Digital Camera Ling

Posted on by

Every advance in technology creates new terms, acronyms and definitions. The digital camera revolution is no different. When shopping for your first digital camera, it is always good to know the lingo. Saves you from that stupid feeling one often gets when speaking with sales people. I hope this glossary helps.

Aperture

The size of the lens opening, which controls how much light, passes through the lens. Aperture is measured in f-stops. A higher number equals a smaller amount of light. Most digital
cameras allow manual aperture settings.

Auto Focus

This feature automatically focuses your picture at the touch of a button. By pressing slightly on the shutter release, the auto focus feature of the camera is activated.

CCD

The CCD (charged couple device) is the electronic imaging device that forms your picture in the camera. In other words, it is the electronic version of film for a digital camera. The higher pixel counts in the CCD, the more detailed image.

Digital Image Stabilization

A process by which blurring in pictures caused by camera movement is minimized and possibly eliminated.

Digital Zoom

A function which can enlarge a picture by increasing the size of the pixels. This often results in some fuzziness of the subject.

DPI

DPI stands for dots per inch. It also refers to the resolutions of the picture. The higher the DPI, the sharper the picture.

F-Stop

F-stop is the number assigned to a particular size opening on the aperture. The higher the number, the small the opening. Larger numbers admit less light; smaller numbers admit more light.

File Format

This is the way digital pictures are stored. The most common formats are jpeg, GIF, tiff and RAW. The format being used appears at the end of the file name.

Gigabyte

A gigabyte (GB) is a measure of data storage capacity. It is approximately on billion bytes.

LCD Screen

The liquid crystal display (LCD) screen is used to set and view digital pictures immediately after taking them.

Macro

A feature that allows a camera to take extreme close-ups of the subject.

Megabyte

A megabyte (MB) is a measure of data storage capacity. It is approximately one million bytes.

Megapixel

A megapixel is a unit of measurement in a digital picture. A megapixel equals on million pixels. The higher the megapixel total the higher the picture resolution.

Memory Card / Media Card

A memory card is a small electronic device that stores images. Storage capacities range from 16 MB to 4 GB. It is capable of storing still images or video.

Noise

Graininess in an image, caused by too little light or a defect in the electrical signal generated during the image capture process.

Optical Zoom

A type of zoom on a digital camera that enlarges the subject by the use of glass lenses. It is the most important type of zoom on a digital camera.

Recycling Time

This is the amount of time it takes for a digital camera to ready itself for the next shot.

Red Eye Reduction/Red Eye Removal

This is a process by which red eye coloring is reduced or eliminated. Red eye is more common in low light situations when the pupils are wide open. Light reflecting off the back of the eye causes it.

Scene Modes />
Scene modes are pre-set programs in a digital camera that adjusts the camera to specific picture taking situations.

USB Connectivity

A popular way of connecting all sorts of devices such as a digital camera to computers. USB connectivity is used to download your photos from the camera to the computer.

Things To Consider In Buying A Digital Camera

Posted on by

Today, digital cameras come in a number of sizes and shapes. Each model offers it owner a set of different features for various conditions. It is amazing that all of these cameras are still easy enough for a child to work with.

Around the world the digital camera has become an everyday object in many homes. The camera has been added to other gadgets such as the cell phone. And despite this, the camera still works pretty well when taking shots. You can add memory to your digital camera no matter what gadget it is attached to. In fact if you add enough memory you are able to make video clips.

The brands that you find offering digital cameras are numerous. Traditional camera manufacturers like Canon, Nikon, Olympus and Kodak and Panasonic, Sony and Casio have also joined in.

Basic Features to consider

No matter what brand name the camera comes from there are a number of features that should be looked at while shopping around. One such item would be the megapixel.

Megapixel means millions of pixels and the term pixel is the amount of dots that make an image. This is used to judge the quality of the camera. If a camera has a three megapixel resolution then it would be considered of lower quality than a camera with five megapixel resolution.

A picture that came from a five megapixel resolution can be enlarged with more clarity than the three megapixel camera. However the higher the megapixel resolution the more memory used.

