Orkney Islands-Storm over Hoy

Filed under: Landscape, Orkney Isles — Harold Stiver @ 7:50 pm

Storm over Hoy

The following series of images were taken from Warbeth Beach on the main island of the Orkneys. We are looking towards the island of Hoy as a furious storm boils up and clears. I walked along the beach and took photos with various foreground elements I thought were interesting.

The shout of spring-Redbud

Filed under: Landscape, Long Point — Harold Stiver @ 7:10 pm

Redbud

Signs of spring creep in at a slow pace, the birds start to trickle back, trees to leaf, and the grass becomes greener. Suddenly one day, it seems to bust forth with a rush and the main sign is the flowering shrubs. Forsythia first, and later lilacs and flowering dogwood. My favorite is the Redbud. This specimen has toppled in some long ago wind but still brings forth these gorgeous cascades of color.

Photoshop Tutorial-Recovering blown highlights

Filed under: Photoshop Tutorial, Processing Tips — Harold Stiver @ 2:10 pm

This Photoshop technique allows you to add highlight information to your image. It is useful for images such as landscapes where portions of the sky have blown. Note you need an image which was shot in RAW to use this technique.

In our example, the portion of sky in front of the storm has some rose portions and then some blue sky, which can be seen when the exposure is reduced. We want a properly exposed image which incorporates this information.

1. Do an initial RAW conversion of your file allowing the highlights to remain blown but with the balance of the image in the right exposure. We’ll call this the light image.

Great Blue Heron eats a large catfish

Filed under: Birds — Harold Stiver @ 6:55 pm

Great Blue Heron with a catfish

It can be amazing to watch a Great Blue Heron catch and eat a large fish. After catching the fish with a lightning strike, it brought it to a shallow spot where it proceeded to strike it repeatedly, impaling it each time. No doubt it wanted to make sure there would be no movement of the victim when swallowed and a possibility of a severe injury from the fishes fin spines. It would also serve to help digest the prey, a formidable project involving masses of scales and bones.

Dunlin-Fattening up on the way north

Filed under: Birds, Point Pelee — Harold Stiver @ 11:43 pm

Dunlin

I came across this ball-shaped Dunlin, (Calidris alpina) at Point Pelee. It was among a group of about 20 others who were feeding while making their way to the tundra of the far north to breed. But this Dunlin was not like the typical Dunlin like the image below. It kept itself hunched up in a ball like this but otherwise acted just like the others. Perhaps it had eggs ready to lay, or was ill, but it certainly looked different. (more…)

Wood Thrush in the mist

Filed under: Conservation, Point Pelee — Harold Stiver @ 10:52 pm

Wood Thrush

A misty morning at Point Pelee produced this cooperative Wood Thrush. One of the finest singers, it does lovely flute like variations with an introduction and a counterpoint.

It breeds in the deep forest of eastern North America and it’s numbers are in decline due to loss of habitant, and parasitism by Brown-headed Cowbird.
