Shooting conditions
Image captured in the amphibians and reptiles section of the Ecomuseum. I was there with Luc, who has already posted great photos of some of the reptiles and amphibians living there, like this one and that one.
Flexible rubber lens hood resting very tightly on the aquarium front window to gain stability (shooting without the flash at a slow shutter speed; I wanted to keep the ISO as low as possible).
ISO 200
Focal length: 54 mm
Captured in RAW format
Post-processing (Photoshop Elements 3):
At the file opening from RAW:
Adjustment to colder color temperatures
After file opening:
Cropping
Levels adjustment
Highlights/shadows adjustment
Unsharp mask
Built-in white frame/border (not a separate layer)
Text layer
Use of the built-in Reduce Noise filter
Conversion to JPEG at TN size
Subject:
The Map Turtle (Graptemys geographica) is named after the pattern on its shell that reminds of contour lines on topographic maps. The male is much smaller than the female, its shell being no longer than 7 inches, whereas the shell of the female can be up to 11 inches long.
In summer, this species can travel up to 6 km (4 miles) in one day, and a lot more in spring and fall. At Lake Champlain, in Southern Quebec (Canada), Map Turtles have been observed making trips over 15 km (9 miles) long between their winter quarters and their summer habitat.
The diet of this turtle is made up mostly of aquatic molluscs, in particular snails, but also of crayfish, insects and sometimes worms, fish and plants.
Adults are sometimes the prey of the River Otter, the Racoon and other mammals as well as large fish and herons. Eggs are in great risk of predation by the Striped Skunk.
The Map Turtle has been designated a rare species in Quebec.

I hope you find some interest in this posting. Please do not hesitate to critic, as I’m low on my learning curve! |

In Photoshop Elements, adjusted the midtone slightly to decrease the lightness in the image.
Hue/sat. adjusted the yellow and red colors.

Serge,
J'ai fait un tas de manipulations avec Photoshop CS. J'ai joué avec les couleurs; j'ai ajouté le nom scientifique de la tortue; j'ai joué avec le sharpen et NeatImage. Bref, je me suis amusez beaucoup, merci. J'espère que tu aimes le résultat. J'ai été tenté de rajouter les milimètres manquant de la réflection...
Amicalement,
Luc |
