Penguins and lights

Nikon D7000, 10.5mm, 8 sec., f/8, ISO 100, adjusted

Last Sunday the family did the annual lights tour, driving around the city after dark and looking at some of the more elaborate displays. One of our traditional stops is Pauly’s Penguin Playground, a wonderful riot of inflatable, mostly penguin-related decorations. For some time now I’ve wanted good pictures of this spot, but in the past I haven’t brought the right equipment.

I’ve been reluctant to drag a tripod into the middle of everyone’s holiday fun, but without some kind of brace it wasn’t really possible to leave the shutter open long enough to get a proper exposure. The compromise: the monopod with its three-pronged base extended. It was still a bit more jiggly than I wanted, but it helped a little to use a remote rather than the on-camera switch.

They didn’t all come out perfect, but I was pleased with some of the results.

After that we mostly stayed in the car and drove around, which of course made it hard to shoot the long exposures required by low light conditions. However, I thought I’d have a little fun at one spot. The result can’t accurately be called a realistic depiction of the scene, but it’s kinda pretty.

O Christmas Tree

Nikon D7000, 18mm (18-55), 20 sec., f/6.3, ISO 100, adjusted

Faithful fans of the blog may recall that a couple of years ago I posted a fancy time exposure of our Christmas tree. This year we changed the decorating scheme a bit. But as before, a low ISO kept the colors true and long shutter speeds brought the lights out (harder this time because the new bulbs are smaller).

I shot the lead-off picture shortly after I put the tree up and got the lights on it. And then overnight it snowed, giving me another good photo op in the wee hours of the morning.

Light and fog

Nikon D7000, 200mm (28-200), 3 sec., f/8, ISO 400
Photographers are supposed to have a “thing,” a particular kind of subject or style to specialize in. I’m having too much fun with the art to settle down in any one area, but if I did have a “thing” it would probably be mist. I love how it feels to be out in it, and I love how it plays with light when it’s photographed.

Here’s a playful little piece I took last week. The neighbors’ Christmas lights looked so nice in the fog, I had to get a picture. Naturally this called for a slow exposure to get the light right.

Unfortunately, my good tripod was at work. So I used my travel tripod to brace the camera. Portable though it may be, it doesn’t hold the camera firm enough to avoid the small camera shake caused by pressing the shutter button. You can see the small dip the camera took, which shows up as little hooks at the bottom of the bright lights. Once the button pressure was off, the rest of the time the camera stayed still. Thus the dimmer parts of the picture (which took longer to expose) show no blur at all.

Happy holidays

Nikon D7000, Lensbaby Scout with single glass optic, 3 sec., sunburst aperture, cropped

Here’s something fun to help kick off the holiday season. This photo was done entirely with the camera. Other than a small crop, I didn’t do a thing to it in Photoshop.

What you’re looking at here is a six-inch-tall creche (propped up on a support) with our Christmas tree in the background.

I achieved the effect by using a Lensbaby Scout with a single glass lens and a sunburst aperture. Rather than a standard, circular aperture, the disk for this shot was a shape. You can see the edges reproduced in some of the less fuzzy sunbursts in the background. The in-focus foreground is unaffected; the creative aperture works like a plain old circular hole. But bright light sources in the out-of-focus background take on the shape of the aperture. It’s tricky to get it to work just right, but when it does, it creates some interesting images.

The single glass and narrow depth of field gave the foreground a bit of blur that added to the appeal.

The Patriot

Nikon D7000, 72mm (28-200), 1/640, f/6.3, ISO 200, cropped

First rule of late season visits to Worlds of Fun: leave well before Haunt gets underway. None of the photos I tried to take after dark worked out. However, I did have some fun earlier in the day.

The first ride my group went on was The Patriot, one of the park’s many roller coasters. I managed to find a spot that gave me a couple of good angles. The shot above proved to be a good example of how to imply movement in a “frozen motion” shot via body angles. You can tell that the coaster is moving with some speed because otherwise the seats couldn’t be at that angle.

