By awareness the function of megapixel in a digital camera, you will be able to buy the finest option at the cheapest rate. Even beginners will be able to opt a better camera.

Higher the megapixel count, better is photo-quality?

This is one of the most misunderstood impression about rating of digital camera and their photo excellence. Consider a mosaic of tiles, each megapixel is like a tile and a mosaic of these tiles make a picture clearer. That is all right, but it doesn’t mean that picture taken by a 10 or 12 or 50 megapixel camera will be more sharp than a 3 megapixel camera, because for most practical purposes, 3 megapixel quality is good enough. At the most you may require 6 – 8 megapixel for photo-quality as appears in magazines. Anything ahead of that isn’t of much use to a non-professional photographer.
One megapixel is like one tile. When a picture is taken, the CCD or CMOS sensor in the camera receives an array of such tiles to create an image. It then converts it to electrical signals which are processed to deliver a picture. An array of 2048*1536 generates a pixel count of 31,45,728 pixel which is amount to to 3.1 megapixel.

What affects the quality of pictures then?

The quality of the lens, the algorithms used to make the photo from raw data composed by the sensor and the focusing mechanism are some of the other factors that affect the final result.
It should also be considered, how large is the sensor in the camera. Consumer digital cameras have tiny image sensors. They are measured in microns. A micron is a millionth of a meter. Most sensors in consumer cameras are less than 10 microns. It is kept so so as to decrease the size of the camera so you can carry it in your pocket.

DSLR cameras have larger sensors. The main disadvantages of a smaller sensor is that it generate images with more noise than a large sensor. If you have to focus on a small area, it is difficult to do with a small sensor. Further, any shaking in handling the camera is blown up in a small sensor.

That means in right hand, with a appropriate sized sensor, a 6 MP camera is also good enough. In few scenarios a larger megapixel count may be useful, but for general purposes, it is not required.

In what scenario is a higher megapixel beneficial?

If you have to take the photograph of an airplane or a bird flying at a distance and you starting zooming with a digital camera, use digital zoom to reach it, the picture becomes granular. This is a typical defect of the digital zoom. In such a case, if you have a higher megapixel count, you won’t need the digital zoom.

Buy wisely choosing the appropriate megapixel rating you will be able to get a cheapest yet a better digital camera.

The Canon Power Shot SX230 HS 12MP Digital Camera may be a fine idea for anyone to have quality affordable digital photography. With the online sales now going on, this device should not cost more than about $210.

There are photographers out there who swear by other brands, but once they composed and shot any images with any Canon products, they may become converts. Take the Power Shot SX230 HS 12MP Digital Camera, for example. It exhibits the full range of Canon’s advanced photographic features.

For example, how many times have you used an optical zoom feature to get very close to a subject, only to find that you need a tripod or other hard surface to brace the camera against because of stability issues (telephoto feature enhances camera shake and makes it hard to retain focus). Canon’s Optical Image Stabilizer system helps you to home in on the subject and take the shot. It can do this because of its 14X optical zoom system and Canon’s advanced DIGIC4 Image Processor makes the entire process possible.

The SX230 is listed as a 12 MP digital camera, but it is really much more. Although it offers the traditional viewfinder – useful if you want to frame a scene – the SX230 also offers another feature that any photographer will love and that a moveable image screen. Most digital photography isn’t done through viewfinders. Instead, you hold the camera up and line up your shot through the 3-inch diagonal rear display and that’s when the true capabilities of the SX230 come into play.

If you want to do the traditional “point-and-shoot” picture, you can, but Canon has added some assistance for you. They have expanded the number of traditional camera/lighting/lens settings available for you on the rear thumbwheel to 32 (night, nature, portrait, landscape or you can choose auto), so it does make your shooting easier.

You can equip your SX230, which effectively shoots at 12.1MP and features a standard mechanical 4X zoom, as well as the 14X optical – both bonuses – especially on a camera with built-in 5-70 mm zoom lens, with up to 32 GB of SD memory so you can not only record single scenes, but also videos, as well. Saving some of the best for last, the SX230 is the only camera on the market at the moment to feature GPS, so you can have an exact map of the area where you took your shots and it features full 1080p high-definition output for video so with the right HDMI cable, you can watch your video either directly on an HDMI-capable high-def TV screen or upload it to your laptop for instant viewing if you have an adapter cable. You can find the right cable on major online stores.

Frankly, if you are looking for just the right gift for the photographer on your shopping list, the Power Shot SX230 by Canon may be a good idea, even if your photographer is dyed-in-the-wool “Pentax photographer.”
