The Blog: See what
Sigma is saying.

10.21.2014

Welcome to my new, bi-weekly photo “dog blog” celebrating canines and cameras. Here I plan to write about dogs, photography, and life. Specifically, I hope over time that over time this column accomplishes three things:

  1. Shares ideas about way to photograph your pet
  2. Documents the growth of our new Labrador retriever puppy from the first week at home onward, as well as showcasing other dogs
  3. Reflects on how photography of our “best friends” can teach us about life, particularly examining how dogs influence our lives and, recursively, how we affect theirs.

This first installment is full of joy and replete with sadness. While my family and I are elated with the arrival of our new ‘fox red’ yellow Labrador retriever, Rowan, we are also grieving the recent loss of our nearly fourteen year-old friend, Maple, our first yellow Lab.

*Please note that I ADDED the slight vignette in these images in Photoshop/Lightroom.

Earlier this year I took an expedition into the giant sand dunes outside of Dubai to shoot a fashion editorial for Zink Magazine. This was a shoot I had been anticipating for quite sometime, as it was the type of work I always dreamed of shooting. I would be in an exotic location with an incredible team on my side, beautiful model, and freedom to create striking images. It truly was a dream shoot made into a reality.

On the first day of shooting we took the vehicles deep into the dunes, passing camels and leaving the nearest town and signs of life far behind.  As we approach the gathering of dunes I was amazed as they towered like mountains above the SUVs. Seeing the model first stand into front of the dunes, she appeared like a speck before their grand size.

As we stepped out of the car, however, I realized a major obstacle to be tackled. Perhaps my dream shoot wouldn’t be a simple and picture perfect as I had hoped!

In late August a Hurricane off Mexico sent giant waves to California. The surf spots that are open to the south-southeast swell angle were extra large to extra extra large. The morning the swell hit I ended up shooting at the Wedge, a surf spot in southern Newport Beach in Southern California. This was a historic swell and will be talked about for years and years and never forgotten by those lucky enough to experience it in person. These are some of my favorite images from that session, I hope you enjoy them.

The Sigma 120-300mm F2.8 DG OS HSM | S really worked perfectly at the Wedge at this size. I brought a 1.4x teleconverter and longer back up lenses but never had a need for anything else.

Big drop on one of the bigger waves that day. If you look close you will see this guy’s back foot is not on the board but is about two feet in the air.

What a difference a couple of years makes!

Two years ago, we were gearing up for PhotoPlus, just days after the announcement of the Sigma Global Vision at photokina 2012. We were preparing ourselves for discussions and briefings to explain the philosophy behind the three new lines being offered.

At that time, many photographers and technical editors were confused as to what Art, Sports, and Contemporary was meant to convey in a lens name. We spent a lot of time that fall explaining the way that Sigma is rethinking lenses and how this relates to the three new lens markings.

The Sigma 150-600mm F5-6.3 DG OS HSM | Sports lens is one of the newest lenses in the Sigma line, announced at photokina 2014. This lens is designed for exceptional outdoor performance.

Shortly thereafter, though, the first of the new Sigma lenses, the 35mm F1.4 DG HSM | Art lens was released, and almost overnight, the conversations changed. Photographers and editors around the world were blown away by the build quality, and more importantly, the total image quality of this new Sigma, full-frame, fast-aperture wide prime. People realized that this new lens, the original Art lens, was something quite special. It defined the Art category and heralded a new era for Sigma under the guidance of new CEO Kazuto Yamaki. It was the perfect proof of the promise of the the Sigma Global Vision.

In part one we discussed the use of polarizers and solid neutral density filters.  So what other filter should you have in your bag? The answer is: the graduated split neutral density (ND) filter. What do they do?  They allow you to balance the light on the foreground with the tonality and brightness of the sky.  How?  The filter is split in half with the top being much darker and the bottom half clear.  The dark area is graduated down towards the middle, which allows you to darken the sky and better match it up with the tonality of the foreground. They generally come in 2 styles; one with a hard edge and the other is often referred to a soft edge.  The hard edge has a clearly defined line where the soft edge is more graduated.  This is the one I prefer and use most of the time. A variety I also have is called a reverse graduated neutral density filter (both made by Singh Ray) where the darkest area is towards the middle which makes it particularly useful as the sun comes up or is about to set.  It is best suited for situations where you have a pretty level horizon without many protrusions into the sky.  Below is an example of both and they typically come in increments from 1stop all the way up to 5 or more.  Most practical are the 2 and 3 stop versions from numerous manufacturers.  Notice that I am not recommending any screw in type as what you want to darken is seldom in the middle of the frame.

