While recently in San Francisco on a shoot for Apple (so good! - more to come later...) I took this photo from my hotel window. I have been messing around with Open Zoom, a free open source program by Daniel Gasienica that allows you to export high resolution images from Photoshop to be viewed on the web. If you have a mouse with a scroll wheel you can zoom in and out - if not just hold down the "crtl" when you click and that gives you navigation options.
