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.

The call

The clearest difference is rating: RNI Aero at 4.7 against Perspectivize's 3.7. RNI Aero also leads on update cadence (every 2 months vs every 13 months) and ratings volume (250 vs 77). Perspectivize's advantage is in-app purchases (none vs 3) and iOS requirement (9.2 vs 15.0). On price, review sentiment, ads and device support there is nothing between them.