The other way to convey motion is through blur. I propped the camera on a fence so I could slow the shutter down enough to blur the moving coaster here:

Nikon D3000, 10.5mm, 1/10, f/22, ISO 100, adjusted

Then I decided to have a little fun with it. I shot a series of pictures with the coaster at several spots along the track. Then I used layers in Photoshop to combine them all into one picture that shows the whole sequence.

Head

Here’s a treat: a creepy photo of a shrunken head. This objet d’art can be found at the Sternberg Museum in Hays, Kansas. The Blogger software distorts the colors a bit, but you can still see nice detail.

Happy Halloween!

Light painting

Nikon D7000, 48mm (18-55), 5 sec., f/5.3, ISO 100

Last week we took a look at photos of moving light sources shot at slow shutter speeds. Today’s example is traditional “light painting,” using a light and a long exposure to draw something in the darkness.

This is impromptu stuff, shot with the flashlight feature on my iPhone. If this had been anything besides an experiment, I probably would have at least changed the backdrop to a black muslin to reduce the chances that it would show up in the shot (as it does a little here). I should also have removed the UV filter from the lens, as it’s likely to be the source of the faint phantom lines in the shot.

And if I was really getting fancy, I could have thrown in some rear curtain flash so that I would be visible in the shot. Or at least practiced a bit so I could legibly write the word “hello” (and do it backward so it would read correctly in the photo).

Picasso was much better at this.

Awika

Nikon D7000, 45mm (18-55), 3 sec., f/5.3, ISO 800, cropped

For our fun class session last week, we killed the lights, slowed down the shutter and photographed some moving light sources.

Our first subject was Awika, relative of Cosmojetz. I neglected to shoot video with the lights on, but the folks who created it have a good, quick clip. With the lights off, the only visible part of the scene were the sparks shooting out the back.

The first attempt (above) was a little over-exposed. To be sure, it was still a cool effect. The winding key and Awika’s feet are faintly visible. But I was curious to see what we’d get if we played with the exposure a little. First I dropped the ISO:

Nikon D7000, 45mm (18-55), 3 sec., f/5.3, ISO 100, cropped
And then I closed the aperture down a bit:

Nikon D7000, 45mm (18-55), 3 sec., f/11, ISO 100, cropped
Unfortunately, for that test I put the subject on the table upside down, so its body hid most of the sparks. One more try:

Nikon D7000, 45mm (18-55), 3 sec., f/11, ISO 100, cropped
Now the only visible parts of the subject are the narrow light trails made by the sparks. They look like fine hairs or dandelion fluff. Sometimes it’s nice to just play around and see what you get.

Waterfall

Nikon D7000, 44mm (18-55), 3 sec., f/29, ISO 100, on-camera filter, adjusted and cropped
Yesterday was the final in-class session of my fall Photography course. As usual, the last non-online meet was optional, and as nobody who showed up needed to get caught up on anything, we spent the time having some fun.

The main activity was a set of light painting experiments I’ll post next week. But after class I was still in a picture-taking mood so I decided to try a new filter I bought awhile back.

The main idea behind neutral density filters (other than protection for expensive lenses) is to reduce the amount of light getting into the camera without affecting the color or image quality. The new toy in this case was a Hoya 52mm 3-400 variable density filter.

Variable density filters can be adjusted to let in more or less light. The minimum setting for this one lets in 1/3 of the light that would otherwise get through the lens, the approximate equivalent of 1.5 stops. At the opposite end of the scale the filter screens down to 1/400 of the light, around nine stops.

The photo at the top of this post shows the filter near maximum strength. The ISO is down as far as it would go and the aperture closed up as tight as it would go. The result is not much light getting through and not much sensitivity to record what does get through. That’s how I got away with a three second exposure, which otherwise in bright sunlight would have over-exposed the shot so badly that I would have gotten nothing but an empty white frame.

