I like too many things. Even the things I don't expect to like, I will often become fond of (except for math ... that one never took). So I don't know if I can say I have a true favorite with anything, let alone photography. But nature, wildlife, pets, and horses all bring me a lot of happiness and opportunities to learn. I also enjoy food, travel, and still life, and landscape photography ... so maybe I would have been better off identifying things I don't especially enjoy taking photos of. :) And really, the only one is people - because of how uncomfortable it makes me feel.
Nature is the complete opposite. It always brings me peace. I love to go outside and forget about all annoying things in life like work, bills, the news. When that stuff gets to be too much, nature is how I remind myself what is really important.
So here's some nature - a dragonfly I saw by the lake during golden hour.
