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.

CIFOR-ICRAF has organized a one-day training event that aims to disseminate the science-based technique and lessons learned, and to share with the various stakeholders in blue carbon – that is, policymakers, practitioners, the private sector, academicians and researchers, as well as civil society – all relevant technical knowledge related to blue carbon monitoring and development.

For 7 Days of Shooting, Technique Thursday.
So I decided to go for a game theme here for outside the box. I got one of my dogs to play along for this. She says, "Ok mom. Put the camera down and take your turn already."
What I did here was set up the game obviously, then I lured Daisy onto the chair with a treat. I told her to stay and she actually listened. I played with saturation and some other stuff I don't remember (oops) in Corel and then added the "photo edges" there as well to make it look like an older photo.
2. They didn't have a green that I liked so I picked a bright one and black. Mix main colour with a drop of black (start with less black and add more to make it the shade you want).
For our first project, we fired the enamel with torches, so we could see what happened as it went through the different stages of fusing. After getting two coats of the base layer on, we laid lumps and strings of enamel on top, heated them, and swirled them with a metal probe. I think it takes practice to create attractive designs this way. Mine is hardly lovely, but it was good as a learning piece.
Metal sample collection demonstrating knowledge of different craft techniques Eg. Annealing, enamelling and forming. Made January 2013.
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.
I chose black and red paint to show the pain expression during mother's pregnancy and even giving a birth.
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.
Your crimps should never fail. Your line will fail before the crimp 100% of the time, if you do it the right way. Learn how to do it the right way in this Crimps and Crimping Technique instructional video.
RJ Boyle tests the limits of terminal tackle on a regular basis, chasing giant bluefin, grander marlin and swordfish. In this video, he will explain in great detail the various crimping tools, the differences between crimps and the proper crimping technique required to ensure your success!
