The Negative Supply 4x5 Light Source Basic MK2 is the next of the second generation light sources from Negative Supply meant to replace the original 4x5 Light Source Basic. Designed with 35mm, 120 and 4x5 film in mind, the 4x5 Light Source Basic MK2 is created for all users in mind that need a solid, reliable light source with a high degree of color accuracy over long periods of time. As with our other light sources, the 4x5 Light Source Basic MK2 is also capable of taking our various adapter plates for film carriers to be used directly on the light source. You can also use our Pro Mount MK2 if you to mask off light from below, have leveling capabilities and an anti-static dust brush.

With learns from our recent releases, this light source comes with our custom designed and in-house finished internal acrylic that drastically increases brightness, improves CRI rating, and boasts perfect light uniformity for up to 4x5 sheet film. We’ve also developed new manufacturing methods that allow for a smaller light source that will still dissipate heat during long scanning sessions while also allowing us to decrease our cost and pass the savings along to you!

Recently there has been a lot of discussion about how CRI and TCLI should be used to compare light sources for film scanning purposes. We’ll break it down for you!

CRI is a metric used to tell us how a light source renders color based on human perception. What this does not tell us is how this light will render on film or in our case, a digital camera. The TCLI value will give us a more complete view of color accuracy and more directly relates to film scanning.

CRI is often the metric given when comparing light sources in our industry, though TCLI is perhaps more critical.

The TLCI value is averaged from the 24 colors from the MacBeth Color Checker Chart with the maximum value of 100 being the best. Light sources that score a 90 or higher are often seen as high quality light sources that will cut down on post production time.

The Negative Supply - 4x5 Light Source Basic MK2 - 99 CRI is far and away, one of our most popular items. People can't seem to get enough of it.
