Often I like to use more than one photo editing program on my iPhone or iPad.
I first used XnSketch on this photo. I liked the soft almost cartoon lines. 19 different effects and you can easily share the photo on Facebook, Twitter, Flickr, Tumblr or Email.
I then imported the XnSketch photo into the House Photolettering app and added the headline. You can scale, crop or rotate your photo. Then add your type and share your photo. You can even get a printed postcard.
Go have some fun.
