Camera types and focal length

Camera types: 


35MM slr 

single-lens reflex camera (SLR) typically uses a mirror and prism system (hence "reflex", from the mirror's reflection) that permits the photographer to view through the lens and see exactly what will be captured

Medium format

Generally, the term applies to film and digitalcameras that record images on media larger than 24 by 36 mm (full-frame) (used in 35 mmphotography), but smaller than 4 by 5 inches (which is considered to be large-format photography).

Bridge camera

Large Format

A large format camera is bigger then a medium format camera 

Polaroid

material in thin plastic sheets that produces a high degree of plane polarization in light passing through it.

Twins Lens reflex

A twin-lens reflex camera (TLR) is a type of camera with two objective lenses of the same focal length. One of the lensesis the photographic objective or "taking lens" (the lens that takes the picture), while the other is used for the viewfinder system, which is usually viewed from above at waist level.

Camcorder

a portable combined video camera and video recorder.

DSLR

is a digital camera combining the optics and the mechanisms of a single-lens reflex camera with a digital imaging sensor, as opposed to photographic film.

Lomo - iomography

Compact Camera

a small, simple 35 mm camera with automatic focusing and exposure.

Mobile Device

The iPhone 4 has a 4.1 mm lens. Has auto focus, tap to focus, f/2.4 aperture. The iPhone is a portable camera and can adjust to the night/ low light, generally have an alright zoom range but the quality of the image is decreased when zoomed in.

Macro: Lenses for Insect, plant and flower photography. Lenses to photograph flowers, insects and other close or near subjects

Tilt and Shift (TSE): Lenses for photographing buildings, Keystoning and correcting perspective, for making Tilt and shift photos and video.

Wide angle lenses and zoom: Canon, Nikon, Sony, Pentax and Panasonic wide angle lenses for photographing landscapes and documentary and capturing vistas

Standard prime and standard zoom lenses: General use lenses for Portraiture, Events, Editorial and photo journalism and Wedding photography

Telephoto Prime and Zoom: Telephoto prime and zoom lenses for action and Sports Photography, Wildlife Photography , Events Photography and Journalism.

Ultra wide angle: 14mm-20mm

Collograph - Technical Notes

Making Collagraph plates

The word 'Collagraph' is derived from the Greek word meaning glue and graph. It is a combination of two words of 'Collage' and 'Graphic' implying a connection between the method of construction and printing of an image. It is a collage print making technique, where the image is composed from a variety of textured materials, glued to a cardboard base. The two most important things to remmeber are;

Materials used must be flat, or almost flat materials being used must not have any sharp edges.

Equipment

Board, PVA glue, moulding paste, carborundum, sand, glue gun, textured materials, textured wallpaper, card/paper, shellac, watercolour paper, blotting paper, caligo safewash relief inks, tissue paper & newsprint, scrim, toothbrushes, albion printing press, etching press

Collagraph can either be relief or intaglio.
Print each of your of 3 plates to see what effects the materials used create when printed.

Mix the inks using a palette knife on a perspex board.

Tip: Explore a limited colour palette of 2-4 colours.

Step by step

Inking up the plate

1. Select your inks and mix a 5p size amount
of ink with an equal amount of extender depending on the quality of the ink.

2. Apply a small amount of ink to the desired area using scrim or a toothbrush. Do not over
ink the plate. Ensure you rub the ink into all of the crevices.

3. Take a piece of tissue paper a lightly buff
the surface of the plate, and clean the edgesof the plate.

Printing the plate

1. Soak watercolour paper in water, use blotting paper and blott off any excess water.

2. Lift up the blankets on the etching press

and place the collagraph plate face up. Lay

the watercolour paper on top of the plate and

lay the blankets over the plate and paper.

3. Roll the plate and paper through the

etching press. Carefully lift the print away

from the plate at the corner.

4.Clean the plate with warm soapy water, dry

plate before next use.

Health and safety; 

Careful not to get ink anywhere on your clothes or in your eyes, also when press printing look what you are doing at all times. Wear protective clothing gloves & apron, keep room well ventilated


Glen Alps:

Was born in Colorado, America in 1914 and died in 1996. He was a

print maker and educator who has been credited with having developed the technique and naming it Collagraph.


Here is some of Alps work. I like this piece as he has used two lots of colours also the lines are in different colour.

Graffiti - Health and safety

Spray paint is highly flammable this means you should not use a naked flame anywhere near spray paint as it can set alight.

You can absorb spray paint into your body by inhaling them, swallowing them or absorbing them through the skin. Inhalation is the most common way of

poisoning yourself since materials can be in the form of dusts or powders, sprays and mists, or vapours and gases. Since we are all being affected by thousands of chemicals in our environment 24/7, it makes sense to try to minimise this where we can. You can reduce the chances by staying it in a well ventilated are, wearing gloves, goggles and a breathing mask.

screen printing health and safety tell a story

Screen Printing

equipment needed; spoon, acrylic paint, acrylic medium, squeegee, packaging tape.

The screen is made from a fine mesh material which is fixed to a metal frame. A stencil is placed under the screen and ink is forced through the stencil on to the material below. Screen printing with stencils is best for blocks of colour.

Firstly your postive film positive used will be exposed and will harden the light sensitive emulsion on to the tight fabric which is already on the metal frame, then you have to tape upp all the yellow areas and the sides of the metal frame. Once you have done this you can then put your mix of acrylic ink with acrylic medium on to the top of the frame and then squeege the ink across the screen stencil foricing the ink through the open areas, then lift your frame back up and squegee ink back across to keep the screen wet otherwise it will dry up.

Health and safety 

-DO NOT EAT OR DRINK around the area you are doing print or within the room.

-The Paint is toxic

-Do not use the same containment colours

- Clear up water when you have washed your screen

-When mixing Acrylic with medium, if medium get on your hands, wash hands as soon as possible!

-Make sure your bag is out of everyones way, to prevent people from tripping for example 

-Doing to much printing, can hurt your arm, as your using alot of muscle. Take regular breaks or do something else that is light.
