Here are some common issues that you may have to deal with and some tips on how you can use them to your advantage.
1 Compose in Thirds
To use the rule of thirds, imagine four lines,
two lying horizontally across the image and two vertical creating nine even squares.
Some images will look best with the focal point in the center square,
but placing the subject off center will often create a more aesthetically composed photograph.
When a photograph is composed using the rule of thirds the eyes will wander the frame.
A picture composed by the rule of thirds is more interesting and pleasing to the eye.
2 Avoid Camera Shake
Camera shake or blur is something that can plague any photographer
and here are some ways to avoid it.
First, you need to learn how to hold your camera properly;
use both hands, one around the body and one around the lens
and hold the camera close to your body for support.
Also make sure you are using a shutter speed that matches the lens focal length.
So if you’re using a 100mm lens, then your shutter speed should be no lower than 1/100th of a second.
Use a tripod or monopod whenever possible.
In lieu of this, use a tree or a wall to stabilize the camera.
3 The Sunny 16 Rule
The idea with the Sunny 16 rule is that we can use it to predict
how to meter our camera on a sunny outdoor day.
So when in that situation, choose an aperture of f/16 and 1/100th
of a second shutter speed (provided you are using ISO 100).
You should have a sharp image that is neither under or over exposed.
This rule is useful if you don’t have a functioning light meter
or if your camera doesn’t have an LCD screen to review the image.
4 Use a Polarizing Filter
If you can only buy one filter for your lens, make it a polarizer.
This filter helps reduce reflections from water as well as metal and glass;
it improves the colors of the sky and foliage,
and it will protect your lens too.
There’s no reason why you can’t leave it on for all of your photography.
The recommended kind of polarizer is circular
because these allow your camera to use TTL
(through the lens) metering (i.e. Auto exposure).
5 Create a Sense of Depth
When photographing landscapes it really helps to create a sense of depth,
in other words, make the viewer feel like they are there.
Use a wide-angle lens for a panoramic view and a small aperture of f/16
or smaller to keep the foreground and background sharp.
Placing an object or person in the foreground helps give a sense
of scale and emphasizes how far away the distance is.
Use a tripod if possible, as a small aperture usually
requires a slower shutter speed.
6 Use Simple Backgrounds
The simple approach is usually the best in digital photography,
and you have to decide what needs to be in the shot,
while not including anything that is a distraction.
If possible, choose a plain background – in other words,
neutral colors and simple patterns.
You want the eye to be drawn to the focal point of
the image rather than a patch of color or an
odd building in the background.
This is vital in a shot where the model is placed off center.
7 Don't Use Flash Indoors
Flash can look harsh and unnatural especially for indoor portraits.
Therefore, there are various ways you can take an image indoors without resorting to flash.
First, push the ISO up – usually ISO 800 to 1600 will make a big difference for the shutter speed you can choose.
Use the widest aperture possible – this way more light will reach the sensor and you will have a nice blurred background.
Using a tripod or an I.S. (Image Stabilization) lens is also a great way to avoid blur.
8 Choose the Right ISO
The ISO setting determines how sensitive your camera is to light
and also how fine the grain of your image.
The ISO we choose depends on the situation –
when it’s dark we need to push the ISO up to a higher number,
say anything from 400 – 3200 as this will make
the camera more sensitive to light and then we can avoid blurring.
On sunny days we can choose ISO 100 or
the Auto setting as we have more light to work with.
9 Pan to Create Motion
If you want to capture a subject in motion,
then use the panning technique.
To do this, choose a shutter speed around
two steps lower than necessary – so for 1/250, we’d choose 1/60.
Keep your camera on the subject with your finger half way down
on the shutter to lock the focus and when ready,
take the photo, remembering to follow them as they move.
Use a tripod or monopod if possible to avoid camera shake and get clear movement lines.
10 Experiment with Shutter Speed
Don’t be afraid to play with the shutter speed to create some interesting effects. When taking a night time shot, use a tripod and try shooting with the shutter speed set at 4 seconds. You will see that the movement of the object is captured along with some light trails. If you choose a faster shutter speed of say 1/250th of a second, the trails will not be as long or bright; instead you will freeze the action. This technique works well if you are using a tripod and if you are photographing a moving object.
