Flash
photography can be a great tool in the absence of insufficient
natural light. Then again, there are situations like live concerts,
theatrical performances or even film shoots where you are required
to capture everything without using a flash. Flashes might light up
your subject, but it can also flatten the image and make it appear
one-dimensional. This makes your image look lifeless, with no depth
or play of light and shadow (except for the harsh shadow behind the
subject). This is particularly true of pop-up flashes that come
with your camera. Without a diffuser that normally accompanies
external flashes, these built-in flashes lead to over-exposed
images and cast a bright spot on the subject, marring the beauty of
your image irreparably.
Here is where the following tips to beat low light situations might come in handy.

Observation
Become an observer. See how the light falls on your subject to
author creative images that have a two or three-dimensional effect
on them. See where the light falls and how it reflects on to your
subject and your camera. If direct sun light is unflattering to
your subject, look at another angle to capture their best side.
Study the area around your subject. Look at the props you could use
to avoid direct light like windows and curtains to distill the
light entering the room, for example. See if you can place leafy
plants in the way of sunlight and get a better shot, or better
still, see if you can keep a foam board, white umbrella or any
white cardboard in the window or door to block direct sunlight.
This will also serve as good reflector that will enhance the
available light in the room. Once you’ve got a fair idea of
the light and shadows in the subject’s surroundings, you will
get a fair idea of what works and what doesn’t with the
flash.
Crank Up the ISO
Once you’ve taken care of blocking harsh light and enhancing
the indoors (or outdoors) with reflective light, it’s time
for step two. A good way to combat low light is by using a higher
ISO. Your ISO simply means the amount of sensitivity of light
falling on your sensor. Simply put, the more you increase the ISO
(from 100-1600), the more chances of creating depth in your photos.
Now, you don’t want to alert them to it, but you still want
to capture the action on your chip. In this case, you simply adjust
the ISO to a higher setting manually. If you are unsure, you could
set the camera on ISO Auto and the camera does that job for you.
Not only that, but you can take even better photos, provided you
have a tripod handy. This is because, a higher ISO also means a
longer shutter speed. So the camera lens is exposed to the subject
for a far longer time than usual. Even minute camera shakes could
result in blurred images.

Tackle Grainy
Images
Once you’ve set your camera to a higher ISO and got a tripod
to shoot your pictures, you are set for the next step of tackling
noise. This is nothing but the grainy textures that show up in
images where there isn’t much available light (called
‘ambient light’). One way of cutting out this problem
is to go for noise reduction software like Noise Ninja, Neat Image
and several others. Just type ‘noise reduction
software’ in Google, and the site will throw up many options
where you can resolve the noise issue.

Faster Shutter
Speed
Okay, you’ve tackled noise, but you don’t have a tripod
and therefore, your image might appear shaky and blurred. Not to
worry. You can decide on the next top ISO which will then enable
you to select a faster shutter speed. Yes, here is where you have
room to experiment with different shutter speeds to bring about
stability in your shots.
Shoot RAW
Now, there are different formats in photography: jpeg, tiff and
raw. Jpegs are great for compressing large images into smaller
ones, as are tiffs, although that's a sizable format. Still, RAW
formats are the heaviest – a 1MB jpeg file becomes a 9MB RAW
file. While you can do limited tweaking of your photos in Photoshop
and other photo-editing software, you can go the whole hog with a
RAW image. This comes in handy when you want to weed out things
like noise, color saturation, over/under exposure, red eye
reduction, blurry images and so on. Therefore, if your camera
memory permits (and I suggest you go for at least a 4gb card for
your Digital SLR), go for a RAW image.

Aperture Mode
Another way to avoid shake where tripod usage becomes impossible,
say at a tightly packed private party where you are required to
move around a lot, you could also take refuge in the
‘Aperture Priority’ mode. Just go for the lowest f-stop
on the fastest lens you have (f1.8 or lower if you can). If that
still causes your shutter speeds to be too low to hand-hold, then
you might even set exposure compensation down by a stop. This will
increase the speed a little. Later, in post editing, you could
increase the exposure. Talking of fast lenses, there are affordable
primes as well, like the Canon f1.8 50mm which is $80, or the f1.8
85mm canon USM that is just over $300. That extra stop or two can
seriously make the difference in low light / no flash
photography.
