Union is a more powerful and artistic photography app than most. Rather than simply being a matter of applying one of a few filters and enjoying that result, it's a lot more hands-on. For that reason, it'll take more practice to perfect but it'll be worth it in the end as the results can be really quite attractive.
The app works via a series of layers. Users initially load a background image - either from their camera roll, by picking out a color for a solid image, or using a transparent layer. Then they do the same with the foreground image, building upon what's already there with masking options completing the process.
Each step of the way there are different settings to adjust. Besides the usual bunch of saturation, brightness, and temperature, there's also the more interesting prospect of manipulating the foreground image. One can make it more or less prominent on the image, even turning it into a shape that changes around what can be seen. Masking further adds to what can be accomplished by the end.
The effects can vary from quite subtle to much more dramatic, and it's satisfying to gradually adjust things to change how they work out. On the iPhone 5 everything takes hardly any time to do, proving quite convenient. Plus there's always the undo button, which simplifies going back a step.
Union does take practice though. Early results won't look as great as the App Store examples, but such things are possible. It's a fun app to mess around with as one is always guaranteed a look that's different from anything else out there. There's the usual selection of sharing options too, so it's easy to show off some good results. As a more powerful option than most, Union does the job well and attractively so.
