Hoping to submit an update to Apple this weekend. I'm working on Version 3 of the Seaborn Books and Art iPhone app, which includes bug fixes, enhancements, and an entirely new feature called "Ocean View", a set of artistic image filters that will give any photo or illustration an underwater look. Version 3 of the Seaborn app is going live with five Ocean View filters: Shallows, Biologic, Beams, Rust, and The Tide.
Shallows attempts to recreate that shallow-water experience of bands and rings of light.
Biologic is a tinting and blending filter that allows you to merge your photos with some of the built-in underwater images of marine flora and fauna.
Beams overlays some vertical bands of light with some contrast and tint adjustments.
Rust…never sleeps. This will significantly alter the copy of the image you run through it. (See the examples in the workflow below).
The Tide takes a few passes to overlay a rising tide halfway across an image.
With this release the blending, alpha, color, and other values are set for each filter and can't be adjusted, but I'm already working on the next version, which will add new filters and allow greater flexibility with each--sliders for parameter values and the ability to add custom image overlays. In version 3 the filters employ a bit of randomness with each pass, producing different results almost every time.
Version 3 will also have built-in sharing features that allow you to post your Ocean View creations--with comments--onTwitter, Facebook, Tumblr, and other social platforms. You can also email copies of your images and save to the camera roll or photo albums on your iPhone.
