For people that enjoy photography or that are fairly decent at it, they usually have a page that lists 'what's in their bag.'
I'm gonna go out on a limb and disclose to y'all what's in my bag. You ready for it? You sure?
A camera. That's it. Not kidding.
Ok. For real though. It's a Nikon D3100 with a stock lens (18-55mm f3.5) and a prime lens (50mm f1.8). For the most part though, I use my iPhone. It's lightweight, easy, convenient, and I can slip it my pocket.
I also use Lightroom.
