Nowadays it is very rare to see people without a digital camera. Before
buying, it is important to know their types and features. People always
go for cameras with more mega pixels for a better picture. Also, the
photo will have larger file size. Mega pixel means that the resolution
of the picture will be more than a million pixel.You take the number of
pixels lengthwise and multiply it with the number of pixels breadthwise,
if the value got is around one million pixels then yours is said to
have 1 mega pixel. Then comes the factor zoom-ability. Manufacturers
peddle their product mainly by specifying its zoom-ability. Zoom is of
two types namely optical zoom and digital zoom. Optical zoom is the
best, which is the level of magnification for the optics in it. In
digital zoom, camera makes the picture appear larger by increasing the
size of the pixels. It is always better to go for rechargeable batteries
rather than disposable ones because they are long lasting. But they are
dearer too.
Cameras are broadly classified into two types namely
compact cameras and digital SLR cameras. The choice of selection
depends on various factors, mainly the user. The users may be
professional, semi-professional, amateur photographer or occasional
user. Keeping these categories of users in mind camera makers produced
different models. Compact cameras are largely preferred due to various
reasons. It is very easy to handle because, manufacturers introduced
different compact camera models which help to take good digital photos
even with minimum learning curves. It follows simple point and shoots
strategy.
Compact cameras are available in all ranges from $100
to $1000 which makes them more well-liked among people who can buy
camera that suits their budget. In compact camera, so many
specifications have been arrived with the growth of technology. They
offer nearly five mega pixels with limited video capabilities. Camera
memory cards are available at cheaper prices. Normally compact digital
cameras have poor zoom-ability when compared to digital SLR cameras. But
these days compact ones support 3X to 5X zooms. Compact cameras are
obtainable in different dazzling styles.
With the maturity and
reputation of digital photography, photographers are also getting
matured. Digital SLR cameras are suitable for dedicated, professional
photographers. They are highly extortionate and offer many options. SLR
means single reflex lens, here the user can choose the lens according to
the environment like wide angle, close-up, indoor, outdoor etc. This
distinct feature helps in providing better pictures when compared to
compact camera. Since the user has control over the sensitivity to light
number in SLR camera, the image quality will be better. The user views
the scene through the lens not through the view finder and hence will
have enhanced precision.
Digital SLR cameras have shorter shutter
delay, faster auto focus, fast shooting and are capable of taking more
shots at a time. Digital SLR cameras provide more creative control over
the object. More than 6 mega pixel models are procurable in SLR cameras.
Other
types include ultra-compact digital camera, advanced camera, Micro
four-thirds camera and interchangeable lens unit camera system.
Ultra-compact camera are light weighted, small, easy to use, moderate to
high-priced and has small buttons and dials. Advanced camera also
called prosumer camera suits user having skill level between that of a
professional and a consumer.
They support high quality telephoto
zoom lenses with advanced features like filters, remote controls,
converter lenses etc. They show resolution between 5 to 6 mega pixels.
Micro four-thirds camera is like SLR but not SLR. They have sensors and
interchangeable lenses but they have no reflex mirrors and optical view
finders. Interchangeable lens unit camera system has different camera
units and each unit having its own camera lens, image processing engine,
image sensor. It offers good quality image but at the same time, it
costs the earth.
