Digital Camera

If you are in the market to purchase a digital camera, you have surely seen several different types of cameras. It isnt exactly clear what the differences between the types are, and it can be confusing trying to choose the digital camera thats right for you. In this article, we wil discuss the different types of cameras so that you can better understand what to look for in purchasing a digital camera.

Point and Shoot Digital Cameras

Most consumer cameras on the market today fall into the category of Point and Shoot digital cameras. These cameras usually provide resolutions of between 2 and 4 megapixels (million pixels). These cameras are the digital version of your typical 35mm consumer camera.

A point and shoot digital camera is designed to do just that - take snapshots. They provide limited flexability with options, although many newer models have some limited options for special effects. The image quality from a point and shoot digital camera is generally good enough for common uses, such as auction photos, and even 4 X 6 prints.

If you just want a standard, entry level digital camera for family snapshots and auction photos, then a point and shoot digital camera is a budget conscious choice.

Semi Professional Digital Cameras

A semi professional digital camera is a more advanced version of a point and shoot digital camera. Typicaly, these cameras provide resolutions between 5 and 6 megapixels (million pixels). They also often offer the user additional settings and greater control over the camera. The image quality of these cameras is good enough to produce clear prints up to about 8 x 10.

A semi professional digital camera may be the best option for you if you seek greater creative control than you can get with a point and shoot model. The increased flexability does come with a price. Most semi professional models are priced much higher than point and shoot models.

Digital SLR Cameras

If you are a serious or professional photographer, no less than a Digital SLR model will do. SLR stands for Single Lens Reflex. Digital SLR cameras are very similar in operation to their 35 mm SLR countereparts. Also, many camera companies (such as Cannon and Nikon) have built their digital SLR models to be compatible with 35 mm SLR lenses. This is a great benefit to professional photographers who can select a model that is compatible with their existing lenses.

Digital SLR cameras provide an amazing ammount of creative control over the camera and the resuting images. Also, these cameras provide resolutions over 6 Megapixels and can produce prints of poster size without noticable pixelazation.

A Digital SLR camera (without lenses) is a pricey investment indeed. Currently, you can expect to spend $1500 or more on the camera alone. Accessories and lenses cost extra.

Digital cameras have really taken off in popularity in recent years. It’s not uncommon anymore to see several people at an event with a digital camera. Here are some things to keep in mind when getting your digital camera prints converted into keepsakes.

Digital Camera Print - Where should you go?

Owning your own photo quality printer is definitely the fastest option. There are even people who take a small portable inkjet printer with them and make prints on the road.

Is it cheaper to print you own Digital Camera Print?

The large chains have jumped into this fray in a BIG way. Wal-Mart, Blacks, Business Depot, and many others. With all this competition comes low pricing. A typical 4×6 print from a big chain is cheaper than the retail cost of the do-it-yourself paper that the same chain sells in their photography center. And at home you still have to pay for the ink!

Keep the following in mind…

Low digital print price. All the major players have priced their 4×6 size very competitively. The larger sizes though, like 5×7 or 8×10, are usually higher in cost than what you can do at home.

Digital Photo Drop Off. Can you upload your digital pictures to the photo print company via the internet which is very convenient or do you have to deliver them on a CD?

Photo Print Delivery. Does your photo lab let you pick them up in the store, or do you have to wait for the post office or a courier? Picking them up at the store should be a no-cost option. If you can pick them up, make sure the location easy to get in and out of.

How fast can you get your digital photos? One photo lab has a reputation of having most orders ready in one business day. Another is a bit cheaper, but takes a week.

Digital Photo Quality. You may have to talk to relatives, friends, and co-workers about this one. Find others who have already tried various printers. One photo lab’s web site states that they will not print a picture with too low a resolution (nothing under 150 DPI allowed). This can be inconvenient, but assures you of a quality print.

Doing your homework ahead of time can ensure that you will get the best digital prints and the best prices so that you get maximum enjoyment out of your digital camera.

It seems for every year that goes by digital camera manufacturers are adding one more Megapixel (Mp) to their cameras. Could it be true that an existing 7 megapixel camera that’s on the market now had an equivalent model of 6 megapixels last year and 5 megapixels the year before that? Next year, will you see the same camera in an 8 megapixel version? Where will we be in another 10 years time?

But do we need the latest 8, 10 or even 12 megapixel camera? Well I have two answers for that question:

Yes, a.) You’re a professional photographer and often have to produce very large high quality prints. b.) If you love to have the latest and most up-to-date gadgets and technology, and are quite happy to spend the extra money to get it, and a little extra more to store those larger files.

No, because the biggest photo that I’ll print will be A4 or 10×8 and a 5 megapixel camera is more than capable of producing a quality photo at that size.

Let’s assume you’re not a professional, because if you were you wouldn’t need to read this article in the first place. So how many megapixels should you go for?
My short answer would be anything between 4 and 6 megapixels for an amateur who isn’t going to print much larger than A4.

