Nothing’s Better Than Using Real Glass Diffusion.
But When Filters Aren’t an Option,
Variable Diffusion is the Next Best Thing.
Whether it’s due to a shrunken budget, a nervous client unwilling to commit to a look while on set, pesky filter reflections, or geographic distance from rental houses, sometimes cinematographers simply aren’t able to use the glass diffusion filters they know and love. Rest assured that Variable Diffusion’s Real Filter Emulations offer a great new option for post.
The Best Emulations Available, Period
Carefully calibrated to mimic actual glass professional diffusion filters via several methodic, tightly-controlled shoots, the Real Filter Emulations presets are simply the most accurate of any dedicated post production product. Months of meticulous testing & refinement in combination with our new proprietary algorithm has made this new higher level of emulation possible. Naturally, we fully expect experienced filmmakers and DPs to be skeptical... so feel free to download our free demo and check them out.
Subcategorized by Sensor Size and Focal Length for Proper Emulation
Those two factors affect how large of a physical area of the glass diffusion filter the image passes through, and we’ve painstakingly recreated those variations—so a diffusion filter’s look on a 200mm lens and its look on a 15mm lens are just as distinctly different with Variable Diffusion as it is with the real thing. These specifications by sensor & lens are absolutely essential for matching up to footage shot with real diffusion, making the Real Filter Emulations presets a great asset for maintaining a cinematographer’s aesthetic intentions when compositing greenscreen shots or sophisticated VFX sequences.
Diffusion is Likely What’s Missing From Your “Film Look” Recipe
The use of glass diffusion is an "open secret" amongst the world’s top DPs. If you’re looking to recreate the subtle finesse you see in the cinematography of your favorite films—both art house and blockbuster—then the Real Filter Emulation presets can help get you closer to that look. With lenses and camera sensors getting sharper and sharper every year, diffusion is becoming more and more essential to “take the digital edge off” for filmmakers who understand that emotional power is more important than explicit textural detail.
A Few Things That Glass FIlters Just Can’t Do
A common deterrent for using heavy glass diffusion is the resulting increase in perceptual noise. Applying Variable Diffusion does just the opposite—it effectively reduces noise in your footage.
Ever wish you could start a shot clean, then gradually increase the diffusion to complement a change in plot or character? Well now you can. It’s as simple as setting two keyframes with Variable Diffusion. The same goes for adding warmth to halation—subconsciously affect the viewer by having light from a bright window transition from neutral to a golden hue... then seamlessly intercut it with footage shot with real glass diffusion filters.
