Nikon Digital Camera: Digital Slr Cameras

January 25th, 2009, author : jve07

Nikon is a camera brand, best known for producing SLR camera. As with the boom of digital cameras all over the world, Nikon joined the bandwagon by producing what they make best, thus the new era of the Nikon digital camera was born – digital SLR.

One of the best in DSLR, the Nikon digital camera called Nikon D70 is 6-mega pixel Nikon digital camera. Coated with polycarbonate over its stainless steel chassis, this Nikon digital camera is furnished with a 50mm AF Nikkor lens that can combine with an 18-70mm kit lens and still be portable enough to be carried around. It has a 200-1600 ISO effective speed range, great for taking pictures both in the shade and under the sun. and why won’t it be?! With its three frames per second continuous shooting rate and its 1/8000 second shutter speed, taking pictures is as easy as clicking away and having fun. this Nikon digital camera is supported with a Flash card.

Another SLR from Nikon is the Nikon Coolpix 8800. An 8-mega pixel Nikon digital camera, the Coolpix 8800 has a compact body. Furnished with a 1.8 inch flip-out and swivel LCD, this baby is surely first rate SLR. This Nikon digital camera features an image stabilizer system to reduce camera shakes particularly on long shots since this gadget can zoom up to 10x (optical zoom) and can focus to up to 3cm in macro mode with its 35-350mm lens. Key controls are very user-friendly, with modes such as sensitivity, image size/quality and white balance – found directly with the mode dial. The image output quality is the middle name of this Nikon digital camera, with great detail rendition, color fidelity and saturation. a rather exceptional feature of the 8800 is the continuous shooting modes, where users can choose 1.2 or 2.3 frames per second. A bit bulky to carry around, the 8800 is perfect for shooting action and sports shots. The 8800 works with a Compact Flash card for storing up your images.

Underwater Digital Camera: Capturing Moments Underwater

January 15th, 2009, author : jve07

Memories are created just about anywhere. And when I say anywhere, I mean that memories are even created underwater – so the creation of underwater digital camera.

An underwater digital camera is not just used to capture underwater memories; some professional marine photographers also use underwater digital cameras in their business. Even marine biologists and scientists use underwater digital cameras to capture marine life and thus be able to study the life and properties of the marine life. But I think it is safe to assume that you, my reader, are neither a marine scientist nor a professional photographer. Like me, you are just some photo junkie who wants to capture underwater moments and just cant figure out how without ruining your cameras.

Please listen to me when I say that even waterproof cameras cannot withstand underwater photography. To be waterproof is to resist the water in certain levels, submerging in under the water to get the perfect shot is like throwing it out of the window expecting a pick-up truck to pass by and run over it.

Now if you’re really serious about using an underwater digital camera to capture those wacky and funny moments underwater, I suggest that you buy specialty cameras.

There are rarely underwater digital cameras, as cameras are electronic and cannot withstand water and water pressure. The closest electronics has ever got to producing underwater digital cameras are producing underwater casings for digital cameras. These casing will turn your conventional digital camera into an underwater digital camera.

Digital Camera: The Future Of Cameras

January 3rd, 2009, author : jve07

Basically a digital camera is a deice use to capture pictures without the use of films. Unlike the conventional camera, the digital camera does not rely on mechanical and chemical processes. It has a built in computer and records the images it captures in an electronic form. Having and operating one does not even require the use of electricity.

Since the images that a digital camera captures is in electronic form, it is a language recognized by computers. This language is called pixels, tiny colored dots represented by ones and zeros that make up the picture that you just took. Just like any conventional cameras, a digital camera is furnished with a series of lenses that focus the light and creates the image that you want to capture. The difference here is then; a conventional camera focuses its light on a film while a digital camera focuses the light into a semiconductor device that electronically records the light. Remember the built in computer, it comes in here and breaks this information to digital data resulting to all the features of the digital camera.

Another feature of the digital camera is that it has a sensor that converts light into electrical charges. A charge coupled device or CCD is an image sensor that is found in a digital camera. While other low-end digital camera use complementary metal oxide semiconductor or CMOS as an image device, it can still become better and more famous in the future but most engineers are do not believe that it can replace the CCD for higher-end digital cameras.

A collection of tiny diodes, the CCD gathers electrons when they are struck by photons or the light particles. Each diode or photosite is sensitive to light, meaning that the brighter the light, the number of the electrons gathering will be larger

The price of a digital camera nowadays have been depreciating, one of the main reasons of this is because of the introduction of CMOS image sensors, this is because CMOS sensors are less expensive and are easier to manufacture than CCD sensors. A CCD and CMOS sensor works the same way at first, by converting the light electrical charges into photosites. Simply putting it, is to think that a digital camera works in such a way as thinking that the millions of tiny solar cells, each of which forms a part of the whole image. Both CCD and CMOS do this task using different methods.

When shopping for the best digital camera, take note of these key features.
