Revealing Form, Texture And Shape

At the end of my photo class last week we finished a session on lighting people, then tried a quick experiment to see how light can be used to create texture.

My students worked with a medium softbox and a reflector and explored ways to reveal an interesting space around three small rings, and to reveal the detail in the rings. One of the keys was to realise how important directionality is as a property of light. We wanted soft light, but we still wanted to create shape and reveal form.

Good Work, New York

First, the subway stairwell handrail was broken, then a few days later it was repaired. Great.

See how easy that was? If someone knocks something over, consider putting the exact same thing back up in its place, and fast. Don't wait a decade, have meetings, politicize the process, and leave an open hole. Better yet: go ahead with putting up something significantly better -- but do it fast, like when the Pre-Parthenon was destroyed.

See? Art history has valuable lessons in it.

Change and Turnover

I haven't really paid attention to the many people who say the decade is ending. I tend to think that since we start counting with "one" and not "zero" the first year of the millennium was 2001. Meaning 2010 is part of the decade, not the start of the next one.

As 2000 approached, I kept telling people: "Nope. Not the start of the millennium. That will be 2001." I said it a lot. Then I won a photography contest, and the prize was a "Kodak Millennium 2000" camera.

New Friends Are Silver, Old Friends Are Phallic

I tend to snap away with the iPhone. Anything on the ground or wall is fair game. Sometimes, however, I'm not sure what to do with these images. Today, a pairing: an image in gold found on a Manhattan wall, an image in silver from The Bronx.

Advanced Seriously Fun Photography, Week 2

In last night's Advanced Seriously Fun Photography class our main goal was to really tune in and see light. We looked at the qualities of light, then tried to apply that to how the camera sees light. A few ideas became obvious right away: because the eye opens up when it looks at dark areas and closes down when it looks at bright areas, usually the camera records a more contrasty version of a scene than our eye sees. Dark tones become darker, falling into solid black, and light areas may burn out in a photograph even though our eye can preserve detail in the same scene.

We started our exploration by making a purposefully "bad" shot -- taking a person into tricky or unflattering light and trying a photograph there. We noticed where light falls on the human face, and it creates a shape (for better or worse). We then followed that up by trying to "repair" the light in that spot. We added a reflector to fill in shadow areas, or used fill flash to try to better light the subject.

Fill flash can be tough, and we struggled with it. That's not a problem: it's tough for photographers at every level. We again practiced methods of balancing ambient light and on-camera flash, and we looked at what happens when we're able to bounce light off a ceiling or wall. We also tried bouncing off a reflector or using a reflector as diffusion material.

We attempted to understand the qualities of light: hard light versus soft light, the directionality of light, the color of light, and then tried an experiment in seeing how we could "short" light a person's face. Our basic technique here was to put the subject in a position where they turned slightly to the right or left. We then looked at which cheek was "leading" (toward the camera) and experimented in giving that cheek more light or deemphasizing it by letting shadow fall on it. This clearly changed the shape of the face as read in the photograph.

We also looked a bit at how focal length effects the face: we compared the same framing of a face at medium and telephoto focal lengths and realizing that longer focal lengths appear to compress or flatten the features.

We also tried to put all these elements together for a casual portrait, trying to train our eyes to see the light, while still choosing a good framing, appropriate focal length and maintaining a relationship with our portrait subject.

In the end, however, our goal was to stop projecting our expectations of what we'd see and really see the light present. As well, this was a lead in to next week, when we will be using studio lighting and trying to really see and control light.

Our homework was to shoot one portrait of this type, using natural light or adding flash as needed.

How About No?

I find that people project their own ideas on me all the time. Perhaps I make that easy: they figure I want whatever it is that they want. Generally I don't.

Connecting A Sony To Studio Lighting

Studio lighting is generally triggered by a cable that has a "PC" connector on one end -- the end that connects to your camera -- and a guitar-plug connector on the other that connects to a monolight or the power pack for a studio lighting kit. At one time, that "PC" connector was fairly universal, provided on even entry-level SLR cameras.

In the era of digital cameras, the PC connector -- not anything to do with personal computers, just an older electrical connector used for decades in camera equipment -- has become a "pro" feature and is not usually available on entry-level DSLR cameras, and not even on some of the midline cameras.