Another basic feature to check out is the zoom feature. There are basically two kinds on the current market. There is the optical zoom setting that can be found in cameras with no permanent lens so a person can just zoom in on their subject and click. The other is the digital zoom feature which has the same value as a software program for editing your pictures. Many cameras offer both features but the zoom feature is the one that is recommended when trying to make a decision on a camera.

On all digital cameras there is usually a LCD screen. This is one difference between traditional cameras and the digital camera. This enables a person to look at the shot as it would appear in the end rather than peering into a small aperture.

What to look for

The camera has slots where the memory sticks are inserted. It is important to think about memory because a camera which requires more memory may end up being more expensive in the end

Most digital cameras come with rechargeable batteries and some have a charger as well if they don’t you will have to take that into consideration when totaling the costs of your new camera.

Some cameras allow the pictures to be downloaded into your camera using a USB port and then editing or printing out the end result.

What To Look For In A Great SLR Digital Camera

Posted on by

The technology of photography has continuously evolved and improved since the turn of the 20th century. The demand for traditional camera that used films has long been decreased. With the current technology, digital cameras have been introduced. People who love capturing every single moment are indeed amazed by the digital cameras. This is because of the ease that the camera offers for those who are not really into photography. Technology isn’t only for those who are not into photography; it also offers something to those who consider photography as a profession and science. Professional photographers find their job and profession easier to manage and do and at the same time more relaxing with an SLR Digital Camera.

A digital single-lens reflex camera (digital SLR or DSLR) is a kind of digital camera with an automatic mirror system. The automatic mirror system applies the theory of prentaprism wherein light is directed from the lens through the use of the viewfinder. Its design is completely different from an ordinary digital camera. An ordinary digital camera exposes the sensor directly to the light which is projected by the lens whereas as DSLR uses its mirror arrangement to prohibit the scene from being viewed on the LCD. Now, new models of DSLR have a live preview feature where LCD can be used as viewfinder.

If you are contemplating of buying an SLR Digital Camera, you have to take note of its features and operation system. Be aware of its differences from a standard one. Be sure to distinguish which one is good and which is not.

A good SLR Digital Camera has complete features including the unusual ones. Check if the SLR Digital Camera you are buying has the ability to record the ultraviolet spectra of light. Check if the camera has a mode dial feature. It is used to access the camera settings. A good one should also have an automatic scene-mode feature.

Check the focal length and sensor size of the camera’s lens. A good SLR Digital Camera has a big sensor. This gives a bigger angle view depending on the focal length. Thus, a good SLR digital camera has a more than average focal length. This type can be more expensive but you are assured of the greater quality of the image.

A good SLR Digital Camera should have depth of field control. It is possible to limit the depth of field. It is not good if the photographer cannot adjust or limit the depth of field because he can’t take pictures where the background is sharpened. A good SLR Digital Camera should have wide lens. The wider the lens, the greater the depth of field can be and it is easier for the photographer to adjust it to the limit and depth he wants.

SLR Digital Cameras are generally big in size, greater in cost and has lack of video mode. But camera manufacturers have started releasing cameras better than usual. Compared to the first releases of SLR Digital Cameras, newly released SLR Digital Cameras are now smaller, although still larger than the ordinary digital camera. A good SLR Digital Camera is a little smaller than the usual and has a better video mode than the standard SLR Digital Camera.

Due to SLR mirror mechanism, it is normal for the camera to create some noise when being used. But manufacturers have it improved by minimizing the noise produced in its operation. A good SLR Digital Camera is the one which is more quiet than the usual.

Changing of lens is possible for an SLR digital camera. Thus, contamination caused by dust particles when changing can’t
be avoided. It is therefore advised that you look SLR Digital Camera which has the ability to clean the dust from its camera sensor.

A good SLR Digital Camera also has a 3 Asic (application specific integrated circuit). It is a digital engine that supports the camera to perform mask generation. This is for the purpose of increasing the speed accuracy and sharpness of the photo. It is best when the camera you are buying has an auto focus system design. This is recommended for those who love taking moving images. Without the auto focus, it is very difficult to get the perfect angle. It should also have the white balance system increase and maximize the output of the photo.

