ok, net jacked up and i started this damn thread and the file was deleted.

SO, would a polarizing filter help with the overexposure in this pic? I've never gotten the chance to work with one before

Not really. It can make colors richer in some cases, though it can cause an uneven sky effect that some people hate and others love.

You'd need some kind of graduated filter for that.

Thanks!

your best bet for this picture would be HDR (IF YOU CAN DO IT PROPERLY) or expose less and bring up the shadows.

True. Make sure you follow this one's advice and do it properly. Make it look natural.

The graduated filter is good, but obviously works best on straight horizons and in this case the buildings would be altered too. You can get soft and hard graduations that help somewhat in getting the right look, but (a natural looking) HDR would likely work best in this case.

I'm trying to keep the post-shot photo manipulation to a minimum.

also, did a bit of reading up on graduated filters. Is there anything that requires less setup (more a P&S style filter) the sites i was reading up from describe and show a graduated filter being something youd need a tripod for

This is not true. Probably.

It depends on where the sun is, but in the best case scenario, the polarizer cuts out about half of the light from the sky. The light reflecting off the foreground items will still be about the same, however (more or less. Some of that will be cut out, too, but not nearly so much as in the raw sky).

But hey, you don't have to take my word for it. Have some proof! Here's a picture I took back in May. I had my polarizing filter on, but turned to minimum polarization in this shot. To keep the sky from being blown out, I had to use a shutter speed that left the ferris wheel looking kind of dingy and shadowed.

Now, here's the same scene mere seconds later, with a half-twist of my polarizing filter. Note that the sky looks about the same, but the ferris wheel is much brighter and sparklier. That's because the polarizer cut out a huge amount of sunlight coming from the sky, but not a similar amount of light reflected off of the ferris wheel.

You could get a Cokin/Kood style filter holder fairly cheaply. Once the filter is in place you can use it hand held as normal.
>> ac !!VPzQAxYPAMA
Now the "probably" part is that this only works if the sun is at the correct angle for the polarizer to be at its max effectiveness. In some directions, the polarizer does nothing. If you're at the right angle from the sun, though, the polarizer can do some magical things.

>>91934-thank you. I'll pick one up for christmas while verything is cheap

ac -thank you as well. I'll be picking up a polarizer too.

If you are going to by a screw-on filter, don't buy the official Canon one as it is a rip-off. Buy a Hoya blue line one. They are good value and balance the performance-price well.

Make sure that it is marked as a CIRCULAR polarizing filter. Not a linear one to make sure it works okay with your digital camera's features.

a problem with polarizing filters vs HDR or exposing differently is sometimes you want the reflections coming off of an object.

Thank you very much.

Both of the photos are from Ft. Apache near Globe Arizona

the best way to help with the overexposure in this photo is TO NOT SHOOT INTO THE SUN. you don't need a polarizing filter, or HDR, you just need to be there about 10 hours earlier in the morning, with the sun at your back.

yeah, the timing wasnt anything I could control.
