{|
| [[Image:DCGdiffeff.jpg | 400px | right]]Overexposure can have a drastic effect on dichromated gelatin. Test strips early and often are well advised.  The graph is from ''Lasers and Holography'' by Mehta and Rampal, 1993. It was reprinted from a paper by Chang and Leonard, "Dichromated gelatin for the fabrication of holographic optical elements," ''Applied Optics'', 1979.  http://holoforum.org/forum/viewtopic.php?f=7&t=652
