A week or so ago I went to a printing workshop. I took photos of the prints, then used some as layers and blended them.
Taken with a Nikon Pronea-S camera in week 225 of my 52 film cameras in 52 weeks project:

The Nikon Pronea-S is the second APS camera that I have used. The APS (Advanced Photo System) was introduced in 1996, it used 24mm wide film, and had provisions for three different aspect ratios to be selected, though the negative always recorded the full frame, and the different formats were implemented at the printing stage, with data being read from the film to tell the machines which aspect to use.
APS was a short lived format as soon after it was introduced digital cameras started to become more affordable, and the non-technically minded snap shooter, for whom the APS system was ideal, soon switched to digital. The film is no longer made, but is still fairly easy to find online. This Fujicolor Nexia A200 colour negative film was in the camera when I found it in a charity shop, only the first few frames had been used. I adapted one of my 35mm spirals to take the 24mm wide film, and developed it in the Tetenal C41 kit.
Unlike the Minolta APS SLR that I used recently, the Nikon accepts all the Nikon mount lenses, so I was able to use my 18-200mm VR lens which is made for the smaller than full frame DSLRs, there is some vignetting at the wide angle end of the range, but otherwise the lens works perfectly with the APS negative size.

What is 3D Printing Service?
3D printing technology is a collective term for a series of rapid prototyping technologies, the basic principle of which is laminated manufacturing. 3d printing service providers will use a computer-aided design model to produce a three-dimensional object. 3D printing service includes 3d design and printing services, 3d laser printing services, 3d model printing services, 3d plastic printing services, 3d prototyping service or 3d rapid prototyping services, etc. SLA printing service and SLS printing service are two common types of 3d model printing services.
3D Printing Processes
SLA（StereoLithography）
SLA means laser curing rapid prototyping technology, the process of molding is to dip the photosensitive resin liquid through the workbench, and then irradiate the liquid surface by ultraviolet light, and the irradiated part is immediately solidified and formed. After the layer is formed, the workbench is lowered. The height of the layer, the liquid surface is re-impregnated through the workbench, and the ultraviolet light is subjected to curing irradiation of the next layer, so that the layer is solidified and formed to obtain a three-dimensional solid prototype.
SLA Processes:
1. Created by 3D modeling software, the 3D model of the 12 animal heads is produced, and the stl format is derived.
2. Import the file into Magics software for slicing.
3. Import the processed 3D files into the ProtoFab SLA light-curing 3D printer for 3D printing and curing.
4. Post-treatment process of 12 animal head models by cleaning, polishing etc.
5. Painting the polished animal head model.
SLM (Selective Laser Melting)
SLM represents elective laser melting, a kind of additive manufacturing, metal powder rapid prototyping technology, which can directly form metal parts that are close to full density and good mechanical properties. SLM technology overcomes the complicated process of manufacturing metal parts by Selective Laser Sintering (SLS) technology.
The SLM technology is a technique in which metal powder is completely melted by the heat of a laser beam and solidified by cooling.
3D Printing Materials
Resins: photosensitive resin, transparent resin, translucent resin, high-precision resin, high temperature resistant resin, high toughness resin, soft rubber, etc.
Nylon: nylon + glass fiber, nylon + carbon fiber, etc.;

