BnW Visualization Loupe-thingie?

<p>Several years ago, I ran across a monacle-like loupe which was, if I recall correctly, produced by one of the major lens-filter manufacturers. When the photographer looked through the object, the scene was rendered in black and white, somehow.<br>

<br /> At the time I dismissed it, but lately I've found the idea strangely intriguing and want to buy one. Of course, I can't find it anywhere. Does anyone know what I'm talking about? Hope beyond hope, does anyone have a link to somewhere selling the cursed things?</p>

<p>Hey Amul,<br /> maybe the „Peak Mono-Tone-Viewer“ is the thingie you're looking for. I got mine several years ago from Monochrom in germany. Currently they offer a „Tiffen Black+White Viewing Finder".<br /> Hope this helps, georg.</p>

<p>Thanks, Georg! That's exactly what I'm looking for.</p>

<p>Out of curiosity, do we actually see black-and-white through the lens?</p>

<p>I can't remember the name or brands any more, but cinematographers use them all the time. I had one at one time, but didn't find it that useful. I think I paid around $500-600 at the time (around 20 years ago). Look around the film industry and I think you'll find them.</p>

<p>Wratten viewing filter, a Google search only showed a couple of ads, but I recalled the name from the Adams biog</p>

<p>Amul,<br>

the Mono-Tone-Viewer renders a rather dark and brownish view of the scene - the colors are muted and barely distinguishable.<br>

So it's not really black-and-white but close enough for me.<br>
