Union review
Union provides your iOS device with photo editing capabilities more commonly found in professional desktop photo editing software. This allows for extremely artistic and creative effects.
Pros
Quick creation tool: You can combine two images very quickly in Union. You just choose the background and foreground images and then start to erase the foreground until you're happy with the result. You can achieve a great product very quickly.
Magic wand tool: The magic wand tool works very well for selecting large areas of a photo quickly. You can adjust the sensitivity of the tool and then see exactly what parts of the image those changes impact.
Non-obstructive zoom: Union places the zoom window above your fingers, reducing visual obstruction.
Cons
Slightly confusing: The many options and the control interfaces take some getting used to. Some good video tutorials would be welcome.
Bottom Line
If you want to create images that combine multiple photos into a single image, you'll be hard pressed to find an app that is smoother or quicker to use than Union.
