Seneca Improved View 5x7, Osaka 120mm f/6.3, New Guy Collodion (3 months old), 5x7 glass negative
I think my problems are coming down to developer. I can seem to make clean plates just fine and get an image. I think I'm just not developing properly. I got a developer recipe from someone who recently did it successfully (on their first try!). Will try again eventually.
Now... to wipe these plates and try again.
The McLaren Edition SLR is an improved SLR. The upgrade can still be had by any SLR owner who demands more power and better handling!

Max has improved a little more today. He is a little stronger and he went for a little walk this morning with one of the vet techs. She let him walk around and she held his IV bag for him. He also seems to be a little less depressed over all, according to the vet techs. It sounds like he gets a lot of attention from everyone at the clinic. He will be remaining at the clinic for the weekend. They will be testing his blood tomorrow to see if it is improving. I won't be able to visit him tomorrow because they close at noon and I work until mid afternoon. I don't know if they will phone me with the results of his blood work tomorrow or not. I won't be able to see him until Monday, at which time we should have a good idea of whether he has a good chance to make it or not. We are all pretty optimistic about his chances for recovery.
A very big THANK YOU to www.flickr.com/photos/mddog/
for vastly improving my picture. And if you want to see some really great pics you must visit his stream.
I'm not a farmer but I'd love to know why the corn on this farm, and that on many others farms, was never harvested, i.e. cut down. Is this a way to improve the soil? Is there "a best time" to cut it down and that time passed? Calling all farmers for an answer, please...
There are a few scenes in WDW that are fun to take over and over again to see if you can improve on your previous results. This is one of them for me.
Since your Doom Buggy rotates and the Hitchhiking Ghosts come in to view for only a quick few seconds, there is little time react. I've tried various settings, lenses, and cameras, and I think this is my sharpest and cleanest attempt yet. The little D750 does a great job of focusing in low light and has amazing high ISO performance. It also has another trick up it's sleeve...
I stumbled on this somewhat by accident for this particular shot. We had an e-stop in front of Constance Hatchaway (I'll post that shot later this week), and I turned off Auto ISO in attempt to get a cleaner shot. I guess I forgot to turn it back on, so I accidentally shot this one very underexposed in manual mode.
Many reviews of the D750 demonstrate how well you can increase exposure with RAW files from this sensor, and this is yet another example. I pushed this one a full three stops in post to an equivalent of ISO 12,800. In the end it worked quite well.
Maybe someday I'll get a long exposure tripod shot of this scene, but until then I'll keep experimenting!

So one of my goals for 2018 is to improve capturing swallows inflight. Here is a shot of our native Grey Rumped Tree Swift Swallow. This shot was noise and not as sharp as I would like. So still lots of learning and challenges ahead.
Thank you my friends for popping by.
I really appreciate your visits, comments & favourites.

Just a bit of an update. I had planned to be back earlier, but I managed to hurt my back over the weekend and have been trying to get everything back in sync. I’ve had my old back brace on for the past two days trying to get my spine back into alignment and it appears to have been successful. I am feeling much better and having no pain at the moment. I took the brace off this afternoon and went for a slow walk, and everything seems to be back in alignment. Only time will tell. I’m not going to spend much time in front of the computer this evening, but I did want to let everyone know what is going on. Best wishes to everyone for a great finish to this week. Enjoy it to the fullest and enjoy the journey.
Had a great time at the birthday celebration and got to spend some time with my family over the weekend as well before I hurt my back. Comments are turned off as this is just to let every that I am doing fine and should be back in a couple of days. Cheers.

