howard_grill Posted April 6, 2003 Share Posted April 6, 2003 I was thinking that using a Blue 'N Gold Singh Ray Polarizer could possibly give some very nice effects for bird photography with long teles. The obvious downside is the light loss necessitating a slower shutter speed (as an aside, Singh Ray is soon to come out with an updated version which will sport less light loss). But I think its use still might be possible as you would be using it to make the light look warmer and 'earlier in the day'. Thus it might be used at a time when a faster shutter speed could be used anyway. Also, maybe using it with resting or slower moving waterfowl. The biggest pain might well be using it as a drop in filter as I would think you would need to screw it into the filter holder, hold it up to your eye, turn until you get the effect you want and then drop it in...all before shooting. Just wondering if anyone has tried using these in long teles for nature/wildlife/bird photos. Link to comment Share on other sites More sharing options...
pen name above Posted April 11, 2003 Share Posted April 11, 2003 Howard, Interesting thought. However the technical limitations may precludethis. My 300mm lens has a 82mm filter front. Neither Cokin's system nor Singh-Rays work well at full apertures (which are usually required) for the light loss, as well as the fast moving object of nature. Unless you have a compact zoom with a 300mm f5.6 end, with a filter thread of 58mm or something, it would be hard to fit a Singh-Ray on. At f5.6, you'll already starting to battle with light-loss, and slowing of shutter speeds. Even using 1600 film, shutter speeds can just about be handheld in some lighting conditions. So - Photoshop?

howard_grill Posted April 11, 2003 Author Share Posted April 11, 2003 I was actually referring to the possibility of using it as a 52mm screw in filter with the Canon adaptor as a drop in rear filter on their long telephotos. Anyone try it? Link to comment Share on other sites More sharing options...
hique Posted April 12, 2003 Share Posted April 12, 2003 The idea of getting warmer light is nice, but you can use a warming filter instead. You don't need a gold and blue polarizer for bird photography. Only if you really want a polarizer, but I don't see the point. A warming filter seems nice, less light loss.

ross_geredien1 Posted April 15, 2003 Share Posted April 15, 2003 Polarizers are rarely, if ever needed for Bird Photography. The practical limitations far outweigh the aesthetic benefits that can be attained. The best way to maximize the effects that you desire are to shoot during early morning and late evening hours when the light is warmest and contrast is at its lowest. Polarizers are often unsuitable at these hours anyway, when the sun is low in the sky, and preferably behind you so that you can shoot the bird with frontal lighting. Since polarizers only work perpendicular angles to the sun's rays, they would not be suitable when bird photography is at its best. They can be used during mid-day sunlight, but these conditions are not desireable for birds. Landscapes, sometimes, when you want those blue skies to pop, but not for birds.
