Digital Camera Reviews and Ratings De-Mystify the Choices
Shopping for a new digital camera can be quite frustrating with the hundreds of choices available. Digital camera reviews clarify this confusion by comparing camera features and options, then rating how each camera compares with similar models. An effective comparison of best digital cameras requires two things: 1) the camera's specs and features, and 2) performance ratings. Spec sheets and ratings are plentiful, but to efficiently compare digital cameras it's important to set some guidelines. Decide on how the camera will be used, the quality and size of final prints, and necessary features. Write these down and rank camera reviews and ratings against these standards. Whether looking for a professional or snapshot camera, scan the reviews and narrow your choices down to a few cameras before making final comparisons. OK, Lets Cut to the Chase... Re-visit the reviews for this short list and evaluate the digital camera ratings in more depth for the following criteria: Design, Construction and Controls Minor design differences can become significant in daily camera use. Carefully compare how each camera's review is rated for design elements. Size and weight, body configuration, plus location of buttons, knobs and other controls can make a camera a joy to use or a real pain in the neck. Evaluate how well the camera is put together. Are access doors for battery, memory, etc. solid and stable? What does the reviewer say about the shutter release, zoom and other buttons and knobs? How many photos will a fully charged battery take? Is the LCD bright and clear in both low light and sunny conditions? The reviewer's evaluation of the camera's controls is critical. Can manual adjustments be made for different lighting conditions? How about auto-focus zones and exposure modes? Are controls simple and intuitive, or complicated menus? Sensors, Pixels and Processors These are the heart of a digital camera and determine photo quality, so closely compare how the reviewer rates them. Generally larger sensors have more powerful and efficient photodiodes, and will produce higher quality photo images. Both CCD and CMOS sensor technology is advancing rapidly, but with each new development there are usually draw-backs, so compare carefully. Digital camera marketing would have us believe it's all about more megapixels. But it's more complicated than that. Evaluate how each camera's review rates pixel quality, not just quantity. Some cameras will actually take better pictures with fewer pixels. What the camera's processor does with the data collected from the sensor's diodes is equally important. It must properly interpret color balance and interpolate pixels for sharp natural looking pictures. It must be able to do it quickly or you'll have to wait too long between shots. Lens Optics In many ways lenses for digital cameras are simpler and less expensive than for conventional 35mm cameras. Even so, sensors and processors can't produce a better photo than what's visible through the lens. Compare the ratings because cheap lenses can distort images and colors. In conclusion, decide on camera basics and budget range, scan enough reviews to pick a handful of finalists, then scrutinize the reviews and ratings on those cameras to find the perfect choice.

Nude Art Photography Nude photography is the genre of art photography, whose subject is the representation of the naked (full nude) or partially naked (half nude) human body. Light and Depth of Field With such a fantastic device as the digital camera for the recreation of magic in arts, a lot of care needs to be taken so as to maintain the perfection of the end product. This perfection is not only obtained by the artistic feeling of the photographer but also with the intricate knowledge of every minute aspect of the medium of creation of art (in this case the digital camera). And these minute aspects play a vast role in defining the ultimate perfection. The digital camera, light and depth of field are one such factor that would come into light in this subsequent discussion. Basically, the depth of field is a measurement of the acceptable sharpness. Yet this is very strictly a personal preference, and varies from person to person. Camcorder Techniques: How To Make Home Movies Your Family And Friends Will Be Excited To Watch Pre-Production: 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? Understanding Digital Photography Most serious photographers and all professionals use a Single Lens Reflex camera (SLR), the definition of an SLR camera is that the image is captured exactly as you see it in the viewfinder. However there are now two types of SLR the single lend reflex film (SLRF) and the single lens digital (SLD). They are both single lens camera, but digital does not use film and the resulting image can be processed at home with the aid of a photographic editor such as the chemical component in a traditional camera is film. When film is exposed to a real image, it makes a chemical record of the pattern of light, coming through the lens. Film has a collection of light sensitive frames, suspended on a strip of plastic. Colour film has three different layers of light sensitive material, which respond to red, green and blue (known as the (RBG) values. When the film is developed, it is exposed to chemicals, which dye the separate layers of film, into a color negative. All modern film is made up of silver halide crystals. Elephants in the Sky and Four Poems Elephants in the Sky Digital Photography: The RAW vs JPG Debate If you use a digital camera (I use a Canon EOS Digital Rebel/300D myself) and that camera is an SLR, then it most likely can record images in RAW format. In general, you should record your images at the highest resolution possible. If you only have a small memory card and are worried that you can only record a few RAW images on it, then it's time to buy a bigger card! [They don't cost much these days]. You can always shrink an image after it's taken but you can't enlarge a small one without introducing artifacts. At the very least, you should have your camera record images in Hires JPG format but RAW format is even better. Extreme Digital Photography: Beyond Point-and-shoot When my old Olympus digital camera got broke while caving during a family camping trip, I had mixed feelings. For quite some time I had felt that the quality of some of my pictures was hampered by the limitations of that camera, but I did not look forward to spending the money on a new one. Take Spectacular Nighttime Photos with your Digital Camera - Part I Night photographs express a special something that cannot be seen in normal daytime photography.