Concerned that this was my first plate after heavy silver bath maintenance. Sure no pinholes but despite a ton of filtering there are small specs all over if you look close on the scan.
Also concerned about the solvent streaks. I bet it was just too cold for any of the alcohol in the bath to actually evaporate. I even added less alcohol and acid to my developer than usual.
Hadrian's Wall is a stone and turf fortification built by the Roman Empire across the width of Great Britain. It was the second of three such fortifications built across Great Britain, the first being Gask Ridge and the last the Antonine Wall. All three were built to prevent military raids by the Pictish tribes (ancient inhabitants of Scotland) to the north, to improve economic stability and provide peaceful conditions in the Roman province of Britannia to the south, and to physically mark the frontier of the Empire. Hadrian's Wall is the best known of the three because it remains the most physically preserved and evident today.
The wall was the northern border of the Empire in Britain for much of the Roman Empire's rule, and also the most heavily fortified border in the Empire. In addition to its use as a military fortification, it is thought that the gates through the wall would also have served as customs posts to allow trade taxation.
A significant portion of the wall still exists, particularly the mid-section, and for much of its length the wall can be followed on foot. It is the most popular tourist attraction in Northern England, where it is often known simply as the Roman Wall. It was made a UNESCO World Heritage Site in 1987. English Heritage, a government organization in charge of managing the historic environment of England, describes it as "the most important monument built by the Romans in Britain".[1]
Sections of Hadrian's Wall remain near Greenhead and along the route, though other large sections have been dismantled over the years to use the stones for various nearby construction projects.

The Roman name of the Wall
No stone inscription survives to confirm what the Wall was called in antiquity, and no historical source gives it a name. However, the discovery of a small enamelled bronze Roman cup in Staffordshire in 2003 has provided a clue. The cup is inscribed with a series of names of Roman forts (see also the botrom of this page) along the western sector of the Wall, together with a personal name and a phrase:
MAIS COGGABATA VXELODVNVM CAMBOGLANNA RIGORE VALI AELI DRACONIS
Here we have Bowness (MAIS, followed by what must be the correct name for Drumburgh-by-Sands (COGGABATA) until now known only as CONGAVATA from the late Roman document, the Notitia Dignitatum. Next comes Stanwix (VXELODVNVM), then Castlesteads (CAMBOGLANNA), before we get to the most tantalizing part.
RIGORE seems to be the ablative form of the Latin word rigor. This can mean several things, but one of its less well-known meanings is ‘straight line’, ‘course’ or ‘direction’. This was used by Roman surveyors and appears on a number of inscriptions to indicate a line between places. So the meaning could be ‘from the course’, or better in English 'according to the course'.
The Staffordshire Moorlands cup, which provides the ancient name of Hadrian's Wall.

There is no such word as vali, but in antiquity Hadrian’s Wall was known as the Vallum, the Latin word for a frontier which is today incorrectly applied to the ditch and mounds dug by the Roman army just south of the Wall. The genitive form of Vallum is Valli, so one of the most likely meanings is VAL[L]I, ‘of the frontier’. Omitting one of a pair of double consonants is common on Roman inscriptions, and transcribing an inscription from a written note is the easiest way to miss out letters. Another similar bronze vessel, known as the Rudge Cup (found in Wiltshire in the 18th century) has VN missing from the name VXELODVNVM, for example, although the letters appear on the Staffordshire cup. The Rudge Cup only bears fort names.
The name AELI is also in the genitive. This was Hadrian's nomen, his main family name and we know that the Roman bridge at Newcastle-upon-Tyne was called Pons Aelius.
Finally we have the name DRACONIS, which can be translated as ‘[by the hand – or property] of Aelius Draco’. It was normal for Roman manufacturers to give their names in the genitive (‘of’), and ‘by the hand’ would be understood. The form is common, for example, on samian pottery.
The translation, therefore, could be:
‘Mais, Coggabata, Uxelodunum, Camboglanna, according to the line of the Aelian frontier. [By the hand or The property] of Draco’.
This would mean the Romans knew Hadrian's Wall as Vallum Aeli, 'the Aelian frontier'.
Dimensions
Hadrian's Wall was 80 Roman miles (73.5 English miles or 117 kilometres) long, its width and height dependent on the construction materials which were available nearby: east of River Irthing the wall was made from squared stone and measured 3 m (9.7 ft) wide and 5 to 6 metres (16–20 ft) tall; west of the river the wall was made from turf and measured 6 metres (20 ft) wide and 3.5 metres (11.5 ft) high. This does not include the wall's ditches, berms, and forts. The central section measured 8 Roman feet wide (7.8 ft or 2.4 m) on a 10 foot base.

