Apply effects on your photos on your Apple device for free.

Ok, maybe I maybe a little slow on the trigger with this one, but it was such an Epiphany, I had to share.  I download Adobe PS (Photoshop) Express from the iTunes App Store and started to play around with some of the effects that came with it.  I tried to "reduce noise" on a picture of mine.  I applied the effect but it didn't allow me to save the picture, I had to purchase the advance App for this to work.  Then it hit me, I got the effect to do what I wanted I just couldn't save it.  So what happen if I just took a screenshot? (hitting the power button and the home button at the same time--you'll see a flash on your screen).  So do you know what happen?  I got a new picture of the picture WITH the effect.  WHO KNEW??