You can compensate by putting a radio trigger on your camera's hotshoe, or triggering the studio lights by using your on-camera flash in a way that hits the lighting kits sensor.

It's best, however, to get an adaptor that will let you work directly with the PC cable. And it isn't expensive. For Sony DSLR's the way to go is the Seagull SC-5 Hot Shoe Flash Adapter to PC and Standard Hot Shoes for Sony Alpha / Minolta Maxxum Cameras. You slide it onto your flash hot shoe, and it has a PC connector on the side. Plug in the PC cable there and you can use studio strobes anywhere.

Words, Words, Words

Here are two links about the documentary process. Also something or other about me in there as well. (You can read it as a drinking game, if you like: every time I go on too long about a point, take a drink. When I say something overserious about the documentary process, take a drink.)

Prose On Park Avenue Purple Post

A long while back I was walking to a meeting on Park Avenue when I ended up behind a nice couple. The woman had purple hair, so out of reflex I snapped a photo with my iPhone. There wasn't much to it, just a snap.

Today, again on Park, I found myself behind the same couple. "No need to take a picture," I thought. "I've already got one."

That's when a woman walked toward us, also with purple hair.

So I whipped my phone up near eye level and took the shot.

Advanced Photography, Week One

Last night I taught the first session of Advanced Seriously Fun Photography.

We started by developing our goals for the class. I tailor the class to the people taking it, so we have some freedom with choosing topics and how we learn those. After some review of technical basics (I'll put that at the end of this post) we explored a range of possibilities using shutter speed. We worked at figuring out the correct exposure in our dimly lit classroom, and then realized that for a still life we could overcome that by using longer shutter speeds. Of course, below 1/60th of a second we found that handheld shots can soften or blur, so we started using a tripod. By using slower shutter speeds, we were able to shoot a still life even at f/16 or f/22.

Then we explored how much blur a pen falling off a desk would have at various slow shutter speeds. We then figured out how fast we could push the shutter speed to freeze the pen -- under the existing available light conditions. In our dark classroom, we found the limit on one of our cameras was an exposure of 1/500th of a second at f/5.6 and ISO 3200.

We then learned that this control over shutter speed was very helpful if we were going to try to balance on-camera flash with an exposure for the background. So we went through a process of determining a good manual exposure for a background, then adding flash to a shot to light our subject. After a bit, we were able to control both: we could make our ambient exposure one stop dark and adjust flash compensation, and that gave us good control over both our subject and the ambient background.

We later tried "dragging the flash" -- holding the exposure lock button in a dim situation and letting the camera use a slower shutter speed. This helped us to quickly get a balance between the background exposure and our subject.

Next we explored the amount of blurring that shutter speeds allow. We started with exploring someone walking as we tried 1/30th of a second and 1/15th of a second. We then added flash to this and discovered how a trail was created, and then how we could control where the trail was by using second-curtain or rear-curtain sync.

Then we spun umbrellas at varying speeds and explored slower shutter speeds in relation to the amount of blur. We also explored using fill flash on a person to fill-in areas where ambient lighting was leaving heavy shadows.

After clarifying the techniques available to us changing shutter speed, and a few basics on adding flash, as a last technical experiment, we lined everyone up in the hallway and explored how we could use aperture to control depth-of-field, taking a range of shots from f/5.6 to f/22.

The homework for this week is to explore that ambient / flash balance. You can hear Ted talking about this subject here: Ted explaining matching flash and ambient lighting.

Also, try out your own version of our Depth-of-Field experiment.

The photographers to research this week are Mary Ellen Mark and Elliott Erwitt.


We learned that to control exposure, we need to work with three related elements: Aperture, Shutter Speed, and Sensitivity.

The f/stops to memorize are f/1.4, f/2, f/2.8, f/4, f/5.6, f/8, f/11, f/16, f/22. If you forget these, make two columns, and at the top of the left one write 1.4 and at the top of the right one write 2.0. Now double each number as you go down the column (rounding off when needed). Changing one stop lets in twice as much light (or half as much, depending on which direction you go. f/2 lets in a lot of light, f/22 lets in very little light. So if you took a picture using f/8 and it seemed a little too dark, you would switch to f/5.6. If you took a picture using f/8 and it seemed a little too bright, you'd switch to f/11.