Hadrian's Wall extended west Segedunum at Wallsend on the River Tyne to the shore of the Solway Firth. The A69 and B6318 roads follow the course of the wall as it starts in Newcastle upon Tyne to Carlisle, then on round the northern coast of Cumbria. The Wall is entirely in England and south of the border with Scotland by 15 kilometres (9 mi) in the west and 110 kilometres (68 mi) in the east.
Hadrian
Hadrian's Wall was built following a visit by Roman emperor Hadrian (AD 76–138) in AD 122. Hadrian was experiencing military difficulties in Britain, and from the peoples of various conquered lands across the Empire, including Egypt, Judea, Libya, Mauretania, and many of the peoples conquered by his predecessor Trajan, so he was keen to impose order. However the construction of such an impressive wall was probably also a symbol of Roman power, both in occupied Britain and in Rome. Frontiers in the early empire were based more on natural features or fortified zones with a heavy military presence. Military roads or limes often marked the border, with forts and signal towers spread along them and it was not until the reign of Domitian that the first solid frontier was constructed, in Germania Superior, using a simple fence. Hadrian expanded on this idea, redesigning the German border by ordering a continuous timber palisade supported by forts behind it. Although such defences would not have held back any concerted invasion effort, they did physically mark the edge of Roman territory and went some way to providing a degree of control over who crossed the border and where.
Hadrian reduced Roman military presence in the territory of the Brigantes and concentrated on building a more solid linear fortification to the north of them. This was intended to replace the Stanegate road which is generally thought to have served as the limes (the boundary of the Roman Empire) until then.
Construction
Construction probably started in 122 AD and was largely completed within eight years, with soldiers from all three of the occupying Roman legions participating in the work. The route chosen largely paralleled the nearby Stanegate road from Luguvalium (Carlisle) to Coria (Corbridge), which was already defended by a system of forts, including Vindolanda. The Wall in part follows the outcrop of a harder, more resistant igneous dolerite rock escarpment, known as the Great Whin Sill.
The initial plan called for a ditch and wall with 80 small, gated milecastle fortlets every Roman mile holding a few dozen troops each, and pairs of evenly spaced intermediate turrets used for observation and signalling. The wall was initially designed to a width of 3 metres (10 ft) (the so-called "Broad Wall"). The height is estimated to have been around 5 or 6 metres (16–20 ft). Local limestone was used in the construction, except for the section to the west of Irthing where turf was used instead as there were no useful outcrops nearby. The turf wall was 6 metres wide (20 ft) and around 3.5 metres (11.5 ft) high. Milecastles in this area were also built from timber and earth rather than stone but turrets were always stone. The Broad Wall was initially built with a clay-bonded rubble core and mortared dressed rubble facing stones, but this seems to have made it vulnerable to collapse and repair with a mortared core was sometimes necessary.

The milecastles were of three different designs, depending on which Roman legion built them — the Second, Sixth, and Twentieth Legions, whose inscriptions tell us were all involved in the construction. Similarly there are three different turret designs along the route. All were about 493 metres (539 yd) apart and measured 4.27 metres square (46.0 sq ft) internally.
Construction was divided into lengths of about 5 miles (8 km). One group of each legion would create the foundations and build the milecastles and turrets and then other cohorts would follow, building the wall itself.
Early in its construction, just after reaching the North Tyne (construction worked from east to west), the width of the wall was narrowed to 2.5 metres (8.2 ft) or even less (sometimes 1.8m) (the "Narrow Wall"). However, Broad Wall foundations had already been laid as far as the river Irthing, where the Turf Wall began, and many turrets and milecastles were optimistically provided with stub 'wing walls' in preparation for joining to the Broad Wall; a handy reference for archaeologists trying to piece together the construction chronology.
Within a few years it was decided to add a total of 14 to 17 (sources disagree) full-sized forts along the length of the wall, including Vercovicium (Housesteads) and Banna (Birdoswald), each holding between 500 and 1,000 auxiliary troops (no legions were posted to the wall). The eastern end of the wall was extended further east from Pons Aelius (Newcastle) to Segedunum (Wallsend) on the Tyne estuary. Some of the larger forts along the wall, such as Cilurnum (Chesters) and Vercovicium (Housesteads), were built on top of the footings of milecastles or turrets, showing the change of plan. An inscription mentioning early governor Aulus Platorius Nepos indicates that the change of plans took place early on. Also some time still during Hadrian's reign (i.e., before AD 138) the wall west of the Irthing was rebuilt in sandstone to basically the same dimensions as the limestone section to the east.

