You may not have known this, but one of the fastest growing new art forms is the taking and editing/manipulation of photographs on an iPhone; i.e. using the phone’s camera to take pictures and then edit them with software on the device. There are websites devoted to the topic, such as this one (from which the title of this post is taken).
As some readers here know, I am a committed (but amateur) photographer, and also having an iPhone I have experimented with this genre. Below is a photo taken in Castletown House, Celbridge, Co Kildare.
