About this app
The Official LEE Filters Diffusion Comparator enables lighting designers to directly compare different diffusions lighting a model. As the video plays simply tap to switch the diffusion in real time. It's a great way to select the perfect diffusion for your next project. The comparator is built from video clips of a real world lighting setup using a single M8 source and each and every diffusion in the LEE range. By switching between them you'll immediately see how each moulds the shadow in subtle but distinct ways. You'll also notice any colour balance changes. • Switch diffusions in real time as the video plays • Pause to compare similar frames, for instance a long shot or profile view • A commentary track by DOP Don McVey is also available The app includes various design refinements so you can get the most from this tool: • This is a universal app designed for both iPhone and iPad • On either device switch between portrait and landscape views and retract or expand the menu to get the best possible view • Collapse the diffusion list so you can quickly jump between any filters It's a great tool to learn more about lighting with diffusion and for creative experimentation before getting on set.
