Progress on new river Wear bridge, Sunderland

I missed the raising of the supporting pylon, combination of a bad cold and a horrible day!

However these two shots were taken shortly afterwards.  Look out for the heron in the foreground of the vertical format shot.

Christmas Day, Alnmouth beach, Northumberland

We went for a walk around Alnmouth, it was very warm for the time of year, with occasional full sun, but a very strong south westerly wind blowing sand on the beach and spume from the waves.

Hadrian's Wall

The section of the wall just to the west of Housesteads is one of the most dramatic. I probably used my old Olympus 50mm f1.8 Zuiko lens for this shot, which takes in Hotbank Crags, looking east.

Perspective Correction Part 2

In an earlier epistle I listed a number of methods for shooting tall buildings and reducing or eliminating converging verticals. I listed the technique of stacking several images but noted that I had not tried this method.

Well I have now given it a go and have been reasonably impressed with the outcome, see for yourself below.

This is the Emerson Chambers building in Newcastle upon Tyne, situated at the head of Grey Street and currently occupied by Waterstones bookshop. 

I used a Sony NEX 6 camera fitted with the standard Sony 16-50 zoom lens at about 28mm focal length ( 42 mm equivalent full frame). The combined photo used 5 shots, starting at the base working upwards with a healthy overlap between them. 

The images were developed in Lightroom, with the only adjustment being a standard lens profile correction.

The developed images were transferred to Photoshop (CS4) as 16 bit TIFF files, and two different methods of combining them were tried.

1) The easiest way to do this is to use the File Automate Photomerge command, selecting all of the currently open images. This did a job. The main building was not too bad but there was some weird colouration in the sky while the buildings to the rear right were well distorted.

2) The next method is a tad more complex, but produced a better result.

I selected and copied all of the images over to the base layer (the bottom of the building) so as to obtain a layer stack of images. I then selected all of the layers and used the Layer Align command, followed by the Merge Layer command.

The resulting image was a great improvement on that produced by method 1, but there was still some distortion of the buildings to the rear right, and  a little chromatic aberration along a couple of edges. 

Some Photoshop skulduggery was able to sort all that out to produce a final photo that is 6616 x 4628 pixels in size. Printing at 300 dots per inch would result in  finished dimensions of about 22 x 15.5 ", but the quality of the original and, taking into account a sensible viewing distance, would allow a much larger reproduction were it required.

Edit - I've played around with this technique rather more now and have found that the degree of perspective correction appears to be related to the geometry of the base level shot. If your camera is completely level as you take the first shot, the software tries to mimic that geometry as it adds the layers above. While this may sound a good thing, an image without any trace of convergence of the verticals looks a tad strange, while the top layer has to be contorted rather more than might be considered comfortable in order to comply. I guess that I'm still in the experimental stage, but I am beginning to prefer a base level shot that is just off the horizontal, so that the resulting image has some degree of natural perspective after assembling all of the layers.

I've also tried the automatic panorama feature in Lightroom 6 (Right click, Photomerge), which is surely the quickest software fix for this problem, but I have not been as impressed with the results as with those that I have achieved using my venerable copy of Photoshop.

Warkworth to Amble, Northumberland

We drove north to Amble, under grey skies most of the way. The weather forecast did not lie however, it was cold but bright in this part of Northumberland. Our walk went from Amble to Warkworth and return, along the course of the river Coquet.

I had forgotten the wealth of wildbirds that you see in this part of the world. There were eider duck in the harbour, a heron fishing along the river bank, the cry of a curlew, and oystercatchers above.

Carol spotted a seal catching a fish in the river.

Gasometers - Hendon, Sunderland

Gasometers, or gas storage tanks, are a rapidly disappearing feature of the landscape.  I noticed that they are currently dismantling the tank at Wallsend, long a Tyneside landmark, and decided that I should photograph the Sunderland gasometers before they also go.

There are three surviving tanks on the Hendon site and they represent an evolution of the technology from early to late Victorian, and then 20th century. The oldest tank has ornate cast iron columns, the late Victorian tank has a riveted steel framework, while the most recent is self supporting.

The last time I looked at the tanks a few years ago, they were still in use, but today they look  sadly neglected and I suspect that their days are numbered.

I'd like to see the oldest of the three preserved, if at all possible.

Sunshine at Roker

Before the rains came this week, we had some fabulous summer sunshine.

It's not often that it's warm enough to swim in the north sea at Sunderland, but this photo of Roker/Seaburn beach shows people choosing to sit in the shade, to get out of the sun!

Cragside, Rothbury, Northumberland

We try to get to the National Trust property Cragside at least once every year, and the best time to go is normally early June, when the azaleas and rhododendrons are at their best. This year we have had a severe winter and a cold wet spring, so things are a tad out of joint. There were some fabulous flowers to be seen, but nothing like the profusion of bloom of previous years at this time. However there's always something of interest to see at Cragside, our all time favourite NT location.
