The first sun light at Hallingskarvet this morning, just when I ate breakfast.

Nice view for a breakfast

A less inspiring view. The calendar insists that we are now in spring.

The calendar usually has it about right

Must be some serious methane production in that pond?

Morning of the diffused sun.

Nice Dalmatian ground.

I went for a walk in the uMhlanga village this morning, and met these two friendly guys who insisted that I take their picture.
Nikon D90 + AF Nikkor 50mm f/1.8D.

One of my recurring subjects -- a badly cut silver birch on a forest clearing. Done it so many times with different results every time.

Here an IR interpretation with my newly acquired AFS Zoom-Nikkor 80-200mm f/2.8 ED D which I puchased after having used Paco's AF D on my recent Spanish meet-up with him. The later lens is very good for IR, but alas won't focus by AF on my Z5 or Z6 modified cameras. That makes using it a little awkward thus I had hoped the AFS version would keep the good IR rendition and offer decent AF. It does to a large extent, however unlike the previous 'D' version, therre is some vignetting in IR. Not that bothersome and I probably can live with this small drawback.

I like the bluish color and 3-D rendition perfect for this bleak winter scene.

It is surprising to know that the AF-D 80-200 f2.8 zoom for FX format vignettes such noticeably even on this frame apparently with its both sides trimmed.

[Birna Rørslett]

I'm surprised as well. This was wide-open at f/2.8. The frame is trimmed on either side, as you surmised.

Do note this is the AFS, not AF D, version. Paco had the latter and it behaved differently.

I had seen the pattern on several ponds in the area. Thanks for telling me the cause!

A much prettier spring morning. Clear sky, fresh snow and -10°C......

Methane is the common end result from decomposition of organic matter in water, when oxygen levels go low in winter. Depending on the surface ice qualities and thickness, the methane is either trapped as bubble(s) in the ice, or burst through like a small explosion; in the latter case making the characteristic pattern of rays branching out from a centre. Like this example shown below.

Always walk carefully on, or better avoid, ice showing signs of methane production as the ice might break -- I can attest to this happens easily and the experience is chilling
