Was browsing through Horenstein's Colour Photography book and found this interesting passage about color-polarizing filters that produce varying intensities of a colour (or sometimes multiple colours) as you turn the filter.
Yet I haven't been able to find any information about these online much less any available to buy.
Anyone know about this?
The passage in question is attached.