After the forts had been added (or possibly at the same time), the so-called Vallum was built on the southern side. It consisted of a large, flat-bottomed ditch 6 metres (20 ft) wide at the top and 3 metres (10 ft) deep bounded by a berm on each side 10 metres (33 ft) wide. Beyond the berms were earth banks 6 metres (20 ft) wide and 2 metres (6.5 ft) high. Causeways crossed the ditch at regular intervals. Initially the berm appears to have been the main route for transportation along the wall. The Vallum probably delineated a military zone rather than intending to be a major fortification, though the British tribes to the south were also sometimes a military problem.
The Wall was thus part of a defensive system which, from north to south included:
* a glacis and a deep ditch
* a berm with rows of pits holding entanglements
* the curtain wall itself
* a later military road (the "Military Way")
* a north mound, a ditch and a south mound to prevent or slow down any raids from a rebelling southern tribe.

* Coria (Corbridge)
* Vindolanda (Little Chesters)[2]
* Vindomora (Ebchester)[2]
Garrison
The wall was garrisoned by auxiliary (i.e., non-legionary) units of the army (non-citizens). Their numbers fluctuated throughout the occupation, but may have been around 9,000 strong in general, including infantry and cavalry. The new forts could hold garrisons of 500 men while cavalry units of 1,000 troops were stationed at either end. The total number of soldiers manning the early wall was probably greater than 10,000.
They suffered serious attacks in 180, and especially between 196 and 197 when the garrison had been seriously weakened, following which major reconstruction had to be carried out under Septimius Severus. The region near the wall remained peaceful for most of the rest of the 3rd century. It is thought that many in the garrison may have married and integrated into the local community.

After Hadrian
In the years after Hadrian's death in 138, the new emperor, Antoninus Pius essentially abandoned the wall, though leaving it occupied in a support role, and began building a new wall in Scotland proper, about 160 kilometres (100 mi) north, the Antonine Wall. This turf wall ran 40 Roman miles (about 37.8 mi or 61 km) and had significantly more forts than Hadrian's Wall. Antonine was unable to conquer the northern tribes and so when Marcus Aurelius became emperor, he abandoned the Antonine Wall and occupied Hadrian's Wall once again in 164. It remained occupied by Roman troops until their withdrawal from Britain.
In the late 4th century, barbarian invasions, economic decline, and military coups loosened the Empire's hold on Britain. By 410, the Roman administration and its legions were gone, and Britain was left to look to its own defences and government. The garrisons, by now probably made up mostly of local Britons who had nowhere else to go, probably lingered on in some form for generations. Archaeology is beginning to reveal that some parts of the Wall remained occupied well into the 5th century. Enough also survived in the 8th century for spolia from it to find its way into the construction of Jarrow Priory, and for Bede to see and describe the Wall thus in Historia Ecclesiastica 1.5, although he misidentified it as being built by Septimius Severus:
“ after many great and dangerous battles, he thought fit to divide that part of the island, which he had recovered from the other unconquered nations, not with a wall, as some imagine, but with a rampart. For a wall is made of stones, but a rampart, with which camps are fortified to repel the assaults of enemies, is made of sods, cut out of the earth, and raised above the ground all round like a wall, having in front of it the ditch whence the sods were taken, and strong stakes of wood fixed upon its top. ”
But in time the wall was abandoned and fell into ruin. Over the centuries and even into the 20th century a large proportion of the stone was reused in other local buildings.

