Metal sample collection demonstrating knowledge of different craft techniques Eg. Annealing, enamelling and forming. Made January 2013.
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.

Clearly a first-timer at the beer funnel races, this feet-first technique requires a 180-degree body rotation in order to begin the imbibation portion of the contest.
Compositional Techniques: I used symmetry and leading lines.
Materials: I used a grass path in Golden Gate Park with the surrounding brush and my Nikon D80.
Idea: I was walking and came across this path and remembered that one of the easiest ways to get two compositional techniques in one photo was symmetry and leading lines, which is what I used. Walking in nature reminded me a lot of country music, so I decided that would be my genre for this picture.
Process: To take this picture, I got really close to the ground and angled the camera right in between the path lines. I made sure everything looked the same on both sides and snapped the picture. In editing, I tried to take away most of the noise and made sure to really bring out the green and the sunlight. The low number of materials really brings out the simplistic nature of the country and because of that, country music.
This technique came about whilst I was making the bleach technique cards.
Base: normal white cardstock
background: applied 3 colours of pigment inks randomly all over, heat dried it. Then went over the top with a contrasting pigment ink - just smooshing the ink straight from the inkpad to completely cover the entire card.
Before it dried I inked up my chosen rubber stamp and stamped directly onto the ink covered card. The result is what you see before you.
When you go over the first dried layer of ink with your second colour it doesn't completely obscure the colour underneath and when you stamp your image on, that also slightly lifts off some underlying colour - it's quite subtle but the effect is really good.
I then went on to stamping a few more elements to frame the card and Krylon edged the card before completing with some lace.
Referred to as “modern miracle”, Emotional Freedom Technique (EFT) is a revolutionary psychological acupressure technique that is used to tap into & remove any blocks that disrupt the flow of body’s innate healing & preventative powers. EFT traces the root cause of all negative emotions & dramatically relieves the emotional disturbances & physical symptoms in mere minutes. Its results are long lasting and the entire process is easy enough for self-application.

We tried using some random household objects as color filters. It was fun. I'm not sure what's going on with this glass, but check out the progression in the next few pics.