At this speed the water (the only moving subject in the shot) turns into a hazy blur. Compare the long exposure to something closer to normal speeds:

Nikon D7000, 44mm (18-55), 1/125, f/5.6, ISO 100, on-camera filter, adjusted
Turning the filter down to its minimum allowed me to speed up the shutter and freeze the flowing water. Though the result is a great deal more “realistic” (i.e. more like what you’d perceive if you were actually looking at the scene), it’s arguably not as interesting to look at. The composition is  more chaotic, not as smooth as the longer exposure that records the general flow rather than individual drops.

Cosmojetz

Nikon D7000, 80mm (35-80), 1/125, f/5.6, ISO 800

This semester I’m going to blog a few of the exercises we do in my photography class. I want students who miss class to be able to see what we did. And for those of you who aren’t in the class, these are good examples of some photography basics (even if they aren’t the most spectacularly fascinating photos ever taken).

The topic for this lesson is shutter speed. Our model is a small wind-up device called Cosmojetz, the creation of artist Chico Bicalho.

I took the shot above holding the camera in my hands and using a middle-of-the-road shutter speed.

Nikon D7000, 80mm (35-80), 1/4, f/32, ISO 800

Next I slowed the shutter down a bit to demonstrate camera shake. This is the shot you almost never want, with everything a big blurry mess. As a photographer, you need to figure out how steady your hands are. I can’t shoot anything much below 1/30 (depending on the circumstances) before the blur starts to ruin my pictures. However, if you don’t have four decades of caffeine behind you, your hands may be more stable than mine.

Note that the one thing that doesn’t move in this shot is the dust on the lens, because when the camera shakes the dust moves right along with it, staying stationary in relation to the image recording chip. You won’t see the dust in any of the rest of the shots because when I noticed it I remembered to do my job as a photographer and wipe the lens with a lens cloth.


Next we locked the camera down on a tripod to completely eliminate camera shake. And we set the subject in motion. Here’s a video of what Cosmojetz looks like when it bounces around:


We started with another middle-of-the-road shutter speed:

Nikon D7000, 42mm (35-80), 1/125, f/4.5, ISO 800

As anyone who has ever tried to take a picture of a three year old can attest, rapidly moving objects can be tricky to photograph. Though 1/125th of a second seems like no time at all to us, a moving object can travel quite a bit even in such a small fraction of an instant. Thus the blurring that clearly indicates the subject is on the go.

Nikon D7000, 42mm (35-80), 1/250, f/4.2, ISO 800

Increasing the shutter speed still further reduces the blur to manageable levels, though you can still see a bit here and there. In shutter priority mode, the camera has been automatically adjusting the aperture for us to make sure we get a good exposure. But now we’ve reached the limits of the lens; the aperture won’t open any wider, and we’re starting to sacrifice image quality.

Of course at this point we can fix the slight under-exposure in Photoshop, like this:

Nikon D7000, 42mm (35-80), 1/250, f/4.2, ISO 800, adjusted

But if we want to freeze the motion entirely, we’ll need to speed the shutter up still farther. And that will mean increasing the ISO (making the camera’s image sensing chip more sensitive to light) to get a good exposure.

In the shot below, motion blur has been completely eliminated. The only way you can tell that the subject is moving is that otherwise it would have to be hovering in mid-air.

Nikon D7000, 42mm (35-80), 1/1600, f/4.2, ISO 6400

The lesson ends at the opposite end of the scale. Slowing back down to a quarter second (the speed that gave me such terrible camera shake earlier), transforms the rapidly-moving subject into a ghost, barely visible in the upper part of the photo.

Wyandotte County Courthouse

Nikon D3000, 18mm (18-55), 1/250, f/8, ISO 100, cropped
Earlier this week I shot some pictures of the Wyandotte County Courthouse. This is part of a project I’m working on for the Kansas Association for Justice.

