Good Day Flexers. I'm just revisiting the classics of the photography, learned long ago. I'm not very fond of filters but the polarizing filter is a "must have", I suppose. In the time of the Film Era, I had one in my bag along with "tobacco", useful for blue landscapes. Now with the "white balance" to be set as needed, these tobacco are obsolete, sold... Of course my "Pola" is Circular, not too sure it would work with the Digilux3 light meter, sin ome article I read, it spoke of the Linear as best choice. To make short a long story, I blew away the dust over the case of 55mm filter and find out an astute Chinese Entrepreneur in Shangai offering a step up 43mm to 55mm for 1.5 Euros (ship&tax included), it took me a Fiver at the local Portuguese Pub to toast the good deal, a pint in hand.... It fits nicely, although this image shows the step up filter loosely set over the CPL filter: http://xavierf.b.free.fr/Temp/cpl/P1010516_dev.jpg Today, sunshine, off the street to try out. Just in front of my home, ideal subject: Without: http://xavierf.b.free.fr/Temp/cpl/L1000951_dev.jpg With the CPL to its max effect: http://xavierf.b.free.fr/Temp/cpl/L1000952_dev.jpg Works fine here I think. --> All reflections are gone but if you see on the right of the image, the black bars of the fence of the house show more details. Another Go, without: http://xavierf.b.free.fr/Temp/cpl/L1000957_dev.jpg With CPL: http://xavierf.b.free.fr/Temp/cpl/L1000958_dev.jpg --> A blueish sky and nicer colors. Images : Digilux3 + 25mm Oly Pancake; first one, Compact with Leica Glass Using the same camera I had shot this with the Angenieux 35 x 2 and a polarizer http://gallery.leica-users.org/v/Phileica/PAW-2009/PAW-2009-Old+Postcard-1090374.jpg.html http://gallery.leica-users.org/d/152767-1/2009-PAW-08-Paysage-Cheminant-10808242.jpg Bluer and nicer IMHO too - yet highlights might be a problem as well as metering. Of course, you will say that God Photoshop or its Demon Silkypix can do equal. That's not my opinion when the filter remove the reflections... Other than that, I tried a Yellow filter (55mm too), used as some may recall, in the days of B&W films, to enhance the sky and the contrast. Er, no interest at all, the White balance system corrects automatically the cast! You surprise me Xavier - I shot hundreds of RAWs that turned out yellow with a yellow filter on the L1 http://gallery.leica-users.org/v/Phileica/Noir+et+Blanc/20080221-P1020557-2.jpg.html http://gallery.leica-users.org/v/Phileica/Noir+et+Blanc/KitzelPfadt-BW-w-s+2-JL.jpg.html And for B&W, a good dose of Hygh Dynamic Range plus fiddling with the curves, it gives a far better result... Silverfast is the way to go for BW from what I see and read from other groups. Plus the fact that the camera has a 'B&W Dynamic', I speak of the Digilux 3 as 'my' camera, of course. But in my opinion, the CPL filter creates a mess with the Autofocus system, may be because it is Circular rather than Linear. Your widsom is much appreciated here :) No experience with the AF as the pola I have only fits my fully manual Angie Keep experimenting Xavier Amitiés Philippe OH, BTW, the car is not mine, it was parked in front of my house, over the street. Have a nice week. #----------------------------------- From : Xavier F. BILLE mail : hot_billexf@xxxxxxxxxxx Maisons Alfort - France
