After losing my little Sony Cybershot at CES and mourning the absence of a Smile Shutter in my life to pick up my friend's most accidentally contorted rictuses, I decided I would buy myself a Canon G10 in the hopes that it would bridge me from retarded point-and-shoot territory into the world of DSLRs.
What I've learned so far has been laughable, but I'm pleased with myself: I no longer have to smugly nod when people talk about ISO or aperture to mask my ignorance. I actually know how to manually focus a digicam now, which is leading to some more interesting photographs. And, biggest lesson of all: I've learned using the flash on a camera almost always results in photographs that just suck.
This guide to DIY Lighting Hacks for digital photographers is good fodder, then. Granted, it's mostly aimed at the DSLR crowd, but stuff like the DIY flash diffuser and party bouncer card is still stuff I could fit into my Canon G10. And if you're a more advanced photographer than me — and it's almost impossible to imagine that you aren't — there's sure to be at least a few tips here that will save you a couple bills in equipment costs.
