Thanks a lot JimJimKasson wrote:
Excellent shot. I haven't been in Zurich in 30 years, but went there a lot in the 80s when I worked for IBM. I thought at first that maybe if I zoomed in I could pick out one of my favorite restaurants, Kronenhalle, but I see this is one bridge upstream from the one I thought it was.
Very cool image - interesting and unusual... a new genre perhaps?It's not a Zx shot, but here's one I did a few days ago using cross-polarization.I like that idea. The lighting needs other work as well. I really like the spectrum of this lamp (I got it for print viewing). But it's a linear stick so you might say that those shadows have astigmatism.Consider cross-polarization to mitigate those specular highlights.
This pic was a technical exercise: my second trial of the focus stacking feature on the Z. It's not anywhere near as civilized in that function as a GFX but it seems to get the job done. And the Helicon software is a joy.

GFX 50S, 120 mm macro, 2 Aputure 120d lights, 2 Bowens-mount Fresnel lenses, Rosco polarizing gels in front of the Fresnel lenses, 77 mm polarizer on lens using step-up ring. 50 shots using focus bracketing, step size 4, stacked in Helicon Focus.

My first reaction was, "Wait, what? We've all been using circular polarizers on digital cameras."For this type of shots I use a linear polarizer on the lens, shots come out a bit sharper.

There's nothing in photography that's completely novel, at least for me. This is a combination of flower photography -- a subject so old and common that some people say just don't do it -- and ice forms. I was introduced to ice forms by Ryuijie,a new genre perhaps?

I'm using linear polarizers on many dSLRs too. They are not interfering with AF as much as Internet suggestsMy first reaction was, "Wait, what? We've all been using circular polarizers on digital cameras."For this type of shots I use a linear polarizer on the lens, shots come out a bit sharper.
Upon reflection (pardon the pun), it made sense to me. Mirrorless cameras don't have semi-reflective mirrors that steal light, with a preference about the direction of polarization, away from the upstream optical paths of AF or metering systems.
As it turns out, today the only polarizers I own are circulars. Actually, when I flip them around they act as linears. Sure enough, nothing changes in either the autofocusing or metering results* on my Z7 in any orientation of the filter. So it looks like linear polarizers would be acceptable for use on this camera.
(* the metering target was a matte-surface paper illuminated by virtually a hemisphere of diffuse light)
