Hi,

I've just published very simple app on Google Play which helps you to visualize how the scene will look using orthochromatic film.
You can enable/disable RGB color components to see how values will change with green or blue sensitive films.
This is only very simple way of doing such preview, because it only allows to disable RGB components, but if you are shooting green sensitive x-ray film or blue sensitive films you may find it useful.
App is free, without ads. I've wrote it for myself, but maybe someone else will find it useful.
