2. Johannes Vermeer van Delft, b. October 1632, d
Johannes Vermeer van Delft, b. October 1632, d. December 1675, a Dutch genre painter who lived and worked in Delft, created some of the most exquisite paintings in Western art.
His works are rare. Of the 35 or 36 paintings generally attributed to him, most portray figures in interiors. All his works are admired for the sensitivity with which he rendered effects of light and color and for the poetic quality of his images.

5. Pinhole Vocabulary Camera- optical instrument that records images
Negative- image in which the lightest areas of the photographed subject appear darkest and the darkest areas appear lightest
Positive- light background and darker active segments
Landscape- visible features of an area of land, foreground , middle ground , background
Still life - is a work of art depicting mostly inanimate subject matter, typically commonplace objects which may be either natural (food, flowers
Portrait- a picture of a person
Lens- an optical device which transmits and refracts light, converging or diverging the beam
Aperture- a hole or an opening through which light travels
Exposure- amount of light allowed to fall on each area unit of a photographic medium
Images- artifact that depicts or records visual perception, for example a two-dimensional picture
Scanner-converts text, drawings and photographs into digital form that can be stored in the computer system
Adobe Photoshop- Adobe Photoshop is a graphics editing program developed and published by Adobe Systems.

6. Pinhole Vocabulary
Developer - chemical that makes the latent image on the film or print visible. It does this by reducing the silver halides that have been exposed to light to elemental silver in the gelatin matrix. The longer a developer is allowed to work, the greater the degree of reduction of the silver halide crystals to silver and therefore the darker the image. (2.5-3min)
Stop bath – an acid that stops the developing process (30sec)
Fixer- chemical that makes your image permanent (2 min.)
Print washer- sink that washes excess chemistry off your prints, with a constant flow of fresh water
Photographic paper- a paper coated with a light-sensitive chemical formula, used for making photographic prints. When photographic paper is exposed to light it captures a latent image that is then developed to form a visible image. The light-sensitive layer of the paper is called the emulsion
Light sensitive- ability of a substance or a material to change its properties under the influence of the visible light

7. developer stop bath fixer 3 basic chemicals
Always In this order for film and paper

8. 2. Dev causes emulsion to swell for better absorption of developer
Developer changes exposed silver salts into black metallic silver that can be seen (gelatin silver print)
Emulsion- dull side of film
More fragile when wet
Emulsion contains your image
1. Dev absorbs chemicals released during the change of salts to metallic silver
2. Dev causes emulsion to swell for better absorption of developer

9. Stop bath= 30sec. Neutralizes, prevents further development of film.
Weak acid solution – after developer
Acetic acid
Color indicator- yellow to purple

10. Fixer Fix dissolves all unexposed silver salts in the emulsion
Makes images permanent!
After fixing, film no longer reacts to light.
Image can be seen
Sometimes called “HYPO” sodium hyposulphite/ammonium thiosulphate rapid fixers, works faster

11. Darkroom Etiquette Use tongs in trays, keep tongs in the right tray.
Work carefully at the sinks.
Use trays to carry prints to sink to into classroom.
Do not waste paper!
Use caution when near chemistry.
Clean up spills and tell Mrs. Martin
Wash hands at the end of class in big sink.
Failure to follow these rules will result in removal from lab, referral and call home.
