Welding Glass

Fixing colour casts with neutral density filters using the ColorChecker Passsport

Aug 1, 2018 by John Aldred 3 Comments

Recently, I posted a video on my YouTube channel on profiling my phone’s cameras. I do this because I like shooting DNG and then processing on the desktop. But the video raised a question from a couple of people about whether the X-Rite ColorChecker could fix the colour cast with long exposures using neutral density filters.

It’s something I’ve wondered myself. I don’t really shoot a whole lot of long exposures with neutral density, so I never got around to testing the idea. I have now, though. In this video, I compare three pieces of glass for long exposures. The B+W 10 stop ND, a very cheap Andoer variable ND and a piece of welding glass.

How to shoot long exposures for only $1

I find long exposures to be great fun, especially once you start really stopping down the light and extending that shutter to ridiculous lengths. The costs of getting started, however, can add up very quickly.

In Mathieu Stern’s latest video, which features long exposure photographer Thibault Roland, we are shown how we can get started very inexpensively using welding glass as a filter over our lens to cut down the amount of light hitting our sensor, and lengthening those shutter speeds.
