Photographing a live drama performance




In the past, I have photographed drama productions using high-speed 35mm film. The results were prone to a great deal of grain and visual noise. Last week, I shot a drama production using the Canon 5D mk II DSLR and the results far exceed anything I could do with film.

During the actual performance I used ISO 12800 with no flash. During dress rehearsal, I had freedom to use electronic flash and shoot from different angles not possible during the live performance. I setup a remote flash bounced off of a 36" reflector; this provides a larger and softer light source. Because the flash was being bounced off a reflector, I configured the flash for higher intensity output than normal/default.

The images shown here provide comparison of shooting with flash and without. The primary light source is always the spotlight. The flash provides fill-light in the shadow areas.

Notice the shadows cast on the wall. Both the spotlight and the flash create shadows. (Here, the shadow from the spotlight appears low on the wall because the spotlight is mounted near the ceiling, probably eighteen feet above the floor.) The shadow from the flash has a soft edge while the shadow from the spotlight has a hard edge. This difference is due to the differing sizes of the two light sources. The bounce flash is giving me a light source 36 inches in diameter at a distance of 25 to 40 feet. The Spotlight is maybe 10 inches in diameter at a distance of 25 feet. Both size and distance of a light source directly effect the hardness/softness of the light.


Neither approach is better than the other. Sometimes you want hard light. Sometimes you want soft light. It can be nice to have both.

Pixels (part 2)

With the information in my blog post entitled Pixels (part 1) [how-many-pixels-part-1], you may conclude that 8x10 inch prints call for a 5 megapixel camera. That's generally true, but not entirely. It is possible to use computer software to artificially increase the number of pixels. Different software programs may perform differently. The general rule of thumb is you can double the number of pixels. So, you might print very good 8x10 prints though your camera only records 3 megapixels.

Maybe you just bought a new DSLR that records images up to 15 megapixels. Those 15 megapixel images may require three times more storage than 5 megapixel images. If you shoot
some pictures on Tuesday, intended for 11x14 prints, set your camera to record large size. If you shoot some pictures on Wedensday, intended for computer screens only, set your camera to record small size.

Pixels get a little weird when you move to television display. Pixels on a computer are square. A digital image that is 400x400 pixels will display square on your computer monitor. Not so on a television screen. Television pixels (defined by either NTSC or PAL standards) are not square.

Consider an picture aspect ratio of 4:3, meaning the picture is 25% wider than it is tall. Standard television (not HD) has a 4:3 picture aspect ratio. Yet the resolution is 720x480 pixels, which numerically seems to be 50% wider than it is tall. But rest assured it is 4:3 because each television pixel is taller than it is wide. (Take a very close look at a television and you can see this is so. It is more difficult to see on a HD television.) While pixels in a computer or in your camera are equally wide as they are tall (often called square pixels), pixels in television are taller than they are wide.

Fir branch under ice


Hiking in the white mountains of NH on Dec.1, there was no snow at the trail head, but eventually became a foot deep. Having made such a mistake once before (several years ago), I kicked myself for doing it again.

It was a long cold day, but there were rewards. In particular there were a few little streams that crossed the trail with small waterfalls only a few inches in height. The spray of water caused some interesting ice formations, including the one shown here. The fir branch was covered in ice, but the mossy rock beneath it was not, presumably because the movement of the water was enough to prevent freezing.

In retrospect, the choice of aperature plays an important role in the success of this image. Both the extreme foreground and the extreme background are slightly out of focus. However, I wish I had framed the image a bit more to the left to avoid the ice touching the left edge of the frame.

Sunrise and Fog

You might think this is a difficult exposure to make; it really is not. There are some really dark areas; there are some really bright areas; but neither is really dominant and so does not cause a problem for the camera's meter. Trust the camera with this scene and it will probably do a decent job.


There are two subtle things I would like to point out. First, I intentionally positioned myself such that the full sun was not beaming directly into the camera. The sun is partially obscured. Second, given a choice between the highlights and the shadows, the highlights are more important. So, to be safe, I under-exposed by maybe 2/3 stop to insure that detail in the fog is retained.

The Third Sheep






Often, I will plan to be at a certain place at sunrise in order to photograph with the warm sunrise light. However, on this particular day, the weather forecast called for cloudy and cold. So I did not leave my motel room until 7:30am and only then found that some sun was dodging through the cloud cover.