Baby pictures can also make great postcards, keepsakes, or baby shower gifts. Here are some simple tips to get great baby pictures: Specialized Styles of Photography Outlined below is a list of genres that call for specialized treatment in the process of creating outstanding photographs. These thematic approaches will be discussed in detail here, though there are few more categories and sub-categories in thematic photography like ad messages, corporate brochures, under-water photography and so on. 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! How to Buy the Right Digital Camera When buying a digital camera there are many things you should consider. First you should understand how a digital camera works. What you are using your digital camera for will help you decide what features to consider and how much you should spend. I am here to educate you and help you decide. The Mysterious Powerful Element of a Picture That Sells A photo buyer calls for a picture of pigs. It could be about anything. A hundred responses go online and one lucky so-and-so gets the sale.

Getting The Right Digital Camera For You There are really great advantages in digital photography: Photography Poses ? The Missing Ingredient You've read all the "best digital camera" articles, got the best price on your first digital camera, and even glanced at its owner's manual. Are you itching to take some shots of your family, or what? What Should You Look for in a New Camera? These parameters are discussed at 2 levels: -Based on degree of functional use of available features -Based on the type of photography you want to attempt -->Based on degree of functional use of available features A person who is happy with his or her camera model usually responds with the following words of praise. 'Incredible ease of use' 'User-friendly controls' 'Intelligently and thoughtfully designed' 'Excellent value for money' 'Light and compact' These are the kind of terms that you will come across from camera owners who are satisfied with their camera models. These superlatives sum up what people usually look for or could look for at an overall level in their camera. It is a broad evaluation based on design elements, size and affordability. Before you make a decision to purchase you should explore a little further and study the type of features available to you. Unless you make the attempt to understand the features at your disposal, there is the risk of being stuck with a model that does not suit your particular requirements. Let's take a look at what features you should look for, as well as the features that you should be wary of when you choose a camera system. -->Features to Look For 1. The lens is by far the most important device in your camera. The quality of the lens ensures the sharpness of your image. The camera lens is described by length (given in mm), known as the focal length of the lens. 50mm is the standard focal length in a lens. A lens of shorter length is known as a wide-angle lens and is used usually by landscape photographers. A lens with focal length greater than 50mm is called a telephoto lens and is especially useful to professional photographers in capturing distant images. There are also cameras with a zoom lens. A zoom lens can offer various focal lengths, so you have a lens capable of many focal lengths. Simple put, when you use a zoom lens you can make your subject bigger or smaller within the frame. For instance, a wide-angle zoom can cover a range of focal lengths below 50mm, or a telephoto zoom gives you a range of higher order focal lengths. Some superior zoom lenses can take you from wide angle to standard and through to telephoto ranges. The power of the zoom lens is defined by the extent of magnification from a lower focal length to a higher end and is given as 2x, 3x and so on. Some lens tips: --A 50mm or 100mm lens is considered adequate for most non-professional hobby users. The professionals usually go for telephoto lenses of 200mm or more. A lens with higher focal length costs a lot more. Most beginners don't need to invest in a telephoto lens. --Check if your camera is compatible with the range of lenses that the manufacturer of your model has on offer. Most manufacturers have hundreds of lens options on offer and your requirement for lenses varies as you progress in photography. Your camera has to be compatible with lenses of higher focal length and speed. If you are planning to upgrade your camera by buying another model from the same manufacturer, check for compatibility with older accessories so that you can put to use some of the lenses already available with you and save yourself an additional expense. 2. Depth-of-field preview button A depth-of-field preview button is a necessity if you want to achieve better focus. It allows you to identify the area that will be in focus in your photograph. This area is referred to as the 'depth of field'. When you adjust the focus in your camera the preview button is a useful tool that can help you vary the focus and depth of field in different shots. 3. Image sensor resolution In digital cameras, there is no film in use but this is instead replaced by a device called the image sensor. The image sensor renders colors, is sensitive to light and is the device that captures images in small pixels on its surface. Image resolution is a measure of the sharpness or level of detail in photographic images. Image resolution is expressed as a number and is measured in mega pixels. High-end professional use cameras have an image sensor resolution of around 12 mega pixels and the most advanced professional models go up to almost 14 mega pixels. At the mid range you have camera models with resolution ranging from 2 - 6 mega pixels. To deliver large format prints of superior quality, you should go for models with resolution greater than 3 mega pixels. At the lower end, you have models of 1 mega pixel or less and the sharpness of the photograph is slightly inferior compared to cameras with higher values of image sensor resolution. Lower pixel models are best suited for small format prints. 4. If you have the facility for Auto-bracketing it can be a very useful tool. Auto-bracketing enables the camera to automatically take 3 exposures or in some cameras 5 exposures of the same shot by varying the Exposure Value (EV) to lighten or darken an image. Each of the images will be slightly differently exposed and this is a great tool to ensure that you capture the moment perfectly. You can bank on at least one being a properly exposed picture. This tool comes in handy especially for professional photographers. 5. If tonal quality of the photograph is your top priority when you choose a camera then it is best that you go for a digital camera. Photographic prints of scenes captured on a digital camera have a level of tonal quality that is far superior to best quality traditional prints. 6. There are sophisticated camera models available today that can capture movement and audio-visual images. If you want to go beyond static images and capture the first steps of a child or activities during family get-togethers, then you should look for a camera with these advanced capabilities. It will create a better experience when you go down memory lane. The Kodak Easyshare LS753 Zoom Digital Camera is one such model that offers audio-visual capability. Sony Digital Cameras - Always On The Innovation Frontier Sony was the first company to introduce digital cameras into the market. Today, Sony is one of the leaders in the digital revolution.
