This app is a pretty scientific experiment in deep photo editing. At RNI we wanted to make our photos look more special with less effort and more fun. So we created RNI Flashback — an app that works like film not like an app. Using Flashback is simple. You just press the button and it generates editing options for you. And then you choose the best one. Because you’re the boss. Unlike other apps, RNI Flashback has no pre-defined filters. Instead it mixes virtual 'chemicals' and creates a unique look every time you press the button. This transforms digital medium making it more true to life and more refreshing. Flashback is created for everyone. But professional photographers and aficionados familiar with shooting film will especially love it. Because Flashback works more like photographic film rather than like digital software. Unlike any other existing software, Flashback uses real film data and simulates the response of real film layers by light when processing digital colours. This results in a completely unique output which can't be achieved in traditional image editors with conventional tools. Some of its looks can be weird, some can render skintones too red. But some will be just absolutely fabulous, making for film-like colour harmony and colour separation, far beyond what’s achievable in any other piece of software you have ever tried. Experience RNI Flashback now. Bring custom artistic flair into your photos and never get bored again. -- #RNIFlashback Tag your photos with #RNIFlashback for a chance to get featured in RNI’s official newsletter, blog and Instagram @reallyniceimages.