Sycamore Gap (the "Robin Hood Tree")
* Hadrian's Wall was featured extensively in the movie King Arthur (which depicted the story of the people the Arthurian legends were supposedly based on). The one kilometre (0.6 mi) long replica, located in County Kildare, Ireland, was the largest movie set ever built in that country, and took a crew of 300 construction workers four and a half months to build. The fort in the movie where Arthur and his Sarmatian "knights" were garrisoned was based on the Roman fort named Vindolanda, which was built around AD 80 just south of Hadrian's Wall in what is now called Chesterholm, in Northern England. In the movie, the fort is attached to the wall.
* Sycamore Gap, a section of the wall between two crests just west of milecastle 38, is locally known as the "Robin Hood Tree". This location was used in the 1991 film Robin Hood: Prince of Thieves, as the setting for an interlude during Robin's journey from the White Cliffs (actually shot at the Seven Sisters Hills) to Nottingham via Aysgarth Falls.
Last week I took an old camera from the 70s, loaded it with a roll of HP5 and went downtown to see what I can do with a vintage camera (and also to test if it is still working). I am quite happy with some of the first pictures. I think I will continue this way to improve. It was lots of fun go back to the basics and use that little camera (Canonet QL17 GRIII).
An improving image, both in vehicle representation and service quality/reliability, can be clearly shown in this photo by Redditch's only double decker. There were a few days where it wasn't on the service last week, but this was due to overhanging trees between Alcester and Evesham (Redditch to Alcester is fine because Stagecoach run double deckers on their route).
Diamond's BJ14 KTC (40625) is seen parked opposite the Alcester Police Station while operating the 247 towards Evesham. The 247 operates up to every hour between Redditch and Evesham Bus Stations. Around the school times, the frequency drops, with certain journeys calling in at local schools, which is why the Gemini was acquired by Redditch because of the termination of the 301 (Redditch-Alcester Schools). BJ14KTC was new in April 2014 as one of two Geminis for use with the Rotala PLC's Wessex operation. Soon after, it gained branding for use on the 51, a service Wessex stepped in to save that First West of England had axed. Sister BJ14KTA was also branded for the service. KTA (40626) has remained at Hounslow in a white livery for the Royal Holloway University, whereas in July 2019, KTC was transferred up to Diamond Bus North West (DBNW/DNW), for use at their newly taken over (from First Manchester) Bolton depot. However, September has seen it transfer down to Diamond Bus West Midlands for use at Redditch on the 247 (Redditch-Evesham) to provide extra capacity on the service following the withdrawing of the 301 (Alcester Schools-Redditch), which ran infront of the service. 40625 is a Volvo B9TL/Wright Eclipse Gemini 2.

My silver bath needs an overhaul. I know I've always been against it but it might be time for a boil.
A pivotal milestone in railship development, the Storm was among the first series of double-gauge rail vessels designed specifically to form a train.
Previous double-gauge vessels were less structurally complex and operated individually. Since these retronymically-termed “rigid” shoulder-less railships were more constrained in their length, (and therefore their volume) by track geometry, the capacity taken up by their internal engines and fuel storage was particularly burdensome.
The improved efficiency of dedicated locomotives within a double-gauge train permitted any non-motive vessel to allocate more of its capacity to weaponry, often resulting in an immense turret spanning nearly its entire beam. The addition of swiveling shoulders between the trucks and body allowed these vessels to grow to sizes far beyond those of rigids.
The first non-rigid double-gauge vessels saw action in the latter stage of the Great Steam War, but remained effective long into the era of internal combustion.

My second trip to VIR. Wanted to improve on some shots from last year and find new angles. Happy to say that I had only 1 fence in my way.
This was also the first time really focusing on using the 400mm for an event since retiring the 100-400. Really didn't miss it or the convenience of a zoom. I am pretty happy with how this 25 year old lens performs.

New and "hopefully" improved version. This will be my third attempt at uploading this video. All I can say is, it plays fine on my computer. It should play well for you'all. Btw- My wife was the videographer. I think she did a fine job.
Sorry - everyone's comments and Favs got deleted when I posted this one and deleted my previous post. If you feel like posting again, that would be appreciated. Thanks, my friends.
PS: That "Wow" girl in the video is my wife - the videographer.

How did I do it? Probabily the wrong way!
Duplicated the original layer, took the new layer and made it almost B&W using saturation slider. Took a 'Polaroid' image from the web and created 3 layers at the top with the polaroid images. Then used the eraser tool to erase the B&W layer under the polaroids to reveal the original bottom layer.

