Experimentation is the mother of success!! Try it, you might like it!
Back in the days of film you had to know about f-stops and aperture settings when using natural light and with flash. Now with digital and the program settings there is no thought process associated with shooting. Just shoot and look at the little screen and if it looks halfway decent call it artistic expression.
I think I am just old fashioned. I like crisp clear images. I am able and willing to do journalistic type photography using 'Natural Light', but why not sharpen those images using bounce flash, not direct flash. Any photographers images would get a boost if they would take a little advice from someone that is willing to share that tidbit of knowledge. Natural Light.......hmmmmmm, sounds like a drink!
