Everything Digital Cameras

With the advent of digital camera technology, taking pictures has been more fun than ever. We don’t have to worry about paying for bad pictures at the photoshops and neither do we have to wait for long days to get our surprises(pictures) back. With digital cameras, taking pictures has become very easy and a fun thing to do. Take a shot, you like it, keep it otherwise delete it, that is as simple as it can be.

Most of us nowadays own a digital camera but we don’t really know how to take good pictures. By just observing some simple rules, one can make very nice photos with a camera. With digital cameras particularly, this is very easy as one can take more than one picture and keep the best of all.

The following can summarize a good composition:

First is the way one should hold the camera. A camera should be help in a way the hands does not block the view in the viewfinder or the live screen. Imagine your shot, have a clear picture of what you want out of your shot. Try to capture as much of your main subject and try to avoid the rest as much as possible. For a portrait, this means usually to fill the person or persons in the frame completely and avoid everything else. For a nature shot, frame nicely what you want inside the picture. Watch for the horizon, most pictures turn out to be out of level. Be careful with the way the camera is handled. Watch out where the light source e.g. the sun, light bulb etc. is. The camera should not be facing the light source otherwise the photos will turn out dark. The camera should always be facing back to the source while the subject should be facing the light source so he/she/it is properly illuminated for a clean visible picture. In case of light source into the camera, the pictures will be dark and the subject would be not visible. Watch out for the camera settings before taking a shot. In low light conditions, the shutter speed can be very slow so the camera should be held steady for quite some time. Use the flash light where necessary, though it can be very tricky but try multiple shots. Do not use a flash when the subject is against a white wall or a bright background. The reflection from the white wall or the bright background can cause the shutter speed to be faster, making the the subjects appearing very dark. Try using the flash with dark or no backgrounds.

These were some very basic tips for novices and beginners. Any questions or comments, welcome:)

There are so many models of digital cameras available in today’s market, that it becomes a rather difficult task to pick the best buy among so many options. Perhaps a few steps should be taken into consideration when choosing the right camera. Will the camera be for daily use, or just for special occasions like birthdays, family reunions, etc. Will the price of the camera make much difference on the pocket?

Assuming that price is not an issue, one should choose a well known major brand camera and if possible, go for the latest model and with the highest number of mega pixels available. The higher the mega pixels, the better the picture will be specially if there is an intention of having photo enlargements quite often. A good quality optical zoom lens will also make a big difference. Choose a camera which comes with a battery that holds a good charge, this way you can enjoy lots of picture taking without having to be worried when the battery charge will come down.

The range of features available make a digital camera very cost effective and more than likely you will be able to find the right camera suited to satisfy your needs.

If you enjoy printing enlargements of your photographs, you may want to pay close attention to the printing size and what is required in mega pixels for you to have good quality results. For you to have an idea of the amount of mega pixels required for most commonly used size of prints, refer to the chart below:

For photos 2×6 inches – 2 mega pixels

For photos 5×7 inches – 3 mega pixels

For photos 8×10 inches -7 mega pixels

For photos 11×14 inches – 14 mega pixels

For photos 16×28 inches – 28 mega pixels

For photos 20×30 inches – 54 megapixels

The handling and design also matters and the lightweight ones are much nicer to carry around. Choose a camera that is user-friendly and make sure that you have a good local technical assistance in case you may run into problems with it.

There are several advantages of having a digital camera instead of the old traditional film camera. First of all, there are no films to be purchased ever. You make take dozens, perhaps hundreds of photos and instantly delete the ones you don’t like, or that did not came well into focus and just keep the best ones. You may load them into your computer album, record them and you may view your favorite photos from you camera or from your television set. Some digital cameras also come with a recording device that allows you to record special events and replay them immediately after recording

Digital cameras take pictures that are stored in digital media. It is possible to select, save or delete photos without any cost whatsoever. The photos are usually stored in media cards into the hundreds, meaning that you can take as many pictures as you like before you run out of space. Also in most digital cameras, the user can view the pictures on the LCD screen, which will allow him to pick the best ones.

No wonder that digital cameras became so popular and accessible item to almost everyone. It became a must to have one nowadays and even cell phone cameras are getting better everyday with noticeable improvements in quality of picture taken. The earlier models of cell phone cameras were somewhat limited as far as picture quality is concerned comparing to the ones we find on today’s market. The mega pixels are increasing constantly and so the quality of the cameras. If a person needs to carry both at the same time, maybe a cell phone with a digital camera built in will be an interesting option to consider

If you have not bought yet a digital camera, maybe this the right time to do so, considering the manufactures are offering so many new models with new features at bargain prices. It is wise to compare the several models among different manufacturers and also the prices from traditional and online stores. Make sure you do your research right, and most likely you will find the digital camera you are looking for.

A digital camera captures images in a digital format, unlike a conventional camera, which captures images using a photographic film.

History:

Using a mosaic photosensor, Eugene F. Lally of the Jet Propulsion Laboratory first showed how still photos could be produced in a digital domain. An engineer at Eastman Kodak, Steve Sasson, used solid-state CCD chips to build a prototype digital camera having a resolution of 0.01 megapixel, and recorded black and white digital images to a magnetic cassette tape. With this prototype model, Steve took the first image in December of 1975 taking 23 seconds to capture it.

In 1988, Fuji DS-1P became the first digital camera that captured images as a computerized file. However, the camera never entered the U.S. market. In 1991, Kodak DCS-100 was the first commercially available digital camera, which used a 1.3 megapixel sensor. With the advancement of technology, modern digital cameras have become multifunctional and are now capable of capturing audio/video and still photographs.

Benefits:

Power:

Digital cameras consume a lot of power, which is supplied by powerful, small in size batteries. Batteries are broadly divided into two groups, namely, off-the-shelf and proprietary. Off-the-shelf batteries are like AA, CR2, CR-V3, AAA, and RCR-V3. They are lithium-ion (Li-Ion) or Nickel metal hydride (NiMH) batteries. Standard AA non-rechargeable alkaline batteries either do not work or work for only a very short time in most cameras.

Proprietary batteries are built as per the manufacturer`s custom specifications and are usually available as aftermarket replacement parts. Generally, lithium ion batteries are widely used as proprietary batteries for digital cameras.