T-Shirt printing is a great deal of things to different people. It is a competitive income supplier to some while to others it is a passive but profitable business. Even to those who are not into venturing to this business, T-Shirt printing might still be useful. It can be a source of a pastime, an expression to those who are innovative and even be practiced for personal use.
T-Shirt printing types
There are two primary categories of T-Shirt printing, and they are the:.
Digital T-shirt printing. The digital T-shirt printing is the more contemporary and often utilized type when printing t-shirts, particularly if processing a bulk order of personalized designs. This is so as the design just have to be printed cut, and heat pressed or transferred to the t-shirt. In fact, it doesn't take a few minutes to finish one. And the result is more than any artist can be proud of. It will be exactly like the one on the computer. That is just since the art was just transferred to a printing paper for it to be transferred to the fiber or the t-shirt. This kind of printing is also meant for hobbyists or those who want to make their own personal printing press in your home.
Materials and equipment: The term digital essentially means the use of digitized devices and equipment like a computer, printer, cutter plotter, and heat press. It is also suggested that an internet connection is offered for more artwork options. For the materials, a digital printing artist should have transfer papers (light for cotton shirts, dri-fit, nylon, satin, and light colors, dark for heavily colored shirts and vinyl), wax papers, and supplies for continuous inks. The inks must be of different kinds to guarantee more kinds of fabric can be processed dye, pigment and sublimation.
The procedure: Digital T-Shirt printing is really the simpler kind of t-shirt printing since the artist or literally the printing person will only transfer an artwork from the computer, which is the precise opposite of the silk screen printing which essentially depend on the innovative artwork and cutting skill of the artist. Out of the ease of digital printing, even a novice can do the printing and embark on it as a business as long as he or she can be able to administer the transfer of artwork from the computer to the transfer paper and finally the fabric.
But for starters, digital printing will begin by printing a selected design from the computer or a photo from the files, or a custom design on a transfer paper. The artwork is now prepared and might be cut manually or with the help of a cutter plotter. Some printing presses leave the entire transfer paper for heat pressing. Although it is not wrong, the result is less commendable since the sides of the transfer paper will be visible on the shirt. The third step and the final, is peeling the top surface of the transfer paper to expose the design on a transparent like sheet then place it over the shirt and press for around 10 or more seconds. Due to the heat that the pressing might apply to the fabric, silk and all other sensitive fabrics are not good for use in digital printing.
screen T-shirt printing. The screen printing is probably the oldest kind of t-shirt printing. It is known to be a tiresome job which is why only the really innovative ones are the people that embark on this business. This kind of t-shirt printing will require real paint one made particularly for fabric printing and real skill in cutting the 'film' that will serve as the guide of the artwork that will be copied on the fabric. This is best for same design artwork since one film is good enough for an entire bulk of t-shirts. Also, it can be utilized across all kinds of fabrics.
Materials and equipment: In silk screen printing, the only materials necessary are the rough draft of the artwork, the film, cutter, a squeegee, different colors of fabric paint, and the silk screen. Most designers and artists produce their own silk screens and squeegee but school supplies always carry these materials and can be bought over the counter. The artwork and design for a silk screen print is made easier when a computer is offered, but it is not required.
Procedure: In silk screen printing, the procedure will start with the artwork. The design might be sketched, done with the assistance of a computer, or copied over the internet. This artwork will essentially serve as a guide to the film, which will be the pattern of the paint. The film is normally in color green and is available in two layers. The thicker and harder part is where the cuttings should be done which the thinner layer will be peeled off later to expose the sticky surface of the film. The number of films necessary in producing a pattern will then depend upon the complexity of the design or artwork. The more colors required in making the pattern the more the number of films to be utilized. These two is supposed to be equal. Assuming that the pattern/s is now prepared, the next step is to peel the thin layer or coat of the film. Doing so will expose a bit sticky surface of the film. To guarantee that it will stick on the silk screen face down, special liquid glue has to be applied on that side of the silk screen. Now before the liquid freeze, the film should be placed on it. As soon as the film gets solid with the silk screen, start the printing of the fabric.
Now that you know the difference and how these two kinds of t-shirt printing work, you can finally select the best for you. Whether digital or silk screen t-shirt printing, though, it is very important to guarantee the quality of the work. That way, you can be proud of the results of your hard work nevertheless difficult or easy the procedures might be.

