And, the answer for the the question is :
Explanation:
Scientists spent a lot of time and effort trying to figure out how to capture true colour in photographs. Auguste and Louis Lumière, French pioneers, developed autochrome, the first practical approach to colour photography. First introduced in 1907, autochrome produced colour photographs by passing light through plates coated with minute grains of green, red, and blue potato starch.
Potatoes are not only a staple food in many cultures around the world, but they also played a crucial role in the development of early color photographic prints. This might come as a surprise to many, but potatoes were actually used as a key ingredient in the process of creating color photographs in the early 1900s.
The process of creating color photographs was a complex and time-consuming one in the early days of photography. Before the advent of modern color photography, photographers had to rely on various techniques to create color images. One of the most popular methods involved using a combination of three primary colors: red, green, and blue. By layering these colors on top of each other, photographers were able to create a full-color image.
However, creating these color separations was no easy task. It required a great deal of skill and expertise, as well as expensive equipment and materials. This all changed with the discovery of a new technique that involved the use of potato starch.
The process of creating a color photograph using potato starch involved creating a color separation negative for each of the primary colors. This was achieved by mixing potato starch with a dye of the corresponding color and then spreading it onto a glass plate. Once the starch had dried, it was then exposed to light through the original black and white negative.
The starch acted as a filter, allowing only light of the corresponding color to pass through and exposing the plate beneath. This process was repeated for each of the primary colors, resulting in three separate color separation negatives.
These color separation negatives were then used to create a full-color image. The process involved layering the three negatives on top of each other and then exposing a final piece of photographic paper to the combined images. This resulted in a full-color photograph that was remarkably accurate and, most importantly, much easier to produce than previous methods.
The use of potato starch in the process of creating color photographs revolutionized the industry. It made color photography more accessible to a wider range of people, and it also paved the way for further developments in color photography. Today, we take color photographs for granted, but it is important to remember the pioneering work of early photographers and the role that potatoes played in their successes.
potatoes were instrumental in the development of early color photographic prints. By using potato starch as a filter, photographers were able to create accurate and beautiful color images that were much easier to produce than previous methods. This discovery revolutionized the photography industry and paved the way for further advancements in color photography. It is a testament to the ingenuity and resourcefulness of early photographers and the humble potato.