In 2015 I got my degree in Computer Science, and worked on this project for my thesis.
Oripa is a small CAD software developed by Jun Mitani, especially for origami. It implements the most common origami constructions for drawing crease patterns (CPs), and provides some amazing features for flat folding: it checks the Kawasaki-Maekawa-Justin conditions at the internal vertices, and computes previews of the expected folded result! (More details in the attached text and on the original Mitani's Oripa website: mitani.cs.tsukuba.ac.jp/oripa/ )
At some point, the source code was released, and other people began working on it on github ( github.com/oripa/oripa ), adding new functionalities to the project.
I've been using this software quite a lot, as an help in designing new origami, especially tessellations in 2012-2013. At that time I was also an avid student of the mathematics of origami, and felt this software could be improved a lot by adding a few more functionalities.
That's why I began working on it for my degree thesis, to finally work on the missing features I was looking for...
Unfortunately, I could not work directly on github as I had to work completely offline, and could not properly set it up on my laptop. Feel free to integrate my version there too, if you like!
My initial plan was to add the missing origami constructions as new drawing tools to the software. They are more complex than the existing ones, as they must allow the user to choose between up to 2-3 possible solutions. Therefore I started with a new drawing tool, to complete existing vertices where exactly one crease is missing. I did not implement the choice among the possible solutions for lack of time for graduating, and this tool still contains bugs.
In the meantime, I corrected a few bugs, and added some simpler tools, which I felt much more useful for my needs:
- a triangular grid (for tessellators!), as an alternative to the standard square one
- a command to scale up (or down) the CP, when new vertices get too close and could not be managed by the software (it has bugs, I ususally use this command and then switch to an older version to continue drawing..)
- the upper bound for grids is also increased
After graduating in 2015, I did not continue developing this project, as my interest for computer science was diminishing since 2014, while realizing that I was feeling much better when working on different fields and activities, far from computer screens, but that's another story...
Therefore, the bugs I introduced were never fixed so far.
More recently, mxfung had been working on a new version of Oripa for Android ( play.google.com/store/apps/details?id=com.origamitoolbox.... ), and I invite you to check it out, if you have a touch screen device you can use it with!
During these years, I felt that some people could still be interested in this modified desktop version, and maybe in the involved mathematics as well. So here is a link to download Oripa+ (as .jar or zipped), and the texts and slides I prepared for my thesis discussion.
Enjoy!

The first Meteosat Third Generation Imager (MTG-I1) satellite has been at Europe’s Spaceport in French Guiana since the middle of October being readied for liftoff.
With liftoff set for 13 December, the satellite has been placed within the Ariane 5 rocket’s fairing, which protects the satellite during the first part of the launch. The fairing also houses two ‘co-passenger’ satellites: Intelsat Galaxy 35 and 36.
The fairing, which protects the payload satellites during the first stages of the launch, will be jettisoned a little over three minutes after liftoff when the rocket is about 110 km above the surface of Earth when the effects of the atmosphere are negligible.
MTGI-1 carries two completely new instrument that will deliver high-quality data to improve weather forecasts: a Flexible Combined Imager and Europe’s first Lightning Imager.
The Flexible Combined Imager has more spectral channels and is capable of imaging in higher resolution compared to current Meteosat Second Generation’s Spinning Enhanced Visible and Infrared instrument.
The Lightning Imager offers a completely new capability for European meteorological satellites. It will continuously monitor more than 80% of the Earth disc for lightning discharges, taking place either between clouds or between clouds and the ground.

I Would Keep It Clean
A year ago, Eric Raeber started a project where he asked children this question: ”If Earth was the size of a beach ball, what could you do to save our planet?” The children came up with incredibly creative ideas on how to improve the health of our planet, and together with Eric, they illustrated their visions with wonderful images.
Eric has challenged friends at G+ and FB to show us in a photo or a video how they would save our planet if it was the size of a beach ball (or any ball). Alternatively, they had the option of making a difference by planting a few trees at bit.ly/2kIf9V0 and help reach the goal of 100,000 trees by Earth Day. Stacy was one of the persons that got the challenge (you can see her image here: www.facebook.com/photo.php?fbid=10210996065631395&set... ), and Stacy in turn has challenged me.
This is my entry thanks to the challenge from Stacy.
So now, I want to challenge JR McCurdie to show us in a photo or a video how he would save our planet if it was the size of a beach ball (or any ball).
Anyone can make a difference by planting trees at bit.ly/2kIf9V0 and help us reach the goal of 100'000 trees by Earth Day.

This Male Scarlet Tanager knows that he is good looking; and thus he always hides behind leaves and branches in the dense forest. I was very lucky to have captured this image of him in focus....after all these years. I must add, this is the best I have. (smile)
