Reducing Lens Flare From Streetlights
Discussion: 0Sooner or later, you are going to run in to lens flare when doing urban night photography. Frequently you will want to capture a building, fixture, or other item that is inconveniently located near a street light. While there are ways to control it, it usually isn’t possible to eliminate it altogether, depending on how close you are to the light source and how much of it is in the composition.

The first photo illustrates a case of very bad flare. It was a very long exposure, which meant the very small aperture. A small aperture will focus light as it goes toward the sensor from the lens, and will cause the light ray to bounce around within the camera. This causes multiple flares, sometimes in different colors and usually in the shape of a hexagon. This hexogonal shape is the result of the lens diaphram. The number of sides in the polygon is determined by the number of blades in the diaphragm itself.

Create Surreal Images With Longer Exposure Times
Discussion: 1One of the greatest secrets of creative night photography is not a long exposure, but a longer one. This is what I refer to as the sweet spot exposure because it’s a small range of exposure times–typically longer than 1/10 of a second but shorter than 1 second. The reason this is such a great range is that it typically creates movement and blur, but not so much so that only light trails are seen. I’ve written articles on this before, such as freezing people in movement and combining flash and slow shutter speed.

In the photo above, leaving the shutter open for half a second allowed a good bit of the red-colored bus to be shown, but also blurred. This length also allowed the people behind the bus to be partially exposed as well.

Rain Is An Opportunity
Discussion: 1Conventional wisdom says that when rain is here, you stay inside. There is good reason to avoid rain–any amount of water in the electronics of your camera can magically turn it in to a doorstop or paperweight.
With the proper preparation and care, however, you can get some great and not-so-usual photos that take advantage of the unique properties of light and water refraction.

When it is raining, misty, drizzling, or otherwise precipitous outside, light refracts off of the water in the air, creating a soft glow on everything that is illuminated.

In my opinion, the best part of photography in the rain is not the refractive effect, but the reflective effect. When pavement becomes soaked, it acts as a weak mirror to light sources around it. The photo above is an example of the reflective properties of water. The lights in the photo above are more noticable on the reflection source than they are at the light source itself.

An example of refraction and reflection acting together is from another source you may not think about–the sky. Clouds bringing the rain will reflect light back down towards earth (making the sky visible) in addition to projecting a soft, dark glow (from the moon, perhaps?). If you shoot in the city, stars in the sky are hard to come by. However, you can get an interesting looking sky when there are clouds overheard and a mist in the air.

The last idea I’ll convey about rain is capturing people. Think about the last time you were at the grocery store during a downpour. How many people did you see slowly moseying about towards their car? Chances are you saw people running, hopping, or jumping quickly over water puddles. When it rains out, you get a chance to capture people unlike they are in most situations. When shooting at a wide angle, set your shutter to 1/4 second or faster. At this speed you will capture them in some form–probably blurred. The faster the shutter speed you use, the more clear the images will be of the person in motion.
How can you keep your gear safe while capturing life out in the rain? It isn’t easy, I’ll admit. I usually go out driving in the rain, and wait for a lull in the action to get out of my car and get a few shots. It may be possible to set up your tripod in the car, but it will be cumbersome and you will be severely limited in the shots you can get. Your best bet is to carry an umbrella, and look for overhangs and awnings. Getting a few drops of water on your lens or camera body won’t spell certain doom. I’ve been caught out in torrential downpours on many occasions with nothing to protect my camera with. The amount of leeway you have is determined by the environmental protections offered to you by the camera manufacturer. Lower end DSLRs will have less weather protection than the higher end ones. If most of your camera is wet from rainfall, you want to avoid further contact with water and either protect your gear or wait for a slowdown in the rain.
Like so many other things in life, the most rewarding actions carry a proportional amount of risk. Small amounts of water = okay. A drenched camera = damaged electronics beyond repair.
Photographing A Concert Without A Tripod Or Flash
Discussion: 4Under ideal conditions you want a tripod, but in many instances there isn’t enough room to lug one around. A monopod is another option, but even that can be problematic in large crowds. Many venues/bands simply won’t allow flash photography as it’s distracting, especially with many of them going off. Your only option: handholding in what is normally very low light conditions.
Please note: not every concert is the same. All venues are slightly different, and all shows have different properties with regards to lighting, effects, etc. This article tries to make some generalizations, but obviously some of the advice presented here can be adjusted according to the situation. In many cases it’s an unknown with regard to what the club or venue will allow you to carry in, what the lighting will be, and how crowded it may be.
Lenses
Do you have a 50mm f/1.8 lens in your arsenal? If not, it should be your next purchase. They are made by both Nikon and Canon (and I assume others) and as far as lenses go, very inexpensive. I bought mine brand new at a local camera shop for $90. Having an aperture of f/1.8 really opens the possibilities. If you don’t have a “nifty fifty”, you want to bring your widest-angle lens. Having a wide angle lens makes it easier to photograph in low light, as more ambient light is caught by the sensor, requiring a shorter exposure time. A telephoto in low light conditions with no flash or tripod is pretty much out of the question, unless it’s outdoors during the day. I am also making the assumption that you have a digital SLR camera.

