This question already has an answer here:
I have been trying to get back to work for several years now. I'm an architect (or was) with children and where I am they don't cater for long hour day care facilities. So here we are me over sharing and still seven years later still without a job. I like photographing things. I own a canon Rebel TSi 550D. It's a superficial hobby. Superficial in the sense that it's genuine just lacks the proper knowledge and understand of the various AV TA ISO combinations. Can you kindly please point me to good website good techniques, anything that can expand my knowledge with photography. I need a good place to start.
