If you like Instagram, but wish you kept creative control and 100% ownership of your photos, then you should check out Pressgram.
It creates and publishes photos (with optional filters, just like Instagram) onto your WordPress site(s). There are 11 artistic filters to start with: Amsterdam; Empire; Lincoln; Fenway; Pioneer; Tokyo; Paris; Balboa; Milano; Spire; and Hollywood.
The Pressgram app became available on the iTunes app store today, and it is free to download and use. No advertising, and no in-app purchases.

Enjoy!