What makes the SLR Digital Camera good is that it is user friendly. With all the complicated features mentioned above, one will find in the end that it’s simple. With the programmed mechanism and operation, it is easy for the photographer to just find the image, snap and print it.

Indeed, technology is quite amazing. This can be proven in digital cameras. All you need to do is find one that suits your style, your profession and your budget. You’ll make one good photographer with a good SLR Digital Camera on your hands.

Kodak CX7300 Digital Camera

Posted on by

Quality digital cameras are becoming affordable for just about everyone these days. Kodak’s entry into the low cost end of the market is their CX7300 3.2 mega pixel model. You just may be surprised at what a terrific value it is. Please read on.

As recently as two years ago, if you were shopping for a 3.0 mega pixel or greater camera, you would have paid approximately $249. for one. Today, prices have tumbled and it isn’t uncommon to find cameras in this category going for $150 or less. Recents sale prices I have observed have brought this price down further with one retailer selling the Kodak CX7300 for just under $100.

As you may know a 3.0 meg camera is ideal if you are taking pictures to post online. Anything greater isn’t necessary, so there is no need to expend the extra bucks for a 5.0, 6.0, or even 7.0 meg camera.

This particular Kodak model is no bare bones model either. Top features include:

3.2 million pixels

3x digital zoom

1.6" color display

Red eye reduction

Self timer

Color modes

Multiple scene modes

Movie mode

16 MB internal memory

Easy Share software

The CX7300 is easy to use and picture quality is very good. Kodak also markets this model camera as a C300, so shop around and see what your retailer is offering.

Digital Cameras: Another Kickin’ New Feature: Video Capture

Posted on by

Digital cameras have come a long ways in the past few years. They are now more affordable and feature rich than ever. A comprehensive list of features and advice for choosing a digital camera is beyond the scope of this article, but this article will highlight one of the most popular features, video capture capability.

With a video capture feature on your camera, you can take low to medium quality video footage using your digital camera. All cameras with video capture are not created equal, though. Here are some things to check on before buying a camera with video capture:

1 – Sound

Does the camera support sound? If so, does it capture it through a built in microphone, or does it have an input for you to plug in an external microphone?

2- Video Quality

There are two main factors that determine video quality – resolution and frames per second. The higher the resolution, and the higher the number of frames per second, the higher quality the video.

3- Video format

What format is the video in? Ideally, it will be in a standard, easy to edit format, such as MPEG. Some cameras use proprietary video formats, which means that you can’t edit your videos with most editors. Windows Movie Maker, which comes free with Windows, is a great editor to use for most generic video formats.

4- Video length

Some cameras limit the length of video clips you can take, often to 30 seconds. This can be a great aggravation. The better cameras allow you to take as long of a video clip as your camera’s memory can hold. Of course, you can add a larger memory stick to take a longer video clip. You can now get memory sticks up to 2 GB or larger.

5- Zoom

On most digital cameras, you can use the zoom when taking video footage. However, you can generally only use your optical zoom, not your digital zoom.

Tips On Digital Camera Printers

Posted on by

OK, so you’ve taken tons of pictures, and unless you plan on looking at them forever on your PC you’ll eventually will want to print them out. I know you’re asking "can’t I just take it to the local one hour photo store?" The answer to that question is an absolute "Yes!" But there are other options should you desire.

One of those options is to get yourself a digital camera printer. And just like every other product that I cover on this web-site, you are bound to have a multitude of choices at your local electronics store. Some of the more common brands include HP, Cannon, and Epson. I also personally believe that they are some of the better printers as well.

You need to know that digital camera printers come in three types; 4-color printers, 6-color printers, and 8-color printers. As you may have guessed already the high the number of colors, the higher quality your prints will turn out! Not surprisingly, the higher the number the higher the price usually goes.

The next thing you need to understand is the method by that digital camera printer uses to create the photos. Right now on the market there are two methods, ink-jet, and thermal. Ink-jet is used for a variety of purposes in general printing. So if you’re a novice photographer then this is probably the way to go. However, if you want something that is more professional then thermal is the choice. The largest difference between the two options is that thermal adds waterproof coat to the image which ensures that the photos will not fade for a very long time.

