As photography became more and more advanced, the need to take photographs on the battle field was a growing need for the military of the United States and other European countries. In order for a camera to be effective in a war, it must be rugged, reliable, have excellent optics, and portable. If there was one country that was already good at making cameras like this, it was Germany. The problem is that Germany was the country that was on the other side of the looming conflict, so being able to rely on their technology was not going to happen. There was an abundance of large format plate cameras that had great lenses and could produce excellent images, but they were very big and not portable. Plus, their increased size and complexity meant they would not stand up to the abuse that a camera might encounter during a war. There were folding, box, and TLR cameras that all could use medium format roll film and were relatively small, but each of them had their own sets of challenges.

A History of Photography Part 1: The Beginning
This primitive method captured images onto small silver-coated copper plates, producing just one permanent, irreproducible print. Already in November of , an agent arrived in New York City to sell equipment for producing daguerreotypes. Within a few years nearly every city and small town had a photography studio, and rich and poor alike flocked to sit for their portrait. Exposure times for early photographic processes were quite long, and portraits often contain blurred images of sitters moving a head or an arm.

This has changed over the past few decades because of the dramatic advances in digital imaging technologies and computer power. One of the best examples of this was the computer artistry of Ray Downing, whose digital re-creation of Jesus based on the Shroud was documented in “The Real Face of Jesus” program that appeared on the History Channel. In the past few years, digital artists around the world have been able to render their own interpretations of how Jesus may have appeared based on the Shroud and these show up from time to time on the internet.
However, throughout all those years, not one artist has attempted to create an interpretation of what Mary, Mother of Jesus looked like based on the Shroud image. Until now, that is. In July of my good friends Bill and Belenna Lauto directed me to the website of digital artist Dean Packwood in Taupo, New Zealand and shared his beautiful, photorealistic rendition of Mary, Mother of Jesus with me. Dean chose the Shroud of Turin image as the structural basis for his truly beautiful, completely digital artwork and I wanted to share it with you.

Sunday, March 18, Dating Old Photographs: Example 2 Crayon Enlargement This is one I found in an antique store recently. It is actually a crayon enlargement, which was an enlarged copy made of a cabinet card or carte de visite. The trouble with enlargements of such photos was that the results often weren’t very clear, so the artist or photographer would then enhance it by drawing over it with other materials like charcoal or pastels.
Sometimes, such as in this case, it would be colorized, but that was not always the case, there are many black and white crayon enlargements. Either way, the effect of the enhancement typically makes the image look almost more like a drawing or painting than a photograph, but at the same time, certain elements appear too realistic to not be a photograph.

The exception here is among private-sector nonunion women who have a high school diploma or less education. For this group, annual median wages for much of the past decades have been relatively flat. And by , women with only a high school diploma or less education had seen their wages drop below levels that prevailed in Yet these explanations ignore a vital contributing factor: Unions and their effects on wage trends have been studied, but the research focuses on how the shrinking number of private-sector union members reduces the wage gains that accompany membership.
Officially the private-sector unionization rate is 6. The erosion was even larger among men without a college degree, falling from 38 percent to 11 percent. Union membership was not as high among private-sector women as men in , just 16 percent, so the drop by to 6 percent was not as severe the fall among non—college graduate women was the same. As a large body of work documents, unions raise the wages of their members, especially private-sector members, relative to nonunion workers.
Thus deunionization—the erosion of the share of workers who belong to a union—has directly contributed to wage stagnation by reducing the fraction of the workforce receiving the union wage premium. In this report, we take a different approach to the issue of union decline and wages. We contend that unions, especially in industries and regions where they are strong, have indirect effects on wages, helping to establish pay and benefit standards that many nonunion firms adopt.
We begin in for two core reasons. First, research documents a sharp increase in earnings inequality starting around
