Atomic Annie

Nikon D7000, 35mm (35-80), 1/250, f/8, ISO 100, adjusted

Here’s another closer look at one of the stops on last month’s trip to Hays. Atop a hill across the interstate from Ft. Riley sits Atomic Annie, a large artillery piece designed to fire nuclear shells.

A mid-distance shot such as the one above provide a good sense of the subject and its surroundings. But it also doesn’t hurt to get in closer and capture peeling paint, scratched-on graffiti, and an interesting combination of diagonal lines.

State Fair – The Scrambler

Nikon D3000, 10.5mm, 0.4 sec, f/18, ISO 100

I didn’t catch this ride’s actual name. But I’ve seen this sort of thing called a Scrambler elsewhere, so we’ll go with that.

I shot this set under some unusual lighting conditions. The day was getting on toward dusk and the sky was overcast. The result was outdoor light that looked normal but wasn’t intensely bright. And that allowed me some leeway with my settings. I was also able to brace the camera on a rail, which meant I could slow the shutter down farther than I could have with a strictly hand-held shot.

Thus I was able to capture some interesting light trails while freezing the objects and people around the ride. On the first shot (above), the orange trails and blurred car looked sorta like a tornado.

The ride moved around in patterns that were difficult to predict. So some of the shots were mostly blur while others featured clearer images of the riders.

Though I framed most of the set horizontally, I also managed to capture a few good ones with the camera turned 90 degrees.

Omaha Zoo – Miscellany

Nikon D3000, 10.5mm, 1/640, f/13, ISO 1600

This last Omaha-centered blog entry picks up a handful of miscellaneous photos I took during our visit. Though I had my wide angle lens with me, I ended up not using it for all that much. Every once in awhile I got a good result from it, however. I was pleased by the strangely-bending lines of the dome atop the desert building.

I honestly thought I’d walk away with pretty much nothing from the nocturnal exhibit, but a shot or two sorta worked. For this picture of an alligator I cranked the ISO way up and braced the camera on a railing to avoid as much shake as possible. Still, you can see some camera shake in the shot. Look at the small points of light such as the reflection in the gator’s eye, which should be single points but turn into tell-tale crescents because of camera motion.

I should also note that the gator shot was seriously level-adjusted in Photoshop. Straight out of the camera, the frame was mostly black.

I hoped for some good wide angle shots while we were up on the sky tram (the cables for which you can see in shadow running through the middle of the picture). However, the 10.5mm lens kept getting my feet or another part of the tram in the shot, so I had to settle for sorta-wide-angle 28mm pictures from my other lens.

At least this photo demonstrates the value of getting up above your subject for a “lay of the land” picture.

I had to optically zoom in as far as I could and then “digitally zoom” by cropping in order to capture these dour residents.

A wider group shot was less technically demanding.

Some of the most dramatic residents of the rainforest building were giant (like serious shark sized) carp with beautiful gold edges on their scales. The viewing angle and water surface reflections made any kind of documentary shot impossible, and I almost gave up on photographing them at all. But once I gave up the notion of trying to get a clear shot and just went with the beautiful, abstract forms of line, shape and color, I ended up with some pleasing pictures.

Silo demolition

Back in my film days, I spent a fair amount of time photographing buildings in the process of being demolished. Here’s another example.

Notice the difference between the two shots. The subject is the same; the only change is the camera angle. The shot above was taken from a nearby overpass, and the shot below was taken from ground level. Note how the two images look and feel different.

SAC Museum

Actually, this is the Strategic Air and Space Museum. But I’m used to this branch of the Air Force being called Strategic Air Command, so it feels better to me as SAC.

These shots of the SR-71 Blackbird in the main entry hall show off different lenses and different framing options. The first shot (above) is a fairly standard composition with one of my everyday use lenses. It’s at the lower end of its focal length range (18mm), so I’m getting a little distortion. But because the airplane itself is made of long, curving angles, the distortion doesn’t mess up the shot.

Now I’ve switched to my other camera, where I’ve got my 10mm lens mounted. On the minus side, this isn’t as dramatic a shot of the Blackbird. On the plus side, the wider angle provides a better sense of the space in the hall. I also like the frozen motion on the kid in the right-hand side of the shot.

Then by tilting up a bit I get this result. The top of this picture is actually the ceiling behind me, making for some strange perspective. I like the geometry of this image, the solid, iron-shaped roof floating in a web of thin lines.

Cave bear part two

Nikon D7000, 30mm (18-55mm), f7.1, 1/40, ISO 6400

We aren’t quite done with the bear skeleton yet. The last post was getting a little long, but the subject has a little more to teach us.

I took the photo above with the same camera but from a different angle and a slightly different focal length. This shot doesn’t provide as good a sense of the bear’s surroundings. But the Aaaaaagh! factor is much higher. Those teeth! Those claws! If this thing hadn’t been dead for millennia, I’d be in serious trouble right about now.

You can use this shot to apply what you learned last week. How could you edit this picture to make the bear stand out more? If you have a copy of Photoshop (or other image editing software), feel free to download the image and play around with it.

Now here’s the same subject shot with a different camera and lens:

The fisheye allows me to get the whole skeleton in while at the same time preserving the sense of menace. This would have been a tougher edit, however.

Before we leave the Field Museum, let’s look at one more subject: ISO. Museums tend to be good places to practice your exposure control. Subjects tend not to move around a lot, so you don’t have to fret about losing your shot. Still objects also eliminate a lot of shutter speed worries (if it isn’t moving, you don’t have to care much about subject motion blur). You will probably also encounter many different lighting conditions, which should keep you mindful of your shutter and aperture settings.

The big challenge is typically that museums tend to use lighting that’s pleasing to the eye but too dim for photography. The easiest way to compensate for the lower light (other than using a tripod, which most museums don’t allow) is to bump up your ISO, making your camera’s imaging chip more sensitive to available light. However, there’s a trade-off involved.

See how grainy the picture looks? That’s the result of turning up the ISO to 6400. The problem doesn’t show up in the larger picture. But when we “blow up” to the actual pixels, you can see where the camera’s chip is starting to make mistakes. That’s the ISO trade-off. Higher settings allow you to capture images in much lower light, but the quality of the picture can suffer as a result.
