background. I think they reminded me of pyramids off in the distance. I set about looking for a foreground. When I found layer upon layer of sand “waves” stacked up in front of the dunes, I knew I had my shot. I fell in love with the way the light moved across the sand like it was a living thing. In order to remove all other distractions from the photo, I subtracted all color and let the interplay between the shadows and highlights define the photograph.

Why I’m Buying the Canon 7D Mk II

This week Canon finally released their long awaited successor to the very popular (5 year old) 7D. The 7D is one of my main workhorse camera bodies, used primarily for bird and wildlife photography.

Canon 7D Mk II

Here is a rundown of why I have already pre-ordered the Mk II. These are the features that are most important to me based on the type of photography I will do with this camera.

Most Important Features

  • APS-C sized (cropped) sensor.

The smaller size of the sensor on this camera is what sets Canon apart from many competitors, who seem to be pushing the high-end pro-sumer market to full frame cameras. Canon still sees a space in the lineup for APS-C sensors, and so do I.  I will primarily use this camera for action (wildlife and bird photography), so having the extra "reach" will be a big benefit to me.

This factor prevented me from considering the 1DX for wildlife work when it came out. Although that is a fantastic camera, I couldn’t justify losing the 1.6X “zoom” factor that a cropped sensor gives me. The 7D Mk II has a much higher pixel density than the 1DX (20 MP on 7D MkII vs 18 MP on the 1DX), which will allow me to capture more detail. In fact, if you compare the pixel density of the same area of sensor between both cameras, the 1DX only has just over 11 MP compared to 7D Mk II's 20 MP.

  • f/8 auto focus capability.  

This has been under-reported on, but is a huge feature for my use. Allowing auto-focus to work down to f/8 means I can pair my 800mm f/5.6 lens with a 1.4X tele-extender, which gives be an effective maximum aperture of f/8. This combo also gives me the 35mm equivalent of a whopping 1792mm, a distance I’ve never been able to use auto-focus with before.

Having this kind of distance flexibility to work with can get me closer to the action without spooking or antagonizing my target species.

Species like the endangered burrowing owl will become stressed if you get too close. If it is only watching you, then you are too close – it should be constantly swiveling its head looking skyward for predators.

  • Improved AF tracking (including low light) [65 all cross-type auto-focus]

There is nothing worse for a bird photographer than to patiently wait for your subject to take flight, only to watch the bird fly away as your camera is hunting for focus.  Having the best of class auto-focus will ensure my equipment will not be the one at fault.  In the future, I'll only have myself to blame!

Having so many auto-focus points for the camera to choose from means that the auto-focus algorithms can track a subject throughout much of the frame.  Cross points allow auto-focus on horizontal and vertical lines throughout the frame.  This means faster, more accurate focus seeking and tracking.

The 7D Mk II’s improved low light auto-focus tracking should make keeping focus locked on birds such as owls who take to the sky at dusk more manageable.

  • "Intelligent Tracking and Recognition (iTR)"

iTR is a new feature introduced with the Canon 1DX and has now filtered to the pro-sumor line. This employs a new RGB metering sensor which can detect and track moving subjects based on color, size and shape. Theoretically, this should help keep focus on erratic motion, such as flying birds. I’m looking forward to putting this to real world tests.

  • Improved high ISO performance

The majority of wildlife come out during the ends of the days, either in early morning or late evening.  Having a camera that can focus and capture images in this kind of light with relatively low noise will be a huge advantage.  While this camera probably does not match the low noise of cameras with a lower pixel density, it will be a big improvement over my 5 year old 7D.

  • Auto ISO parameters

Canon finally got this feature right, with many manual controls around how the metering will select the proper ISO for a given shooting condition.  I can now set a maximum ISO to use (which I'll set to the highest ISO I deem to have acceptable noise), as well as the minimum ISO. With this feature, I can also set the minimum shutter speed the camera will use before increasing the ISO in low light scenarios. Currently I manually set my ISO up or down as the situation calls for it, but I will certainly be using a limited auto-ISO range so that I don’t miss any critical moments.

Nice to have features

  • 10 fps shutter speed

I already have 8fps with the 7D, but hey, 10 is more than 8, right. All the better to help capture critical action like this:

A male white-tail kite flies past a female, which reacts to his close proximity
  • GPS

Sure, why not?  However, I will now have to be careful to strip out any location data from photos of sensive locations such as this:

The mountains of the easter Sierra Nevada glow red over the Sky Rock Petroglyph, just outside of Bishop, CA
  • Intervelometer

Nikon cameras have had this for years, so its nice to see Canon catch up.

  • Buffer depth (31 RAW vs 25 RAW in 7D)

This is a huge buffer! Having the ability to take 31 consecutive photos at 10 fps is pretty incredible. I’m not a big fan of spray and pray photography, but when you need to blast off a few, knowing that your camera won’t suddenly go quiet on you brings great peace of mind.

Right Tool For The Job – Full Frame Vs Cropped Sensor

Recently I was asked by a prospective digital camera buyer about my opinion on full frame verses cropped sensors. The answer is actually not very simple, so I thought I’d expand on my thoughts in this post.

