Buying a New Camera


In today’s world of advance technologies vast evolution of gadgets, photography has also been affected of the vast changes. It is not so easy to choose a camera that you will like because of it’s increase specifications and how can you buy a digital camera if u do not know the teminology of it’s important features.? Well, here are some How-To-Will some suggestions.

MegaPixels


Many of the Camera manufacturers produce a huge amount of megapixel(MP) on their product… some of the consumer says  to himself “Wow 7mp is more expensive than 5mp, and therefore is a better camera,”However, the megapixel count not only represents a poor measure of a camera’s quality, it’s actually somewhat irrelevant.

The Megapixel number doesn’t not speak to how good a camera is, only how many pixels it outputs. the real truth is that the quality of the lens and light sensors make a big difference than the number of megapixels, but these are things that cannot be satisfy in ways that the ordinary consumer can analyze critically.

Then there is fact that even 3.2MP camera,which is no longer in use for non-camphones can capture perfectly passable 6” by 8” photograph. For the low end of consumer digital camera standard is between 7 and  8 megapixels, allowing flawless 8x10s. Really, when you buy any camera lets you print 8x10s.

DSLR, COMPACT and PROSUMER which is best?

Physical configuration of the unit is one of the most important choices you will make in purchasing a digital camera.

DSLR

A  DSLR (Digital Single Lens Reflex) typically has a larger form factor and often has a detachable lens. A higher-end product, mostly of manufacturers put their best sensors and lenses in DSLRs. The professional photographers choice.

Pro: DSLR can produce a better picture than smaller and cheap camera.40d

Con: the larger form factor means you’re less likely to have a DSLR with you when you see that “gotta capture” sunset; also, the extra capability and increased quality is much expensive.

COMPACT


Compact camera (a.k.a “point-and-shoot”) are usually smaller, and non removable lens that telescopes into the body of the camera with is turned off. It has a inferior components than DSLRs. Some models come with Wi-FI networking capabilities for direct sharing photos online.

Pro: a compact camera is compact. It is easy to carry and become your habitual companion in all your adventures and a digital point-and-shoot camera. MosPanasonicFX35k_540t of digital compact camera has a “movie mode.” It is a affordable type of camera if your in tight budget.

Con: You could take a great a snapshots with a point-and-shoot, but trade-offs in optical quality will make themselves seen if you try to print at larger sizes.

Prosumer


Prosumer or SLR like cameras occupying in a middle ground betweencanon-powershot-g10-prosumer-camera DSLRs and compacts. Larger Type of camera, and they approach a DSLR in size. They have a higher quality components but lack in convenience. On the other hand it doesn’t have  a swappable lenses, mirror and reflex system which is the DSLR considered a premium item.

Aspect Ratio


Aspect Ratio: The ratio between the width of the image and the height are for example: The picture generated by a 5 MP camera that have a width of 2,592 and a height of 1,944 pixels, which represents a ratio of 4:3. Compact digital cameras typically have an aspect ratio of 4:3 while DSLRs usually have 3:2 because they serve to replace the old 35mm film cameras, which also were 3:2. Ultimately, aspect ratios will matter only to certain purists, and most consumers will be happy either way.

Tip: Recently, cameras with 16:9 aspect ratios have been popping up. This is the same ratio used by HDTVs and High-Def desktop cinema displays. Most 16:9 cameras can also shoot in 4:3, so you can have the best of both worlds.

ISO


A digital camera’s ISO settings represent the ability to quickly collect data. The term is rather defined the various film speeds before digital cameras were invented. The whole science of determining which ISO to use for a given shot is what separates professionals from amateurs. However, most, if not all consumer digital cameras automatically select ISO so you don’t need to worry about which setting to choose. The main thing to remember is that for darker shots, the ISO will need to be set higher in order to achieve high quality pictures; if the ISO is inadequate, the pictures will be grainy. If you plan on taking a lot of night shots or dimly-lit subjects like your friends’ bands on stage at a rock club, or otherwise pushing your camera to its limits, you might want to research the various cameras and find one that sports a more robust maximum ISO.

Sensor Size


As mentioned above, the sensor matters more than pixels for determining quality. The simple answer is that as the camera reaches the outer limit of its capabilities, you will begin seeing more noise in your shot. Generally, the more expensive cameras possess the best sensors. Unfortunately, there’s no easy way to determine the quality prior to purchase. Your best bet would be to read the forums and find out which make and model has camera aficionados buzzing.

Screen


Not all digital cameras have optical viewfinders, but all but the lowest of the low end cameras have a built-in display screen. For a variety of reasons, having a big and bright screen with a high a resolution is very important, you may use the screen to frame the picture as you’re taking it — it’s generally the case for compact cameras, but not supported by all DSLRs. You’ll definitely use the screen to review the pictures you’ve just taken.

Make sure you’re comfortable with the size and resolution of the screen. If you plan on taking many pictures outdoors, you’ll want a screen bright enough to see in daylight. Some cameras (typically in the “bridge” category) feature a screen which can fold out from the camera body and rotate, this is useful for framing shots taken at odd angles, shooting from the hip or high above your head.

Auto vs. Manual


If you are plan on taking your camera off automatic, you’ll need to be comfortable with the controls for shutter speed, ISO, etc. Are the menus clear and easy to navigate through? The best way to find out, try sort of playing around with a floor model, read the camera forums and find out what other buyers have to say.

Shot-To-Shot Speed


Some cameras take a moment to snap a picture after the button has been pressed. Especially compacts have a longer time between one shot and the next. Higher end models are much quicker and some even can take a series of rapid fire shots simply by holding down the button.

Storage


Be aware of the media the camera uses. Oddly, there are a lot of alternatives out there, such as MicroSD, compact flash, and Sony MemorySticks. Some older cameras even use floppy disks or burn to mini CDs. Most modern cameras seem to have settled on SD cards, which are very inexpensive and hold a lot of data. Sony MemorySticks are more expensive, and will only work in Sony cameras, but most Sony computers and televisions now come equipped with slots to read MemoryCards.

Batteries


Most cameras today use AAs, and this is the best because they’re cheap and rechargeable versions can be found in any store. Even ordinary AAs are fine, unlike some older cameras which require high voltage lithium batteries.

Other Features


Most consumer oriented cameras have a bevy of special features designed to lure in the undecided consumer:

Face Detection: The camera uses an algorithm to identify a human face and focus on it.

Video: The camera can shoot short clips of low resolution video, usually without audio.

Shake Reduction: The camera will compensate for shaking, especially in low light, high timed exposures. Two ways that this is particularly accomplished is in the camera itself, or in the specific lens.

Find a Store


Caveat emptor applies when searching for a place to purchase a camera. Be wary of stores, particularly online ones that sell cameras well below the average price of a large retailer — there are several scam sites that (at best) use bait-and-switch and (at worst) steal your credit card information. Shoppers can use any of several online sites or forums to research an online reseller’s reputation.
