Quote: "I would have thought it to be a simple art to learn. So what is there to photography which needs a class to get good at?"
Wow!!! I've been doing photography for so many years, and every time I go out, I get a little bit better. It's such a complex art, you wouldn't believe. For example, how would you do the following...
Take a portrait against the backdrop of a window?
Take a landscape, with high contrast in the clouds
Take a butterfly, and make sure the flower it is on is in focus, but the next flower back is blurred?
Take something in focus when it's not actually the centre-point?
Expose for the foreground
and the background.
Capture emotions?
Pan and shoot?
Focus on a car travelling at 150 miles an hour?
Photograph water in motion?
Photograph water in an action shot?
Photograph blue water?
Take photos into the sun?
Create a silhouette against a high-colour backdrop?
The list is endless!!! These are just the subjects. Within each one, you need to find a full range of tones, compose the shot, and on and on...
