I recently had brunch with Natalia Luckyanova and Keith Shepherd the co-founders of Washington, D.C. based iPhone development startup Imangi Studios. If you are new to Imangi Studios has also created the popular iPhone apps Harbor Master, Little Red Sled and Word Squares.
At this particular brunch they shared their photography application called Photomarkr. The Photomarkr application offers users the ability to put a custom watermark on any photo on the iPhone. The video above shares a quick demo that I shot with my iPhone (so bear with the less than perfect audio and video quality). The application is available for $2.99 in the apps store. Happy watermarking.