I started out with some standard angles such as the one above. But I swiftly found myself captivated by the small details. For example, I liked the oil derricks in this bit of ornamentation:

Nikon D7000, 200mm (28-200), 1/2000, f/5.6, ISO 280, edited
 As you can see from the wide shot, the sky was completely cloudless, and as a result the shadows were fairly harsh. Photoshop helped even out the highs and lows. It also removed some of the perspective distortion that came from shooting from a low angle.

Nikon D7000, 200mm (28-200), 1/1000, f/5.6, ISO 400

I was also quite fond of the details and colors on the fixtures on the front stairs (also visible in the wider shot).

Stars

Nikon D7000, 10.5mm, 30 sec., f/2.8, ISO 800

The whole time we were in New Mexico, I kept hoping for the chance to photograph the night sky. We were staying in Dixon, a small town far enough from city lights to allow me to get a good shot of some stars.

So naturally it was monsoon season. Every single day the sky clouded up late in the afternoon and stayed overcast until well after I’d gone to bed.

But on our second-to-last night there, I finally got some luck. The skies cleared almost entirely (you can still see some clouds toward the bottom of the shot) and I finally got the shot I was after.

I set up a tripod in the courtyard of the mission where we were staying and took the picture with a wide angle lens. So you can see roofs, trees, a pole and some power lines. The light in the window in the lower left-hand side is from my wife’s phone. A 30 second exposure will pick up just about any available light.

Mesa Verde

Nikon D3000, 10.5mm, 1/250, f/6.3, ISO 100
While in New Mexico I took a side trip up to Colorado. I have fond memories of a childhood visit to Mesa Verde, so I thought I’d drive up for the day. If nothing else, I figured I’d find some good photo opportunities.

Which I did. The best part of the trip was the hike to Petroglyph Point. Just a little way up the trail the crowd thinned out considerably, and by the time I reached the carvings I was virtually alone. What fun it was to use one of the world’s newest communication methods to record one of the oldest.

The trail started and ended at the Spruce Tree House cliff dwellings. The crowd was much thicker there, but from the right angles it was possible to get shots without too many tourists in them.

I even managed to shoot a short panorama.

VLA

Nikon D3000, 10.5mm, 1/400, f/10, ISO 100, cropped and adjusted

Earlier this month my wife and I took a trip to New Mexico. Amy was there to work, which left me with some time on my hands. Figuring I might not make it back to this part of the country again anytime soon, I picked a couple of destinations I’d been meaning to visit.

The first was the Very Large Array radio observatory, 50 miles west of Soccoro, New Mexico. I’ve loved astronomy ever since I was a kid, and though I don’t have the math skills to pursue it seriously, I still like to visit museums, observatories and the like. If you’re into this sort of thing, the VLA is definitely worth a trip. It’s refreshing to see a government operation that’s actually open and accessible to the public. The tour was excellent; the guide even sounded like Carl Sagan. Just don’t trust Apple Maps to tell you where the turn is.

I lucked out in the timing department. The dishes were in their A configuration, which meant that they were as close together as they got. If they had been in the D configuration, they would have been more than 20 miles apart and not such an awesome photo op.

Even so, photographing them was a challenge. To convey a sense of the scene, the photo had to do two things: show all the dishes (or at least as many of them as possible) and convey just how big they were. Accomplishing one of the two tasks was easy. I used a wide angle lens to take the picture at the top of this post. It caught the whole array. But the scale is hard to read. Without something familiar for a scale reference, these could be no bigger than the dish currently serving as a weed arbor in my neighbor’s yard.

Getting in closer and adding some people to the composition helps establish the scale. But now you can’t see the array.

Of course I could always piece a pan shot together. This does the job if you can view it at full resolution. But shrunk down to a web-friendly size, it isn’t much better than the first picture.

Here’s about as close as I could come to a good compromise:

Atomic Annie

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.

