I have revisited the images I took last week at Glenridding of Ulswater in moonlight. I sifted through the 50 odd images I took and settled for one of the last which was taken with a full, unobscured moon.
The details are as before, D200 (normal, not IR or UV), Nikkor 20mm f2.8, @ f2.8 with an 8 second exposure, Hi-ISO NR, normal; long exposure NR, ON.
With my larger monitor and easier working I have been able to have a better look at the fringing.
Here is my best effort at processing the image: I am still unsure about the tint towards sepia, but reducing the saturation seems to detract from the effect?
I am very pleased with it, If I had realised how good the D200 was going to handle the extremely difficult lighting I would have gone home for it at the previous full moon. The water was as flat as a mirror and the reflections were perfect, but that's life as they say.
The fringing. It appears to come in three colours depending on the orientation of the contrast junction with which it is associated. Horizontal seems to be grey, vertical on the left seems to be magenta and to the right, cyan.
These screen shots have been taken in Photoshop at 400% I have manually remove much of the fringing in the image above, I tried using the CA removal tool in Lightroom but it didn't do anything, I think there is one in Ps but I couldn't find it.
The skyline of the large mountain:
The branches of the nearby tree:
The cyan and magenta fringing can be clearly seen in this screenshot. The fringing seems to change to grey on the horizontal branches. Very strange, I have removed most of the cyan and magenta fringing but the grey was much harder and where the branches were tightly packed I gave up!
