Fantastic!,
This is an exceptional slow shutter app. It offers editing features not available in any of the others. You can selectively bring into focus or blur any part of the image and then control brightness, contrast or saturation in the sharpened and/or blurred sections. You can then save the image as a project for future editing. Your work is saved at high resolution (5760 x 4320), or lower if you choose, in the iPhone 5. Highly recommended !
