FX Photo Studio HD by MacPhun LLC
There are a number of photo apps available for the iPhone and iPad. Sometimes it's hard to choose or find the right one to suit your needs. Like other apps, FX Photo Studio offers plenty of options to choose from. What sets it apart from other apps is the ability to selectively apply masks to isolate your filter effects. Each photograph therefore has the potential to combine several different effects. Thumbnails of each filter guide your selection and adjustment guides are available to fine tune your image. The MacPhun team (now known as Skylum) are highly respected developers who design for iOS and MacOS.
