Volleyball Team Photo

For some reason I read the title as "dream" instead of "team" and thought it was going to be about butts.

Since I have a daughter who plays, I was going to respond with how offensive I thought this comment was.

But then I looked at your website, and realized you have a lot of friends that could hurt me REAL BAD.

So I'll play it safe.


LOL!!!

Not to worry, I usually don't even look at volleyball threads. I saw how long the thread was, and figured it had somehow degenerated into fighting. So, as you can see, I was looking for conflict, not girls in spandex, not that there's anything wrong with that.

CPL == Circular Polarizing Filter. It eliminates glare coming into the lens from certain angles, sorta like polarizing sunglasses. It rotates, so you can dial in the effect to some degree. Used by landscape photographers to eliminate glare in water and from vegetation and such. In some instances, add an insane amount of punch. Could work in this application, but will also eat a stop to a stop and a half of light.

Thanks for the explanation. I was thinking it was some sort of layer and a photoshop thing. The reflection problem I was having was from the two main lights and was the type of reflection similar to if you were shooting into a mirror because of the glossy finish. Do you think it would still work?

No fighting yet but give it some time, anything is possible on POTN. Hope business is going well in the combat sports world.

Thanks. Nice pic, btw.

No worries on my end..... My comment was in total humor...... and thus in total safety!

In my experience, its gonna help some, but perhaps not uniformly. It manages reflections at certain angles, and these angles won't remain constant to the position of the camera. For instance, I have used it shooting interiors to knock down reflections in wood flooring. But I can only recall one occasion where it eliminated all of the glare -- mostly it makes it less severe, easier to photoshop, smaller.

So it might knock down the reflection in a certain part of net, but probably not across the entire length.

Nice work on the photo and the critiques. It'll help with an upcoming project I'm working on.

His reflection problem was off the bleachers. Not the net..

That being the case, so long as its uniformly reflected, a CPL will take care of it. Reflected light is polarized in the same direction. A CPL will either block or allow the passage of polarized light through it. However, that doesnt mean it blocks all reflections. You have to turn the CPL 90° to the polarity of the reflected light.* The practical way of doing this is simply turning the CPL until your reflections vanish. To do this with strobes, it may be trial and error or you may try using some strong modeling lights.

*: Think of it as a rope going through a fence. If you shake a rope up and down through the slats of a picket fence, the motion will have no problem going through. However, if you tried shaking it side to side (or if you could rotate the fence 90°), the slats would then block the motion of the rope from going through to the other side.

Pardon the confusion with regards to the bleachers.

In practical application, the angle of polarity is relative to the lens. If you are using a long focal length, the polarizer will be more effective from margin to margin, as there is relatively little change in angle from margin to margin in the frame. A wide focal length, on the other hand, with its larger field of view, will have more difficulty eliminating the polarized reflection from margin to margin, as the the reflections angle relative to the frame margin changes as you move across the field of view.

Its just math.

Adam and Ty,

Thanks for the excellent info. I actually have a CPL and am going to give this a try next time I am at that gym for photos. Would have never thought to give it a try in an application like this.

Thanks again and have a good week.

Negative sir. Polarization will vary with the change in incident angle between the light source and the reflective surface. In other words, angle of polarity is relative to angle of incidence. Wide angle lenses only exacerbate this problem because they are, by nature, taking in a wider view, and thus are taking in a wider range of incident angles.

While you are right about observed effects when using WA-UWA lenses with a CPL, youre reasoning behind it is faulty. I realize it may be trivial but I never enjoy muddying up the intellectual waters and I try to do my best to provide clarity when possible.

Its just physics.

Won't muddy it, then. You're wrong.
