Here's a picture, in two versions, that John A took. The street below I've walked many times (my chiro is in the brown building in the middle). There's just something about the picture I really like, and I told him so when he was here today. I'm not sure what it is.
And below those, a picture I took myself from the same rooftop, a few years ago.
By the way, tip about photoshop: under Image/Adjustments/, it has a "black and white" option, which lets you adjust how light or dark each color should be when converted. Sort of like putting a color filter on your lens when shooting in BW, only more flexible. You can make a blue sky very dark, or make greenery much lighter, and such things. In the picture above, I lightened Red, which made red bricks less heavy, and lightened up the red car.