Shutter Speed:
The common shutter speeds are:

1/1000th of a second
1 second.

-- As a rule of thumb, if you are moving and you're subject is moving, you'll want to be shooting at 1/1000th of a second to get a sharp picture.

-- If you are still but the subject is moving along, it would be good to be at 1/250th or faster.

-- If you and the subject are both relatively still, you can probably handhold the camera as slow as 1/60th, but slower than that and you'll get a soft picture because of camera shake caused by pressing the shutter.

-- At speeds that are slower, you'll need a tripod to steady the camera, and probably want to trigger it using the self-timer or a release.

-- Many decent cameras have higher shutter speeds, and these are very useful for action or sports.

Notice that the relationship of these shutter speed settings is also doubling (or halving) the amount of light that hits your sensor.

This is the ISO "speed" of a digital sensor or of film. ISO 100, 200, 400, 800, 1600 and 3200 are available on many cameras (but not all), and you should take some test shots with yours to find out if the higher ISO settings are usable or not. Figure out the fastest ISO speed you find produces acceptable shots on your camera -- you'll need to switch to it sooner or later. Notice that each ISO speed is twice as sensitive (or half as sensitive) as the next.

Then we decided to start applying our general knowledge about the relationship between apertures and depth of field. While we start to get the idea when we say "f/2 -- shallow depth of field and f/22 - deep depth of field" actually trying this out in with some real world shots is always a good experiment.

So we set up an experiment that can be repeated at home: set your camera on a table or a tripod, and in front of it arrange people or objects in a receding line. Put the first person or thing just 3 feet away from the lens, and have the furthest be at least 12 feet away. Now set the widest aperture you can -- I use a lens that goes to f/1.4 for this -- and focus on the closest person or object. You'll probably find that the people / objects behind that are out of focus. Now run through the whole series of aperture settings you have available (you'll probably want to be in "aperture priority mode" so that the camera sets the corresponding shutter speed for an acceptable exposure. Or you can set that yourself). Try this and compare each shot -- more and more will be in focus until you should be able to get everyone in focus.

Now, keep in mind there's one other factor here -- the focal length you shoot with. Usually the effect of getting a main subject in focus and the background out of focus is much easier to achieve if you use a lens of at least 50mm or set as zoom to 50mm focal length or a more telephoto setting.

Many photographers think that "telephoto lenses have shallow depth of field and wide angle lenses have deep depth of field" -- it turns out that isn't exactly true, but for pragmatic purposes it isn't a bad way to think. If the goal is a sharp subject and a blurry background -- grab a 90mm or set your zoom lens about there.

(For a discussion on why the wide focal lens = deep depth of field idea isn't precisely true, read Do wide-angle lenses give you greater depth of field than long lenses?.)

Another thing that comes up at this point: some lenses allow your camera to reach to f/1.4 or f/2 or f/2.8, but many times the "kit lens" zoom that comes with a DSLR or the zoom lens built into a compact camera will not go to that wide-open an aperture. And to further add to the confusion: many common lenses that go from 18mm to 55mm (or 70mm) let you go to f/3.5 when using the widest focal length (18mm) but only to f/5.6 when you are using the long end of the lens (55mm or 70mm). That's just how those lenses are built.

Now, once we know a technique to control depth of field -- go towards f/2 to get a sharp person, blurry background or toward f/22 to get subject and background both focuses -- we want to think about why we would do it. Well, it's that kind of control that lets us emphasize or deemphasize what a viewer sees in a photograph, so we want to master it so we can control our images. Need to photograph a person against a cluttered, distracting background? Use selective focus. Need to show that a person has kids but keep the emphasis on the person? Use selective focus to make the kids visible but de-emphasized.

So, from a technical standpoint, as we approach any photo situation we'll want to decide on an ISO setting, a shutter speed and an aperture. The three are interrelated and all use a doubling / halving system so it is easy to calculate how to change them when needed.
