Some cameras lets you adjust focus after a picture is taken. Now, you can do the same for your lighting.
Isolite is a system of lighting accessories, created by Canadian startup Phototechnica, that splits your photographic lights into different wavelengths, allowing you to adjust the lighting ratios afterwards in raw editing.
The company packages such a solution as a series of light modifiers including a speedlight attachment called the Dualite, which separates bounce light from direct flash so you can adjust the relative brightness of each in post processing. Another offering will be a beauty dish for studio lamps.
Photographers can process the files using their regular raw editors or Isolite’s own imaging tools. Here are some examples:
- Shot with a single speedlight using Duolite
- Experimental: colourising each channel to create different colour lights
“Photographic technology has changed significantly in recent years but we still light photos much the way they did in the 1950s,” said Isolite creator Christopher Gergley, in a press release. “Our technology takes advantage of the surplus sensitivity in today’s cameras and the abundance of inexpensive but powerful flashes that many photographers already own, by adding a new kind of device that combines them to enhance control and offer new ways to create with light.”
Think of it like putting red, blue and green filters on your lights, then choosing your own mix of those channels in a black and white conversion. Gergeley told Lighting Rumours there is a bit more to it than that, however: “In theory you could say it is a fancy way to filter and convert black and white, but in practice [Isolite] is much more refined.
“There are no off the shelf “coloured filters” that could separate each light source into specific wavelengths/channels. There is also no current software that can handle and/or apply the sensor data for this type of application.
“But most importantly, we have taken this theoretical concept and packaged it into a simply and ready to use product, and we are offering it at the same price as other light modifiers.”
You can get a Dualite from CA$145, whilst a kit including a beauty dish will set you back CA$395. Phototechnica hope to raise CA$75,000 by 16 December 2017. For more information, visit the Kickstarter campaign page.
