One and Seven WTC,a NYC subway map,and a train's handrail. I'm back here on my original page. I figured how to get back.Sorry about the runaround..I ran around too :-) You can comment here from now on.Thank you for your patience.Your viewership is much appreciated!
The Sun's axis of rotation varies in relation to the solar North pole over the course of a year. Interesting article in Sky at Night magazine about using freeware programs "Helio" and "Tilting Sun" to measure the tilt and overlay a grid for any solar image taken at a particular time. 0-180 line is true North-South and on the 30th September 2017, the axial tilt (P0) was 25,93 degrees.
There is also variation on the forward tilt of the Sun over the year. You can see more grid lines at the North Pole than the South in this instance. The angle of tilt is given as B0 and varies between plus and minus 7 degrees over the year.
The article also quoted the Mount Wilson Solar Seeing Scale - there was good seeing on the day this image was taken - probably a 4:
4: Sun is sharp for more time than it is fuzzy. Solar granulations visible for most of the time. Limb motion and resolution are in the 1-2 arcsecond range.

Technicians installed two instruments on NASA’s IMAP (Interstellar Mapping and Acceleration Probe) spacecraft on at the Astrotech Space Operations facility near the agency’s Kennedy Space Center in Florida. The work took multiple days and finished on Monday, June 23.
Scheduled to launch this fall, IMAP’s 10 science instruments will monitor space weather and study and map the heliosphere, a vast magnetic bubble surrounding the Sun protecting our solar system from radiation.
Earlier this year, technicians at NASA’s Marshall Space Flight Center in Huntsville, Alabama, conducted thermal testing to see how the spacecraft and payload respond to extreme heat and cold. This followed vibration testing in December 2024, which simulated the launch environment to ensure the safety and integrity of the spacecraft and payload during launch.

Finally finished with school so now I have time to go out.
I'm just trying out some manual tone mapping as an alternative to the usual boring HDR stuff... I like it... it takes considerably longer. However, it is much more flexible!! I'm not quite down with the technique yet unfortunately.

Who shares their images with the world? This map of Flickr activity around the globe starts to give us an answer.
When they're not mapping zombies, Mark Graham and the team at the Oxford Internet Institute, are undertaking even more serious research into the state of the internet - this map is part of that work.
Using Flickr's API, they mapped every geotagged picture on Flickr by downloading the count of photographs in every 0.5 x 0.5 degree latitude-longitude square on the Earth's surface.
As might be expected, the largest concentrations of photographs can be found in some of the world's most populated places.
Images are an important form of knowledge that allow us to develop understandings about our world. Flickr is the world’s most used and most popular public repository of photographs and currently hosts over five billion images. This map reveals the global geographic distribution of geotagged images on the platform, and thus reveals the density of visual representations and locally depicted knowledge of all places on our planet.

One of those mapping things, you know the sort they drop around the countryside so you can find where you are on the map - if you've got the right map.
I'd like this one to be much bigger, like some kind of huge monolith, maybe see what photoshop can do.
As per usual the colours look more like I intended if you check out the full size version
One of the most compelling sights in Jaipur, India is the Jantar Mantar, a Unesco world heritage site. Completed in 1734 by prince Jai Singh II, the founder of the city, it is an astrological observatory. The structures, like the one pictured, are used as instruments to map the heavens, and the world's largest sundial is part of the complex. Photo by Dave.

Data:
The covers of every issue of Time magazine published from 1923 to summer 2009.
Total number of covers: 4535.
The large percentage of the covers included red borders. We cropped these borders and scaled all images to the same size to allow a user see more clearly the temporal patterns across all covers.
----------------------------
Timescale:
1923-2009.
----------------------------
Mapping:
Time covers appear in order of publication (i.e., from 1923 to 2009), arranged in a grid layout (left to right and top to bottom).
----------------------------
Mapping 4535 Time covers into a grid organized by publicatoon date reveals a number of historical patterns. Here are some of them:
Medium: In the 1920s and 1930s Time covers use mostly photography. After 1941, the magazine switches to paintings. In the later decades the photography gradually comes to dominate again. In the 1990s we see emergence of the contemporary software-based visual language which combines manipulated photography, graphic and typographic elements.
Color vs. black and white: The shift from early black and white to full color covers happens gradually, with both types coexisting for many years.
Hue: Distinct “color periods” appear in bands: green, yellow/brown, red/blue, yellow/brown again, yellow, and a lighter yellow/blue in the 2000s.
Brightness: The changes in brightness (the mean of all pixels’ grayscale values for each cover) follow a similar cyclical pattern.
Contrast and Saturation: Both gradually increase throughout the 20th century. However, since the end of the 1990s, this trend is reversed: recent covers have less contrast and less saturation.
Content: Initially most covers are portraits of individuals set against neutral backgrounds. Over time, portrait backgrounds change to feature compositions representing concepts. Later, these two different strategies come to co-exist: portraits return to neutral backgrounds, while concepts are now represented by compositions which may include both objects and people – but not particular individuals.
The visualization also reveals an important “metapattern”: almost all changes are gradual. Each of the new communication strategies emerges slowly over a number of months, years or even decades.
