The first question I am usually asked by aspiring photographers is "What sort of studio/lights/equipment do I use?". I've been thinking about it a lot recently having just started teaching 2 adult education classes in photography. In the good/bad old days of film I used one camera (Horseman LX), one lens (Schneider 135), one film (Polaroid Type 55) and one paper (Kodak Ektalure).
Now I find that I use one camera (Sony Alpha 350), one lens (Sony 50mm Macro), one film (digital) and one paper (Hahnemuhle PhotoRag 308). So no matter how much things change they also stay the same (relatively speaking of course).
Oh yeah, the one thing I forgot from that list is my fabulous lighting setup, natural diffuse daylight from my kitchen window.
Be well and enjoy
