The Benefits Of A Digital Camera

By Obinna Heche

 It is a well know fact that digital cameras can do things film cameras cannot, displaying images on a screen immediately after they are recorded, storing thousands of images on a single small memory device, recording video with sound and deleting images to free storage space. They are incorporated into many devices ranging from pdas and mobile phones called camera phones to vehicles. They have high power requirements and over time have become increasingly smaller in size, which has resulted in an ongoing need to develop a battery small enough to fit in the camera and yet able to power it for a reasonable length of time.

Compact cameras are actually designed to be small and portable. The smallest are described as subcompacts or ultra compacts. Compact cameras are usually designed to be easy to use, sacrificing advanced features and picture quality for compactness and simplicity. Images can usually only be stored using lossy compression jpeg. Compacts often have macro capability but if they have zoom capability the range is usually less than for bridge and dslr cameras. They have a greater depth of field, allowing objects within a large range of distances from the camera to be in sharp focus.

Most cameras on the market today have sufficient resolution for your needs. Bridge or slr like cameras are higher end digital cameras that physically resemble dslrs and share with them some advanced features but share with compacts the framing of the photo using live preview and small sensor sizes. Bridge cameras often have super zoom lenses which provide a very wide zoom range which is attained at the cost of some distortions including barrel and pincushion distortion to a degree which varies with lens quality.

These cameras are sometimes marketed as and confused with digital slr cameras since the appearance is similar. Bridge cameras lack the mirror and reflex system of dslrs, have so far been fitted with fixed non interchangeable lenses although in some cases accessory wide angle or telephoto converters can be attached to the lens and can usually take movies with sound and the scene is composed by viewing either the liquid crystal display or the electronic view finder. Many of these cameras can store images in lossless raw format as an option to jpeg compression.

Nevertheless, most manufacturers of digital cameras do not provide drivers and software to allow their cameras to work with linux or other free software. Still, many cameras use the standard usb storage protocol and are thus easily usable. Digital cameras have high power requirements and over time have become increasingly smaller in size, which has resulted in an ongoing need to develop a battery small enough to fit in the camera and yet able to power it for a reasonable length of time.

The zoom lens reflex cameras sometimes referred to as zlrs, megazooms, ultrazooms, or bridge cameras are designed to be an intermediate step between compact digital cameras and dSlrs. They are larger than compacts but offer more versatile manual controls and lens systems including greater zoom capability. Unlike the typical digital slr, they do not have interchangeable lenses but filters and adapters can be used on many megazoom cameras. Optical sharpness is attained by physical movement within either the camera body or the lens element which compensates for handheld shaking.

Sort your favorite digital cameras by brand or by megapixel, compare cameras and buy one for a cheap price via online retailers. Photographers who want to go beyond basic point and shoot digital cameras should look for more robust features, such as manual exposure modes, several different metering mode choices and the ability to use accessories such as adapters, lenses or extra flashes.

Digital Photo Recovery Explained

By Philip Atkinson

 

The progress in the field of data storage has gone amazingly far in just a decade. Younger users these days have no idea what a floppy disk looks like and how to use it. Neither do they know how unreliable these little plastic squares were and how often they failed in the most inappropriate moments - after spending a couple of minutes lying on a speaker, after a long subway ride or any encounter with a strong magnetic field. This was the time when we worried more about getting our information from A to B than speed, capacity and ease of use.

Today, the abundance of high-speed and spacious portable media of all kinds - and, first and foremost, flash cards - in an average household increases the chances of data loss by a weighty factor. These troubles most often happen to flash cards that are actively used, mostly the ones in digital cameras.

The data on these cards are often deleted and rewritten; the cards themselves can be pulled out while the camera is still on and can be used with various card readers on various computers. All these factors increase the odds of damaging your photos and videos - seemingly beyond recovery. However, the great thing about today's file systems is that files are never physically deleted (but only marked as deleted) and there is always a good chance to get your photos back quickly with the help of specialized photo recovery tools, given that no new files have been written into the same area of your memory card.

If you face data loss problems from time to time or just want to be protected from such accidents in the future, you should check out one of such tools - for instance, at Recover Deleted Files and Photos Software.

This compact application is so simple and easy to use that even a child or a complete rookie can restore lost photos from any media in seconds. Now you won't have to look for a specialized data recovery service when you are on a tropical island (given that the odds of finding such a service in a remote location are close to nil) and face a data corruption problem. Just use your laptop or a computer in your hotel's lobby to quickly and painlessly recover what you thought was lost. This handy application is always with you and will help you restore photos with a minimum of efforts and expenses, so it's wise to have it with you whenever you go on a flash drive or a CD. The software meticulously analyzes the structure of your memory card and detects segments that have been marked as deleted or corrupted. Once the analysis process is complete, the application attempts to recover as much as it can - and succeeds in the majority of cases. There is hardly an easier way to recover lost files, restore deleted photos and fix flash cards! As mentioned before, the software makes no distinction between the types of media you are working with - it works with portable hard drives, USB drives, flash memory cards of all formats and sizes with equal efficiency.

