How to start a photography essay?
My subject is photography fantasy and I have to write abut 3 photographers. I have the 3 photographers, I know who I’m writing about. But I dont know how to do an introduction – I always struggle with these in essays.

So far I’ve put this:
Fantasy is a genre of imaginative fiction involving magic and adventure, especially in a setting other than the real world. I have chosen to look into fantasy in photography because

should I put why I chose to look at it and what else can I write about that should be in an introduction?
thanks 🙂

I never do boring traditional intros, and I always get A’s.
Start large and narrow in. Photography>Fantasy>your people.

Lets make up some names here so I can give you a layout. Mike, Sam, Bob are my photographers.

Photographs are a great way to capture a moment in time, whether real or imaginary. With photographs one is able to show others something they experienced. In fantasy photography, it is a great way to show others an image in your mind. Blah blah blah, then integrate your 3 writers..”Bob uses whatever style to show blah blah”…etc

I could help more if I knew more about what you were writing about. Hope that helped tho.
