Working on the SUBSA experiment. It stands for "Solidification Using a Baffle in Sealed Ampoules" which doesn't help much to understand what is going on admittedly. We were processing samples of metal alloys for researchers to observe how they are cast. Metallurgy is a hot subject for space research (not only because of the casting temperatures #dadjoke) because how metals form is complicated, very precise, and as metals are used everywhere on Earth improving them could have enormous benefits. As metals form, they grow crystals that resemble Christmas trees, and these crystals influence the strength of the metal. On Earth gravity influences how these crystals grow, so observing the process in space helps to understand the process, making it easier for researchers to create mathematical models. ESA has a facility called the Electromagnetic levitator in the Materials Science Laboratory to conduct research in this same domain. After the bronze age and iron age this type of research could lead to another metal age... 😎 An observant viewer will notice that I am wearing different t-shirts – no I didn't spill any (they are in sealed ampoules remember!) but the experiment runs over many days, actually the Materials Science Laboratory was running similar metal batches in Columbus too!
L’expérience SUBSA sur laquelle j’ai déjà travaillé plusieurs fois (les plus observateurs auront remarqué les t-shirts différents 😉) : en gros, c’est de la métallurgie spatiale. Les alliages sont un sujet assez chaud pour la recherche spatiale, et pas seulement à cause de leur température de fusion (je ne résiste pas à la blague de papa 😄). L’amélioration des alliages, omniprésents dans notre vie moderne, a évidemment un potentiel d’applications immense sur terre. Les métaux se forment en poussant comme des cristaux (avec une forme un peu sapin de noël si on a de l’imagination), et ces processus sont fortement influencés par la pesanteur, d’où l’idée d’enlever ce facteur pour mieux les appréhender. Après le bronze et le fer, ces recherches pourraient donner naissance à un nouvel âge du métal 👍

I didn't have a clear layout in my head when I started so I threw so black Lego shapes in abstract arrangements (bottom row; sometimes doing test shots like these hits upon a cool image that I can develop and refine but other times it just doesn't catch). I wasn't feeling those Lego ones so I tried pot plants (middle) then lastly old tree stumps I have outside (top).
One of many men helping us switch out flooring, move into the house, out of the Alaska house. Some expressed their dissatisfaction with my camera with awkward gestures. This chap did not.
But he did not pose. I just kept clicking. Moving is such fun.

Thanks for looking as I experiment. Hid this during a bit of anxiety; thanks again for the encouraging comments.
I've been up all night trying to get some work done, and thought I'd take a break by playing around with some photos in GIMP. Due to lack of sleep, my judgement is a little impaired and I thought I'd try two things I told myself I'd never do.
This is number 2: add text (let alone poetry) to an image. I remembered this poem when I was looking at my contact sheet and just couldn't resist. You can tell I wasn't really committed to the idea because the text is so small, you probably won't be able to read it unless you view it large. Do you think this works, or is it just lame?
btw the poem is:
春雨や傘さして見る絵草紙屋
正岡子規
which translates roughly to:
spring rain,
browsing under an umbrella
at the book stall
My girlfriend gave me a Polaroid Snap camera for my birthday! It's an interesting mix of digital and analog technique. The camera saves a digital version of every shot on a memory card and prints one version on paper. Also, it's not really a "printer camera", since the development of the shot is, like in traditional Polaroid cameras, inside the paper itself. But instead of using chemicals (at least I think there are non involved) the paper uses some kind of crystals that takes on the colors of the shot.
The camera also has some handy features, like the choice of using a classic Polaroid frame or not and the choice of black&white, color and vintage color shots. Also, there is a photo booth feature that takes four shots in a row and prints them on the same paper!
It might not be as elaborate or fully interesting as the classic instant films, but it's surely more convenient and a lot cheaper (about a third of the price per shot). These are some of my favorites from the first 20 papers I've used. I've chosen to scan the paper versions rather than uploading the digital versions, to preserve the colors and feeling from the pictures as I see them. There will probably be more to come.

I finally found out how to do texturework :P Yeah I'm not the brightest... Haha!
But this is only an experiment... I'm just learning and going through streams with people that are super at working with textures! Trying to get inspired.
Just chose a simple subject this time... But sometimes that's good too :P
Sadly the shot was a little dark to begin with, but well... Yeah and I used a little TS!
Just wanted to say thanks to you all for the super comments you always throw my way! Hope you have a terrific Tuesday!

I didn't know what to take pictures of today. But then I remembered we have an old, chunky tv in our basement. So I experimented with that. A little bit poltergeist...

Profession gardien de Zoo à mi-temps, il faut assurer le repas bi-hebdomadaire des tardigrades de l’expérience Cell Science 4 🔬. Les chercheurs étudient les effets de l’impesanteur et de l’environnement spatial sur ces créatures microscopiques qu’on surnomme parfois oursons d'eau. L’espèce la plus grande peut mesurer jusqu’à 1 mm de long, mais en général ils sont microscopiques… Ces créatures sont incroyablement résistantes, capables de survivre à des environnements extrêmes sur Terre comme dans l’espace : certains sont revenus de plusieurs jours à l’extérieur, dans le vide, avec des températures de +100 à -100 degrés, sans un dommage... Dans le cas de Cell Science 4, les scientifiques essayent d’identifier les gènes qui leur permettent de survivre durant des séjours plus ou moins longs dans l’espace, et d’évaluer comment l’utilisation de ces gènes change au cours des générations dans le but d’exploiter pour les humains les secrets de leur incroyable résilience !
Feeding the tardigrades! 🌱 Researchers are investigating the effects of microgravity on these microscopic creatures, also known as water bears, through an experiment called Cell Science 4🔬 #DYK the largest tardigrade species is just over 1mm in length and they're incredibly hardy – surviving extreme environments in space and on Earth. In this case, researchers want to characterise the genes that allow tardigrades to survive during short and long periods in space, then assess how the use of these genes changes across generations Maybe we can harness their secrets!

This was taken from my suburban back garden with some light cloud and street light glow but I was just glad to get out after so much cloudy sky in Ireland.
A view through Orion and Taurus.
A little bit of experimentation - A NISI night sky filter AND a Tiffen double fog 3 attached to the front of my lens - a little vignetting but surprisingly minimal.

i made a little logo for myself the other day using some type i created. i decided to flesh it out into the rest of the alphabet and see what happened.
Anna is crazy about doing experiments. She went out on the patio tonight with a whole bunch of things to conduct some serious experimental work. She loves discovering new things.
Experimenting with a bright flashlight to do light painting this morning using the new Canon 6D, before sunrise, at home, at the Golden Gate, and the Palace of Fine Arts, San Francisco, USA. I'm not impressed, could've taken these easily with a cheaper camera. My guest bedroom in the far end had lights on, I used the flashlight to illuminate the corridor.
This was my first real attempt to create a finished illustration in the "tradigital" mode - an traditional drawing/painting with a digital finishing. I painted with acrylics and watercolors over a graphite drawing on a 300gms Fabriano paper, scanned and then retouched/enchanced some details on Photoshop. This illo is a landmark for me, and it definetly synthesizes a new way of creating images for the future. The result is so more organic, fluid than the digital paintings!
Hope you enjoy the result, too.
