Night Photography

Written By Unknown on Tuesday, September 08, 2009 | Tuesday, September 08, 2009


Photography at night can be used to create amazing pictures. For this kind of photography a tripod is almost a must. If you want to get a clear exposure with a great depth-of-field, then you will need a tripod. Usually when we take pictures of sunsets or bright lights we just center all the coloring and shoot the picture.

But something that you should think about doing is adding some foreground item to frame and then shooting which will create a greater depth to the picture, and most of the time make the results look even more brilliant. This picture above was framed with two overhanging trees and a railing. The aperture was very narrow (high f/stop), and the shutter speed was about 10 seconds. Even though a tripod was used, the self-timer was used also, to eliminate any shake.

When photographing sunsets you should not only include foreground items but use the rule of thirds, specifically the horizontal section of thirds so you get a good perspective on the scene. The sunset picture right here was split up into about 2/3's foreground and 1/3 horizon, but this same picture would probably still look good with 1/3 foreground and 2/3's horizon. Also, when you take the light reading with your camera make sure you don't point it directly at the sun, if you do your picture will be underexposed. Take the light reading from the coloring around the sun so you get an exposure that is ideal to accent all the colors.

When trying to photograph fireworks or lightning you will definitely need a tripod. There are different techniques to doing this but probably the easiest is just setting your camera up pointed at a good range of sky and setting the aperture narrow (high f/stop) and setting the shutter speed very long or just by using the "bulb" function of shutter speed (the "bulb" function allows you to open the shudder and close it manually, so its not on a set time). Many people try this in different ways so its just good to experiment and try different things.

Photography Exposure Basics

Exposure is the amount of light collected by the sensor in your camera during a single picture. If the shot is exposed too long the photograph will be washed out. If the shot is exposed too short the photograph will appear too dark. Almost all cameras today have light meters which measure the light in the given shot and set an ideal exposure automatically. Most people depend on the light meter which is fine, but if you know how to control your exposures you can get some creative and sometimes better pictures. (The photo on the left is with low shutter speed and narrow aperture (high f/stop).

The two primary controls your camera uses for exposure are shutter speed(the amount of time the sensor is exposed to light) and aperture (the size of the lens opening that lets light into the camera). Shutter speeds are measured in seconds and more commonly fractions of a second. (1/2000 of a second is very fast and 8' seconds is extremely slow). Apertures are measured in something called f/stops (a very wide aperture is f/2.8 and a very small aperture is f/19).

You might wonder why there is not just a constant shutter speed or a constant aperture so that you would only have to worry about one control. The reason is that even though they both control the amount of light getting to the sensor they also control other aspects of the picture. Shutter speed for example can be used to freeze subjects in midair with a fast speed or it can be used to blur water with a slow speed. Aperture controls the depth-of-field which is what is in focus in the picture. Aperture can be used to draw attention to one subject (like the flower on the right) by blurring the background with a wide aperture (low f/stop). Aperture can also be used to focus everything in a picture with a narrow aperture (high f/stop). (The photo on the left is with Wide aperture (low f/stop) and corresponding shutter speed).

On most digital SLR's (Single Lens Reflex) cameras today you can even change the sensitivity of the sensor when collecting light which is called the ISO speed. The common span of ISO speed is 100 to 800. The higher the ISO speed the faster the camera collects light but it also adds more noise to the photograph than the lower speeds. For example if your trying to take pictures in dim light without a tripod you might want to raise the ISO speed in order to get a picture that's not blurry. Most of the time you should keep it at a lower ISO speed if there is enough light, but it makes a big difference when there isn't.

Low shutter speed and slightly narrow aperture (pretty high f/stop)

Some Basic Tips On Using Your Camera

It's true that taking photos is as simple as running out and grabbing a cheap five dollar camera. But taking good, quality photos has never been easier. So lets explore some quick ideas that can help you take photos that you will be happy to share with friends and family.

Photography as an art has never been more exciting or enjoyable. Todays photography enthusiast has many styles, topics, and tools open to them. Plus, the blending of digital with print makes the craft of taking photos very versatile.

Here are four tips to help.

1. Get a little closer, don't be shy. One of the biggest mistakes most beginning photographers make is shooting from so far away. They leave too much distance between themselves and their subjects. Instead, get up close and personal. Fill up as much of the camera frame, with your subject, as you can. You can always reshape, trim, and resize a good quality shot. But you can't continue to blow up a distant subject and hope that it will come into focus. It just won't happen.

