i want a polaroid camera

Polaroid cameras almost completely faded into non-existence with the advent of the digital camera, but surprisingly enough, they are making a comeback in some of the off-beat artistic photography. Actually for some people, Polaroid never left. I had a Polaroid taken of me at a restaurant in Taiwan—a place where they liked to hang customer photos on the wall. I was amazed at seeing a Polaroid camera still being used and thrilled at seeing the photo develop right then and there. The last Polaroid I appeared in featured a cardboard cut out of Ronald Reagan (current President at the time) in front of the National Air and Space Museum.

I found a spectacular stop motion animation on youtube made from 987 Polaroid frames, shot with a Canon camera without any computer manipulation.



I like how Process Enacted (above) is a meta-movie: a movie about making the movie itself. This reminds me, I have yet to see Adaptation, which is supposedly a movie about making the movie Adaptation. It brings me back to some of my undergraduate computer science classes where we talked about reflection: when a program examines and modifies itself while it is running. (Computer science is really more about philosophy than it is about science—more on that in my next post.)

If anyone wants to unload a 1970s-era Polaroid SX-70, 1980s-era SLR 780, or an 1990s-era SLR 690 camera, let me know! Oh and despite the song telling you to "shake it like a Polaroid picture," don't shake your Polaroid pictures :)

headshot: my first production photo project

The following post is a compilation of notes from my first production photography project. The goal was to take a headshot, appropriate for a reporter, but without access to either a studio or a light kit.

Not having access to a studio and never doing a headshot before, I turned to the web to do some research on what I could do. Photo.net had a good article on portrait photography, particularly the section on Stealing a Location.
What if you don't have a big open space with diffuse light and a neutral background? Steal one. If you live in the United States, a vast open space with light pouring in from expensive skylights is as close as your nearest art museum or university. With a 200mm lens set to f/2.8, the background will be thrown out of focus.
Unfortunately, most of the museums in DC do not have windows at all -- neo-Classical architecture is all about columns. There is one Modernist museum in DC though, I.M. Pei's East Building of the National Gallery of Art. The East Building has an atrium with pink marble walls (really a light gray limestone with a warm hue) and is topped with pyramidal glass skylights, which are screened by aluminum rods to reduce the sunlight. The photo below is a picture of the wall with light projected from the skylight, with shadows from the screen of aluminum rods appearing as fine vertical lines.

National Museum of Art East Building, atrium wall

Cool light pattern on the walls -- I'm guessing that was an intentional effect by the designer. My intent however was to blur the walls by setting the camera to a wide aperture (smaller f-number) so the patterns in the stone, the joints, and the light patterns become non-discernible and non-distracting but provide some variation in the background so that it's not just flat gray. Something like in the following photo.

National Museum of Art East Building, blurred atrium wall

The shoot was scheduled for a sunny afternoon to get the most light coming through the skylights. I arrived early to take some test shots on my own to check the light levels at specific locations in the atrium. I found the best lighting was not on the ground floor lobby, but rather on the highest bridge across the atrium. The bridges blocked some of the light from reaching the ground floor, so it appeared slightly darker compared to being on the bridge where it was as close to the skylights as we could get. Plus, the highest bridge in the atrium led to an empty/closed exhibit space so there was no foot traffic at all on it.

I put so much energy into light, background, and color that the camera settings seemed relatively simple. I used a 50-150mm f/2.8 telephoto zoom lens on my Canon Digital Rebel XT (equivalent to a 70-200mm on a full frame camera). Using the longer focal length of a telephoto lens results in flatter perspective, which generally results in more flattering portraits and better background blurring. I set the camera to ISO 200, evaluative metering, aperture priority mode, and set the aperture at f/3.5. The shutter speeds the camera was choosing (around 1/500 sec) seemed to make sense and the test shots looked fine. Lastly, I put the camera in continuous shooting mode so the camera would keep snapping for as long as I held the shutter release button down. I like snapping three or so photos at a time to account for changing facial expressions.

After meeting up with J, we started with a session of about 50 photos. I was fortunate that she handled all the things I knew nothing about: hair, wardrobe, and makeup. In addition, she had a good vision of what she wanted. I had a good general idea of what a headshot for a reporter should look like, but I didn't know how to direct the poses to get to that point, so one could say J self-directed her poses. After the 50 photos, I fired up the laptop to start looking at what we had. (The camera's LCD screen is just way too small to tell if the focus and details are correct.) After narrowing the choices down and seeing any quick improvements we could make, we went back out on to the atrium bridge and shot about another 50 frames. Back at the laptop, we found one that stood out from the rest and it ended up being our final selection. All in all, it took about an hour -- much faster than I originally thought it would take.

