LOL - Recty

Hmmm ok.... The few times I have used a polarizer on my other lenses it can pull the some definition of the from the clouds and bring out the blue from the sky. .

Yeah, it will do that. Maybe it was a bad example picture. What you saw was the Polarizer darkening the blue in the background or partially clear areas. It won't do anything to save the clouds, only a lower exposure will do that. You're right though, it will help in some situations. Still, bracketing will be more effective IMO. Doing it automated may or may not work if your hand holding.

I guess I will try AEB since I will be hand holding. If nothing else, I will just try to find a happy medium between the two exposure levels and adjust in LR from there.

Recty - do you even have a tank setup anymore? Thought that you sold it.

 

[Recty]

Yes, I have a small tank running with just some fish and live rocks, no corals. It's a 38g, just enough to keep me in the hobby, not enough to take a lot of time to keep going.

Thanks for all the great discussion. I have an inexpensive polarized filter on one of my lenses so I think I should take it off. Those of you who use a nice filter on a regular bases can you link me a page with what you are talking about, is that possible?

Here you go. I could give you a ton of examples of shots "with the polarizer" but I can't give you with/without comparisons because I almost never take it off. That said, it's not enough to just have it installed. Its effect needs to be adjusted every time you change the composition.

Without the polarizer, on this shot, there was only a very faint reflection visible on the water. It clearly made this image:

nice, yeah i need to learn how to use it. But, should I get one that's a bit more "quality"?

 

[BlueCorn]

I tell my students to buy the best they can afford.

B+W, Heliopan and Hoya Pro are all good quality. Avoid the non-pro Hoya models as they use a really weak snap-ring design that comes apart very easily. It can be put back together simply enough, but it's a pain in the butt.

 

[Mandragen]

can I have an example of GND

 

[BlueCorn]

Sure, same shot. :lol:

This one too, the top half is several stops brighter than the rest of the scene. Without the GND, it'd been impossible to capture this scene with a single exposure; i.e. you could also do it using HDR or a manual blending of two exposures. I just prefer to get it as close to right in camera with a single frame.

Cheers

There are examples on the right that show what it does.
