Exposure Time vs. Wavelength Tests in DCG

(click image to enlarge)

The following tests were done using the object I made out of square white cubes arranged in a stair step fashion. Here is an illustration of the object -  StairStepIllustration (click to view)

This hologram was made using 457nm wavelength. From right to left exposure time for each stair section is 15, 30, 60 and 120 seconds The DCG emulsion was 100-14-2. Alcohol temperatures were about 90 Degrees F. There was movement in the 60 and 120 second exposures.

Same Hologram on left that was reprocessed.

Water - 78-82F - 43 min, 15% alco -58 F - 2 min, 40% alco - 58 F - 2 min, 91% alco -58F - 2 min, 100% alco - 58F - 2 min, Heat Gun - High

This hologram was made using 457nm wavelength. From right to left exposure time for each stair section is 15, 30, 60 and 120 seconds The DCG emulsion was 100-14-4. Alcohol temperatures were about 90 Degrees F
