Fireworks 2018

Nikon 810, 28mm (28-105), 2 sec., f/4.5, ISO 100

This year I thought I’d try something new for Fourth of July photos. A Petapixel article described a technique that produced puffy, flower-like images. My results differed, but I’m nonetheless pleased with what I got.

The trick was to set the shutter for long exposure (I went with a second or two), start with the lens completely out of focus and then snap to clear focus while the shutter was still open. The result is an image that’s partially in focus and partially out. It ended up creating an illusion of depth of field, which altered the perceived size of the subject (kinda like the tilt shift technique).

Our eyes work in ways quite similar to our camera lenses. So we're used to a more or less infinite depth of field for subjects at a distance but a narrower field for things that are close to our faces. That's why the part-in-part-out focus of the fireworks photo creates the illusion that it's a smaller object closer up.

I also brought the wrong tripod (going with the heavy one for stability but forgetting that it can be kind of a pain to point up at any angle greater than 60 degrees or so). So several of my sky burst photos were hand held, producing another interesting effect even when I wasn’t changing the focus mid-shot.

Fireworks 2016

Nikon D7000, 28mm (28-200), 1/60, f/4.5, ISO 6400

Once again our Independence Day celebration was full of fireworks and photography. For the most part I stuck with standard techniques: long exposures for light painting and short exposures for sparky blasts.

However, I tried one trick:

Nikon D3000, 48mm (18-55), 5 sec., f/11, ISO 200, front curtain flash

This shot combines a long exposure with an off-camera flash. The flash fired as the shutter opened, when our friend Brandon was still lighting the fireworks. He was illuminated strongly only during the brief fraction of a second when the flash went off. As he swiftly got out of the way, he doesn't appear in the long exposure part of the shot along with the stationary tub or the light trails from the sparks.

Of course we had our usual fun finding creative ways to blow things up.

That's a Pringles can meeting a fiery end.

 And that's a tennis ball stuffed with ground-up sparklers.

And though smoke bombs are typically better during daylight, lighting a bunch of them at once produced a nice effect.

Roman Candle HDR

Nikon D7000, 18mm (18-55), 5 sec., f/22, ISO 400, cropped, three shots combined via HDR

High Dynamic Range editing is designed to bring out the best of all parts of a picture, blending the properly exposed sections of multiple shots into one image. But every once in awhile the resulting image is actually greater than the sum of its parts.

The picture above was created by using Photoshop’s HDR option to combine the three photos below.

Nikon D7000, 18mm (18-55), 5 sec., f/22, ISO 400


I shot these by mounting the camera on a tripod and tilting up to photograph the tree above me while a friend shot a Roman candle amid the branches. I honestly had no idea what we’d get, so I was pleasantly surprised by the result.

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.

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.

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.

Exile in the rain

D3000, 10.5mm, 0.3 sec, f/8, ISO 200, adjusted

Around a month ago I got a rare confluence of events: a rainy night and the free time to go out in it and shoot some pictures. I promised Amy I’d photograph the neon at Exile Tattoos some damp evening, so this seemed like the perfect time.

Naturally I brought a tripod along so I could work in the dim light. I started with the 10.5mm lens, taking a few shots in the lobby (below) before moving outside for the pictures I came to get (above).

D3000, 10.5mm, 0.5 sec, f/8, ISO 200

The outdoor photos I took with the 18-55mm zoom didn’t turn out as well. While I remembered to bring the camera’s raincoat, I neglected to bring one for myself. Thus I ended up drenched before I got anything I was happy with.

On the other hand, it wasn’t raining indoors. So while I had the camera on the tripod, I decided to play around with a special effects trick: zooming with the shutter open. The technique produces a strange, streaky effect that draws attention to the center of the shot. I’d tried the trick a few times in the past, but this is the first time I got genuinely interesting results:

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.

Nikon D3000, 10.5mm, 1/8, f/22, ISO 400

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.

The K at night

Nikon D3000, 10.5mm, 1/25, f/2.8, ISO 800

No sooner do I get the State Fair series going than I have to interrupt it for “breaking news.” With the end of baseball season fast upon us, I took advantage of our final Friday night at the ballpark to shoot some pictures.

I tried a few traditional shots of the game, but the longest lens I brought with me maxed at 200mm. From the back of the stands, it wasn’t exactly producing Sports Illustrated cover shots. Likewise my attempts at street photos of the crowd weren’t working. Perhaps I was in a moody mood, but I wasn’t feeling the people thing.

On the other hand, I found myself captivated by the light. I can’t remember the last time I strolled around the ballpark after dark. Usually by that point I’m in my seat watching the game. Thus the results I got tended to emphasize light and architecture.

The picture at the top of this post is my favorite of the set. I love what the 10mm lens did with the sunset. I also love what it did with the curving lines of the ramp. The shot has a range of elements from the industrial stuff at the bottom to the isolated people going about their business to the city in the distance and the sky above.

