The Yahoo Groups seem to attract a certain number of spammers, so I cleaned out
the membership today.  If you were removed and wish to remain in the group
please send me an email:  bcat@...

Peter,

If you use some settings on manual based on the exposure guide, please
pass along your findings.  If you like, you may post some of your
results (50k jpeg) at the lightcode site in an appropriate folder.  If
you have questions please let me know.

Peter,

Thanks for bringing me up to date with you interests.  Does your digital
camera have manual controls for ISO, shutter speed and aperture?

The following folders have been added to extend the light range:

A1 - Upper limit of visual tolerence.
A2 - Bracket step for less light.
A3 - Bracket step for less light.
A4 - Bracket step for less light.

Z1 - Grass in starlight.
Z2 - Bracket step for more light.
Z3 - Bracket step for more light.
Z4 - Absolute threshold of seeing.  Black cat in starlight.

A ULC DECODER has been added that should be useful in locating the ULC
letter code when exposure settings are known.  The DECODER is here:

As the group owner of this forum on light, I encourage you to share
your photography and observations.  The intent of this site is to
provide a meeting place to post your photos so others can become more
aware of the lighting conditions that existed resulting in your
photograph.

There are 26 file folders in the ULC Photos menue (to your left)that
you can use to catagorize your light level from brightest to least
light.  Just post your .jpg image  file (50k or smaller files work
fine here) in the appropriate folder and post your comments (Post
menue to your left)including the ULC code, shutter speed, aperture and
film speed you used. Any additional information or comments, such as
location, weather conditions, etc., will add depth.  The decoder for
the ULC code can be found at:
http://www.blackcatphotoproducts.com/

I look forward to a discussion of light, especially as it relates to
the quantity or level of illumination and existing metering methods in
use, including EV, LUX, Lamberts, etc.

I think as the folders fill with images from around the world, there
may be a few surprises where the amount of light required for very
different scenes is the same.

Cheers,

Jim Lehman
