*** App Store Best of 2015 *** MIAN FEATURES: Dozens of custom, multilayered photo effects unlike anything available on the App Store, ranging from basic color and tonal to authentic vintage film emulations, textured finishes, and painterly and artistic styles. Built with scientific precision by some of the most talented artists in the mobile photography community, these effects truly deserve the “Formula” accolade. Each is meticulously constructed from components that are expertly-crafted by renowned photographer Dirk Wuestenhagen and that themselves are fully-fledged effects in the traditional sense including textures, filters, gradients, adjustments, and much more. Each formula goes through a vigorous testing process to ensure compatibility with a wide range of scenes, subjects, and editing styles from landscapes and cityscapes to street photography and portraits. Dozens of custom frames expertly-crafted by renowned photographer Dirk Wuestenhagen, which include high quality scans of vintage paper, worn fabric, weathered stone, and a multitude of other materials and substrates that are then refined, blended, and fine-tuned to perfection in an arduous post-processing regimen aimed at exposing naturally occurring character lines, blemishes, and impurities. Moreover, a great deal of attention is given to specific color tones within an overall limited spectrum of earthy hues that are deemed to work best with images. One-tap Auto Adjust tool that automatically analyzes color and tonal levels in an image and makes adjustments accordingly, thereby producing professional results with no effort whatsoever. Beautifully designed and streamlined UI that is intuitive and easy to navigate. A lot of thought and effort went into making the UI appealing to and accessible by users of all skill levels.
