Dear all,
I am spending almost two hours per day sitting in a train. Luckily I use my camera(film) and I still keep shooting.
Some examples below: (well those two do not depict fully the problem, but on the first image you would be able to see some reflections, top-center between the leafs)






One of the thinks that limits me somehow are the windows reflections, where the indoor lamps become visible on the window.
Would a polarizer kill those? As my minolta x-700 measures through the lens I guess it will "automatically" adjust the exposure.

Would that be right?
Regards
Alex

Yes exactly.
There are tons of sample pics and videos on the net
For example http://www.youtube.com/watch?v=EgWB-yad7w0

But be sure not to buy a crappy one, there are HUGE differences in strength of effect and quality between the different filters.

I think Cokin has the the cheapest well usable ones

use a linear polarizer for best results. Circular ones are it bit 'general' and only move a bit of the reflections.

Linear polarizers allegedly interfere with autofocus but I've never had a problem. With the X700 its no problem at all. The camera will compensate automatically.

If you can't find a linear polarizer, get a variable ND filter and unscrew the front element (there are two) and smash out the rear element, clean it up and screw the front back again. These filters have two linear polarizers working against each other.

Hi,
this is the most important advice I ever got! I have a panasonic one.. but I am not sure how good it is. Few questions though:
a. Polarizes does not look to have much effect on partialy obscured by clouds sun
b. Can it be stacked with other filters? Like UV filters and graduated filters.
c. Is polarizer useful is black and white photography or not?
d. can you give me an ebay link for a linear polarizer from ebay? I will just buy it

Regards
Alex

no problem stacking them.

just search for a 'linear polarizer' there are many used ones available. New ones made by Lee tend to cost about €200

Yes, it will have the same effect on reflections as in colour. For getting more contrast between clouds and blue sky a polarizer will work as well, but a yellow/orange filter may be more practical.
