The good news is the "bright colors" you observed.vasimv wrote: ↑Thu Jun 13, 2019 10:12 am
Results are quite strange, i see bright colors are all over emulsion during 91% IPA bath (green and red mostly) and 99% IPA (shifting to blue) but after i try to dry slides with hair dryer - it turns to white mostly. I can repeat the process by dipping it into water and going through IPA baths again (31+75+91+99 at 29..30C) but after drying it gets just milky again.
Could it be your hologram of the dried layer has been shifted to the UV?
Have you ever tried putting your plates directly into the 99% IPA from your water bath?
If the water temperature comes close to the threshold temperature of your gelatin (28-30C with my gelatin), you should see very broadband reconstructions.
