Apparently they check addresses to find out whether or not you're in a residential area. I used my company name as I've ...

There is no doubt that Jeff Blyth’s recommendation of a distilled water rinse before the Pyrochrome or reversal or dichromate bleach eliminates the dreaded precipitate that is almost impossible to eliminate from the emulsion. But is there a chemical additive (and cheap besides) that could be added ...

Ok starting to put together a series of videos on Applying photographic lighting techniques to holography, and Applying the zone system to holography. This is nice because I have always wanted to cover this subject in detail, Joy Padiyar says its one of my strong points and realy makes my holograms ...

One of the most inportant things in holography is Lighting your subject. This is where some understanding of photography light will greatly enhance your holograms. In photography lighting ther are 3 sometimes 4 main lights 1 main light (this is your objects main light and can be direct or defused) 2...

When Ansel Adams took a picture of a mountain top, it's art. What's the difference? big diffrence his was based on skill and knowledge of light and aperture and understanding to control his medium to maximum the tonal range output, the zone system :D so based on his history it was his skill as a ar...

135mW (with reasonable coherence) is an impressive amount of power with TE cooling only and no extended cavity. Was there any kind of feedback to the diode (microscope cover slip, etc.)? I looked at the fiber optic face plate from Surplus Shed. That's pretty wild, I've never seen those before. It a...

for information... this is a Dave Battin laser , Te cooling, run at 135mw with good coherence

photo of hologram coming soon, was able to do nice clean trans hologram ... need to make it a bit brighter for show
