THIS is the way I like to do it...
1- Go downtown...now, I'm a country boy so when I go downtown (Detroit for me) I'm knocked out by the tall buildings. It's much worse when I go to Chicago or Toronto...if I ever see New York I'll prolly die.
2- Shoot pictures at as Hi resolution as you can. As straight on as possible.
3- Use Photoshop to 'RE-square' the imagery using distorion tools. Retouch the crap out of it.
4- Also in Photoshop make art for your depth(bump or displace), reflection, ambiance (for backlights) as you see I did.
5- In Hash- use minimal geometry and lots of decals. Scale to taste.
I have more like this...will try to upload later...ENJOY!
OK!
Thanks!
