>>4451216 (OP)Apps and gear aren't especially important until you know what you want to shoot. You won't know what you want to shoot until you've done a lot of shooting, so just shoot! Go out and shoot buildings, cool textures, plants, interesting things, work your way up to people. Shoot in all sorts of conditions to understand the effect light has. Indoors, outdoors, just shoot and ask yourself if you're enjoying it. If you are, keep on trying new things. Watch some youtube, read some blogs, ask questions and post some photos on /rpt/.
The rest will come naturally.
