Choosing an effect from the left brings up many thumbnails of different ways to apply that effect. This is instant and the thumbnails can be scrolled through and tried at full screen size. No problem if you change your mind as the app has many levels of undo.
I have chosen Art - Sketch. With most, probably all, effects there is a slider which lets you choose any state between the original photo and the full effect. Here I have adjusted the effect to allow some of the original colour to mix with the b/w sketch:
You are not limited to using one effect, many can be used one after the other to build up the result which pleases you. At any and every stage the result can be applied and saved to the iPad Camera Roll, sent to other apps which have the facility to import a photo, emailed, sent to Twitter, Facebook or Flickr. If you use Dropbox then that comes up as one of the 'other apps'.
This started off as a b/w Moon in a black sky:
There are far too many different effects in PicsPlay Pro to cover here such as the HDR type effects and the way some can be applied to part of a photo. For me this app was well worth 69p of my pension and would still be a great aquisition at its previous £1.49 It looks as though it could be going up to £2.49 soon.
When I want to get photos in or out of the iPad I use a PC program called iFunBox which allows access to all parts of the iPad much more easily than battling with iTunes.
