the 300mm f/4 is creepy, seriously. this image ist reduced by 50%... best combo with a d850 ever :o)
IC 434 is an emission nebula visible in the constellation of Orion; thanks to its presence it is possible to observe the famous Horsehead Nebula, a dark cloud that overlaps it on our line of sight.
This is an H II region that extends south of Alnitak, on the southwestern edge of the large Orion B cloud; it has a very elongated shape in a north-south direction and receives the ionizing wind directly from the star σ Orionis, a bright member of the large Orion OB1 association.
The nebula reaches 70' in length and is easily shown in long exposure photos or CCD images, although its thickness is only a few arc minutes.
The temperature of the region was measured using various methodologies and exploiting various radiation ratios, initially obtaining values between 8000 K and 7600 K;
subsequently this value was reduced to 3360 K and even less depending on the map taken as reference.[3] A study on electronic temperature conducted in 1992 instead provided a value more similar to the previous ones, which is around 6000 K.

Anybody notice something odd about The Moon last night?
As my shifts mean I'll be working over Halloween, we had a mini celebration last night, featuring the classic movie Salem's Lot. This photo is outrageously plagiarised, I mean 'inspired', from the last shot of that film. It's a photo of The Moon, alas not quite full but I can only photograph what's up there. That was desaturated. A second macro photo of a death's head signet ring was added as a layer in Photoshop, some red was added and its opacity was reduced to 50% .
Happy Halloween all.
It was pouring the day we visited the P&W back in August, 1978. But the engine facility was full of Alco/MLW products, and we kind of figured we weren't going to melt. And having manual 35mm cameras meant that the odds of water damage were greatly reduced. Here's the rear end of the 2002, kind of a love it or hate it rear end, too.
On the evening of the 28th May 2020 Class 66/0 no.66059 passes Powderham with the 6Z60 1151 Parkandillack to Bescot Down Side.
Clay services from Cornwall have been reduced to just ten wagons per week rather than the normal 20. The train currently runs direct from Cornwall to Bescot before working forward to Cliffe Vale in Stoke-on-Trent where the china clay is generally used in chemicals and paint. The locomotive is one of five modified for banking duties on the Lickey incline in Worcestershire and carrys an additional headlamp to assist with coupling and uncoupling in the dark. Unfortunately there will be no need for a banker up the Lickey with this light load.

Up on the first walk after French lockdown was reduced, I went on a foggy and wet day to Calerne plateau.

I was asked to do a series of my own personal favourites on the blog. I will post one favourite each day this week.
Yesterday when I crested the highest dune I couldn't see the ocean for the thick fog. Once I reached the waterline I saw that the tide had exposed a sandbar not far from the shore. Immediately I remembered that last year I had seen pelicans grounded on the sandbar under the same conditions.
No sooner had I walked I few yards than the same scene appeared in front of me through the fog. Unlike seagulls, pelicans do not like humans approaching them too closely.

