Can we come up with a simple lightbeam photographing method that we can use among ourselves as our guide to photographing lightbeam.
This probably will compose of;
1) flashlight - must be the type commonly available in a household or store, need not be the expensive type.
2) digital camera setting - shutter speed, white balance, resolution
3) lightbeam & camera setup - (a) distance of flashlight and position of lightbeam against blank wall or target paper, color-shade of wall and type/form of target paper to be agreed upon (b) distance, height, and position of camera to capture lightbeam
4) Software image editing rules
With so many types of flashlights out there it is probably impossible for one of us to photograph every type of lightbeam there is.
The benefit is anyone using this method to photograph a lightbeam can come up with lightbeam's photo that all of us agree to be close to the actual lightbeam. Example: calibrating a lightbeam photo of Maglite-2AA in England to look as close as can be to the calibrated lightbeam photo of Maglite-2AA from CPF. Once setup is calibrated other lightbeam photos are acceptable as close to actual lightbeam as seen by the eyes and we can exchange with confidence photos for comparing lightbeams of different flashlight.
If manufacturers won't get together and come up with a standard to rate flashlights lightbeam, this is a cheaper and effective method for us to at least have a photographing standard to lightbeam photos.
Manufacturer can label its flashlight with any number of lux, candelas, or lumens they want to and we won't be confused because our lightbeam photographing method is calibrated to show photo as close to actual lightbeam at a set distance.
How about it guys. What do you think? Share your thoughts.
Darn! Another one of my crazy wild ideas.
