Ask for permission
Before you snap a photo of a person or scene, show respect to your setting and the people in it. Ever have someone come into your workplace and stick a camera in your face because they think your culture is interesting? No, because that would be rude, awkward, and out of place. Ask before you start taking pictures and you will see how people open up, which gives you the opportunity to take even better shots.
As a photographer you need to be patient to wait for the right moment. It takes some time to understand the culture and let the people get familiar with you. Best is to travel solo or with fellow photographers.
Bag your bias and open your mind
We all have biases and it can be tough to recognize and curb them. Do your homework before even getting to where you’re going. Squashing bias and preconception will make you look at something new as a blank canvas, allowing it to change you. You, in turn, can take your newfound point(s) of view into the photos you take and experiences you choose.
