Cold refers to the condition or perception of having low temperature; it is the absence of heat or warmth. Many things are associated with cold, such as ice and the color blue. Fluids used to cool objects are commonly called coolants.
n fisica, la temperatura è la proprietà che caratterizza lo stato termico di due sistemi in relazione alla direzione del flusso di calore che si instaurerebbe fra di essi.
Perception~
Perception can be a tricky thing. With a visit to Snoqualmie Falls, my girlfriend became the subject of the photo, however, I feel the power of the picture is represented int he size of the cascading water in respect to the observer.

Actually calm, not windy. Dance with your partner, here?
依頼されていた林が、やっとできました。現地の風は穏やか。二人で踊れる場所です。
Townhouse design intended to play on the cinematic camera shot commonly known as the 'Hitler Cam' or the 'Andre Cam'.
Recent brief on perception of place, influenced by the notion of everchanging perception due to many factors and the environment we are in, etc. 35mm black and white film.
I have always been told I am an old soul. In this portrait, I chose to give myself a third eye because I wanted to show that I have a lot of direct energy inside of me. The third eye is blind, but it also is a mirror inside of yourself. I made this drawing when I was learning a lot about myself and how I perceive the world.
We bring to photography many expectations and assumptions of what the image 'should' be like. I want to play with these assumptions. Here there appears to be information missing but can we use our imaginations to fill in the gaps? How much information can be taken away before the image is useless? If this seems exaggerated, think of a black and white photo, this is a process of discarding the color information from the image.
What we need to realise is that our perceptions of the world are always filtered anyway and what we think we see and know isn't always true but merely our attempt to make the world the way that makes sense to us.
More often we want to see what is there rather than what is not there. Many of my images in general play with the idea of negative space - or what is not there. Rather that seeing the leaves on the tree, try to see the spaces between.
I am interested in the philosophy of images and our perception of the world. Here, and with some of my recent images, I am attempting to understand more and experiment with image-making.
Photographic techniques capture electromagnetic wavelengths beyond human vision, revealing features invisible to the naked eye. These signals are processed into interpretable forms using methods like color mapping.
Pink lacks a specific electromagnetic wavelength, while grey poses a limitation due to its representation of only intensity—a blend of light and dark without spectral specificity. Imaging techniques reliant on spectral variation produce identical results for greyscale images unless non-visible data is present. Deviations from this uniformity may indicate errors, misinterpretations, or unknown phenomena.
Contention persists over analytical debates, including dismissible claims like Van Allen belt dangers and contested evidence of lunar mirrors. The precision of laser reflections targeting a moving 3x3-foot marker on the Moon highlights technical skill but often fails to resolve skepticism. For instance, a 0.1° shift moves a laser spot 670 km across the Moon's surface.
Forensic analysis (2022, 2023) of Apollo 11–17 photographs assessed authenticity claims. Images of humans in space, Earth, and the Moon's distant views were validated, but Moon landing visuals showed variations, suggesting diverse techniques may have replicated certain elements.
PEMi (Photoelectromagnetic Image) software enhances forensic analysis by differentiating natural and artificial light sources, revealing hidden features. Each PEMi-ID links to original sources, ensuring traceability and comparison.
