Are you planning to buy a digital camera? Do you already have a digital
camera? If both answers are yes then this basic tips and tricks are for
you.
Digital photography seems easy to the amateur compared to analogue film cameras but taking really good photos requires knowledge and understanding of photography.
Here are the basics along with some tips and tricks to produce better digital photos. Here I will go through the following aspects:

Storage and image quality:
Most
digital cameras allow you to reduce their resolution or increase the
compression to get more images on to the memory card. However, both
these will reduce quality. Unless you have a very small memory card,
select the highest resolution pictures and lowest Jpeg compression
settings.
When it comes to how much resolution you need, it depends on how much
detail you want to capture. More mega pixels means higher detail and
bigger enlargements or crops before you the image starts to become
pixelated.
For a 3R size photo 1024*786 resolution should be just fine.

Memory:
Memory
is an important part of digital photography but will become less of an
issue in the future as storage capacities become larger and larger.
Storage capacity dictates how many pictures you can take and how high a
resolution they can be.
There are several memory card formats available for different cameras.
· Smart Media
· Compact Flash
· xD
· MS
· SD
· MMC
I’d recommend buying a 1GB memory card.
Memory cards can be erased and reused but you’ll want to back up your images first. Most people copy their snaps on to a PC or laptop.

Battery:
The
lifespan of digital camera batteries depending on the model and usage,
but one to four hours of solid use is about standard. In practice you’ll
power down the camera between pictures, allowing you to take around 50
photos over a period of several days.
Tips to save your battery:
· Switch off the flash
· Do not use the LCD view finder.
· Switch off button beeps and other sound effects.
· Use high drain rechargeable batteries such as Ni-MH 2300mAh because disposable alkaline AA cells won’t last long in a digital camera
· Use a card reader to move pictures onto your PC instead of connecting the camera and using its batteries.
· If you own a SLR digital camera, purchase a spare battery and the battery grip attachment.

Exposure:
All digital cameras have an auto setting which calculates what it
anticipates will be the most suitable exposure. Most devices get it
about right, but mistakes happen. There will also be times when you want
a darker or brighter result.
Deliberately underexposing an image can be an affective way of
cutting through haze or bringing out a colorful sunset. Overexposing is
also handy if your subject is dark and you can’t or don’t want to use a
fill-in flash. Remember to set the exposure compensation back to zero
afterwards though.
Focus:
Digital cameras have an auto focus mode but, as with auto exposure,
this can go wrong. A common problem is where the subject in the
foreground is out of focus, but the background is in sharp focus. It’s
clear that the camera has focused on the background by mistake.
The first time you try this it’s easy to press the button all the way and accidentally take the photo early. It takes practice to learn the right pressure, but at least a digital camera lets you delete the pictures that went wrong.

Depth of field is a technical term referring to how much of the
picture is in focus. A large depth of field has lots in focus, while a
shallow depth of field only has the main subject in focus.
The depth of field is controlled by the lens aperture, described by its f-number. Smaller f-numbers mean shallower depths of field; larger f.numbers mean larger depths of field. Digital cameras generally have a range of f-numbers between f2.8 and fl1. (You can read more about DOF here.)

Zooming:
Most digital cameras are fitted with optical and digital zoom
facilities. It’s best to disable the digital zoom as it just crops the
centre of the picture and enlarges it, thereby losing quality, The
optical zoom uses lenses to get closer to a subject with no loss in
quality, but zooming in and out also has other effects.
Camera Flash:
The key to using the flash is to understand its limitations. Built-in flashes are only effective over a distance of a few short metres and, beyond this, have no effect at all. Unless your subject is within a few metres, you might as well switch off the flash. It’s also a good idea to
switch off the flash when shooting through windows to avoid reflection.

LCD View finder:
A big advantage of digital cameras is being able to use the LCD screens to check a photo immediately after taking it. This is invaluable
for checking exposure, and composition, not to mention potentially blinked eyelids. Beware, though, as the screen resolution is too low to confirm whether a picture is definitely in focus. So if you’ve got a particularly important shot, play it back afterwards and zoom in closely to ensure everything’s fine.
