When I bring up your profile page it lists 77 photos as being Featured, but when I click on the Featured icon I can see only 17 of them (and the Featured section lists the count as 17). Your total Photos is listed as 48, and I can see them all. As I scroll through Galleries, I see 13 galleries and they list a total of 47 photos. I can see the Moroccan Dunes photo (which I'm assuming is the one you just uploaded) in all three sections (Featured, Photos, and Galleries). As for Trending photos, I see Moroccan Dunes on the last page, but none of your other shots. I assume there is a time limit for Trending photos - maybe "stale" photos that were uploaded more than 30 days ago are removed from Trending. Hope this helps. I'm using a Windows 10 laptop with the latest Firefox.

Steve, it really isn't possible to see detail on Mars with your lens. What you're getting are out of focus images of what is nearly a point source, and "details" are most likely atmospheric effects. With Mars being rather low in the sky for you, these effects are worsened - you are looking through at least three air masses (three times the amount of air compared to looking straight up) when you look at Mars. People who are getting nice images of Mars, including surface details, are using longer focal lengths and image stacking (often thousands of images) to wring out details. See the Solar System Imaging and Processing forum on Cloudy Nights. Cloudy Nights Forums

The Sunny 16 rule applies to terrestrial scenes, and it needs to be adjusted for something like Mars, which is farther from the light source (the Sun) than the Earth. Mars receives a little less than half the sunlight as does Earth. In addition, the light from Mars needs to pass through our entire atmosphere, which scatters and absorbs light, further diminishing its brightness. For a photo of Mars, Sunny 16 may need to be modified to Sunny 9.5 or even Sunny 8.

It's deceiving in its simplicity. Very striking. -
Wow, imagine that!

Granted, Mars is near opposition and appears bigger than it usually does, but it's still mighty small at only 24 arcseconds. With a 105 mm lens, it would make an image about 12 micrometers across, or about 3 pixels on the D7100 sensor. Being orange, it should also show some color. In Minnesota, Mars is only going to get 20 degrees or so above the southern horizon, so there may be some atmospheric degradation of the image. I suspect we are seeing either a focusing problem, or an object that is not Mars.

It's like a sleepy eyelid closing on an autumnal scene, getting ready for winter's hibernation. -
Without the bottom quarter or so, this would be much more abstract, a collage of shapes and primary colors. But the bottom of the photo brings us back to the reality of concrete, sewers, tires, asphalt. I like that division between the vivid, dynamic shapes, and the gray dullness of the paved urban environment. -
I love the Penrose tiling, and I'm glad to see it being used in architecture. I toyed with the idea of tiling a bathroom like this, but because tile shops don't sell Penrose tiles, I would have had to cut them all myself, so it remains a pipe dream. Showing just part of the building and the advertising adds to the abstraction. Excellent work. The spire on the right just looks impossibly tall and narrow. I'd like to visit this place someday. In the meantime, I'm enjoying your virtual tour, Drew. -
Just to be clear, I'm sure Jack's photo complies with PN's Terms, and here in the States it would be "fair use" under copyright laws. I see no problem there. There is obviously no claim by Jack that he made the woodcut, and there is no commercial use, nor harm to the artist. The question I asked in my first post is one I've found intriguing for years, and seeing Jack's photo just brought it up in my mind again. It was a somewhat tangential thought. Holger, I think that sculptures in public places can be great photographic subjects. I take photos of them with zero guilt, because like you, I'm not claiming I made the sculpture, nor is my purpose commercial in any way. -
Drew, many thanks for your comment here, and for all your recent comments on my photos. I appreciate them very much. -
To me this is a somewhat humorous depiction of the "tunnel and light" experience some people have reported during a near-death experience. Instead of a tunnel, here is a hallway, and the bright light comes from the kitchen. The funny part is that instead of floating peacefully down the tunnel toward the warm and all-encompassing light, your brother has turned his back on it to get in one last putt. A sort of parting shot, a shot directed at you. I really like this photo, Jack.
