Digital Cameras & Resolution
While analyzing any camera, one of the most important qualities of a photograph that a person seeks, is resolution. This word itself needs a brief discussion before progressing onto its implication upon a digital camera. This is a word that seems to almost every new photographer as a nightmare. With all the myths and irrelevant information circulating all around, this is quite common. This however is an effort to clear those misty myths and provide good information for everyone. Without any complexity, generally a photograph, either viewed on the screen or printed, is composed of infinitesimal dots (called pixels). The greater amount of these dots that can fit per inch of space, the smaller the dots and the sharper the image. This is the basis of understanding ... resolution! Considering an image at 100 dots per inch that is one square inch in size. It is comprised of 100 X 100 pixels. Now changing this image four-times to four square inches. This image is quite clear. Now the same 100 X 100 dots exist, but with only 25 dots per inch. The appearance becomes grainy. This is the factor know as resolution that determines this quality of image. Hence it can now be interpreted by any person what the importance of resolution is and where it is required in the filed of photography. While purchasing a digital camera, resolution is a very important factor to take into account when settling upon buying a particular one. Digital camera resolution comes in as Mega pixels. A Mega pixel is composed of one million pixels. The greater the number of Mega pixels, the greater becomes the standard of quality of the photograph or picture. As a standard, one mega pixel is the minimum bottom line below which a digital camera must not be usually purchased. This is a general decided value for any amateur photographers also, and the exact value of higher mega pixels is not a concern for people who do not intend to print the photographs. In an effort to scrutinize the pixels in an image out of sheer anxiety, a person can magnify the display in a photo editor, like a little magnifying glass, and they become very much visible! The resolution decides the ultimate the future of the hard copy of a photograph being taken, whether a digital camera or a conventional camera. A print from a high-resolution photograph challenges anything produced from a chemical film camera. However a low-resolution image print of a photograph is quite appalling with fine details and restrained color transitions absent resulting from too few pixels. Thus the resolution can spoil an entire effort to freeze a memorable moment. Thus it is so vital. As a general rule a minimum of 200 pixels are required for each linear inch of a print. However, some printers get better results with 300 pixels per-inch of resolution. The above discussion has brought into light a lot of relevant information regarding resolution and its application in the digital camera and photography. Also in the concluding lines it can only be stated for digital camera ... resolution is the real soul! About The Author Jakob Jelling is the founder of http://www.snapjunky.com.

The Photography Portfolio: Building Your Reputation If you have hopes of becoming a professional photographer, or even just of trying to get your work published in a public forum, you will need to create a photography portfolio. So what's so important about a photography portfolio anyway? How a Digital Camera Works The digital camera is not something of a magic box that came out of the blue and made wonders! The digital camera is very much like the conventional analog camera, but the technology has been altered. It also contains most of the associated components that the conventional camera contains, like lens and a shutter for letting in light, however instead of reaching a photosensitive film, the light is made to fall upon array of image sensors or photosensitive cells. Much of the differences are like this, yet most of it still remains in oblivion for the ordinary people. And it order that the digital camera gets its true respect, it is necessary to explore these areas of truth and reveal them in light. Travel and Scenic Photography 101 When you're driving through the mountains somewhere, and you notice a car parked half off the road and some guy leaning to the left to avoid a branch with his Rebel 2000 camera in the act of focusing, you've met me. I do this because, to me, a trip isn't fulfilling unless I've preserved that beauty for posterity. I'd like to share some of the techniques that make scenic photography such a wonderful artform - simple, yet elegant.First off, equipment. As much as the cheapo disposable camera beckons, get real. These cameras have fisheye lenses which I call "spam" lenses. They cram everything in, with equal blurriness and boringness. Good photos are sharp, unless you use blur for artistic effect. Sharp comes from an adjustable lens. It can be a fixed lens or a zoom, but it must focus specially for each picture. Fixed lenses are limiting for scenic pictures, where to frame the shot you may need to move long distances. Imagine using a fixed lens on the Washington Monument, when you're half a block away! Zooms get my vote, even though they often don't have as wide an aperture, which limits their capabilities in low light situations. Practically speaking, an SLR is the absolute best. They are lightweight, and can be used with top quality lenses. Film SLRs tend to be less expensive, but have the limitations of film, meaning you have to get it developed and so forth. Digital SLRs are VERY expensive, so for the budget conscious either go with a film SLR or a high quality basic digital camera. With digital, resolution is also a critical factor, so look at the specs before you buy.OK, we've got the camera, emotions are running high, and that's great, but not too great! Sometimes I find a spot that is so wonderful, I start shooting like a madman, only to be disappointed by the pictures. What happened? Emotions. When you experience a place, there are sounds, aromas and breezes as well as the visuals of the spot. Needless to say, you can't photograph all of these elements, only the visual. When overwhelmed by the spectacle of a scenic hotspot, we are often overwhelmed by all of these elements.So what to do? Look through your camera. The viewfinder does not lie (usually). Try to see what you are looking at as the finished picture. Most people perfunctorily take pictures, hoping that somehow the shot will come out great. If you wonder how the pictures came out when you are on the way to the drug store to get them, you're doing something wrong. At the moment you click the pic, you should know exactly what you will get. (Of course with digital, that's not a trick!). Now, I was a tad dishonest in saying that you can't capture all of the elements of a scene. You can hint at them. For starters, motion. Yes, even in a still picture, there is motion. Something happened before, during and after your picture. In a mountain vista scene, you may find something that hints at motion, whether it be a branch of a tree that has been swaying in the breeze, or a river flowing through the valley below. These add a sense of motion. Then there's the "rule of thirds." When you place the main object of the picture smack-dab in the middle, it is static and boring. Place it one third of the way from either side, and you IMPLY motion. Put the horizon in a landscape photo a third of the way up or down, not across the middle.Remember, when a person looks at a picture, their eyes move. You want to frame your photo to help that movement. If you can find some lines in the scene, such as a skyline, cloud formation, path through the forest, etcetera, use it interestingly, and with the rule of thirds to draw your viewer's eyes into the picture.Avoid "summit syndrome." You get to the top of Mount Washington and shoot the majestic vista. Great. The pictures come out ... boring! How? No PERSPECTIVE. Big vistas will be flat unless you have an object in the foreground, such as a rock or a tree, to give them perspective. Then the eye really grasps how big this scene is. People enjoying the view is a real winner, because the viewer may identify with their emotions, giving the image real impact.Cheese! Yes, you do have to take the family photos. It's obligatory. But when you do, make sure that they show the LOCATION of the photo. Otherwise, you might as well do it on your driveway. Frame the scene in context, with landmarks as part of the picture. Find a way to tell as story in the picture, such as little Sara climbing up the rocks by the waterfall.Finally, any element in the picture that hints at more senses than just the visual will make it remarkable. Actor headshots for example, tell a story about the subject. You can almost hear them saying their next lines. If you photograph a garden, the viewer may experience the aroma of the flowers. A tourist street with an accordion player on the corner may have your amazed friends whistling "Dixie."In summation, picture taking on travel is recording the experience in a satisfying way. Use motion, perspective, sensory, storytelling and so forth, to bring your photos to life. Oh, and needless to say, make your job easy and go to great places! See you at the overlook!
