Dang, evening light is gorgeous! I didn’t have a camera, though. Darn! At least I had an excuse (I was mowing someone’s lawn). But anyway, like the title says, photography is kinda like video games, if it’s your hobby that is. Like in video games, it’s just for fun, so if it isn’t, stop for a while.
I don’t really agree with the ‘one camera, one lens’ philosophy for photographic ‘discipline’. Like I said up there ^, it’s for fun, so don’t force yourself into doing something you don’t want to do. If you want to, go ahead! But I’d rather use the right tool for the job. Creativity loves constraints, but don’t take it too far. I usually take only two lenses, the 60mm f2.8 and the kit lens, but might only take one lens. I think my opinion is: use one or two lenses at a time, but have the right lenses for what you want to do.
In conclusion, if photography is a hobby and not you job, ‘have it your way’. Do it to please yourself. If you are happy with the pictures you’re making, keep doing it that way.