Funny how the ramp looks different depending on lens and perspective. Here’s another view:

Nikon D7000, 56mm (28-200), 1/60, f/5.6, ISO 800

From the back row of the upper deck, this is what the ballpark looks like:

Nikon D3000, 10.5mm, 1/60, f/2.8, ISO 800, adjusted

When I’ve shot this view in the past I’ve gotten closer to cut out some of the roof, but this time I thought it might be fun to include it. Besides, the large crowd prevented me from setting up much closer.

While I was up top, I noticed that the lights were catching smoke or steam or mist or something:

Nikon D7000, 100mm (28-200), 1/80, f/5.3, ISO 800, adjusted

This shot of the escalators gives you a nice sense of vertical space:

Nikon D3000, 10.5mm, 1/25, f/4, ISO 800

For perspective, note the size difference between the people on the closest escalator and the person next to the bottom.

I was a little disappointed by the Fan Zone (again, maybe I wasn’t in the mood for people shots). But I did manage to capture some fun motion blur from the carousel.

Nikon D3000, 10.5mm, 0.3 sec., f/8, ISO 800, cropped

Despite the absence of a tripod, I got the slow shutter speed to work by bracing my elbows on a rail. Note that the still parts of the shot (such as the picture of the bats in the center) are clear and the moving parts are streaks of light and color. That’s what you’re after in a shot like this.

Pinhole

Nikon D7000, Lensbaby Scout with pinhole optic, 6 sec., ISO 100, retouched

Inspired by an exhibit of Ruth Thorne-Thomsen’s photography at the Nelson, I decided to drag out the pinhole optic for my Lensbaby Scout and experiment with it.

When I first got the optic, I found myself frustrated with the lack of control it entailed. It’s difficult if not impossible to precisely aim a pinhole, so that wasn’t what I was used to at all. I also found the images fuzzy. Uniformly fuzzy, an aperture that small eliminating depth of field pretty much entirely, but fuzzy nonetheless.

After looking at the photos in the exhibit, I was comforted to learn that the fuzziness wasn’t something I was doing wrong. And the aiming issue was nowhere near as big a trick for me and my digital camera (where I could instantly check the results) as it would be for a film photographer or even an artist using light-sensitive paper (as Thorne-Thomsen did).

However, when I opened an experimental shot in Photoshop to adjust the light levels a bit, I noticed something interesting. The picture was speckled with dozens of tiny ghost images of the pinhole. I’d never encountered this before, but I’m assuming the effect is similar to what you’d get with a creative aperture. Click on the image to blow it up for a better look.

Night snow

Nikon D7000, 28mm (Tamron 28-200), 3 sec., f/8, ISO 100

Snow wasn’t in the forecast, but there it was nonetheless. Although it started at the end of a long day, I thought I’d venture forth briefly and get some shots anyway. This picture is the best of the set, and you can see the detail better if you click on it to enlarge it.

If I’d had more time and energy, I would have dug out the camera’s raincoat and installed the lens hood in order to keep the snowflakes off the lens. As it was, however, the blurring from the melting flakes produced an interesting effect with the lights. I was especially fond of the contrast between the fuzzy geometry of the droplets and the clarity of the unobscured parts of the image (such as the tree branches to the left).

The light streaks are from a van that passed through the shot while the shutter was open. With a three second exposure, the dimly-lit van doesn’t stay in any one place long enough to show up in the photo. But its lights are bright enough to leave trails, even when reflected on the slick pavement. The dashed lines were produced by the van’s turn signals.

Happy holidays

Nikon D7000, 10.5mm, 3 sec., f/8, ISO 100

Starting next Monday The Photographer’s Sketchbook will feature our eight favorite previously-unblogged photos of 2012. I actually finished the entries a couple of days ago, scheduled them to run and then put the blog to bed for the rest of the year.

Then the snow hit. Though it was really exceptionally cold outside, I did venture out to the deck to set the tree aright and shoot a few pictures. This one was the best. A low ISO and a three second exposure (thank you, tripod!) allowed me to bring out the dramatic oranges in the sky, a good contrast to the bright blue lights.

And because I can’t seem to shut the teaching thing off (even when I’m on break), here are a couple of other approaches to the same subject.

Nikon D7000, 18mm (18-55), 2 sec., f/8, ISO 100

The exposure here gives me a similar sense of light and color. Indeed, I love the strong blues (which is why I got blue lights for the tree to begin with). On the other hand, the shot composition isn’t quite as good. I also miss the dramatic sky.

Nikon D7000, 10.5mm, 1/4, f/8, ISO 100, Vivitar flash at 1/16 strength

The only differences between this flash-heavy shot and the available light picture at the top are the shutter speed and obviously the flash. At only 1/16 of full strength, the flash creates a nice effect; any stronger and the tree probably would have turned into a blob of bright white haze. I also like the snowflakes frozen in midair. Still, if this was The Shot from this set, I’d be strongly tempted to edit out the bird feeder.