Later back at home, I tried a few crops and decided on a square crop. I experimented with adjusting some of the levels and the contrast/brightness, but I found that I was happy with the original exposure and that the image looked best without any additional post-processing. The below photo is the final result.

Headshot
83mm focal length (133mm equivalent on a full frame)
f/3.5, 1/400 sec, ISO 200, handheld, no flash

Lessons I learned from this project: (1) light and background are the dominating issues when taking portraits outside of a studio, (2) I need to pay more attention to poses and expressions to eventually get better at directing, and (3) bringing a laptop to location is a great way to check results and make sure everyone is happy before leaving.

In a broader sense, I'm realizing that photography is very much about proper planning and attention to detail. The smallest shadows make a huge difference in the end result, but one has to be able to recognize issues and then plan and/or react accordingly to resolve them. Strangely enough, I'm carrying lessons from software engineering (my day job) into photography. Sort of makes sense as the smallest of software bugs can create the largest problems. Pay attention to the user/customer's needs, address the greatest risks first by experimenting/prototyping to understand them well enough to mitigate them, plan on at least two iterations to end up at the final product, while re-evaluating after each iteration. Thankfully, digital photography lends itself well for quick feedback, making iteration feasible :)

non-square format

Ok, so not everyone likes the square format. I'm not saying that the square format is better than other formats, I'm just saying the square format is novel and it works well in certain circumstances. Below are five more photos from Arlington Neighborhood Day in the more traditional 3:2 format, something you'd normally see on a 4 by 6 inch print.

square format

Most digital photos are taken at a 3:2 width to height ratio, same as on a 35mm camera. However, some cameras such as the medium format Rolleiflex and Hasselblad (used by Richard Avedon, Irving Penn, and Diane Arbus, among many others), as well as the old consumer Polaroid produced a square image. I find the square image pretty novel, but I can't plunk down the insane amount of cash for a square format camera, so I've been emulating it by using a square crop on my 3:2 originals. The square format seems to have a few advantages: (1) it never needs to be rotated 90 degrees, (2) it works really well for portraits, and (3) it surprisingly captures background really well.

Below are some of my square crops from Arlington Neighborhood Day 2007. Click on the photos to leave comments if you'd like. The rest of the photos, square or not, are in my Neighborhood Day Parade photo set.

7008
30mm, 1/160 sec, f/8, ISO 200, aperture priority mode

7211
30mm, 1/640 sec, f/5.6, ISO 200, manual

7229
30mm, 1/640 sec, f/5.6, ISO 200, manual

7291
30mm, 1/500 sec, f/5.6, ISO 200, manual

7316
30mm, 1/500 sec, f/5.6, ISO 200, manual (the top of this photo is slightly overexposed)

7356
30mm, 1/500 sec, f/5.6, ISO 200, manual

7408
30mm, 1/500 sec, f/5.6, ISO 200, manual

7429
30mm, 1/500 sec, f/5.6, ISO 200, manual

7477
30mm, 1/500 sec, f/5.6, ISO 200, manual

I didn't have a zoom lens with me, so the crops were almost a necessity to get better aesthetics. Being able to clip away most of the overexposed sky in these square crops also helped to save/improve a number of the photos in the set. In afternoon sun, it's easy to end up either with an overexposed sky or an underexposed subject. Some more research is in order to find out how to get it right.

a reason not to use the flash

Let's take a look at two photos and compare.


My photo, victim to another camera's flash. Notice the performer wincing away from the flash as well.


My photo as I intended it, illuminated by firelight.

The electronic flash does have its place though. Counterintuitive as it may be, the best time to use the built-in flash on a camera is during the middle of the sunny afternoon. The flash works well to fill in shadows under a subject's eyes or a shadow cast on a subject's face by their hat.

As always, there are no hard and fast rules. Sometimes the flash is the only option at night when there is no other light source but you need/want to take a photo of something directly (up to about 10 feet) in front of you. Better to have the photo and have it look a little odd then not to have the photo at all.

flights of fire

Went back to get some more of Artomatic and I ran across some fire dancers from two troupes, Flights of Fire and Capital Fire Arts.

I'm really happy with the photos below. I cherry picked my favorites from the set, but trust me, it took many frames to get these. I like how the exposure turned out (I like my night skies really black), and I was pleasantly surprised at the how the skin tones turned out too. In many of the not-so-great ones (not shown), the focus was really off because I have a hard time seeing through my viewfinder when there's not a lot of light. I use manual focus when it's dark because the auto focus gets really confused when there is not enough light or not enough contrast in the frame. I was also taking three or four shots at a time to capture the fire when it got close to the performer -- that was the only way they were going to be sufficiently lit.

