Not surprising news, but worthy of a big mention. The Nokia Imaging SDK has had a new beta release (1.2).
This release brings all the goodness of the Phone library to the new, conjoined Microsoft platform across Windows 8.1 and Windows Phone 8.1. I am hoping to find a little time to play with the new SDK over the next week or so, but the sample apps and code look great. There are also sample apps in the Windows store, although the links in the site seem not to work. I’d suggest opening the Windows Store and searching for “Filter Effects” and installing the one published by Nokia.
