= = = = = Brought to you by the award-winning app development team, Pixite. With Matter, alter the reality of your photos by seamlessly adding unique 3D objects to them. Choose from 4 packs of models ranging from simple geometric shapes to complex, architectural structures. Once you’ve chosen your object, select from a range of visual styles to make it reflective or refractive, opaque or translucent. Output high resolution images and even videos. Make your edits even more realistic by adding and adjusting the model’s shadow. Fine-tune the shadow's position, opacity, and strength. Use the built-in masking tools to erase portions of your model or shadow to seamlessly blend it into your photo's environment. Use the unique video export feature to create short animated loops of the object spinning, pulsing, and hovering in your photo. Adjust the rotation speed and direction for a different effect every time. Make sure to share your Matter edits on Instagram using #matterapp for a chance to be featured.

RNI Aero will effortlessly make your photos look mesmerising and surreal, like if they were shot on an infrared film. The RNI Aero filters are inspired by Kodak Aerochrome - an infrared film created for military and surveillance purpose. The original Aerochrome has been discontinued a while ago, but this project aims at recreating its look and preserving it for the generations to come. This app has been created by RNI - analog photography and digital imaging expert company based in London. Showcase your work on Instagram with #rniaero for a chance to get featured by RNI. FILM-BASED PHOTO EDITOR The RNI Aero filters are born from real infrared film. The app comes with a versatile introductory package of free film filters.
