I have recently purchased a few speedlites (430EXII and 2 Yongnuo 560II's). I'm relatively new to flash photography and looking at all of the different modifiers available is pretty overwhelming. I like to shoot people, pets, and a little wildlife (probably in that order). I like to shoot both indoor and outdoor. My general approach to buying gear is to get stuff that will last a while. I'd rather pay a little more upfront and avoid the evolutionary process of upgrading later only to end up with the same equipment I could have purchased in the first place. I'd like to know which light modifiers (and size) you feel are more useful that I should purchase first and learn to use (soft box, grid, beauty dish, umbrella, barn doors, etc). Also, what brands and models do you have good experience and results with. I'm always interested in seeing sample photos of your work with said equipment if you are willing to share. Thanks in advance.
