What kind of photography, technique or style you wish you mastered?
Is there a technique or photography category or style you wish you mastered or would like to learn? What is it? Why that in particular? And what's stopping you?
I wish I could do a series of portraits similar to the one @Ian did last year or even a series of portraits like @Foggy publishes from time to time. Portraits is something I really wish I would shoot more of. Lack of time and lack of people skills is probably the main cause I don't.
