Get over the idea that only children should spend their time in study. Be a student so long as you still have something to learn, and this will mean all your life. ~Henry L. Doherty
Photography has been a continual learning process for. I am constantly on the search for making my images better, more creative, more interesting and so on.
I am currently learning more about lighting. I am reading and practicing and looking at other photographers images to learn.
What are you learning about? How do you go about learning? What works for you?

When the student is ready, the master appears. ~Buddhist Proverb

Have you ever heard of
Thomas Hawks $2.00 portrait project?

is a flickr group dedicated to the $2.00 Portrait project.
