Be an even better photographer
According to Lisa Clarke, a photojournalist from Australia,
these tips helped her to improve her photographic skills
over the years:
Before taking a photograph, make sure you check where
the light is coming from. If you shoot with the light
source to the side or behind the subject, you can create a
more interesting photo.
Be aware of the background.
Crouch or lie down, or elevate your position for an even
better view.
Take a step or two closer to your subject for more vibrant
detail.
On an extremely bright day, use the flash outside to prevent
harsh shadows on your subject.
Remember the rule of thirds: Cut your frame into thirds by
using both horizontal and vertical lines and place your point
of interest over the cross sections of the grid.
Include only one or two points of interest to avoid a confusing
picture.
Start shooting with your mind: Think of how you’d compose
a picture of a specific scene that interests you.
Don’t check the screen immediately after taking a photograph,
as you can miss out on a special moment.
