Well, for starters, I’m able to run my game on the highest settings. But mostly it’s just Photoshop magic. 😉 I’m pretty Photoshop illiterate, which is why I rely on the skills of others – namely, I use .psd’s to help brighten my photos and enhance the saturation/vibrancy. 🙂 I’ve been using snapdragoned’s .psd for as long as I can remember (with various adjustments depending on the screenshot I’m editing). I’d like to give mir-sims’ recently-uploaded .psd a shot, too!
Edited to add: You should use a screenshot program, such as Fraps, to take pictures of your game! The in-game camera takes terribly low-quality pictures. 🙂
