HI! I am an art conservation student researching holography. i have heard that silver halide holograms can fade and i do not comprehend how this could be, - if the final image is made of silver halide it could print out, darkening- but could it really fade? is something else occurring in the surrounding binder that would lower the refractive index and decrease vibrancy/ resolution? Is the image composed mainly of silver halide, or silver metal? also i would like to hear anyone's experience with other signs of deterioration. One more thing - I have seen only a few holograms and wonder if there is a visible way to tell the difference between a silver halide hologram and a dichromated gelatin hologram. Thanks for any responses to above questions! laura
