How to Achieve Picture Perfect Shots via Digital Photography
Gone are the times when photographers had to take several shots of an image and develop them to find out if a fine or even perfect image was taken. Several photographers of this art form refer to this technique as “trial and error”.
Nowadays, there are a numbers of photographers who have decided to shift from regular point and shoot and old SLR models to digital ones. Through DSLRs, they can get more time to concentrate in taking those great pictures since images that are not par with their standards can simply be deleted away.
SLR stands for Single Lens Reflex. The name implies the use of lenses and a mirror. Mirror reflects light entering the lens up into the viewfinder. Thus, a photographer can estimate how the image will likely appear when it is developed. Moreover, a SLR camera uses separate lenses that can be interchanged depending on the resolution needed. Hence, this camera can be used to capture image with varying depths.
Likewise, a digital SLR or DSLR camera uses lenses and mirror. But instead of a film that records the image, a DSLR camera uses light sensor chips and digital memory. In other words, a DSLR camera is the computerized version of the traditional SLR camera.
However, the functions of these models are rather different so it is suggested that users spend time getting familiar or acquainted with these gadgets. Owners should use that “trial and error” technique by taking a few shots and storing better pictures. Sooner or later, users can surely hack these models.
Individuals who decide on using these types of cameras should really invest on memory cards and lenses. Thus, if they happen to become professionals someday, additional equipment will surely keep them busy for choosing photography as a career.
Here are some helpful tips that will definitely aid owners of DSLR cameras in capturing a perfect image using the new art of digital photography.
1. Normally, people take full body shots against a background. However, it is more appropriate to take a shot from shoulders up or an upper body one because image of those in the picture really appear small.
2. If doing the above technique happens to be difficult for the user, he or she can take a shot of the person with him or her at one side rather than at the center. Then the owner can just zoom in so the person appears to be at the center.
3. The law of optics remains the same whether using an old or a digital camera. For instance, if the sun is behind an image, the picture will be silhouette. If light is in front of the image, the picture will appear squint unless there are sunglasses on.
4. Use your sunglass to act as a polarizer to take away unnecessary reflections from glaring objects.
5. You can also use a sunglass to increase the exposure of objects.
6. When using a polarizer, be sure that the source of light is perpendicular to the object.
7. Change your white balance setting from auto to cloudy when shooting bright landscapes and outdoor portraits.
8. Do not use the flash mode when the setting is already sunny.
9. Zoom in to emphasize a certain asset or characteristic of the subject being captured.
10. Practice. Practice. Practice.
It suffices to say that the techniques in getting the perfect shot have not changed. However, using digital cameras and employing this new art of digital photography have simply improved photo shooting by making capturing pictures easy for everyone.
In other words, practice is what really makes perfect shots!

Brightness and Contrast
In photography, exposure is controlled by a variety of things--the size of the lens opening, the film speed, and the duration the lens remains open taking the picture. In digital photo editing, we can adjust exposure further, with the Brightness and Contrast controls.
Brightness, as the name implies, is the amount of light in the picture. The longer the lens was open and the wider the lens aperture, the brighter the resulting picture will be. Every photo editing program will have a Brightness control. Changing the brightness setting will adjust the colors of the pictures as if the photo was taken with a wider or narrower aperture.
However, increasing the brightness can cause the picture to look washed out. This is where Contrast comes in. Contrast is the range of dark and light in the picture--the spectrum between the darkest and the brightest regions of the picture. Changing the contrast will make the brights brighter and the darks darker, which will counter-balance the changes made by the Brightness control. Brightness and contrast are generally used in tandem in most photo editing projects.
In most projects, it's rare to have a photo that needs overall brightness and contrast adjustments. What's more common is to have a picture that needs adjustments to small areas. For example, a dark cityscape against a bright blue sky, or a portrait with sunlight behind the subject, would likely be ruined by changing the overall brightness and contrast. These pictures need smaller, focused adjustments. In the old darkroom days, the only choice the photographer had was to dodge or burn. With modern photo editing programs, however, he can use a Lasso selection set, and then apply Burn, Dodge, Brightness, Contrast, or even Levels and Curves adjustments, to only those parts of the picture that really need it.

Blurring the Background

You can use photo editing techniques to achieve the same effect.
Load your picture into your favorite photo editing program. Using a selection tool like a "Lasso," select the foreground image, the "animal" that has to be set off from the "leaves and branches." Once it's selected, "Invert" the selection. Most photo editing programs have this option. In effect, it means "swap the selected areas for the unselected ones." By inverting, you'll select only the background of your image. If your program has the feature, you might also consider Feathering your selection. This helps to break up the outline of the selection, so that it doesn't have such a sharp edge to it.
Once the background is highlighted, use a tool called Gaussian Blur. This is a specific type of blurring routine designed to imitate the blurring that happens in traditional photography. Don't be afraid to experiment with the settings, but remember that a little bit of blur--leaving the background out of focus, but recognizable--is better than a lot.
A related photo technique is called Panning. Focus on a moving object, like a racecar, and keep the camera pointed at that object as it goes by. Done properly, the racecar will be in focus, while the crowd behind it will be blurred. This kind of blur is called Motion blur, or sometimes Radial blur. Using Radial instead of Gaussian will make your subject appear to be racing past the background.

White Balance and Color Cast
Light has color.
Most people don't realize what difference light sources make in photography until they see the results--and then wonder why the picture looks absolutely nothing like what they remember pointing the camera at.
Light of various temperatures is associated with a temperature in Kelvin. For example, a candle is about 1500 K, a standard light bulb about 3400 K, and the flash on your camera about 5600 K. Light from a sunset, for example, is a rich golden yellow. Light from flourescent bulbs actually shows up as purple in some photos! If you really want your subjects to look like people and not refugees from a planet of purple-skinned strangers, you'll need to keep White Balance in mind.
White Balance is an automatic setting on most digital cameras to account for these adjustments in light sources. Cameras come with a variety of pre-programmed settings. The camera recognizes that if the setting is for flourescent bulbs, then "white" is actually going to look "purple." It will find an example in the frame that it thinks is supposed to be white, and adjust the spectrum for the picture accordingly. Then the picture will turn out with the colors that people expect to see. Unless your picture has wide areas of just one color, it's generally safe to let the camera decide the white balance automatically.
But, if your camera didn't do the white balancing job correctly, then you'll get purple-people syndrome, and you'll have to use your photo-editing program to make up for what the camera missed. Most programs have some sort of color balance control, and the majority of them work the same way the camera was supposed to. Select a point in the picture that was supposed to be white, and the computer will then adjust the entire color spectrum of the picture approprately. Presto, no more purple people.
