PreviewThis! is a photography app I have designed to help showcase your images as printed artwork when hung on a wall.
The apps main feature in my opinion is it’s ability to set a scale which allows you to add and work with image frames in real world dimensions. This allows you to easily showcase a variety of print sizes to potential clients. You can even add text annotations and share your completed previews to Facebook and Twitter via inbuilt sharing.
