Digital Photography - Exposure Settings and Tips

Posted in DigitalPhotography by admin

Exposure is the amount of light collected by the sensor in your camera during a single shot or photograph. If the shot is exposed for too long a time the photograph will be washed out. If the shot is exposed for too short a time the photograph will appear too dark. Almost all cameras today have light meters which measure the light in the given composition 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 greatly improved pictures.

-Aperture and Shutter Speed

The two primary controls your camera depends upon 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 narrow aperture is f/19).

You might wonder why there isn’t 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 designate 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).

-ISO 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 1600. 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. Different cameras make different amounts of noise in photos so I would definitely experiment with your cameras ISO settings so you will know what to expect when it matters.

-White Balance

Most people don’t experiment with or use the white balance function on their cameras. White balance is simply a function where the photographer has the option of designating what parts of a scene are white so the camera can adjust to the other color temperatures accordingly. Almost all digital cameras today give the photographer the option of manually setting the white balance which can sometimes be hard if you don’t have a white or grey card. Many new digital cameras have a set of preset white balances for certain types of scenes such as snow or clouds. I have found that using the preset modes is almost just as effective as setting the white balance manually so I would definitely advise others to keep the preset white balance modes in mind when they are using their cameras.

-Time of Day

The time of day is usually what determines how much light you are going to be working with. In the early morning and the late afternoon there will be less light than in the middle of the day. During this time there should be enough light for most kinds of exposures except if you are trying to catch an object in motion. If you are trying to catch sports photos or objects in motion you will have to adjust the aperture and maybe even the ISO speed (both of which are discussed in this article) in order to be able to use the necessary shutter speed. In the middle of the day (with typical weather) the light is very bright and you should be able to use any shutter speed or aperture that you want at the lowest ISO setting. At night it is a totally different story if you are not using flash. If you aren’t using flash and are taking photos at night probably with a tripod then you should set the ISO speed very high and you will need a very long shutter speed and a moderately wide aperture.

To become comfortable with exposure settings is a very difficult task. But if you master exposure enough to know what you should use for each scene, then you could become a much more professional photographer.

8 Simple Tips for Taking Great Baby Photos

Posted in Photograpy by admin

Taking pictures of your new baby is a great way to preserve life long memories. Baby pictures can also make great postcards, keepsakes, or baby shower gifts. Here are some simple tips to get great baby pictures:

1) Avoid bright light - Babies are especially sensitive to bright light including harsh sunlight and flash photography. If possible, try to take photos during the day when flash photography is not necessary. You can also use lamps to create lighting.

2) Take pictures from different distances - Try to take pictures from different distances. Most people like to take closeup pictures, but pictures that are too close can be blurry and out of focus. By taking several pictures from different distances, you can keep the ones that are the best.

3) Be aware of your baby’s mood - Try not to start a photo session when your baby is cranky or crying. If your baby is in a bad mood, then wait awhile until he or she is better rested or calmed. You will get better pictures when your baby is in good spirits.

4) Use a high quality camera and film - This tip may seem simple, but is worth saying. Using high quality cameras and film can make a big difference in the quality of the photo, especially if you are creating photo gifts or favors.

5) Get rid of any distractions - Make sure there are not too many distractions when taking pictures. Anything that moves or makes noise, like the TV, should be turned off is possible. Having too many people around can also be distracting for the baby.

6) Take multiple shots - Taking different shots is a good idea for any type of photography, particularly if you are making photo gifts. Sometimes it is hard to tell if a shot will turn out good until it is actually produced, so get those extra shots just in case.

7) Background - Make sure that there is not too much distracting stuff in the background. The focus should be on the baby, so plain backgrounds usually work best.

8) Other people - Try taking pictures of the baby with other people as well, including yourself. A baby will interact with other people and these interactions captured on film can make great keepsakes.

Photography - Rules of Composition

Posted in Photograpy by admin

Composition is defined as the combining of distinct parts or elements to form a whole. In photography that definition is very important in taking quality pictures. The following rules of composition should be learned and considered but not necessarily used in every photo. Once you have learned these rules you will be more observant of the possible photo opportunities that surround you. But keep in mind that the really famous photographers usually find a creative way to stretch or break the rules of composition.

RULE OF THIRDS

The rule of thirds has been used through the centuries and is probably the most recognized rule. The rule of thirds directs that the frame can be divided into three vertical sections and three horizontal sections. Wherever the separating lines connect is an ideal spot for a subject or point of interest. By positioning your main subject at any of the four intersection points, you are giving your subject more emphasis than if it is right in the middle of the photo. The intersection points can also work if there is more than one main subject in a photo. Most famous photographs and paintings have the rule of thirds applied to them in some way or another.

SIMPLICITY

The simplicity rule directs that you should keep the items in your photo relatively simple. If your main subject is close to the lens, then your background should be very simple in order to avoid distractions. Another good idea is to avoid objects or lines that lead the eye away from your main subject.

CONTRAST

The contrast rule directs that light subjects should be placed against dark backgrounds and vice versa.

FRAMING

The framing rule directs that using natural surroundings mindfully can add more meaning and focus to your subject. The surroundings could be anything such as bushes, windows, trees or even a doorway. When using this rule be sure to focus on the main subject and not on the surroundings that are framing it. It is also a good idea to use a narrow aperture (high f/stop) when using this rule in order to create a high depth-of-field.

TEXTURE

The texture rule can add a great amount of interest to most photos. When people see texture in a photo it can spark their imagination and make the photo more real to life. Texture would be a good idea when taking photos of rocks, walls, surfaces, hands or even leaves. In order to create texture try to compose your photo so the light is coming from the side and therefore casting shadows in key places.

DIAGONALS

The diagonal rule directs that diagonal elements or lines can make a photo more dynamic. Diagonal elements could be fence posts, roads or even tree branches.

LEADING LINES

The leading lines rule can be used to direct the eye deeper into a photo and commonly to the main subject. Leading lines can lure the eye to a subject by leading to it from any side or depth of the photo. Leading lines could be roads, rivers, tree branches or even bridges.

COLOR

The color rule is what adds interest and emotion to your pictures. Different color configurations can inspire and amaze viewers. Colors can also be used to accent certain parts of a photo.

It might not be a bad idea to keep these key terms with you when you practice taking photos. The best way to learn and improve your composition is just to use them often and to experiment.