If looking for an ultimate remedy for the problem of recovering deleted photos and files from portable media - and specifically camera memory cards - make sure to check out Recover Deleted Files and Photos Software. It has everything you need to face this problem with a relaxed grin!

Easy Digital Camera Buying Guide

By JR Lang

 When buying a digital camera there are some important features to consider and understanding these features will enable the consumer to buy the right camera that suits their needs and provide the education necessary to make an informed choice.

Important Features of a Digital Camera

Megapixels and Resolution - Basically the more megapixels the camera has the better and sharper the resolution of the images. If you intend to only email pictures or view them on your computer then any resolution is fine.

But, with a higher resolution you have the flexibility to print better quality pictures as well as print them in larger sizes with better resolution and perform other editing functions such as cropping and printing. Most cameras offer a resolution of at least 5 megapixels, which is enough to make a sharp 11-by-14 print.

Camera Size, Weight, and Design - Some cameras weigh as little as 4.2 ounces and while the pocket size camera may be convient there are some there are some important considerations when deciding on the size of the camera you purchase. First, the smaller the camera the tinier the dial and buttons that makes changing settings a hassle and so it affects user friendliness when taking pictures. Second, many smaller digital cameras do not have any manual settings.

LCD and Viewfinder - All digital cameras have an LCD screen; they vary in size from 1.8 to 3.5 inches. The smaller size limits your ability to review just-taken images on the camera. A good LCD is essential for knowing whether you got the shot you wanted, and can usually give you an indication of whether it was properly exposed.

Zoom Lens - This is a very important feature to consider.

Optical Zoom - The best option is to buy a digital camera with Optical Zoom. The optical zoom feature actually utilizes the movement of the lens. Optical zoom ratings range from 3X to 20X and the higher optical zoom ratings give much better image quality.

Optical zoom gives you all the benefits of the camera's maximum resolution, combined with the ability to focus in tight on faraway shots and scenes. An optical zoom is more important than resolution because it means you won't have to magnify your subject and then use software to crop the image and discard some of the resolution as a result.

Digital Zoom - The Digital Zoom lens only captures pixels and magnifies those and so it produces inferior photos, always go with Optical Zoom.

Tip: Ignore digital zoom in the Optical Zoom rating. While most digital cameras offer at least a 3X optical zoom and up to 20X, some vendors tout a high total zoom that includes digital zoom, and is not the true Optical Zoom rating.

Image Stabilization - Image stabilization is important because without it you need a steady hand or a tripod to avoid blurry pictures at extreme telephoto lengths. More advanced digital cameras, tend to employ one of two image stabilization methods. Optical image stabilization, in which an element in the lens adjusts to compensate for movement and sensor movement, in which the camera's sensor moves in order to compensate for the shaking.

Manual Focus vs. Point and Shoot Capability - Manual focus setting capability is important for getting certain shots. Often times this allows for adjusting the digital camera's settings to fit specific shooting situations and gives a lot more control and usability for the picture taker. The lower-end cameras do not offer manual focusing but instead offer a point and shoot capability or allow only stepped focusing, which forces you to choose from a few preset distances.

Exposure settings

Automatic Mode - All digital cameras let you shoot in fully automatic mode--just press the shutter release and you get a picture.

Aperture and Shutter Priority Modes - Adjusts the size of the lens opening or how long the shutter stays open, and the digital camera automatically controls the other variables to give you the proper exposure.

Facial recognition is a great feature offered by many point-and-shoot cameras and actually detects people's faces and adjusts the shutter for optimal images.

Memory/Storage - All digital cameras come with a "starter" memory card, usually that is 16MB in size. The starter memory card for a typical 5 megapixel digital camera set to its highest resolution can store six to eight pictures. The memory card feature is not so important because you can and will want to buy another one in order to have the optimal storage capability and convenience of not having to transfer the few pictures taken to make room for more. Several models and sizes of memory cards are available for purchase.

Batteries - Digital cameras batteries vary. Some cameras use AA's, either non-rechargeable or rechargeable, nickel metal hydride, high-capacity disposable CRV3s or proprietary rechargeable batteries.

Tip: Since digital cameras use a lot of battery juice disposable batteries can cost big in the long run. Using rechargeable batteries can save a lot of money. Many cameras allow the use of both so in the event the rechargeable is charging you can pop in some AA's.

User Friendly Controls and Menus - Consider the accessibility of buttons and menu options while holding the camera and taking pictures. Too many buttons or menu functions just confuses and can make it a hassle to use the camera and so affects the digital camera's user friendliness.
