Fun Times On A Houseboat

July 20th, 2009

I shot the houseboat below for a client recently and a couple of images stood out during the shoot that are interesting in a photographic sense.

The first is this fun exterior with the Aurora bridge. Nothing technically challenging with this, but I like the way the bridge overhead and reflected below frame the house nicely. Shot with a 24-70 lens at 24mm with a circular polarizer to help out the blue sky.

Photography is "Problem Solving 101"

The second shot artistically is less interesting but there is more problem solving going on than first meets the eye.

First: I’m on a houseboat. Houseboats float and move with the waves. Which means I need to keep a fairly high shutter speed. Not too much of a problem since the scene if already very bright.

Second: I’m trying to shoot a “deck” which in reality is a “dock”. It’s floating too and much less stable than the house. See above.

Third: The contrast, or dynamic range, between the shadow area and the full sun area is too large for my camera to capture in one exposure.

Solutions

There are several ways this could be approached.

1) Use several images with different exposures and blend them together in Photoshop later. That would work fine but takes too long for this particular job. The movement of the dock and boats between frames might make this a bit tricky.

2) Use several images with different exposures and blend them automatically using an HDR or Enfusion program. That would normally be a good option, but again the potential movement of dock and boats would cause ghosting or copies of elements. Shutter speeds could increase too much trying to get a proper exposure for the shadow are and motion blur could occur.

3) Use a graduated neutral density filter and place it over the full-sun portion of the frame to bring the exposure for the two areas closer together. This works best when the shadow line is nice and straight and the shadow line in this picture isn’t straight. Also I don’t have a graduated ND filter in my kit right now.

4) Wait. I actually did wait to get the shot, but I couldn’t wait as long as I needed. Waiting is a good option and would have produced a nice result when the sun was setting or behind the nearby hill, but no time for that.

5) Use fill-flash. Since I bring my hot-shoe flashes to real estate shoots I had them available. For this sunny day it took two flashes on full power to bring the shadow area up to a relatively decent level so it still looks like shadow, but doesn’t look like a large black area.

Manage the light

Most photography is about managing the differences between the shadow and highlight areas of a scene to bring them closer together so the camera can capture the scene as our eyes see it. While there are a multitude of ways to accomplish that, it always comes down to what works best for the given situation and the effect you are trying to produce.

Give a Four Year Old a Camera….

July 17th, 2007

My four year old son likes to take pictures.

He was pretty adept at using our Canon PowerShot S410 before it died. He now likes to use our Canon Rebel XT. This is our “family” camera that we use when taking most pictures of the kids around the house. It’s small, and with a 50mm lens attached, very light. Not a pocket camera, but it also doesn’t suffer the lag that most point-and-shoot models have. When the camera is on full-auto mode it exposes well under most circumstances and is easy to use by the non-camera people in the household.
Every so often my son will pull off a nice shot like the one below.

It just shows you how good digital cameras have gotten. With a quick focus and proper exposure they can produce very nice results (and not a bad composition either). Of course having the right lighting always helps.
That being said digital cameras can also produce not-so-good results. When the lighting isn’t right for the exposure setting on the camera, the results can be less than appealing. The trick is in knowing how your camera handles the difficult situations and what to do about them.
Backlighting is always a tough exposure for a camera. Most cameras are going to be left in their default metering mode which usually takes the entire scene into account when trying to determine the proper exposure. With a bright background the camera is going to try to find an exposure that will show the background properly, leaving your foreground subject very dark.
Knowing this you can do one of two things. 1) switch the camera to spot-metering if possible. This will tell the camera to judge proper exposure off of the center of the scene, most likely the subject you want to be exposed properly, and to not worry about the background. 2) Add some fill-flash. If your camera has an on camera flash, make sure it is set to on and take the picture. The camera will use the flash to bring up the light level on the foreground subject to approximately the level of the brighter background.

Most point-and-shoots will not use the flash for a backlit scene, so it is important to know how to set your cameras flash to On rather than Auto. The picture above is a perfect example of a backlit scene. The kids are entirely within the shadow but the fence behind is in direct sunlight. Without the fill-flash the shadowed area would have been very dark.
