Question

What is one technique that can help a photojournalist capture a great candid photograph? Always use manual focus. Anticipate what might happen. Make sure to introduce yourself to everyone. All of the above.

Answer 1

Manual focus might or might not be important. Very few subjects give you time to photograph them. 

Anticipation is a good answer. Mosts sports photos are taken because the cameraman/woman is either a good editor or he/she understands the game well enough to know what will happen.

I don't know that people have to know who you are especially if you are taking pictures of animals or vegetation. 

I have enough doubt that you can't pick the last one. So B.
