3D Steering Wheel

By
As a child, 3D imagery mystified me. I used to marvel how a flat photo had depth. Even today, anaglyphs still instil an element of mystery, even though I know how it works. It's magic right? Lol.

I have a 3D camera to capture my 3D photos, I also have a pretty good app on my phone too. My camera is the now defunct Fuji 3D W3. 

3D Anaglyphs: A Brief Overview

Anaglyphs are a type of stereoscopic 3D image that can be viewed without special equipment. They work by using two different colours to represent the left and right eye views of a scene. When viewed through red-cyan glasses, each eye sees only the image that is meant for it, and the brain combines the two images to create a 3D effect.

Anaglyphs were first invented in the 1850s, and they have been used for a variety of purposes, including movies, television, and video games. They are also popular among amateur photographers and artists.

How Anaglyphs Work

An anaglyph is created by overlaying two images that have been filtered with different colours. The left eye view is filtered with red, and the right eye view is filtered with cyan. When these two images are viewed through red-cyan glasses, each eye sees only the image that is meant for it. The brain then combines the two images to create a 3D effect.

The amount of depth that is perceived in an anaglyph depends on the difference between the two colours that are used. The greater the difference, the greater the depth effect will be.

Benefits of Anaglyphs

There are several benefits to using anaglyphs. First, they are relatively inexpensive to produce. Second, they can be viewed without special equipment. Third, they can be displayed on a variety of devices, including computers, televisions, and smartphones.

Drawbacks of Anaglyphs

There are also some drawbacks to using anaglyphs. First, the 3D effect can be somewhat blurry. Second, the colours in an anaglyph can be distorted. Third, not everyone can see the 3D effect in anaglyphs.

Why Greyscale?
 
It's my preference. Greyscale anaglyphs work better than colour anaglyphs because they are less likely to cause eye strain and headaches. This is because the brain is more easily able to distinguish between two different shades of gray than it is between two different colours. Additionally, colour anaglyphs can sometimes produce a "ghosting" effect, where the image appears to be doubled. This is because the two different colours of light are not perfectly filtered out by the eyeglasses, and so they can both reach the retina at the same time.

Conclusion

Anaglyphs are a simple and inexpensive way to create 3D images. They are a popular choice for amateur photographers and artists, and they can also be used for a variety of other purposes, such as movies, television, and video games.

If you are interested in creating your own anaglyphs, there are a number of software programs that can help you. You can also find a variety of anaglyph images online.

My Running Buddy

A photo a day.  My running buddy.  I run alone. I like the peace and quiet. It allows for deep thought (and sometimes no thought at all). The hormones released are fantastic at clearing the mind of most worries. I often run first thing in the morning, as it sets me up for the day. During the winter months, first thing means it's always dark.  For the last two years I used a cheap Chinese head torch. It was advertised as 5 million lumens, or something silly like that. Don't get me wrong - it was really bright. And warm. But the batteries only lasted half an hour. Two weeks ago, I bought this beauty from Energizer. It cost more (£30) than my previous torch, is nearly as bright, but is much more conservative with the batteries. That's a winner for me. It's very rare for the moths in my wallet to see the light of day. So. If you see someone in the Cleator Moor area around 6am, with head torch and high viz jacket, running like he has shit himself - that will be me 😁  Yes. I

A photo a day.  Joy follows.  A walk with the ubiquitous Poppy. Buddha : We are formed and molded by our thoughts. Those whose minds are shaped by selfless thoughts give joy when they speak or act. Joy follows them like a shadow that never leaves them.

River Ehen

A photo a day.  Wath Bridge. Heavy rain over the past few days has swollen the local rivers. This is a shot at the double arched Wath Bridge, which was built in 1816 to replace the earlier Dent bridge. The fast flowing River Ehen is fed from Ennerdale Lake, with the River Keekle adding to its volume at Cleator. It flows through Egremont and then out to sea near Seascale.  The River Ehen is a designated Special Area of Conservation (SAC) and a Site of Special Scientific Interest (SSSI). The river is home to a variety of wildlife, including salmon, trout, freshwater pearl mussels, and kingfishers. The River Ehen is a beautiful and important river. It is a popular spot for recreation and a vital part of the local ecosystem.

St Bees

St Bees is a beautiful village on the west coast of Cumbria. It is a popular tourist destination due to its stunning scenery, long sandy beach, and proximity to the Lake District National Park. The village is named after St Bega, an Irish nun who is said to have landed here in the 9th century. She founded a priory on the site, which is now a ruined abbey. The village church, St Bees Priory Church, is dedicated to St Bega and dates back to the 12th century. St Bees is also the start of the Wainwright Coast to Coast Walk, a long-distance footpath that runs from St Bees Head in Cumbria to Robin Hood's Bay in Yorkshire. The walk is one of the most popular in England and takes in some of the most beautiful scenery in the country. If you're looking for a place to relax and enjoy the stunning scenery of the Lake District, then St Bees is the perfect place for you. There are plenty of things to do in the village and the surrounding area, including walking, hiking, swimming, fishing, an

Adorable

Lambs are adorable. They are born with soft, fluffy wool that keeps them warm and protected. Lambs are also very playful and curious, and they love to explore their surroundings. Lambs are born after a gestation period of about 5 months. They typically weigh between 6 and 8 pounds at birth, and they are able to stand and walk within a few hours of being born. Lambs will nurse from their mothers for about 6 weeks, and they will then start to eat grass and other plants. Lambs are social animals, and they live in herds. The herd is led by an older ewe, who is responsible for protecting the lambs from predators. Lambs are also very protective of their mothers, and they will often bleat for their mothers if they are separated from them. Lambs are an important part of the agricultural industry. They are raised for their wool, meat, and milk. Lamb meat is a popular food in many cultures, and it is a good source of protein. Lamb's wool is also used to make clothing, blankets, and other tex

A photo a day. The heavens opened. I was travelling along a local road when the rain intensified. I pulled over to a safe place to grab this pic. Sadly, you can't make out the rain in the photo - but I think you will get the idea. Torrential is an understatement.

Demolished

I was quite saddened to see the former Grove Court Hotel at Cleator almost demolished, earlier this morning. Originally built in 1907 as a Roman Catholic Infant School, the school became a hotel in 1987. Following a kitchen fire in 2009, the hotel closed and never reopened.  The school was small, with just two classrooms, and it was designed to accommodate around 100 children. The school continued to operate until 1968, when it was closed due to falling enrollments.

Evicted

A photo a day.  Bird bailiffs.  I totally understand the need for tree management, but does it need to be done in Spring, when birds are beginning to pair up and build their nests? The photo below is from one small stretch of a local bridleway.  Hundreds of branches have been trimmed from local trees, effectively evicting any birds that are beginning the nesting process. Why not cut-back in Autumn?  In a week, or so, the bird-bailiffs will return, to place the trimmed branches into a chipper. I'm annoyed.
