It does take some courage, polite assertiveness, to approach strangers with the camera, but the subject agreement and the interaction between shooter and subject I think makes for a more powerful photo. The viewer then may share in that interaction.
Best wishes for further success with subject-aware street photos, Ruben!
About the fear element
Take into account your own psycological status, when you are hiding. Project it to a scene of war.
Now within our war projection, imagine a small group attacking by surprise a larger army. Project it to yourself
Once you go for it, you will be in a totally different state of mind. YOU will be taking the initiative in the psycological internal war. YOU will be waiting for the suject to react. YOU will be mastering the initiative of the process.
For what is it good ?
When I saw Beniliam pics of this type, and I repeat this is just a portion of his pictures as he uses to picture unawared people as well, it is like you suddenly are passing a TV crew microphone to the subject: "what do you have to say to life ?" . It is a mini process of the like.
There are a lot of people around there, with lots of things to say without words.
Is this a forever tactic ?
No doubt that as a beginner I may be exaggerating the amount of these type of shots in the next future, until by some natural development it will get its proper proportions.
Not every situation and subject is suitable. I believe that with time one will be able to immediately smell the suitable situation and subject.
And I think that with an extra dexterousity, with a lot of exercise, I will be able to make two photos of the same subject, the first one while it is unaware.
Cheers,
Ruben
