this is my first try of a 360x180° full spherical panorama
No, I didn't forget to take enough pictures, the white spots in the image are snow...
However, I wanted to upload this image, because I hope someone can help me a little bit.
I use Hugin to add controlpoints and optimize them. If I add more horizontal lines the horizon becomes straight (at least as straight as you can see it in the picture) and the stiching errors become more (and vice versa). Any suggestions how to avoid this?
The second problem seems rather simple, but I didn't manage to solve it: how do you shoot a full spheircal panorama without having your shadow in the image?
BNSF 6427 and CN 5710 westbound on the CN Freeport Subdivision at the East Rockford control point and interlocking (with the Illinois Railway) at CN milepost 85.6 in Rockford, Illinois. Following the CSX buffer car is a unit train of empty ethanol tankers. Just ahead the train is about to duck under the historic 1901 Seminary Street timber-stringer bridge and then cross the Rock River.

CN 5799 and CN 2568 lead an empty ethanol unit train westbound past the Behr Iron and Metal siding and the East Rockford control point and interlocking (with the Illinois Railway, Rockford Division) at milepost 85.60 on the CN Freeport Subdivision in Rockford, Illinois on a cold and overcast early January afternoon.
A survey monument at Coit Tower in San Francisco. January 2009. This monument was placed by the U.S. Coast and Geodetic Survey agency in 1954.
I was about to label this as a benchmark, but that is not correct. Benchmarks are survey monuments of highly precise elevation, used to measure and survey elevation or height above mean sea level. But this is a horizontal control station, used to survey / establish horizontal locations (latitude and longitude, or other systems of x and y coordinates) on the Earth's surface.
This disk station is named "PLAZA" and "HT3075". You can get detailed data on this survey marker from NOAA's National Geodetic Survey data. Try this link: www.ngs.noaa.gov/cgi-bin/ds_mark.prl?PidBox=HT3075
Looking at the data sheet may give you some idea of how this station is used in mapping. From this point, angles to other visible survey markers are precisely measured with survey equipment. Through triangulation and other mathematical calculations, precise locations of the network of control points is determined. The datasheet shows other nearby survey points that were used in this way, including the Alcatraz lighthouse, the north and south piers of the Golden Gate Bridge, points on the Bay Bridge and Treasure Island, a point on the Ferry Building, a beacon on a breakwater in Berkeley, etc.

Grain cars zoom westward on the CN North Division, Freeport Subdivision in Rockford Illinois. In the background is the giant Behr scrap metal facility. The signals face south onto the Illinois Railway which intersects the CN here at the East Rockford interlocking (CN milepost 85.6).
The IR Flag Center-Rockford local backs off of the CN Freeport Subdivision main and into the Behr Iron & Metal spur for its nightly switching duties in Rockford, Illinois. Two train crew ride the rear of an open top hopper carrying the reporting marks BIMX for Behr Iron & Metal. In the lower right foreground is the IR southbound lead. This is CN milepost 85.6 which is the East Rockford interlocking with the IR and a Control Point for CN.
A CN westbound train makes its way through the snow at East Rockford interlocking on the CN North Division, Freeport Subdivision at m.p. 85.6 in Rockford IL.
I thought it was interesting that there's a surveying control point atop Pike's Peak. I'm sure the survey crew had a fun time getting up there!
New PTC system antennas recently installed at control point Buckbee (20th Street) on the CN in Rockford, Illinois.

The Furball (Freeport-Burlington local) works at the West Rockford control point/interlocking at milepost 86.70 on the CN Freeport Subdivision in Rockford, Illinois using GTW 5852 for power. The crew is building a huge train in the CN Rockford West Yard to take back to Freeport. That is the infamous Amerock building in the background and the suspension pedestrian bridge over Kent Creek at Tinker Swiss Cottage in the foreground. By most accounts this is the site where Rockford was originally settled in 1834.
CN 2839 leads 5 other engines and a 440 axle mixed manifest freight westbound on the CN Freeport Subdivision at the East Rockford control point (CN milepost 85.6 west) in Rockford, Illinois just after sunset.
Processed initailly with HDR Efex Pro then put through Silver Efex Pro 2 using push process (N +3.0) preset and a control point on the church spire adjust the brightness to 14%, amplify whites to 80% and amplify blacks to -14% to reduce the prominence of it. I then add a grain effect, Kodak P3200 TMax Pro, decreasing the grains per pixal to 77. I cropped the picture so the tracks in the field ran in from the bottom left corner towards the spire which is set just of centre and a vignette to aid in emphasis of the spire.
Pulling up just short of the diamond so the conductor can work out which switch to throw.
I actually updated my train blog! Though not with this spotting. Yet.
A unit train of empty Midwest Ethanol Transport empties passes under the historic Seminary Street bridge at milepost 85.6 on the CN North Division, Freeport Subdivision. The 2-lane road bridge was refurbished in 2008. It sees a daily traffic volume of over 4,000 vehicles.
Norfolk Southern intermodal train 212 is eastbound on the NS Lehigh Line at Phillipsburg, New Jersey, on April 16, 2015. EMD SD80MAC 7211 leads two General Electrics as the train passes through CP-PHILLIPSBURG, where the NS Washington Secondary ties into the Lehigh Line, on its journey from Atlanta, Georgia, to Croxton, New Jersey.

This 100 foot-long wall of solid black granite is inscribed with the names of the 3,095 Ohioans who gave their lives in the Viet Nam War. The statue is a tribute to Gold Star Mothers.
Breanne Delgado is an elemental alchemist. You can find her by the Metropolitan Museum. Those who frequently pass by will easily notice her. Her eyes are very piercing, despite being hidden behind sunglasses. Her smile is contagious. Her charisma as intese as New York.
She kindly agreed to have a few pictures of her taken.
I hope I'll run into her again and take a few more.
You can follow her on Instagram at www.instagram.com/bybreanne/
Two shots posted of same image - one with control points and warping...which points out of the two shots do you like and not like.
I didn't like the sky in the top right corner so I cropped some of it out and toned it down in the control points version.
I also didn't like the smaller building on the left so squared that up....which lost me the big flower pot thing on left side.
The lighting on the grass was too central so I spread it out and up on the control points shot....I also greyed the clouds on the left with some more control point work.
There are some other control points but do they matter to your eye or not?
Post processed in HDR Efex Pro using Grannys Attic preset, adjusting warmth to +15 and using Control Points to enhance the building and clouds.
CSX 673 and 536 approach the East Rockford control point west bound at mile post 85.60 on the CN Freeport Subdivision in Rockford, Illinois. The consist is mostly a unit train of empty ethanol tank cars with a few pieces of manifest freight mixed in. This is the former site of the IC/CB&Q diamond.
My daughter says no more!
Just made control points for Bl, neutral and Wh in CNX, didn't edited the controlpoints. Border in PS
ow btw press 'L' please, much better on black ;-)

Taken from the east end. Sorry it is a rough stitch, Hugin didn't have a lot to work with for controlpoints in the middle sections.

UP 6586 and 7293. Stationary, before you yell at me. The conductor was working at the switch box while the engineer kept her warm.
CN 5655 and CN 2597 lead 2 buffer cars and a loaded ethanol unit train eastbound at milepost 86.30 on the CN Freeport Subdivision in Rockford, Illinois. They are about to cross Loomis Street and will be on the CN bridge over the Rock River in .30 miles and over the East Rockford control point/interlocking in .90 miles.
