A simple test to show how we can use iOS photo app's standard filters. (In version 1.5, it won't work before 1.5 update)
Simply edit the photos as you wish in iOS photo app, crop, rotate, add filters, and the use in the pixotale, your editing will be there. You can edit same photo again and again and use it multiple time in same story.
Here is an example:
And the crops works too:
Crop+filters also works:
Rotate, auto enhance, red eyes... works too...
As a plus, you can also use Pixotale's filters and editing on top of iOS's!
