Re: compact RGB collimated unit

The alignment problems are beyond me though you may be able to resolve your polarisation problem by rotating the diodes in their housing if they allow it.

I suspect they are glued in but access to the diodes looks easier than the green.

Re: Silver halide sensitivityy enhancer

This is an interesting read. So do the formate ions bond to the AgX when the AgX is exposed to the formate or on exposure to light? If it's on exposure to the formate then i'm guessing you could wash the plates after the formate soak in a similar way you do with ascorbic acid. This may stop the colo...
