Answer:
Blind contour drawing is a drawing exercise, where an artist draws the contour of a subject without looking at the paper. The artistic technique was introduced by Kimon Nicolaïdes in The Natural Way to Draw, and it is further popularized by Betty Edwards as "pure contour drawing" in The New Drawing on the Right Side of the Brain. Nicolaïdes and Edwards propose different ideas of why blind contour drawing is an important method of drawing for art students. Nicolaïdes instructs students to keep the belief that the pencil point is actually touching the contour. He suggested that the technique improves students' drawings because it causes students to use both senses of sight and touch. Edwards suggests that pure contour drawing creates a shift from left mode to right mode thinking. The left mode of the brain rejects meticulous, complex perception of spatial and relational information, consequently permitting the right brain to take over. Blind contour drawing may not produce a lifelike drawing; however, it helps students to draw more realistically, rather than relying on their memorized drawing symbols. Blind contour drawing trains the eye and hand to work as a team, and it helps students to see all of the details of the object.
Some artists use contour drawing to warm up for a drawing session.
Answer:
Photography has come a long way in its relatively short history. In almost 200 years, the camera developed from a plain box that took blurry photos to the high-tech mini computers found in today's DSLRs and smartphones.
The story of photography is fascinating and it's possible to go into great detail. However, let's take a brief look at the highlights and major developments of this scientific art form.
The First Cameras
The basic concept of photography has been around since about the 5th century B.C.E. It wasn't until an Iraqi scientist developed something called the camera obscura in the 11th century that the art was born.
Even then, the camera did not actually record images, it simply projected them onto another surface. The images were also upside down, though they could be traced to create accurate drawings of real objects such as buildings.
The first camera obscura used a pinhole in a tent to project an image from outside the tent into the darkened area. It was not until the 17th century that the camera obscura became small enough to be portable. Basic lenses to focus the light were also introduced around this time.
Answer:
The high salt content in a mannitol salt agar plate helps to separate pathogenic Staphylococci from bacteria and fungi in a mixed sample
Explanation:
Mannitol Salt Agar is a selective culture medium. It is used when you have a biological sample, or a food, contaminated by various bacteria or fungi, but the researcher wants to know if this sample has colonies of pathogenic Staphylococci.
Staphylococci colonies are resistant to the presence of salt in the culture medium, so they survive in this medium. The pathogenic Staphylococci consume mannitol and have a large colony surrounded by a yellow zone. After seeing this colony, the researcher can isolate it and study it correctly.