For those who aren’t familiar with these terms, full frame refers to a digital camera that has the same sensor size as 35mm film. This became the prevailing film standard, and most of today’s digital SLR lenses use this size to calculate their relative lens magnification factor. A cropped sensor camera is a digital SLR that has a sensor smaller than 35mm film. These cameras use the same lens focal length scale, but apply an additional “magnification factor” to the 35mm numbers. For example, Canon’s cropped sensors apply a 1.6X magnification factor to lenses as compared to 35mm-sized sensors. If a full frame camera used a 50mm lens, the perceived magnification factor using the same lens of a cropped sensor camera is 50mm X 1.6 = 80mm. In other words, in the resulting photos, it appears as if the camera was zoomed into 80mm when using a 50mm lens on a cropped sensor camera.

So which is better? As with any tool, it depends on the job. I use both full frame and cropped sensor cameras regularly in my photography. When I’m shooting landscape, architecture, or macro, I typically use a full frame camera. My current workhorse is the Canon 5D MkII (now practically a dinosaur of a camera!), which allows me to use a full range of lens focal lengths, including my widest. In these shooting conditions, camera features such as auto focus and frame rate are not as important to me as pixel count and low digital noise. With this camera, I shoot from a tripod most of the time and work slowly and methodically through the scene, getting as much right in camera as possible.

The photo above is an example of using a full frame camera with a wide angle lens. Here my 17mm lens truly gave me the wide angle using my full frame sensor, instead of the appearance of a 27 mm lens (17 X 1.6) if I used a cropped sensor. I worked from a tripod, manually focused, and shot at ISO 100.

When I’m shooting bird and wildlife photos, I always use a cropped sensor. This gives my long lenses that extra reach, and cropped sensor cameras tend to have slightly lower pixel count, which allows for faster frame rate. My cropped sensor workhorse is the Canon 7D, which has my most important traits for these shooting conditions – fast auto focus and high frame rate. While low noise is always desired, here the highest pixel count is not as important, as wildlife and bird photos typically don’t end up in huge prints. Pairing this camera with a 400 mm lens allows me to handhold while photographing giving me lots of mobility. When I use it with my 800 mm lens, I get the equivalent of 1280mm due to the lens multiplication factor. This gets me in close to my subjects without needing tele-extenders, which reduce auto focus performance.

The photo above is an example of using a cropped sensor camera with a long lens. Using the equivalent of 1280 mm (800 X 1.6) allowed me to be far enough from my subject to not disturb it from its normal behavior. I was also able to shoot many frames per second to capture the perfect body and head position while the green heron was fishing.

Just as a carpenter wouldn’t just use one type of hammer, a photographer won’t resort to just one type of camera. If you are just dipping your toes into the world of digital SLRs, think first about what type of photography you’d like to explore first. That will likely help you list your desired features and point you to the right tool for the job.

Hiker And Halfdome

I created this photo on a backpacking trip a few weeks ago. I set out with a couple of friends, Frans and Mark, and our three day plan was to hike along the northern rim of Yosemite Valley from Snow Creek to Yosemite Falls.

I knew our best photo opportunities would likely be on the first evening. Snow Creek is located along the rim of Tenaya Canyon, directly across from the face of Half Dome. I had been here once before, and ever since that trip I had been visualizing the photos that I wanted to create there.

Primary on my list was a shot of a backpacker with the face of Half Dome looming high above. Half Dome is most famously viewed from the side, as most photographs of it are taken from the perspective of Yosemite Valley. In order to be successful, this photo had to have a few specific characteristics.

First of all, I knew I needed to use a long lens. I wanted to render the backpacker fairly large in frame, but also render the dome as large as possible. This meant that I needed to be close to the hiker and stack the layers of depth on top of one another, so that both near and far subjects would be large in the photo. Had I used a wide angle, the dome would be much smaller than in my vision.

Secondly, I wanted to shoot this in late afternoon with clear skies to the west. When the sun sets, its light moves all the way up Yosemite Valley and strikes the face of Half Dome, giving it a warm orange glow. On this particular day, I could have done with some clouds to the south and east, so that I’d get a little sky interest, but I worked with what nature gave me.

One thing I didn’t think about beforehand was the fact that the plateau from which I was shooting would be completely in shadow. This meant that in order to properly expose the cliff face, the backpacker would be too dark to clearly see details. After some experimentation, I decided to go with high contrast and render the backpacker as a detail-less graphic silhouette. I think this works very well in the final image, as it creates more emotional impact for the viewer. Those who travel this nation’s back country can easily see themselves standing in the photo, experiencing a glorious sunset.

Mark and Frans graciously volunteered to be my models, and I ended up choosing this photo of Mark as my favorite. In order to add more of the scene, I took additional photos of Half Dome and stitched them to the first shot to create a panorama. This really completes the scene, showing the entire cliff from which Half Dome emerges. We had a great (and cold) three days in the wilderness, and as I suspected, the photos I took from Snow Creek ended up being my favorites.