----------------------------------------
For the first Americans, and the study of them today, it all starts with a point.
A sharp point fastened to a wooden shaft gave the hunter 13,000 years ago a weapon that could single-handedly spear a fish or work in numbers to take down a mammoth.
For a prehistoric human, these points were the difference between life and death. They were hunger-driven, handmade labors of love that took hours to craft using a cacophony of rock-on-rock cracks, thuds and shatters.
They have been called the first American invention, and some archaeologists now think 3-D scanning points can reveal more information about both the technology and the people.
The Pacific Slope Archaeological Laboratory at Oregon State University takes up only a few rooms on the ground floor of Waldo Hall, one of the supposedly haunted buildings on campus.
There are boxes of cultural history everywhere, and floor-to-ceiling wood cabinets with skinny pull-out drawers housing even more assets, but the really good stuff, evidence of the earliest known cultures in North America, lives in an 800-pound gun safe.
Loren Davis, anthropology professor at OSU and director of the lab, thinks 3-D scanning, printing, and publishing can circumvent the old traditions of the field, that artifacts are only to be experienced in museums and only handled by those who have a Ph.D.
“We are reimagining the idea of doing archaeology in a 21st century digital way,” said Davis. “We don’t do it just to make pretty pictures or print in plastic, we mostly want to capture and share it for analysis,” he added.
Nearby in the L-shaped lab, one of his doctoral students is preparing to scan a point that was discovered on Bureau of Land Management public lands in southeast Oregon.
Thousands of points have been unearthed since the 1930s in North America, the first being in eastern New Mexico near a town called Clovis. That name is now known worldwide as representing the continent’s first native people.
More recently, though, other peoples with distinctive points were found elsewhere, and some researchers think it means there was differing technology being made at the same time, if not pre-Clovis.
One such location is the Paisley Caves in southern Oregon ― one of the many archaeologically significant sites managed by the BLM.
The earliest stem point from Paisley Caves was scanned at Davis’ lab and a 3-D PDF was included in a 2012 multi-authored report in the journal Science.
Davis estimates his lab at OSU has scanned as many as 400 points, including others from BLM-managed lands in Idaho, Nevada, Oregon and Washington.
More scans would mean a bigger database for comparing points and determining what style they are.
“Ideally, we want to get as many artifacts scanned as possible,“ said Davis. “The BLM offers a lot of access to public data ― this is just another way of doing it.”

Transforming a brittle piece of volcanic glass, by hand, into a beautiful and deadly 4-inch-long spear point is a process.
In one hand would be a hard shaping rock, or maybe a thick section of antler, and in the other would be the starter stone, which in addition to igneous could be jasper, chert, or any other chippable rock that creates a hide-puncturing level of sharpness.
After what might be hundreds of controlled strokes and rock rotations, the rough shape of a lance or spear tip would take form. Discarded shards of stone would often result in more points, or other useful tools like scrapers and needles.
Clovis points are distinguished by their length, bifacial leaf shape and middle channels on the bottom called flutes. Eventually the repetitive flaking of the point would stop, and the hunter would use precise pressure points to create the flute on one or each side that likely helped slot the finished product into a spear-like wooden pole.
The hunter was now mobile and ready to roam.
---
Prior to 3-D scanning, OSU doctoral student Sean Carroll picks up a can of Tinactin, gives it the obligatory shake, and completely covers “one of the oldest technologies in North America” with antifungal spray.
The talc and alcohol from the athlete’s foot remedy helps the software see even the slightest indents in the point, and it rubs right off afterwards.
“I want to scan all the Clovis I can get my hands on,” said Carroll, who came to OSU because of Davis’ 3-D lab and is using the medium as a big part of his dissertation.
Two random items, a power plug adapter and a ball of clay, are placed on each side of the fluted point to give the camera and light projector perspective. The objects create margins that force the structured light patterns to bend and capture more of the point’s surface detail.
Even so, like the hunter rotating the shaping rock, the archaeologist has to rotate the foam square holding the three items. Each scan takes about six seconds.
Carroll and Davis estimate that the learning curve for this process was about 100 hours. One hundred hours of trial and error -- and a lot of watching YouTube videos -- for a finished product that they think is indisputably worth it.
A completed 3-D scan of a point will have about 40,000 data points per square inch. The measurements are so precise, they can determine the difference between flake marks as thin as a piece of paper.
Davis says no archaeologist with a pair of calipers can come close to measuring the data obtained via 3-D, because simply, “there are some jobs that robots are really good at.”
“If the end game is measurements, well you could spend your whole life with a pair of calipers trying to achieve what we can do in 10 minutes,” said Davis.

