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.

Learning how to shoot interview videos, and use a green screen to make cool effects in Adobe Premiere
This was a corridor at the Sea Cliff Hotel in Dar es Salaam, Tanzania, which I stayed at before I went out into the wild for 5 months.

Did a horrible job basically, just finished assembling the HiViz.com . Need to work on the background/lighting a bit. I had the Sound Trigger connected to the Delay and then to my Sunpack 344D on full power (don't know how to make it lower, need to investigate that). The flash was about 1.5 feet to camera left, I should have used something for fill on the right.
I only had three burnt out bulbs so I only got to try it three times and the first time I forgot to open the shutter on the camera like a dummy.
Here Robert holds the pizza box while Dawn does the welding and Ernie looks on approvingly. The trick to tube welding in these conditions is to divide the job into quadrants. Here Dawn is contorted to do a quarter-circle of weld in one go.
the Potato Technique is used when oils (linseed oil) rise to the surface of the painting and create a film which resists paint. you can see in this show where the paint beaded up.
i then cut a raw potato and rubbed it on the painting, washed it off with water and painted the rest of the brown lines.
if you look for "Scott Holloway" on youtube you will find some videos of this.

For my project, I used the theme of sleeping and death. Death is sometimes poetically referred to as death. As Hamlet quotes in his famous soliloquy, "To die, to sleep, perchance to dream." I connected the idea of death and sleep to burial mounds, which were large mounds of earth often times marking the grave site of rulers. While I did place my materials with me on my bed, for the idea of sleeping with my project, I wanted to convey that, in order for my project to be created in the first place, I would have needed to die ("sleep"). To emphasize the sleep portion of my project, I used my own down blanket and hand stitched small pillows to place into a mound. I chose brown and green fabric to suggest the earthy colors of a burial mound. The pillows were also stuffed with feathers.
A technique using by fisherman near to beach. They catch small fishes like mackerel, crab, squids, sting rays, prawn using this technique.
A card for my NZ swap group using a Layered Circle technique. I used non-traditional colours to make this Christmas card.
Either this Panda didn't care who watched or wanted us to see the exact technique for eating bamboo.
For the edits on this photos I used the spot healing bush tool to remove blemishes. I also used the teeth whitening technique. I did this by adding an HSL layer and lowering the saturation of the yellows in the image. Because this technique took out much of the color in his face I used the contrast boosting technique. I used a selection mask on his teeth to let the whiteness show through. Finally I used a soft vignette with a gradient mask to sharpen the features on his face.
