Nikon d90: I've owned three different dSLRs and I keep finding myself coming back to this beauty. I love the simplicity of my d90 and it's definitely my 4th child. ♥
50mm f1.8: I've owned both the f1.4 & the f1.8. I currently use the 1.8 & it's what I would definitely call one of my go-to lenses. For the price, you can't beat the quality!
Computer programs: Adobe Photoshop CS5, Lightroom 3.0
Lighting: 99% natural light shooter, but I also have a portable studio setup with some cheap-o lights I ordered off the internet (which I barely ever use or even bother to drag out because I prefer natural lighting over anything!).
I'll update this more soon with more stuff. Want to know anything else? Feel free to ask!