This simple answer is absolutely yes!!!  While they may not be as important as they were in the film days, there are still some filters that are absolutely necessary in today’s digital age.  I will break this blog up into two parts so I can cover this topic in depth.  Part 1 will cover circular polarizers (CP) and solid neutral density (ND) filters.  Part 2 will cover graduated neutral density filters as well as some additional specialty filters you may want to have in your bag. Let’s start with the circular polarizer.  Truth is I don’t use  a CP as much as I used to.  The dynamic range of modern digital cameras has greatly improved over slide film so I only use my CP when I am around water to reduce/eliminate glare. I went out to photograph waterfalls this spring in Pennsylvania.

Of the three main variables relating to creative and artistic control on DSLR and compact interchangeable cameras–aperture, shutter speed and ISO–aperture control, is for many beginners, the most difficult to grasp. Have no fear, we’re here to help! Learning how and when to select a wide or narrow aperture unleashes the creative and expressive potential of your camera’s lenses, and puts the control firmly in your hands.

These two apples were photographed with the Sigma 18-35mm F1.8 DC HSM | A lens zoomed to 35mm with an F2.8 aperture for shallow depth of field. Notice how just a sliver of the leaf and near apple is on the focal plane. The front apple is about a foot from the lens, with the farther apple nine inches behind. The back wall with the very soft shadow is ten feet from the camera.  1/40 F2.8 ISO 400, continuous lighting.

The back wall with the very soft shadow is ten feet from the camera. 1/40 F2.8 ISO 400, continuous lighting.

And here is the same image captured at F/16, a much smaller aperture. The area of the aperture circle is much smaller, so a longer exposure time of 8/10 second is necessary to give an equivalent exposure. Notice how much harder the edges are on both the far apple and the shadow on the wall with the smaller F/Stop.

And here is the same image captured at F/16, a much smaller aperture, with the focus again exactly on the leaf of the front apple. The area of the aperture circle is much smaller, so a longer exposure time of 8/10 second is necessary to give an equivalent exposure. Notice how much harder the edges are on both the far apple and the shadow on the wall with the smaller F/Stop.

Quite simply, the lens aperture (also known as the F/Stop) controls the size of the opening inside the lens that light will be passing through during image capture. At a given focal length and focal distance a wider aperture will have a shallower zone of sharp focus than a smaller aperture.

Almost everything we do in life is a choice.  How we express ourselves, how we see objects, how we create art, all of these elements, although may be intuitive to our nature, are also choices we make.

In regards to photography, we may choose a certain kind of subject to photograph.  Some of us prefer to photograph landscapes or children or weddings.  Whatever the subject, it’s a choice we make, and in making those choices, we are creating a style and a look to our work.

There are several other style choices that I want to talk about in this article.  They include lighting, lenses, angles, locations, props and camera settings.

Lighting is a style choice.  How we see light and then use it in our imagery is a choice we make.  Some of us prefer a Low Key image with very dramatic lighting effects.  Some prefer High Key lighting like these images of Courtney and her family.

My annual trip to Alaska in late July to early August usually means big skies and great light, schools of salmon in the rivers and creeks and coastal brown bears, lots of cubs, and almost unlimited photo opportunities. This year we were treated to two full weeks of sun and clouds without a single rain shower. These are some of my favorite moments of the trip with some technical notes and stories behind the images.

This mother brought her tiny spring cub out in the evening to fish for salmon but the bear didn’t look much bigger than the fish they were after.

Using the 300-800mm lens for bears in good light you can just sit back and relax waiting for the right moment knowing that you have the right lens on your camera, not too long and not too short.
