I got a circular polarizing filter. I've been wanting one for ages. I'd love to know if anyone has any advice about them. I've been rummaging around youtube and found some incredibly ridiculous stuff that I know, right off the bat, is junk advice (everyone's an 'expert'.) I, also, found some helpful advice. So, this is the first image that I've taken using it. Indeed, it took out al lot of the reflection and made the detail easier to see. Actually, though, on this, particular teacup, I like the reflections - duh!   Because of some of very dubious advice, I'm wondering what effect the direction of the light will have on the image when using the CPL. Also, how does it technically work - I can't figure it out. I mean, I know how to use it but I don't get how twisting it makes it go darker. er, magic? Thanks for any help!  |

Hi Katy, I have never used one for indoor shots. But ii you go outside, they work best with the light source (normally the sun) is at 90 degrees to the view you want to take, then by turning the filter you should see a good difference in the sky.

I just totally don't get why it gets darker when I turn it. It's probably obvious buy I just don't get it. I can use it - I just don't know how it turns darker - the WHOLE thing turns darker. Don't get it. Nope!  Actually, I found the chapter In Light: science and magic. I read it ages ago but need to review. I simply want to experiment - and on more than just the sky and landscape.  |

Hi Katy! Not a cpl expert but I have been using one lately. So far just outdoors. And as Barry pointed out, they work best at 90 degrees. I can set it so the sky appears a little darker/bluer or lighter/whiter. I have found that they are excellent with water shots in that it takes the reflection and somehow makes it so you can see through the water/reflection. From your photo it looks like the lower right side of the image is darker than the rest. Might be that the darkest part of the filter is there. Go outside, frame the sky with the sun to your right or your left and turn the filter and watch how it changes thew color of the sky.When you see that the top(half) of the sky is darker look at where the filter is on your lens. Luckily certain parts of the writting on my filter lined up with certain parts of writting on my lens. So thats where I start if I want to darken/bluer my skies. You can do the reverse( lower half of framed image). Hope this helps. There are a few of my newer shots that I posted on flickr, using a cpl.Havent done any indoor ,although I think I might have a go at it.

Thank you, Kit! Those were the 'open sesame' to the cave of wonders that is the information on the internet. I was googling the wrong words. Now, just taking a brief look, I do see! I'll have to read later, though, when my cold isn't clogging up my head - it does stretch the old noodle. |
