Oh, this one I have been waiting for. I remember when I was playing with my Lomo LC-A ages ago: it was always great to have these non-perfect randomly changed pictures. And when the first mobile phone cameras came out I knew: we need a “Lomo” app for those shabby camera phones.
Fast forward to today: we now have Hipstamatic, Instagram, and many more. Image manipulation with preset filters in any shapes are defacto standard.
PhotoStyler from Neatberry is exactly that app. You can use pre-set filters, make your own, and you can also do batch processing. That’s GREAT!
It’s available on the Mac App store or from their Web site for ~30€.
