It means different things to different people. For some, it's just the point-and-click of their iPhone or Android phone camera to catch that spontaneous shot. For other people, it's the serious, heavy duty DSLR camera that just came out, along with the $2000 lens. For me? It just means having fun finding a good shot, whether I'm using my iPhone or my Nikon. I'm not a professional, not by a long shot. At best, I'm a half-baked amateur, stumbling in the dark! lol
Point is, all of the images I've shared, they were all spontaneous. I just happened to be at the right place at the right time to get each of those shots. I wasn't sitting around waiting for the perfect shot to happen (there are people who do that, but damn, I'd get bored in a heart beat with my ADHD).
So, if you like to take photos, what's your preference? DSLR or your phone? Both? Are you a spontaneous-shot kind of person, or do you wait for the shot to come to you?