The final think that you need to know about digital camera printers is the quality of paper that you will be using. This is where I say that even for a novice photographer, you really need to invest in some good quality paper. Get some think glossy paper that you can use. You can buy this at just about any office store like an Office Depot or Staples.

Finally printers in general can be sometimes tough to work with. I invite you to play around with your digital camera printer to educate yourself as to how the thing works. Breakdowns are common I’m afraid, so make sure that you get your printer from a reputable store and even think about getting yourself an extended warranty if the printer doesn’t already have a good standard warranty.

My Secrets of Choosing a Digital Camera

Posted on by

When shopping for a digital camera, there are a few things that you should consider. It is not only to get the cheapest digital camera or the model with the most functions. Check out my list and than go and find the right camera model for your special purposes.

Size
Small is beautiful. Todays digital cameras are sometimes so small, that they fit into the breast pocket of your shirt easily and are still fully featured so you get the most out of the camera in almost every situation. Just imagine taking a picture of a wonderful sunrise when your are on your morning run or the happy smile of your kids when you pick them up after school. With a small digital camera you don’t have to lug around heavy equipment, you are always ready to take the picture of your life.
But too small could be a nightmare for someone with large hands or big fingers. In this case it is not practical and the fingers could cover the lens, the internal flash or could not work the tiny buttons to select the diverse functions, a modern digital camera offers.

A larger, heavier digital camera is useful when you want to do more serious work. Think about taking pictures where the internal flash is disabled and you work with longer shutter speeds. A heavier camera is easier to hold steady and it can better compensate the tine movement when you press the shutter button.

System
there are many different kinds of cameras on the markiet today. The consumer has the choice between an ever increasing number of brands, but mainly his decision is based on what what he wants to use the camera for and what his past experiences with photography are.

Viewfinder cameras
this is the most simple system on the market. The viewfinder is located in the upper left corner of the camera (seen from the rear) and presents a picture that is slightly offset to what the camera really sees. When you are very close to an object, the difference in view can be dramatic.
This type of digital camera works very good for snapshots as well as for most photographic needs of the average person. Disadvadvantages are the fixed lenses, the lack of influence you can take on the picture (e.g. sharpness, focus, light).

Some more advanced models also use the small LCD monitor as a viewfinder. The advantage here is that the picture you see on the screen is the same that you will take with your camera. You have good control of what you will put into your picture. Disadvantage witht his type of display is that you cannot preview the pictures in a brightly lit environment. Taking pictures in brought daylight is sometimes difficult as you try to hold the camera stready and also shade the lcd.

Bridge cameras
this type of camera is more heavyset than the usual compact digital camera. Usually it features a fixed lens with a good zoom factor. Ranging from wide angle to telephoto, you can cover most photographic challenges with these models. They offer a trough the lens view finder, which gives you a correct impression of the photo you are going to take, regardles of focus length. The picture is projected on the CCD chip in the camera and projected on a small monitor that is either inside the camera positioned like on traditional cameras or on the back panel of the camera body.
These cameras are usually more capable of changing photographic parameters and are used by people who want to do more than the occasional snapshot.

Digital SLR (Single Lens Reflex)
this is the most advanced type of digital camera on the market today. It works very similar to traditional SLR cameras, but using the digital process instead of film.You can choose
different lenses for every possible purpose. Whether it is a wide angle lens for landscape photography or a small telephoto lens for doing portraits or close-up work. The lenses are interchangebel and you sometimes even get compatible lenses from thrid party manufactures that are of similar quality, but lower in price. The picture is reflected into the viewfinder via a mirror (this is why its called reflex). When you release the shutter to take the picture, the mirror is moved away, the shutter curtains open and the light is directly sent to the CCD chip. A small LCD screen on the back panel of the camera is used for doing a first check on picture quality and for setting the different features and options of the camera. Digital SLR cameras are usually used by professional photographers and high level enthusiasts.

