One of the UK's jewels

Wiki tells us that the Lake District National Park includes nearly all of the Lake District, though the town of Kendal and the Lakeland Peninsulas are currently outside the park boundary. 

The area, which was designated a national park on 9 May 1951 (less than a month after the first UK national park designation — the Peak District), is the most visited national park in the United Kingdom with 15.8 million annual visitors and more than 23 million annual day visits, the largest of the thirteen national parks in England and Wales, and the second largest in the UK after the Cairngorms. Its aim is to protect the landscape by restricting unwelcome change by industry or commerce. Most of the land in the park is in private ownership, with about 55% registered as agricultural land. Landowners include:
  • Individual farmers and other private landowners, with more than half of the agricultural land farmed by the owners.
  • The National Trust owns about a quarter of the total area (including some lakes and land of significant landscape value).
  • The Forestry Commission and other investors in forests and woodland.
  • United Utilities owns 8%
  • Lake District National Park Authority (3.9%) is based at offices in Kendal. It runs a visitor centre on Windermere at a former country house called Brockhole, Coniston Boating Centre, and Information Centres. It is reducing its landholding.
In common with all other national parks in England, there is no restriction on entry to, or movement within the park along public routes, but access to cultivated land is usually restricted to public footpaths, bridleways and byways. Much of the uncultivated land has statutory open access rights, which cover around 50% of the park.

The lakes and mountains combine to form impressive scenery. Farmland and settlement add aesthetic value to the natural scenery with an ecology modified by human influence for millennia and including important wildlife habitats. The Lake District failed in a previous attempt to gain World Heritage status as a natural World Heritage Site, because of human activities, such as commercial forestry, which have adversely impacted the park's assessment. However, in 2016 the English Lake District bid for World Heritage Status was submitted to UNESCO in the category of cultural landscape. A decision is expected in 2017.

The image below was taken on the eastern shore of Thirlmere, looking north. The word Thirlmere, appears to have its roots in 'Leathes-Water', which was also 'Thirlmere' or 'Wythburn-water' 1769. Probably 'the lake with/at the narrowing' from OE ├żyrel 'aperture', pierced hole' plus OE mere 'lake'.

Thirlmere was constructed in the 19th century by the Manchester Corporation to provide the burgeoning industrial city of Manchester with water supplies. The 96 mile-long Thirlmere Aqueduct still provides water to the Manchester area.

The image was captured with my Canon 5D3 using a Sigma 12-24mm lens at 12mm. Nine images were taken: three exposure brackets at three different focus points. All the brackets, exposure and focus, were automatically calculated and set in the camera, using Version 4 of my Magic Lantern Lua Auto Landscape Bracketing script (see link on the right).

Another little tweak

For those that value getting the best out of your Canon ML enhanced camera, you may be interested in the latest version of my Auto HFD script: download it from the right.

This version first optimizes the aperture for maximum depth of field, before moving the lens to the HFD position.

The lens must report focus distance and be in AF mode. The camera does not need to be in LV, but can be. Also the lens position can be anywhere and the aperture set to any value.

The script will run by simply pressing the MENU key, followed by the INFO key (but you can change these two keys if you wish).

After the script has run, you need to tweak the exposure or run the auto ETTR via ML or the ML auto bracketing for a fully optimized capture.

As usual, I welcome feedback on the script, which I have tested on my 5D3.

Auto Hyperfocal Distance

Things have been busy for a while and photography has suffered. Nevertheless, I did find time to create a small script that some may find of value.

All it does is provide an automatic way of moving the lens to the hyperfocal focus point.

The usual caveat applies, ie you need a Canon camera running Magic Lantern and the Lua module enabled.

In addition, the lens, which can be non-Canon, needs to report focus distance and be in AF mode. The camera also needs to be in Live View, and you should set the Depth of Field option in ML, ie put this in diffraction aware mode for best results.

The script can be downloaded from the link on the right.

To use, simply use the modified key sequence of your choice, in the script you download I use MENU and INFO keys, which work well on my 5D3.

The use the MENU key as normal, simply press the MENU key twice. 

The use the MENU key in the modified state, ie moving the lens to the HFD point, simply press MENU, followed by INFO.

As usual, I welcome any feedback.
