I have since my teenage years loved to take photos (for almost 20 years now).
Mostly I enjoy photographing nature (like plants, animals, etc). I have a Nikon D3100 with a longer zoom lens, a normal zoom lens, and a macro lens. Lately I have mostly enjoyed using my macro lens and photographing plants.
A great thing to combine is hiking in the mountains and photographing. Also travel and photography is a great combination.
I always edit my photographs digitally before selling them or showing them to people, at least if I want to get the most out of the photo. It makes such a difference.
