Burning-in-is the process of adding more light to a particular area during enlarging.
Composition- is the way in which all the elements in a photograph are arranged.
Contact prints-to make it easier to tell just what is on a roll of film.
Depth of field-refers to how much of the field of view, from front to back, remains in focus.
Dodging-lightning a dark area to improve detail.
Exposure Control- it must be the right amount of light.
F-Stops-the different size openings created this way are called F-stops.
Inverse square law-is any physical law stating that some physical quantity.
Projection printing-is making prints by projecting light through the negative onto a sheet of photographic paper.
Rule of thirds- divides the viewing area into thirds both vertically and horizontally.
Safe lights- have coatings that filter out certain colors of light.
Spot retouching-dust spots can be painted over with a gray spotting solution.
Step test- is a test made to save time and photographic paper by exposing

Questions
1-What is composition and how it can improve a photograph?
Composition is the way in which all the elements in a photograph are arrange. It improves it by arranging the elements.
2- When should a tripod be used to avoid blurring a picture?
When a camera is slower then 1/60 of a second , a tripod should be used.
3- Describe three ways lighting can be altered to improve a photograph?
When taking photos outside it is a good idea to keep the sun behind the camera or to the side. This limits the glare that can appear in the picture and ruin it. On the other hand, dramatic results can be achieved by silhouetting a subject. The subject is dark and without visible detail against a bright light. This is done by locating the subject between the sun and the camera at sunrise or sunset.
4-What is depth of field and how is it achieved? Depth of field refers to how much of the field of view, from front to back, remains in focus. A small aperture, f/22 for instance, creates a large depth of field - that is close to the to the camera as well as objects far away are in focus.
5-When might you use a shutter speed of 1/1000 of a second?
You might use it to photograph a runner it will freeze the runner in its place.
6- When can a light meter be misleading?
When a dark subject is against a bright background. The meter will read the bright background and the resulting photograph will be a silhouette of the subject.
7-Name the seven steps in film processing.
Step 1 loading the film, Step 2 developing the film, Step 3 stopping development, Step 4 fixing the image, Step 5 wash the film, Step 6 Wetting the film, Step 7 Drying the films made to save time and photographic paper.
8-What is a contact print and what is it used for?
It is used to make it easier to tell just what is on a roll of film that is contact print.
9-What is burning in and how does it differ from dodging?
If the area is to light it may be corrected by burning -in. It is to add more light. To
darken a light area is dodging, It is to add more darkness in the picture.
10-How is film animation created today?
It is now created with computers and models.
