From Kärnten - to Ivan.

(9375) [2008-07-31 09:04:40]

This one is dedicated to one of our top naturalists and nature photographers here on TN, to Ivan Kruys (Argus).

The picture was taken from close distance - approx. 30cm, and therefore with reasonably good details:

Oeneis glacialis,
Alpine Grayling,
Gletscherfalter.

That lonesome specimen was seen at an elevation as low as 1500m - and no glaciers around.

Location: Mussen, Lesachtal, Carinthia, Austria, near the village of Kötschach-Mauthen. These remote alpine pastures were cleared from forests in medieval times, and are still maintained by cutting grass and harvesting hay every second year in alternating patches. There is an immense variety of plants and invertebrates up there.

Camera: SONY DSC-H5, 3072 x 2304 pixel, sRGB, 16mm macro (= 96mm at 35mm SLR), F/8, 1/125sec., ISO-125; handheld, no flash; 09.06.2007, 13:34.

Postwork: Photoshop Elements, slightly cropped, downsized to web presentation, brightness, contrast and saturation adjusted.

Hope you enjoy.

The Gregarious Toad (12) *
Dillinger

(121)

contrast reduced on BG

(9375) [2008-07-31 04:56:34] [1]

Trying to add a bit more attention to the toad by reducing the hard contrast of BG.

1) Selecting color from somewhere in the midrange of BG - here it happened to be:
(HSB) Hue 35°, Saturation 60%, Brightness 59%
(RGB) Red 150, Green 113, Blue 60

2) applying that color by transparent spraypaint tool (coverage 5% to 8%, r = 65) on darkest parts of BG, and also on some of the brightest parts - in order to reduce the dominance of the BG.

3) Lighting up the deep shadow under the toad's fingers the same way - in order to get out some more details there.

4) Saturation of green reduced by -40% (in order to reduce the dominance of those leaves in the BG as well - if intended).

Hope you enjoy.

The location.

(9375) [2008-07-28 13:25:44]

The location: the path leading to Hochjochferner glacier near the village of Vent, Oetztal, Tyrol. Taken at an elevation of 2630m a.s.l., 2008 07 19, 14:57.

By the way: The rapid drawback of Alpine glaciers may be well be seen here. The straight line in the middle of the slope to the left that looks like a path actually is the the edge of the glacier's moraine showing the glacier's level at around 1850. The thickness of the ice layer has clearly reduced by at least one hundred meters, and the extension of length by more than one kilometre since then. And melting down goes on every summer with an even increased speed since about 1990.

Satyrium spini,
same day, same location, close approach.

The long soft wingtails may be seen better here. They were in peculiar slow constant motion.

Argynnis paphia L.
The Female.

Silver washed Fritillary
Kaisermantel, Silberstrich

The female A. paphia has a significantly different appearance. One may even mistake the female for a different species. It does not have the male's broad dark veins on the forewings, all the dark spots however are more extended. The wing colour is not a bright orange yellow, it is more or less shaded and tends towards a greenish hue.

This picture was taken at the same day at the same location: Lago d’Idro in northern Italy August 5, 2004.

Camera: Minolta Dimage 7Hi, with integrated tele-zoom and macro, no flash.

The Underside.

(9375) [2008-06-20 07:23:58]

To verify the identification of members of the Lycaenidae family, a documentation of the underside of wings very often is necessary. This Argus Blue was quite cooperative.

The camera:
SONY DSC-H5, 3072 x 2304 pixel, sRGB, 17mm macro-zoom setting (equiv. 110mm at conventional 35mm SLR), F/5, 1/320 sec., ISO-125; -0.3 bias, no tripod, no flash; 18.05.2008, 11:57.

Postwork:
Photoshop Elements, substantially cropped, downsized to the web, selectively resharpened, levels slightly adjusted.

Wings closed, and both the butterfly and me fighting against the strong wind on that day.

The camera: SONY DSC-H5, 3072 x 2304 pixel, sRGB, 15mm macro-zoom setting (equiv. 90mm at conventional 35mm SLR), F/4, 1/200 sec., ISO-125, -0.3 bias; no tripod, no flash; 18.05.2008, 14:06.

Wolf Fish (15)

Colour tint neutralized.

(9375) [2008-05-23 13:05:35] [2]

The orange colour tint seems to have been caused by artificial light and/or a tinted glass. I tried to compensate that by applying Photoshop Elements tint removal tool. Then there was a 20% increase of contrast, selective noise reduction on the background, and a selective application of sharpening filter on the wolf fish.
With thanks, and best regards.