Last year, the famous human relative nicknamed Lucy had 3-D scans of her 3.2 million year old bones published in the journal Nature.
In 2015, archaeologists from Harvard University completed a 3-D scan of a winged and human-headed stone bull from Mesopotamia that stands 13 feet high at the Louvre Museum.
And the Smithsonian Institution is currently beta testing a website dedicated to publishing 3-D models from its massive collection, including molds of President Abraham Lincoln’s face and the entire Apollo 11 command module.
All of these new-school efforts are based upon the old-school scientific principles of preservation and promotion.
Rock points, fossils, hieroglyphics -- various forms of cultural assets are susceptible to environmental conditions and not guaranteed to be around forever. Three-dimensional scanning is the most accurate way to digitally preserve these items of merit.
Once accurate preservation is done, there are opportunities for promoting not just science, but specific research goals.
In the case of the Lucy bones, scientists hope that crowdsourcing the 3-D data will help get more experts to look at the fossils and prove that the tree-dwelling ape died from a fall.
When it comes to comparing one specific stemmed point to an entire hard drive of scanning data, BLM archaeologist Scott Thomas thinks the work being done at the OSU lab can move archaeology to a new level.
“The 3-D scanning method blows anything we have done out of the water,” said Thomas.
That ability to compare points can lead to insights on how these hunting tools moved over geography, and even expand theories about how native groups learned new technologies.
“It’s going to be a really powerful tool someday -- not too far off,” said Thomas.
While long-term data analysis may not be the sexiest form of archaeology, holding a 3-D printed stem point is a pretty cool educational tool.
Davis of OSU has incorporated 3-D prints into his classes and said his students are able to make a tactile connection with artifacts that otherwise are not available.
“The students really enjoy these printed and digital models and often say that they are almost like the real thing,” said Davis.

This spring, Davis is traveling to Magadan, Russia -- aka Siberia -- to inspect and scan some points that may be linked to Clovis peoples.
The goal in Siberia, of course, is to further expand the 3-D database. He is specifically interested in comparing them to stems from a BLM-managed site he excavated in Idaho called Cooper’s Ferry.
As his student, Carroll, begins to clean up and put the scanned points into their individually labeled ziplocked bags, Davis can’t help but mention how much easier international research could be with 3-D scanning.
“You can share cultural resource info with people in other countries and you don’t have to come visit,” he said, adding that Russia isn’t the easiest country to enter.
“It’s as easy as sending an email,” Carroll agreed.
Davis then mentioned his 11-year-old child and how much of school curriculum these days is web-based as opposed to text-based.
“There’s nothing wrong with books, I’m a huge fan of books, but it’s a different way of learning,” said the archaeology professor.
And with that, he made another point.

Best places to find 3-D archaeology online:
-- Sketchfab.com is one of the biggest databases on the web for 3-D models of cultural assets. Institutions and academics alike are moving priceless treasures to the digital space for all to inspect. Two examples: via the British Museum, a 7.25-ton statue of Ramesses II is available for viewing and free download; and via archaeologist Robert Selden Jr., hundreds of 3-D models are open to the public for study, including several Clovis points from the Blackwater Draw National Historic Site in New Mexico.
-- The Smithsonian Institution is bringing the best of American history to a new audience via their 3-D website (3d.si.edu). Amelia Earhart's flight suit? Check. Native American ceremonial killer whale hat? Check. Face cast of President Abraham Lincoln? Check and check -- there are two. And their biggest 3-D scan is still coming: the 184-foot-long space shuttle Discovery.
-- Visitors to Africanfossils.org can filter 3-D model searches by hominids, animals and tools, and also by date, from zero to 25 million years ago.
The sleek website, with partners like National Geographic and the National Museums of Kenya, makes it easy to download or share 3-D scans, and each item even comes with a discovery backstory and Google map pinpointing exactly where it was found.
