Filterstorm for iOS is Updated and Discounted
Although I have many, one iOS app not yet in my photography tool box is Filterstorm (by Tai Shimizu) (App Store link). It has been highly recommended (especially in the Instagram community) by others and it has been on my 'want list' for some time now. Well, if you needed an excuse to buy it now (perhaps such as myself), it is has recently been upgraded to 3.0. The upgrade features a new interface along with some new features. It will be interesting to see how this app compares with other full featured photography post processing apps on the iOS such as
PhotoForge2 and Photo fx (by The Tiffen Company) (App Store links) among many others of course. It looks to be more similar to the former than the latter. Despite its name, I don't believe it is what we would call a photo filter app on iOS today. To my understanding it considers adjustments to exposure, color correction, sharpening, etc. as filters (as opposed to more artistic filters such as those in Instagram and others). It is now on sale in the App Store for half off (currently $1.99 from $3.99) for June 23-24, 2011.
This is a universal app for both iPhone and iPad, there is also Filterstorm Pro (App Store link) which is only available for the iPad at this point.
UPDATE: The latest version of Filterstorm is now titled Filterstorm Neue (by Tai Shimizu) (App Store link)
