Go out and shoot
Go Out & Start Shooting
The human brain wants you to find the perfect idea. By going out and shooting whatever random subject matter is there (no matter how dull) can create inspiration within itself. Go out and shoot that fire hydrant, doors, trees and whatever other random, dull, static objects you may find in your line of vision! It may lead you somewhere unexpected.
Find A Color
Go out and shoot one color. Narrowing your subject matter down to one color will make you see photographs you never would have otherwise. Different colors have different moods too. If you are feeling calm and cool, go shoot blue. Do you feel happy? Shoot yellow or orange. There are many internet resources that you can look into to explore the color wheel and emotional interpretation of color.
