I come from a technical background and when I started photography (for real, not just bring one when I go to conferences around the world), I saw it as a technical feat, to tame the DLSR. Then at some point I realized that I had nothing to take photos of. and what would it be? That's the hard part of photography. what makes a good photo, what is a good subject? That's how I ended up here.
I cant believe that there's nothing interesting in a south american town. unless you are from one yourself (like I always say there's nothing to see in the town Im from , but visitors find lots of things), but it sounds like it is new to you. You need to open your eyes and be aware what is an interesting detail. sometimes it comes too late. you saw something and realize before bed that it was peculiar. write it down, so you remember to notice things like that faster next time. Like I was in Italy and saw a bike parked chained against a tree on a curb plateau in the middle of a many lane intersection on the main road, in a storm, and it was too late I realized that would be a cool image, depicting the typical italian parking mentality, but with a bike (which is scarce there!).
A good way to practice focusing on details is to avoid wide angles. I went to southern italy with two primes 28mm ad 50mm (manual focus!). I preferred the images from the 50mm!
