Filterstorm is overkill for most peopleâ€”and it should be. It was meant to be powerful, and though I try to make it as easy to use as I can, power necessitates complexity. Gridditor is the opposite. It’s the app I can tell all my friends to use regardless as to whether or not they know the first thing about photography. It is meant to be fast, easy to understand, and in some respect to teach by forcing people to look at how each filter behaves and interacts with others.
The basic premise is simple: arrange thumbnail previews in a grid, and let the user choose which one looks best (tapping on any thumbnail will bring up a larger preview). Lather, rinse, and repeat until satisfied. To generate the grid of thumbnails, I assign one filter to each cardinal direction. By default, up is contrast, down is vibrance, left is darkening, and right is brightening. If you choose a thumbnail directly to the right from the center you get that one filter, in this case brightness. If you go in two directionsâ€”say, up and to the rightâ€”then you’ll get both the brightening and the contrast filters. After a choice has been made, four new filters are pulled in at random. If the user doesn’t like the filters chosen, they can be specified manually, or a new group of random filters can be pulled in by selecting the center/unmodified image.
By showing a big grid of choices rather than having the user select a filter and control its strength, more options are shown at once, unexpected possibilities can arise. It also allows for very quick choice and is great for making some minor adjustments to an image before uploading it to wherever it’s headed.
I’m very excited to get Gridditor out onto the app store, and it should be available in the next couple weeks or so. In the mean time you can see the website, including a video of Gridditor in action on iPad at http://gridditor.com
