The Negative Supply 4x5 Light Source Basic MK2 99 CRI is an updated version of one of their all-time best selling products. It is an evolution in every way for film scanning.

The 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 their other light sources, the 4x5 Light Source Basic MK2 is also capable of taking their various adapter plates for film carriers to be used directly on the light source. 

This light source comes with their 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. They’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 the cost and pass the savings along to you!

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

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

The TCLI 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.
