We have done posts before on high dynamic range photography-here is an excellent short tutorial on HDR. Included are sections on HDR processing software recommendations as well as image fine-tuning or tone mapping. Remember that HDR photography doesn’t require a particularly expensive DSLR camera, just one that allows you to manually underexpose or overexpose your photos. If you’re not really familiar with high dynamic range photography you should check out this article, absolutely stunning effects are possible with the technique. Now I’m just waiting for an iPhone app that will make it  possible to take HDR photographs on my mobile device. I guess I’m kidding, right?
Dygraphs: Visualization Library In JavaScript
Dygraphs is an open source JavaScript library that you can use to create interactive, zoomable charts of time series, capable of displaying huge data sets and enabling users to explore and analyse them. Check out the examples at the link, along with sample code to get you started. Looks dead simple to use. Dygraphs sends no data to any servers – it is client-side JavaScript, processed entirely in the client’s browser.  If you work with JavaScript you’re going to love this because as far as I can see it really transforms the user interface potential of the language into something terrific.