Looking at a map, I chose some back roads to explore. The first road followed a river, but I saw nothing that caught my photographic intentions. Then I drove off through some farmland and stumbled upon these sheep, grazing on a hillside covered with frost. Atop the hill, the sun was catching the orange leaves of autumn maple trees. At the bottom of the hill was a still pool catching reflections.

Just a bit of sunlight on the trees, combined with general cloud cover, the conditions were fleeting and did not last. I captured about a dozen images; this is one of my favorites.

Where is the third sheep? Uphill, further toward the trees, out of frame ... but appears in the reflection.

.



I created this image about one year ago on color transparency film (Fuji Provia F), medium format 6x6, using the venerable Bronica SQA. (That was the last time I used film.) Scanned to digital at 4000dpi, the digital image is a bit more than 70 megapixels, allowing a life-size 36-inch print. At 33x33 inches, this image was printed on a canvas gallery-wrap, stretched on a wood frame much like a painters canvas. The image wraps around the edges, 1.5 inches on every side, such that the face of the print is 30x30. This is the second canvas gallery-wrap I have printed this year. The first was a panorama, five feet wide.

What I want to share with you is a comparison of three different print types.

Printing on canvas has become very accessible these days, available from many vendors. Upload the digital image to the vendors website, choose your options, and provide payment. I chose Artistic Photo Canvas, having seen the excellent prints first hand. Of course, canvas is remarkable for the texture. APC uses only a high-quality cotton canvas and provides a protective clear coat over the final print. However, be aware that the maximum black density (Dmax) and the highlight intensity cannot match printing on more traditional photo papers. The overall contrast is therefore reduced. Although APC boasts one of the highest Dmax available on canvas, it is poor compared to traditional photo paper. None-the-less, it is an impressive way to display a photograph.

Then, I had the same image printed on metallic photo paper. This print is craaazy! The highlights in the image have a 3-dimensional quality that seems to exceed the 2-dimensional nature of the medium. Compared to a traditional photo paper, metalic paper may exhibit some minor loss in subtle color gradation; but holy cats, man, it is stunning. It is not suitable for every image; for example, I would not recommend metallic paper for portraits. To get the most from a metallic print, ensure good illumination; without good light, it tends to look like any ordinary print.

Seasonal fun


I love autumn in New England. The mixed hardwood forests can produce a magical display of color. So, I have to post some nice seasonal image.

However, while I am sharing here an image from New England, this particular image is not peculiar to the region. This image is simple seasonal fun that happens all across the country. This was a simple grab shot; driving down a rural road, I saw this beside the road, stopped the car, took a handful of photographs, and then left.

The artistic vision here is not my own, but someone else's. I can only claim good composition and exposure. The one trick here regards the white fence, which was overly bright relative to the rest of the scene; so I underexposed the image by 2/3 stop and later adjusted the curves in Photoshop.

An Evening with Photographer Joe Buissink

Just returned from seeing a presentation by photographer Joe Buissink. I confess Joe shattered any pre-concieved notions I held about high-paid celebrity photographers. He shared many images and his passion for capturing fleeting moments between people.

He still shoots film and his clientel are people who seek that and appreciate that. He primarily shoots available light at ISO 1600 and 3200. His images tend to be less grainy than most of us associate with high ISO. His film processing lab will visually inspect the film during development, empirically pushing the development until the density is good. This avoids low density low contrast, which requires compensation during printing and thereby incurs enhanced graininess.

Joe seeks emotional moments, not necessarily perfect sharpness or perfect composition. His pitch to prospective clients is more about himself and his passion. He tells the stories behind the images that you would not know from the image alone. Once people are hooked on his passionate approach, they tend to give him less direction and restrictions. He typically does not have to align himself to a required shot list.

Joe does more than just weddings. He recently completed work on a book about autism and the images comminicate a compelling joyful story. He photographed Stephen Spielberg's birthday party, Christina Aguilara on tour, and the closing episode of the Frasier television show at request of Kelsey Grammer.

The Buissink approach to photographing people is eye opening (to me anyway) and it was a truly enjoyable evening. However, it is no secret that he caters to very wealthy people and the cost for his services is adjusted to their financial means. I personally do not know anyone who can afford him.