The following photos were taken with a fixed (no zoom) Sigma 30mm/1.4 lens on a Canon Digital Rebel XT, handheld, no flash, in shutter priority mode.

reflections of art

I took these photos at Artomatic, this year in Crystal City in the building previously occupied by the US Patent Office. Instead of taking direct photos of the artwork, I tried for a more indirect approach, trying instead for reflections of art. Click the photos to view more photo properties and/or to leave comments in flickr.

Reflections of Art
My favorite one from the evening.

Reflections of Art
Ran into a friend there, managed to place her into this more abstract shot.

Reflections of Art
I liked being able to focus on an individual piece in this one.

Reflections of Art
I liked having both glass and mirror reflections in this one, but I couldn't get the composition to look quite the way I wanted it to.

Self Reflection
Self-Reflection. I liked the texture details in this one. (Click on the photo, All Sizes, then Original to see the details.) Wanted to try for a slightly slower shutter speed to brighten the photo a bit, but this one seemed to capture my late-night, end-of a long week tired mood fairly well :)

bridges of frederick county

Who knew that there would be covered bridges in the DC area? I took the following photos on a recent Washington Photography Meetup outing, (Covered) Bridges of Frederick County (Maryland). If you're interested in seeing these bridges for yourself and maybe taking your own photos, we followed the Historic Covered Bridges Driving Tour provided by the Tourism Council of Frederick County. Just be sure to take your eye out of the viewfinder every once in a while to check for traffic approaching the bridges. :)

james nachtwey on tedtalks

About this time last year, I wrote in my [2006 Cherry Blossom] festival wrap up about a film screening I attended for War Photographer, a film that featured photojournalist James Nachtwey. About this time last week, I came across a talk and photo slideshow given by James Nachtwey on TEDTalks, where TED stands for Technology, Entertainment, and Design, a conference held in Monterey, California.

Some of the photographs in the slideshow are graphic images of suffering, however the photographs are showing reality. Nachtwey uses photographs for all its power, to bring our eyes and attention to a place that we normally don't see and moving people into action. It amazes me how Nachtwey can cover the stories and remain sane. Just watching the retrospective slideshow of his work, I can only imagine how strongly the images would burn into my memory and my persona if I were there in person like he was.

cherry blossom snow photos

When I originally scheduled the Cherry Blossoms at the Tidal Basin Meetup for my photography meetup, I was anticipating a normal spring sunrise: 50 to 60 degrees, maybe a little breeze. The hope was for a clear sunrise to get some really good light out on the blossoms and to perhaps beat the tourist crowds by a couple of minutes. Washington weather being what it is (wacky), conditions ended up being cloudy, snowing, and 32 degrees, with a wind chill factor of 24 degrees.

Seemed like the perfect morning to stay in and stay warm, but I'm glad I and a dozen-plus members made it out to the meetup. How often does one see snow on cherry blossoms?! By the time we wrapped up, my fingers were so cold, I was barely able to press the shutter button. Those readers who are familiar with the bone-chilling precipitation that falls in DC, be it snow or rain, you know what I'm talking about.

The results were well worth it though. Below is a selection of three cherry blossom photos taken near the paddle boat dock (across from the Jefferson Memorial) on the Tidal Basin and three tulip photos taken at the Tulip Library. A few more selections are available in my Cherry Blossoms (Snow) Meetup photo set and the Washington Photography Meetup photo pool on flickr.

Photography Assignment #2
due Saturday 20 January
This is an easy one -- pick one to three of your favorite photos you took over the holidays or these first few weeks of 2007 to share. You are welcome to submit photographs that capture the essence of the holidays, the holidays in your hometown/travel destination, or photos that you took for fun during the holidays that you want to to share with everyone else. The resulting collection should be an interesting mix of photos that show how us DC folk spread out, geographically and perspective-wise, during a typical holiday season :)

Photography Assignment #3
due Tuesday 30 January
The abstract topic of the month is "winter." What does winter mean to you? Black and white scenes? Black overcoats all around? Cold rain? The bread, milk, and toilet paper frenzy at the grocery store before a snowstorm? The interpretation is open-ended and left up to you, the photographer.

Monuments and Memorials in the Snow
On the first day it snows with accumulation of at least 1/4 to 1/2 inch.
RSVP Yes to this event if you want to receive a "go / no go" email to meet up at the Vietnam Veterans / Korean War / WWII memorial when snowy conditions are pending. Be sure to click the event description for details as to how this event will work since we don't really know when it will snow and accumulate at least a quarter to a half inch.
