Try some different developers with the benzotrialazole.(posted 9382 days ago)Before I found out that low-cost dark bags aren't really that dark, I ruined about $80 worth of Kodak HIE loading my developing reels.
Next time you venture into hot climates, try Ilford SFX 200 with B+W 092 filter. It has the highest storage temerature of any IR film I've seen (75F, I think).
