Something I have become interested in learning more about is the effects of day time shooting, and night time shooting (more generally, lighting). I started to become interested in Steve McCurry's work because he took some photographs in a similar style as me but his seemed to capture much more emotion. So far I have learned how blurring and focusing a picture, along with the time of day of the picture, can effect the mood and emotion of the picture. Also weather can effect the picture.
This information is from Steve's website. The source of this information is the website of Steve McCurry, showcasing much of his work in separate galleries. The information that I've been reading is from this site, by viewing his photographs and reading his bio which is on the site as well.