2. This tip springs directly from #1(above)... focus your shot on only one subject. Determine what the main subject of the photo will be, and catch that image. Try and find the one key subject, person, or event that accurately portrays the feeling you are trying to capture.

3. In addition to getting one subject, in your photos, you will want to make the background of the photo as simple as possible. Busy, distracting backgrounds pull the attention away from the central theme of your photo. The subject of your photo is absolutely the most important element, and anything that detracts from the subject can ruin your shot.

4. Finally, you want to take your subject out of the exact center of the frame. You do this by using the rule of thirds. Imagine having a camera lens split into 9 equal sized boxes, 3 across and 3 down (like having a tic-tac-toe game printed right on your camera lens). Where those "tic-tac-toe" lines cross, should become the focusing point of your subject, when you are arranging to take your photo.

Based on this tip, every time you compose a shot, the main subject of your photo should be located primarily on one of these "third" lines.

These are just four very basic tips and strategies to help improve your photos. As you know, photography skills can always be improved. In fact, most professional photographers exhibit a life long passion for learning new techniques, photography angles, and photo inspirations.

Tips for Using a Point & Shoot Camera

Tips for Using a Point & Shoot Camera

source: photo.net

Do you feel inadequate because you have a puny Yashica T4 in your pocket but your no-dick friend is lugging around a Canon EOS-1 SLR, Tamron 28-200 zoom lens, and moby flash?
Don't.

You can get a better picture than he can, for the following reasons:

Your camera weighs 8 oz. and is weatherproof so you have it with you at all times.
You have a decent lens in front of the film; like most first-time SLR owners these days, he has a cheap low-contrast zoom lens.
He is using that moby on-camera flash as his primary light. You would never be that uncreative (at least not after reading the rest of this article).

Your camera has a better system for combining light from the flash with ambient light ("fill-flash").
A professional photographer with a pile of $1500 lenses and a tripod is going to be able to do many things that you aren't. But rest assured that he carries a P&S camera in his pocket as well.
The photo at right shows Bill Clinton handing out a diploma at MIT's 1998 graduation ceremony. I was in the press box with a Canon EOS-5, 70-200/2.8L lens, and 1.4X teleconverter ($2500 total). In the upper right of the frame is a woman with a point and shoot camera. I would venture to guess that her pictures of Clinton are better than mine.
Think about Light


"He spoke with the wisdom that can only come from experience, like a guy who went blind because he looked at a solar eclipse without one of those boxes with a pinhole in it and now goes around the country speaking at high schools about the dangers of looking at a solar eclipse without one of those boxes with a pinhole in it."
-- Joseph Romm
My personal definition of photography is "the recording of light rays." It is therefore difficult to take a decent picture if you have not chosen the lighting carefully. (I've written an entire tutorial on light.)

Just say no
Just say "no" to on-camera flash. Your eye needs shadows to make out shapes. When the light is coming from the same position as the lens, there are no shadows to "model" faces. Light from a point source like the on-camera flash falls off as the square of the distance from the source. That means things close to the camera will be washed-out, the subject on which you focussed will be properly exposed, and the background will be nearly black. We're at a theater. Can't you tell from the background? That's me in the middle. The guy with the flat face and big washed-out white areas of skin. Part of the problem here is that the camera was loaded with Fujichrome Velvia, which is only ISO 50 and therefore doesn't capture much ambient light (i.e., the theater background). [Despite this picture's myriad faults, I'm glad that I have it because it spruces up Travels with Samantha, Chapter III.]
Virtually all point and shoot cameras allow you to control the on-camera flash. What you want to do most of the time is press the leetle tiny buttons until the "no flash" symbol is displayed. The "no flash" symbol is usually a lightning bolt with a circle around it and line through it. Now the camera will never strobe the flash and will leave the shutter open long enough to capture enough ambient light to make an exposure.