This is the view from inside one end of the viaduct to the other. I have long meant to go there to take this view and as we were visiting Borde Hill garden, which is less than a mile away, today I took the opportunity
Information:
"The viaduct is 96 feet (29 m) high and is carried on 37 semi-circular arches, each of 30 feet (9.1 m), surmounted by balustrades, spanning a total length of 1,480 feet (450 m). Each pier contains a Jack arch with a semi-circular soffit to reduce the number of bricks required. At each end of the abutment is an ornamental square open tower, the brickwork of which is faced with stone from Heddon Quarries near Newcastle-upon-Tyne. The viaduct was designed by engineer for the line John Urpeth Rastrick in association with the architect of the London to Brighton railway, David Mocatta. It has been described as "probably the most elegant viaduct in Britain."
Work to build the ornate viaduct began shortly after an Act of Parliament was passed in July 1837 giving the London & Brighton Railway company assent to construct the line to the south coast. More than 11 million bricks were shipped across the English Channel from the Netherlands to Newhaven and Lewes. Caen stone was also brought from Normandy in France. Building materials were transported to the construction site on barges up the Ouse River Navigation.
The Brighton main line was opened in two sections because completion was delayed by the need to construct some major earthworks. The viaduct was officially opened when the section between Norwood Junction - Haywards Heath was opened on 12 July 1841. Initially there was only one track in operation. The second line along with the viaduct's ornate stone parapets and pavilions were not completed until the following year.
By 1846, the viaduct had become part of the London, Brighton and South Coast Railway. In 1923 it became part of the Southern Railway network until nationalisation of the Big Four (British railway companies) in 1948.
Despite the structure's fine design, materials and architectural features, the viaduct has had an expensive and problematic history.
First, in the 1890s major repairs were made to the brickwork because engineers of the late Victorian era were concerned that the original lime mortar used in the viaduct's construction was inadequate. It was decided that this should be replaced with cement mortar. However, replacement facing brickwork and substandard mortar eventually caused its own failures prompting more expensive repairs. Second, as the parapets and pavilions were made from Caen stone, a high-quality limestone, they have been subject to heavy weathering. By 1956, the damage was extensive but the cost of refurbishment work was deemed too much by British Railways, the UK's nationalised rail operator.
Although by May 1983, the viaduct had been made a Grade II* listed building, its eight pavilions were in such a poor condition that some of their roofs had fallen in and internal props were required to stop them collapsing further. English Heritage refused British Rails' request to demolish the buildings. The fabric of the structure continued to deteriorate over the next decade. Stonework had begun to fall away from the balustrades and parapets.
Starting in 1996 - with grants from West Sussex County Council, Railway Heritage Trust and English Heritage - the viaduct underwent a £6.5 million renovation over seen by Railtrack. Harder wearing limestone was imported from Bordeaux to ensure the closest match with the existing Caen stone in the balustrades and pavilions. Some of the piers had to be reconstructed because of failures in the Victorian brickwork. The new bricks were handmade in a variety of sizes to suit the existing brickwork and set in a sand, cement and lime mortar. Throughout the work, one line always remained open while restoration was carried out on the other side of the viaduct. The project, which was took more than three years, was completed in September 1999."

(homeless woman, sf, 11/12/06)
homeless rebecca from detroit. rebecca doesn't fit. as though she's not where she's supposed to be. i see her as i pass. she is almost ghostly. she sways and bends like the only tree on a hill; unprotected. she seems resigned to a losing battle.
she is panhandling as i pass. or she is praying or mourning. but she is not seen. i turn the corner and watch her for a moment. she grimaces her mouth as though swallowing some new resignation and moves away from the season's passing throng; in my direction, but floating by. i seem to snap a trance when i say hello.
she's been homeless since 1998. she sleeps sometimes in shelters. but says there's not enough beds for women. the men have many more. she went to the shelter this afternoon to put her name in for a bed this evening. there's a lottery, and she didn't get one.
says she has no family and no children. she's the only one. but she has one girlfriend who got a place from the city finally after years. says she's trying to stay there with her friend tonight, if she can make up the guest fee. she's about a third of the way. it's been cold and she clearly doesn't want to be on the street tonight.
she was an accountant not so long back. she had a good job. she worked for kgo. but in '98, they were downsizing her group and she was let go. she thought she'd get another job easy. but she never did. they all wanted someone younger. and now she's 54, and says it's too late for her.

Light settings:
On the left front I have an octabox, on the left of the model is a second studio lamp that gives a little more power to give her face profile especially.
A reflector causes the light of the studio lamp to be reflected to the left to soften the shadow.
In this picture, the contrast has reduced the contrast, in addition to the soft color tones in the picture, reduces the contract that the picture becomes a unit.
Mindy's direct look keeps you looking at the photo for a long time.

Still busy, these next two weeks will probably be even worse...
Getting stronger, on Thursday they scheduled me the final job interview (already succesfully passed through two) for a really interesting opportunity.
I will be meeting the General Manager of the company. Sounds good!
