Dec 19 - One Year on Trek Lens

Yerkes Observatory located on the shore of Lake Geneva, Wisconsin, is the home to the world's largest refracting 40-inch/102cm telescope, plus another 40-inch/102cm called the "41-inch" telescope, and a 24-inch (61cm) also several smaller scopes.

It was founded in 1897 by the University of Chicago and today is still a research and educational center. The observatory building has very ornate masonry with Gargoyles, Grotesques, sculptures, and other fine details typical of buildings built in this era. This image of this shell-arch was taken on the northwest corner of the building on a bright, partly cloudy day.

Shot in RAW with a polarizer, I did basic processing in PS-RAW for color temperature balance, clarity, and a slight lens distortion correction importing the result into PS.

Due to the upward angle this shot was taken, I made a perspective correction using PS Transform in the Skew mode to straighten the vertical lines without seriously distorting the image. Used NIK Dfine for noise reduction and Sharpener Pro. Then still in the color mode using Nik HDR (single-image), added some subtle HDR treatment to create an artisitc effect. In the next layer processed the image in Nik Silver Efex using the variety of tools/filters there plus adding a slight selenium tone to this monochrome layer. Saved this work then cropped to this tighter composition.

I posted another image of the Yerkes Obseratory Winged Lion previously on TL.

Also, I have two different images of the Yerkes Observatory building on my Trek Earth site:

Yerkes Observatory - South View

Yerkes Observatory - Main Dome

HI Larry...
This is very nice image of Yerkes Observatory-Shell Detail in this shot...I like the excellent focus and light. TFS

What a wonderful piece of artwork with amazing architecture, Larry!

The sharpness and POV are excellent, and focus is very well maintained in this B/W shot.
The DOF is amazing, and natural light does make this work so special in its appeal.
Well done!

Kind regards,

Hi Larry
Splendid artistic details in this long focal capture
Beautiful sharpness and resolution

Such an intricate art work and very nicely captured. Thanks for the valuable information. Trying to imagine this in color, I think the B&W presentation is better. Good dof with nice contrast. Well done, tfs.

Interesting artwork on the observatory with intricate detail on
the patterns and gargoyles.
B/w feature brings out the sharpness of the patterns well.
PP work and the angle correction work well here.

Hi Larry! Beautiful capture with great details and sharpness. Regards Csabi

Such a fine capture here stunning detail and focus on this amazing architecture.
Seems like there are so many great photo ops in WI, including this.
I can almost feel the texture of this stone architecture. Wonderful lighting and crop creating a very unique composition. Very nicely done,


Lovely photo, you've made the architectural details really pop, and I like the aspect ratio to which you've cropped it.


The sharpness is the first thing I noticed and it that alone really brought me into the image and made me look closer to see all the dragons and precise designs of the building. The contrast is spot on and I think b/w really works for an architectural piece like this. Nice shot!
