DCG Variables

Here are variables and their effect on the DCG process

• AmDi concentration - Lower redder less sensitive, higher bluer more sensitive
• Drying Temperature (Low ~20C) - Lower yields more triple helices, thus harder gelatin, clearer and more narrow band
• Drying Temperature (High ~30C) - Higher yields less triple helices, thus softer gelatin, less clear and more broadband
• Emulsion thickness - Thicker more narrow banded less light gets through, thinner more broadband
• Emulsion temp while mixing - Too low deforms on emulsion, too high pits, optimal centered at 120F
• Film freshness (film age) - Young broadband with milky tendeny, old narrow band and clear tendency
• Room Temp (exposure) - Warmer increased sensitivity
• Room Humidity (exposure) - More humid increased sensitivity
• Exposure Time - Longer harder bluer narrower banded, shorter softer redder broader banded
• Dark reaction time - Longer harder bluer narrower banded, shorter softer redder broader banded
• Fixer Time - Too short milky soft , too long harder bluer
• Light or heat fixing (if applicable) - Low light/heat softer broader banded milky, lots light harder bluer narrow band
• H2O rinse time - Too short non clear film
• H2O rinse temperature - Hotter broadband, lower narrow band
• IPA concentrations (ratios) - Faster increase in ratios (35, 100) broadband, slow increase (30, 50, 70, 90, 100) narrower banded, modifying 50% from 35- 50% shifts color towards blue.
• IPA time - Shorter broadband, longer narrow band
• IPA temperature - Higher broadband, lower narrowband
• Blow drying - Too slow uneven blotches, to short degradation of holo over time
• Wavelength - The shorter wavlengths the higher sensitive, and will greatly effect the other variables.
