Mobile platforms are generally awash with social photo utilities with filters, of course, but (especially in the absence of Instagram) Fhotoroom stands out for a few reasons: the outrageous spelling(!), the range of filters and output options, and the frequency of updates, with the new version 3.0 (changelog below) coming in the last 12 hours.
Here's the quoted changelog for the big 3.0 update:
Updated tilt-shift filter
New before/after views
swipe left/right for filter
drag up/down to control slider
double tap to see before/after
Camera now supports full resolution auto-save
Faster multi-shot support
UI updates throughout
Good stuff. Here's Fhotoroom 3.0 in action:
As with Instagram, Fhotoroom is as much social image sharing as it is a creation tool; (right) trying out the revised (irregular) tilt shift tool on one of my night photos (you can either snap from within the application or load in something you took earlier with the main Camera app).
You can save effects-laden images to your local Camera Roll or to the Fhotoroom folder in your SkyDrive; (right) using the new gestures to swipe through various effects, one at a time - 'herc' has a certain 'something'....!
