Hello! Dorset-based amateur, published photographer. I mainly take pictures of noisy mechanical stuff, so that’s mainly what you’ll get here, plus any random, cool bits I happen to see. All pictures are taken by me and are my © unless otherwise indicated.

Beautiful!

On Mars, dust grains are ~ the same size as visible light wavelengths, so they scatter red light away (Mie scattering) and let blue through near the Sun.

On Earth, air molecules are far smaller, scatter blue away (Rayleigh) and leave red.

Same physics, inverted colors!

My artwork of a Sunset on Mars. Dust and small particles suspended in the Martian atmosphere scatter light in the direction of the Sun forward. This creates a blue halo around the setting Sun, rendering a Martian landscape quite different from its terrestrial equivalent.

Big skies and blue, blue sea - the view from Cherry Tree Hill, #Barbados. Wonderful, fabulous country. Can’t wait to go back 🥰

If you ever wondered why decent camera lenses are heavy and expensive, here’s why. Look at all that glass! 😍

I love this shot I got of a German #A400M a few months ago. Great aircraft: agile, flexible and with a great soundtrack!

Guillermo del Toro on wealth: "a wealthy man is a man who has enough, not a man that needs more. If you have enough to invite someone for a beer? You're rich. If you have a yacht, planes, islands, and you still need more? You're not rich."

#Ukraine plans to buy 150 Saab #Gripen-E AI-augmented fighters. Cutting edge European tech will make a formidable air force for Ukraine, already training and ready as early as next year. 👊🏼

Forty years ago, James Bond stopped Max Zorin destroying Silicon Valley in "A View To A Kill". In hindsight, we should probably have heard him out.

Griffon and Merlin Spitfires. After weeks of beautiful weather, white skies at #RIAT25 were hugely disappointing. Flat light is good for detail studies though.
