Negative Supply + FilmLab - Introducing Light Source Calibration Profiles

With FilmLab 2.2 for negative conversions, new features allow for more accurate and realistic scans, including profiles for Negative Supply Light Sources and Falloff Calibration.

Before: Natural vignetting caused by the lens and camera setup (plus minor falloff from the light source) cause the light corners to be brighter than they would with conventional scans. After: As you can see, the natural vignette is more pronounced, and the corners are not artificially brightened as in the top image. Keep in mind this is a GIF image, and email compression does effect image quality.

A Collaboration

Over the last year, Negative Supply has had the amazing opportunity to work with Develop & Fix, the developers of FilmLab. When we began talking through calibration science, we realized how important it would be to have accurate information about the light source spectral output. We also started looking at user calibration for falloff correction, which if you’ve used a camera scanning setups before, you’ll recognize as un-naturally bright corners due to scanning lens vignetting and light source falloff.

Lastly, we wanted to remind everyone that FilmLab offers a 14 day trial, so if you haven’t had an opportunity to try it out, now is a great time to.

We’ve include a few features below, but encourage you to check out his website for more information and example images.

  • Falloff correction. If you’ve spent time scanning negatives with a camera, you’ve probably been frustrated by visual issues caused by uneven lighting. Any unevenness in your backlight or vignetting in your scanning lens ends up reversed and amplified, which can give your scans bright corners and shifted colors. So we collaborated with our friends at Negative Supply to come up with a solution. Here’s how it works: When scanning a roll of film, take a picture of your light source with no film in front of it. Then tell FilmLab to use this image to correct for falloff. The result: evenly-exposed scans with no color shifting, and the true vignetting character of the lens you used to capture the original shot on film.

  • More backlight profiles: We’ve added built-in backlight profiles for the Negative Supply Light Source Basic and Light Source Pro. This makes it easy to calibrate for accurate colors when using these popular models. Thanks to Negative Supply for sharing spectral data on their lights so we could build these profiles.

We where incredibly honored to have our tools integrate with FilmLab, and can’t wait to see the work produced by our customers.

Best,

Saxon, AJ, & the Negative Supply Team

“Those are non-contrived real world examples using a macro lens at f/8 and a non-professional LED light source. It really is a killer feature - I never want to camera scan without falloff correction again--and it’s one of those things that once you see you can’t un-see, especially photos with blue sky where the top edge and corners look less blue” - Abe, the Developer of FilmLab
