Does anyone use filters over their lenses for their MF3D photography?  

The reason I am asking is because I am often fascinated by the way my blue blocker sun glasses separate  greens. I would think that effect might enhance the stereo quality of a stereo rig.  

That, of course, leads to my second question (and yes, laughter is an acceptable response.)  Are there filters of the same color as the blue blocker sunglasses?

I live in North Carolina, and during the early Spring, particularly, we are surrounded with some serious greens. 

Thanks,

Al Whealton

The problem with colour filters on colour film is that you will get your enhancement, but there will be a destructive colour cast to the whole image. Your brain is able to adjust to a wide variation of coloured lighting (incandescent, fluorescent, daylight) without you seeing that colour cast. Your brain will also adjust to the colour of your glasses, but even then, you will notice the complementary colour to your glasses for a few seconds after taking the glasses off. 
You can get a good effect on sky and reduce reflection on various surfaces using polarizing filters, but you have to make sure you account for the filter in your meter reading.
On the other hand, if you are shooting in B&W, colour filters are great.

I use filters with my 3D World TL-120-1 or my Rolleidsocop when shooting Kodak Aerochrome (infrared).  Usually some shade of yellow or orange.  I have my filters in sets of 3 for the TL-120-1 so that I can meter accurately through the filter.  On my Rolleidoscop I just estimate the proper setting using the filter factor to adjust the f-stop.  I also use coloured filters when I'm shooting C-41 for cross-processing in E6.  Certain films have certain colour casts when cross-processed, so I try to balance the cast by shooting with colour filters. 
If you're after a filter coloured the same as your blue blocker sunglasses, I'd take your sunglasses to a photo show in your area and look through filters until you find filters that match.  When the PHSC hold their twice-yearly fairs, there's usually large tables filled with filters of all kinds for sale.
Regards,
Steven

I would think a quality UV filter may have some minimal positive effect on bringing out colors. I use them on many lenses mostly for protection. I think the effects you are looking for may be best adjusted with film selection. If you are looking for vivid colors, there are films for that. Many years ago I bought a filter with (I think) iridium coating which was suppose to make fall foliage "pop". It was expensive, and I got little use from it. Then Velvia came out and I forgot all about using it.

An interesting experiment would be to shoot a stereo pair through your sunglasses.  For the best results, carefully clean the sunglasses first, and then hold or tape a black card over the top of the sunglasses and on each side, to prevent ambient light from reaching your camera lens(es) and degrading your results.  If you do not have an automatic exposure system on you camera, be sure to compensate by manually adjusting your exposure accordingly.  Even if you take a light meter reading through the sunglasses, you might want to bracket your exposure for the best results.