Megapixels and Print Sizes
2Mp - Perhaps you have a camera on your phone. You wouldn’t want to get prints larger than 6×4.
3Mp - Will give you great 6×4 prints and good quality 7×5 prints too.
4Mp - Will give excellent 6×4 prints, great 7×5 prints, good quality 9×6 prints and passable 10×8 or A4 prints.
5Mp - Excellent 7×5 prints, great 9×6 prints, and good quality 10×8 or A4 prints. If your printer is capable of printing edge-to-edge photos then 5Mp will be your starting point.
6Mp - Excellent 10×8 or A4 prints, quality 15×10 prints and good prints up to A3.
7Mp - 8Mp - You must be a very keen on photography and looking for the best of kit.

Remember, the more pixels in your picture, the more storage space you’ll require and depending on the chip inside the camera it may take longer to process and save your files. This lag whist the camera is processing and saving the picture can be quite annoying if you like taking quick snaps. Some budget brands suffer badly from this.

To summarise, I recommend you stick with a quality brand and go for somewhere between 4 and 6 megapixels.

The world is going digital and people are crazy bout the hi-tech gadgets available in the market. But significantly paving the way is one of the hottest consumer products of the 21st century - the digital camera. Most people want to capture and store their precious moment forever in a form of pictures. And photography plays an important role in this business.

Digital photography has evolved over the past few years into a highly affordable luxury that some could not be without and cannot afford to loose it. If you are new to the world of digital cameras, let Office Shop Direct be your guide to their large array of product specifications.

Price ranges are a very big consideration and are mainly based on high-end specifications such as resolution, compression and zoom options. Cutting corners on some of these details will save you in the long run, but you should be sure what you are missing out on before you make that decision.

Important Items to Keep in Mind about Digital Camera Technology:

Interpolation is a method in which a camera will fill in the color holes in the pixels of a picture by estimating color blends. While this can improve resolution, it will also reduce the sharpness and contrast of a picture. Never get a camera that is low in resolution but high in interpolation if you want sharp bright pictures.

Compression routines are the way the picture is stored digitally. Some companies maintain their own proprietary compression method, and this can make sharing images difficult. JPEG is the standard, but also as with most standards can have less clarity in a picture. Consider cameras that also offer the ability to print off images at no compression for best results.

SLR is short for single-lens reflex viewfinder. Many cameras have two views: that which the user sees to set up the shot, and that which the camera sees. If you have an SLR camera both what you see and what the camera shoots are lined up as one, and not slightly off on a different angle.

Having an amazing photo shot is easy; following the above mentioned important tips will surely give you an exceptional picture. Capture your best moment with best digital camera and quality printing application.

Digital cameras are basically the same as film cameras in their handling. They both have a lens to focus the specific image, a shutter to let light inside the camera, and an aperture to control the amount of light which enters the camera.

The differences between digital and traditional photography happen to be after the light enters the camera. A traditional camera captures the images on film, while a digital camera captures the image on an image sensor.

Image sensors are electronic devices made up of an array of electrodes (or photosites) which calculate light intensity. The most universally recognized type of image sensor for digital cameras is the CCD (Charge-Coupled Device) although others such as CMOS and Foveon are sometimes used.

The number of photosites in the image sensor gives the digital camera its megapixel (millions of pixels) rating. Each photosite corresponds to a pixel in the final image, so a camera which is rated at six megapixels, for example, has an image sensor which is 3008 pixels wide by 2000 pixels high.

When light hits the image sensor it is converted into electrical signals which are built-up and fed to an analog-to-digital (A/D) converter. The A/D converter changes the electrical signal into binary numbers which are processed by a computer housed in the camera body. Once the numbers have been harvested the resulting image is stored on a memory card.

Photosites can only measure intensity of light — not color. In order to produce a colour image, each photosite must be covered with a colored filter which can be red, blue, or green. These are the three primary colors which can be combined to produce any other colour including white.

The colored filters are arranged in a grid so that there are twice as many green filters as there are red or blue. This is because the human eye is twice as sensitive to green light. Filters are arranged in a pattern called the Bayer pattern - one row of red, green, red, green (etc.), and the next row of blue, green, blue, green (etc).

Since each photosite can only be covered with one coloured filter, computer processing is necessary to produce a full colored image. This is done by analyzing a certain pixel and its immediate neighbors and producing a composite colour from these calculations. For example, if a bright red pixel is surrounded by bright green and bright blue pixels, the bright red pixel must undeniably be white, because white is the combination of red, blue, and green. This process is called demosaicing.

After demosaicing the image is adjusted according to the settings on your camera. Most cameras have settings for brightness, contrast, and colour saturation. After these adjustments are made some cameras may also apply a sharpening algorithm to make the image clearer.

The final step before saving the image on the memory card is to compress it. Most cameras use JPEG as a compression format. This reduces the size of the file by eliminating excess data. This information cannot be recovered, so JPEG is called a ‘lossy’ format.

Several cameras have the ability to save uncompressed images as TIFF files or raw data. Raw data is the original photosite data even before demosaicing. It can be transferred to a computer for processing with special software that will perform all of the processing functions of the camera but with much greater control.
