I did what Lomographers often do - the opposite from what is written on the package and guess what, the risk that comes with it wasn't bad after all!
What rule of Lomography shall count now? The “don’t think” one? Well, we as Lomographers often do the opposite and call it cross processing, torture films and do some (funny) experiments and so on… So now I did something so simple that I am wondering, why it has not been done before: I developed a slide film as as it is – on E^6. The new Lomography Lomoslide 200 is a great film and I am very pleased with the results! Light blueish notes when you wash it normally. They very refreshing to see with the eyes, beautiful!
So forget about the rules (and what is written on the package) and process your slide films in E6 chemicals from time to time!
