I agree with Bob, it is some movement most likely. Try to proceed with the simplest experiment described in the Integraf booklet:
1. Get a sandbox, there should be at least 10 cm of sand.
2. Get a glass about 20-25 cm tall, fill it with sand and put in to the sandbox, try to dig it deep into sand.
3. Take a clothespin, put a laser diode into it, and dig it into the sand filled glass.
4. Turn the laser on. It should illuminate the sand surface at an angle about 45 degrees. Keep it running about 10 minutes before you start the exposure. Use batteries.
5. Take some flat, metal, simple object, such as a coin (just one piece!). Put it into the spot of laser light.
6. Put a card between the laser and the coin so that the card blocks light completely.
7. Put a holographic plate directly on the coin, emulsion facing the coin. Basically, the plate lies directly on the sand. There is also a coin somewhere in the middle.
8. After about a minute or two, slightly lift the card so that the plate is still not illuminated. Hold it in your hand, do not touch anything in the sandbox, hold your breath.
9. Wait about 20 seconds until everything calms down. Then remove the card so that the plate is illuminated.
10. After about 10 seconds, block light again so that the plate is not illuminated. Do it as fast as possible, but do not shove anything in the sandbox. Start breathing again.
11. Develop the plate. Ultimate plates are easy with the Ultimate chemistry, other plates may be trickier.
I assume you use a red laser and red sensitive plates.
This process should give you a hologram even in very poor conditions. If you succeed, you can try - one step at a time - to replace components, make more complicated objects, etc.
Good luck!