Memory – Bigger Is Better
The advantage of digital cameras compared to traditional ones is that you can shoot as many pictures as the memory chip allows. Pics that turned out to be low quality can easily be discarded and again you have room on your memory card to take new pictures. As advantageous as it is, this circumstance leads to taking more pictures than with traditional cameras and as the resolution of the digital cameras increases from year to year, the need for memory increases. Therefore it may be useful to exchange the memory card that came with the camera with a bigger one or having a spare one when going on a longer trip. Below table lists the aproximate number of photos that fit on a 128 MB memory card when using the jpg-format:

Resolution Quality_____Best_____Good_____Standard
6 mpixel – 3008x2000_____34_______70_________117
4mpixel – 2400x1600______51_______96_________161
1.5 mpixel – 1536x1024___106______173_________271

The above quality rating is based on the compression factor of the jpg format (higher compression results in smaller files, but in lower picture quality).

Now, I wish you good luck with shopping for a new digital camera.

Comparing Digital Camera Features

Posted on by

More people are able to afford digital cameras because their prices are falling but the number of characteristics is rising so it is important to be able to compare digital camera features.

The first step in being able to compare digital camera features is to decide what you want to get out of your camera. If you compare digital camera prices you will see that for shooting family snapshots you can get a good basic digital camera for under $400, while a professional model is over $2,000. When you compare digital camera features you need to know the extent of the use you are going to get out of it.

It is essential when you compare digital camera options to understand the issues of image resolution, which is measured in megapixels. Basically, the more megapixels, the higher the resolutions of the final image but you definitely need to compare digital camera images with your actual requirements. This is best done if you compare digital camera resolution with the size of the images that you want to print and you will find that a 1-mg camera can create a 3-by-5-inch (7.5 by 13 cm) photo-quality print; a 2-mg camera will make a 5-by-7-inch (13 by 18 cm) print; a 3-mg camera will make an 8-by-10-inch (20 by 25 cm) print, and a 6-mg camera will make a 9-by-13-inch (23 by 33 cm) print.

One of the other points to consider when you compare digital camera prices is to look at the complete package that is offered. Some included extras to look for when you compare digital camera packages are if the camera includes a cable for your computer and if it comes with image-editing software that works with your computer. If these are not included it is still possible for you to buy them separately but you need to allow for this when you compare digital camera prices. Another important point to consider when you compare digital camera options is to choose a camera with removable memory in addition to built-in memory.

All of the cameras that you are considering when you compare digital camera features should have an LCD screen for viewing pictures, a built-in flash, a timer, and a time/date stamp on even the most basic camera. You should also look to compare digital camera packages that have optical zoom, not digital, if you need a zoom capability and most midrange cameras should have high-quality optical zoom lenses but it is still worth checking to make sure.

Purchasing Digital Camera Batteries

Posted on by

The advent of digital technology has greatly changed the way consumers use products. Digital cameras are one product that has shifted behavior and production. Digital camera batteries vary by brand and model, and also by the type of battery.

There are literally dozens of digital camera brands. Before finding the right digital camera battery and adapter for your camera, you need to be sure of the brand and model digital camera you are using. Once you select the brand, there are numerous model numbers to choose from and these batteries are typically not compatible across model numbers. Manufacturers design a specific battery technology for each model that provides optimum functionality for that specific digital camera.

Digital camera batteries can vary greatly by price depending on the type of battery you purchase. Traditional alkaline batteries are far less expensive than newer technology batteries, but do not last as long and do not have as much power. In order to keep up with the fast pace of digital cameras, manufacturers have created Lithium batteries. Lithium batteries last up to 10 times longer than alkaline batteries, and therefore can take many more pictures. Though lithium batteries last so much longer, they weigh much less than alkaline batteries. For the convenience however, lithium batteries are much more expensive than alkaline batteries. Another inexpensive alternative to lithium batteries is oxy-nickel batteries. There are specifically designed for digital cameras and last up to four times longer than alkaline batteries.

There are lots of things to take into consideration when purchasing a digital camera, but batteries aren’t usually one of those things, though they should be. Batteries are one of the only supplies for a digital camera that will need to be bought on a regular basis. Unlike conventional cameras, you never need film for a digital camera. But if you want to store these photos without a computer, you will need memory cards that can store large files like the images taken with a digital camera.

Buying the best digital camera battery is the best way to get the most out of a digital camera. By buying quality batteries, you will be able to take more pictures without delays and also save money in the long run.
