Lume comparison

View Large On Black
First the watches in the light, then a shot with simulated subdued light - actually shot in complete darkness, but a strongly reduced fill flash was fired.
The ugly orange, green and white reflections are from LED's on my computer, scanner, printer etc. - these have been blocked off by black cloth for the following shots.

The shot at 22:12 was the first of the decay series, this is how it looks immediately after "lights off". Notice that the initial luminosity of the SuperLuminova on both Fortis is much brighter than the tritium tubes on the Ball.
For the following shots the watches have been covered up, and the entire setup stayed in complete darkness between the shots. The decay of luminosity for SL makes the advantage of tritium tubes clear in the second shot.

Check the time as indicated on the Ball watch for elapsed time between the shots

One word about the exposure: All shot at ISO 200, 15sec f/5.6. Opening up to f/5.6 means that overall DoF is shallow, but closing down to f/8 or f/11 will cause the luminous dots on the seconds hands on both the B-42 Marinemaster and the Ball become (for the camera only) invisible. Going for a 30sec exposure time would have caused "burn out" on the Marinemaster and the Flieger, because they are initially too bright. Overall it's a compromise.

The final shot shows how it remains "all night long". As mentioned elsewhere, a camera sees different than a human eye, so one final personal remark. Constant exposure lume shot series like this do favor tritium tubes.
Though it may not anymore be visible in the pictures because a constant exposure was used for all shots, the Fortis B-42 Marinemaster remains comfortable readable throughout the night (with full dark adapted eyes). On the new B-42 Flieger only the hands can be seen through the night.
