Depends on what vibe you want to give off, and if your business is for fun versus full time professional where you plan on copyrighting it. If it's the latter, your name won't do alone. Look at a thesaurus and look at synonyms for sunsets, trees, etc., and words to describe them. Then, create a name like, "_____________ photography by Jane Doe" as the full business, so you incorporate your name with your theme.

Beautiful Nature Photography

just don't put the word "photography" end of your page name. Use alternative words that relates to photography and attracts people

Nature Snap

Puff Shot (clouds = puffs)

Descant Horizon

be creative!

I see a lot of people put their first name and last name and photography at the end.
