The PicShop app which is usually $4.99 is free today through AppGratis. The program has some great filters and effects, some interesting frames and you can have fun with text and make some basic edits. It is straightforward, with no directions necessary, and I suggest you just hop in and have fun. That’s what I did and I am enclosing an original photo along with a new version of the same photo after making changes within the PicShop app. I used the lomo filter, added two frames (balloons and leaves), a little red triangle called attention under extras, and some text. For what I was doing, I found it best to filter the photo first, then add the bubble frame and then the leaves frame on top of that, then the other effects.
