One of the advantages of living in or a near a city is the tons of possibilities you have for doing great street photography.
According to Wikipedia, street photography is "photography that features the chance encounters and random accidents within public places. Street photography does not necessitate the presence of a street or even the urban environment. Though people usually feature directly, street photography might be absent of people and can be an object or environment where the image projects a decidedly human character in facsimile or aesthetic."
Having said that, it would of course be awesome to start out with street photography in a city like New York, London or for example Amsterdam. You and your camera would hardly be noticed because there's just so much going on in the streets. Living in Jämtland, made us try our hand at street photography in the less busy and bustling but still fabulously great city of Trondheim.
Where it's an abundance of photographic opportunities in bigger cities, where we're living right now just have to be a bit more patient. Be patient and the situations will present themselves.
People are awesome photography subject, but street photography does not only entail shooting images of people, exactly like it says in Wikipedia. Here's some examples of street photography where it's not the actual human being being the main character.
Keep an eye out, be patient and look for great photo situations.
And when it comes to post processing, you'll be facing the choice of using colour or B/W in your images. Go out there and experiment. Be open and observant and the photographic opportunities will come.