A good point and shoot camera will have a longest shutter speed of at least 1 second. You can probably only hold the camera steady for 1/30th of a second. Your subjects may not hold still for a full second either. So you must start looking for ways to keep the camera still and to complete the exposure in less time. You can:

look for some light. Move your subjects underneath whatever light sources are handy and see how they look with your eyes.
load higher-speed film. ISO 400 and ISO 800 color print films are the correct emulsions for P&S photography. ISO 400 film can get the same picture in one quarter the amount of time as ISO 100 film.
steady the camera against a tree/rock/chair/whatever as you press the shutter release
leave the camera on a tree/rock/chair/whatever and use the self-timer so that the jostling of pressing the shutter release isn't reflected on film. I often use this technique for photographing decorated ceilings in Europe. I just leave the camera on the floor, self-timer on, flash off.
use a little plastic tripod, monopod, or some other purpose-built camera support
Yes it was dark in Bar 89. But I steadied the camera against a stair railing and captured the scene with my Minolta Freedom Zoom 28-70. Note that not using flash preserves the lighting of the bar.


Just say yes
Just say "yes" to on-camera flash. Hey, "consistency is the hobgoblin of little minds" (Emerson; slightly out of context).
The on-camera flash on a P&S camera is useful. It just isn't useful for what you'd think. As I note above, it is not useful for lighting up a dark room. However, it is useful outdoors when you have both shaded and sunlit objects in the same scene. Photographic film and paper cannot handle the same range of contrast as your eyes. A picture that is correctly exposed for the sunlight object will render the shaded portrait subject as solid black. A picture that is correctly exposed for the shaded portrait subject will render the sunlit background object as solid white. Here the chess players are being shaded by some overhead screens while the background foliage is not. The on-camera flash makes sure that the foreground players are bright. In fact they are a bit brighter than they probably should be and note the washed-out highlight on the leading edge of the table, which is close to the camera. This picture was taken by prefocusing on the shirtless player on the right, then moving the camera with the shutter release half-depressed to the final composition. Without the prefocusing the camera would have latched onto one of the chess tables in the center of the picture, quite far away. The foreground men would have been out of focus and also tremendously overexposed since an amount of flash adequate to illuminate a far away subject would have been used. [Note that most $1000 SLR cameras would not have been capable of making this picture except in a completely manual mode. Their flash metering systems are too stupid to couple to the focus distance. An exception is the series of Nikon SLRs from 1994 on with "D" flash metering.]

Pressing the little buttons on a P&S camera until a single solid lightning bolt appears in the LCD display will keep the flash on at all times. Note that a side-effect of the "flash on" mode is that you also get the same long shutter speeds for capturing ambient light that you would with "flash off" mode. The standard illustrative picture for this has an illuminated building at night as the background with a group of people in the foreground who've been correctly exposed by the flash. Sometimes it all comes together, as it did here in Coney Island. Without fill-flash, the ride operator would have been a silhouette. Prefocussed on the human subject's face. "Flash on" mode.


Prefocus
The best-composed photographs don't usually have their subject dead center. However, that's where the focusing sensor on a P&S camera is. Since the best photographs usually do have their subject in sharp focus, what you want to do is point the center sensor at your main subject, hold the shutter release halfway down, then move the camera until you like the composition.

Virtually all P&S cameras work this way but not everyone knows it because not everyone is willing to RTFM.
A side effect of prefocusing is that most P&S cameras will preset exposure as well. Ideal exposure with a reflected light meter is obtained when the subject reflectance is 18% gray (a medium gray). Exposure isn't very critical with color negative film, but you still might want to attempt to prefocus on something that is the correct distance from the camera and a reasonable mid-tone. I.e., avoid focusing on something that is pure white or black. This becomes much more important if you are using slide film.

Burn Film
If a roll of film is lasting three months, then something is wrong. You aren't experimenting enough. An ideal roll of film for me has 35 pictures of the same subject, all of them bad. These prove that I'm not afraid to experiment. And then one good picture. This proves that I'm not completely incompetent.

It takes at least 10 frames to get one good picture of one person. To have everyone in a group photo looking good requires miles of film. You should have pictures from different angles, different heights, flash on, flash off, etc.

My personal standard film for P&S photography is Fuji ISO 400 negative film. It enlarges very nicely to 8x10 and is great for Web presentation.

Try to Buy a Decent P&S Camera
You can read my buyer's guide. Basically what you want is a reasonably wide angle lens to capture your subject and the background context. Focal lengths beyond 70mm in P&S cameras are not useful. My personal ideal camera would have a 24-50 or a 24-70 zoom though actually in many ways I prefer a camera with only a single focal length because it is one fewer decision to make at exposure time. Zooms are more useful with full-sized SLR cameras because the user interface is better/quicker (i.e., you can turn the ring on the lens instead of pushing little buttons to drive a motor).