Artificial Movement And Long Exposure
Discussion: 2It’s no secret that when you leave the shutter open for more than a second you can get some neat effects when light is moving against a dark background. Many people experiment with this in the usual way with moving cars and rides at the state fair. I still do regularly, in fact. What many people may not know is that you don’t need the light to be in movement to create something unique.

For the photo above, I popped the flash with a 6 second exposure. After the flash went off, I then tilted the camera while still on the tripod. I didn’t try and do anything specific, I just slowly moved it short distance in a few different directions. The phrase less is more applies tremendously to this particular way of capturing light. It’s very easy to overdo it and create a picture that is just a bunch of squiggly white lines. Simply rock the camera forward and backward on the tripod while two out of the three legs are still on the ground. Try moving just a few inches in each direction.

Simulating Multiple Exposures
Discussion: 0In the old days, you could get a multiple exposure photo by opening and closing the shutter while not advancing the film. While I’ve heard that there does indeed exist a digital SLR that can do this, my ancient beast isn’t one of them. When looking up the topic when I first upgraded to digital, most examples I found were using post-production (Photoshop) to do this. I’m going to show you how to do this using a hand-held flash unit (Canon Speedlite 430EX was used in the examples below), some colored gels, and a tripod.

For this particular type of photography, you want to stay focused on the exposure time rather than the aperture. You will need at least 4 seconds to get a double exposure, as seen in the photo above. I tend to stay in the 15-20 second range, depending on the amount of available light. The camera setting I recommend most is Tv, or Shutter Priority. This mode allows you to change the exposure length while automatically adjusting the aperture. It’s a delicate balance trying to determine the proper length of time to leave the shutter open. You will need enough time to reposition the flash and/or wait for your subject to move. On the other hand, if you leave the shutter open too long, the subject may barely be visible, even if you popped them with the flash. It is also important to hand hold the flash unit. Not only does light from above look more appealing and real, but it’s more difficult to pop the flash twice during one exposure when mounted to the camera (with my setup, at least).

Using The Wind To Your Advantage

This is the Fannie Heck house on Blount Street, in Raleigh, NC. It dates back to shortly after the Civil War. There was plenty of available street light to get a 4 or 6 second exposure with the same ISO, but bumping up to the maximum (didn’t have release cable with me at the time) non-bulb setting (30 seconds) allowed me to get the cat tails flowing in the wind while everything else sat still.

Make Strangers More Interesting
Discussion: 0To make complete strangers more interesting subjects, you have to deal with a few trained reactions. What’s the first thing you do when someone is taking a picture of you? Usually you smile and look directly at the camera. If you are looking for something beyond what you’re used to seeing, you want to try and capture something other than that familiar photo.
There is nothing with smiling and looking directly at the camera. Those pictures are great for people you know. The problem is that when you are photographing complete strangers, they won’t feel at ease with you enough to let out a genuine smile. Trying to achieve this can be painful and/or embarrassing.

Flash and Slow Shutter Speed
Discussion: 1![]()
EXIF: 200 ISO, 2 sec., f/4.5, 17mm focal length, no flash
Using a flash is known to freeze items in motion, whereas slow shutter speeds are known for conveying motion. You can combine the use of flash with a slower shutter speed to create unique and distinct effects. In the image shown above, the front half of the train’s engine was caught with the flash, but the rest of the train was not. It froze the engine in motion, but blurred the rest of the cars. Additionally, the street lights in the area provided a very warm color temperature.