Cemetery

Nikon D3000, 24mm (18-55), 1/200, f/7.1, ISO 100, edited

One of the pans I posted three weeks ago was shot in a cemetery not far from the Cathedral of the Plains. It was a tricky place to shoot from a storytelling standpoint, because different angles told much different stories.

Some of the grave markers were a little different from the stones that are common in this part of the world. They’re made from metal pipes, some fairly plain and some ornately decorated. A line of these older markers toward the back edge of the ground made it easy to compose a shot simplified down to the subjects, the prairie and the sky.

The photo below is a lot more inclusive representation, more like what you’d actually see if you were there. On the other hand, the composition is cluttered. The different kinds of headstones look chaotic, and the power lines in the background don’t exactly help. Overall this is arguably more accurate, but it’s much less peaceful.

Plaza bunnies

Nikon D7000, 18mm (18-55), 1/200, f/7.1, ISO 200

For years we’ve been meaning to get down to the Plaza during the Easter season and photograph the giant rabbits. This year we finally did it.

This shot was extremely popular on Facebook. It got more likes than anything else I’ve ever posted.

Nikon D7000, 18mm (18-55), 1/200, f/7.1, ISO 200, adjusted and cropped

Largely because of the shade, the photo needed some adjusting in Camera Raw. I switched the white balance to “auto,” changed the levels on the shadows and whites, and moved the clarity up a bit. I also took advantage of the lens distortion correction feature, which had built-in settings for the Nikon lens I used and fixed some of the bloating caused by the low focal length. This is what the original looked like:

My only big disappointment was the bunnies’ eyes. They used to be red light bulbs that created a glowing devil bunny effect at night.

Photoshop to the rescue!

Cathedral of the Plains

Combination of several shots

The trip to Hays and thereabouts took us to the Cathedral of the Plains. I neglected to bring a tripod, so I didn’t think I’d get suitably awesome shots inside. But I had some fun shooting outside.

The example above is actually stitched together from a set of shots, the first time I ever tried this Photoshop feature on anything other than a straight left-to-right pan. It produced some interesting results (note the odd bend to the tower on the left).

I also took some less elaborate photos. The framing on this shot was fun, with the curve of the rose window forming a halo around the statue’s head.

Kansas pans




I went a little pan-happy during a recent trip to Hays. Kansas landscapes – from the Flint Hills to open pastures – invite extra wide compositions. I managed to get some good results even without a tripod. As usual with pans, you’ll get a better sense of the full effect from the larger view you get by clicking.

The first one is unusual. Most pans are created by panning (so it isn’t just a clever name) from a single point, typically the head of a tripod. But for this image I shot several photos while walking past a series of headstones in a graveyard. The result required considerable adjustment (Catherine Mary’s stone is still a bit more distorted than I’d like). But it’s still awesome how a set of five crudely carved rocks can tell such a poignant tale of a family’s tragic losses.


Here’s something more traditional (and less depressing). This pan covers 180 degrees along the side of the road near a large wind farm. I liked the contrast between the solitary, traditional windmill and the acres of giant wind chargers. This one’s more fun at full resolution than it is on the Blogger screen (though you can get a slightly better look at it by clicking on the image).


This is Fort Riley viewed from atop Atomic Annie Hill. The view extends beyond 180 degrees. Shooting down into the valley also caused the series to arc rather than line up straight, which cost a lot of picture at the top and bottom. Thus the narrow image.

Bedtime for Howie

iPad

One thing having a black cat has taught me is that black cats can be hard to photograph. Unless you catch them from the right angle in the right light (as in last week’s example), they can easily turn into silhouettes with eyes. That’s sorta happening in this picture. His right ear is missing from the shot, blending almost entirely into his head. Fortunately he was reclining on a pillow, so the shadow creates an ear that would otherwise be invisible.

I blogged this photo at least in part as a reminder that photography doesn’t have to be all about expensive cameras and fancy lenses. Nor does it have to be about portfolio-worthy masterpieces. The technical quality here isn’t great. But I love the moment it records.
