Having taken many, many photos of tea for my blog Oh, How Civilized and for Instgram, I've picked up a few tricks and tips on how to get the best shots. I want to share with you four tips that I find to be the most useful.
 Natural Light
I always aim to take photos in natural light. Setting up your tea near a natural light source is already going to set you up for a great photo. It's good to have just one light source to get the best shot. If I'm taking the photo at home, I'll make sure all indoor lights are shut off so I don't get any weird shadows.
 Three Angles
I like to take multiple shots and select the one I like the most. I'll always take at least one shot straight on.
Then another at a 45 degree angle.
And finally, one overhead.
 Rule of Thirds
I like to follow the principle of rule of thirds. Instead of putting the focal point in the center of the photo, place it at one of the four intersecting points as shown. Your camera will most likely have a option to turn the these grid guides on to help you figure out where the focus should be placed.
 Focus, Focus, Focus
You can ruin a great photo by not having the primary focal point in focus. I've taken many photos where I think "FOCUS FAIL!" I try to combat this by taking a couple of shots per angle to make sure I can get at least one photo that is super sharp. The part of the photo that you want to draw the eye to should be in focus. If it's not, take another.
Hope these tips help you take better tea photos!
