I just got a hold of expired (6/2004) Kodak HIE for $1.49 USD per roll. Yahooo!!!! I've been researching the web & people seem to recommend straight D76 (no dilution) as the best approach to developing it. This is great because I carry 2 developers at home: D76 & DDX. However, I may have a problem using D76 with no dilution since the outside temperature is currently running at 100 degrees Fahrenheit with no relief in site. I may not get the optimal developing temp of 68 degrees unless I cool it down with a 1:1 dilution. Will diluting it cause too much of a problem? Also, has anyone used DDX for HIE and if so, at what time & dilution? Thanks in advance for all responses.
