I need a tool for posterising images taken with my iPhone. There is no image adjustments tool for the mobile application version. Would like to have similar features as present in Photoshop CS6 on my iMac.
I recently downloaded the photoshop express on my iPhone with the specific need of changing my image to b/w and then posterising as I require this feature for my art work. I assumed that the application would have similar features as that are in Adobe Photoshop CS6. Is there any version or application for mobile phones that has this feature?
