The work is excellent and I will shop here for new wallpapers for many years to come.

Many thanks.

Really, who are friends to quibble over a few measly orders of magnitude, eh? —Jeffrey

Please don’t fry them with your 475 GHz microwaves.

475 GHz is a frequency of visible light, in the deep reds. —Jeffrey

What issues are you having with it? It doesn’t work bi-directionally, so when looking through it while it’s not on the camera, be sure to have it facing the correct way.

When the rotation of the filter matches the polarization of the light, that light is blocked (or, at least, attenuated). Some kinds of reflection are partially or greatly polarized… those from water, glass, and plastics tend to be polarized, and as such, can be reduced by the polarizer if its rotated properly. Reflections from metal are generally not polarized, so it’ll have no special effect on them.

Thanks for the kind words about the post — I’ll have to try to use the black more often…. —Jeffrey

There’s something very appealing also about ‘Orange and Green… and Bare and Blue’.

The only one that doesn’t do much for me is the second: sorry, but I don’t like the sun so near-central, or the flare spot, or the way the leaves on the left have turned into a red mush – I think I’d have tried to hold focus on them, or crop most of them off. But what a challenging shot to attempt!

All our autumn colour has long gone, now, we’re into the season of bare twigs and raindrops.

I feel so sorry for you having all these distractions to hand. When do you get any work done?
