Taken in the last week, these images were obtained with the Sony A900, the Steinheil Cassar-S at f/16, and the Baader U2 filter. Display intent is BGR.

 

"Pond near Lake Darling:"

 

 

"Fishing by the Channel:"

 

 

The young fisherman's cap was red. One would expect it to show up black, but it presents as pale cyan. Red dye is notorious for fading with time. If this dye absorbs relatively little UV, does that mean it might be more fade-resistant? The reddish tinge on the old, withered water vegetation is also noteworthy.

 

"Vickerman Barn:"

 

 

The reddish coloration of the freshly plowed soil is interesting here.

Clark, Very nice photos indeed!

What does “BGR” mean in this context (since there is also UV involved)? Did you flip the red and blue channels of UV photos?

[Andy Perrin]

Stefano- yes, that’s what he does. It is his usual procedure.

Thanks, now I know it. I didn't notice it is his usual procedure.

I like the barn photo - red barn, reddish soil.

The second photo is actually from Hubbard County, but I did not want to be bothered with a separate post. Tech details as above.

 

 

 

For good measure, here is an IR+UV image of the first structure, taken with a #403 filter:

 

 

This last type of image is more IR than UV, but was popular a few years ago. I don't see so many of these any more.

This amusing bit of folk kitsch was inspired by the discovery of the Kensington Runestone, a controversial artifact unearthed nearby in the 1880s that has inspired some fringe historical theories. (Sony A900; Kuribayashi 35; Baader U2; display intent BGR)

 

 

You have to admit that Ole does not look very blond in UV! The winged helmet is also a hilarious anachronism, but locals love it.

Fascinating history.

We have Norumbega Tower here in Massachusetts, where the Vikings landed on the Charles River! (No, not really.) It was built by a wealthy industrialist who invented baking powder, Ebers Horsford.

Playing with the Olympus 35RD and Lomochrome Turquoise film (which natively does BGR-->RGB color scrambling,) I slapped a Baader filter on at the end and took a shot or two at the old Spruce Hill Swedish Church. The result was cyan monochromes rather than the conventional yellow, in line with what might be expected with this film. I kept all three channels in the workup and there may be a hint of chromaticity here, or perhaps it is just tint gradients--I am not sure.

y?

 

You can see that there are no UV guard panes on the windows (which I already knew from previous experience.)
