Low-Key and High-Key lighting

Low-Key lighting - Low-key lighting is a styled of lighting for photography. Low-key lighting often uses only one key light, optionally controlled with a fill light or a simple reflector. Low-key light accentuates the contours of an object by throwing areas into shade while a fill light or reflector illuminates the shadow areas to control the contrast. http://en.wikipedia.org/wiki/Low-key_lighting

Hight-key lighting - High-key lighting simply refers to images that are mostly bright, with a range of light tone and whites and not very many blacks or mid-tones. In hight-key photography, tones that generally would have been mid-range become white ans white becomes, well,white. http://www.digital-photo-secrets.com/tip/3558/using-lighting-style-to-create-mood-high-key-and-low-key-lighting/

Aperture and shutter speed 

Aperture: f2, f2.8, f4, f5.6, f8, f11, f16, f22, f32

Shutter speed: 1 sec, 1/2 sec, 1/4 sec, 1/8 sec, 1/15 sec, 1/30 sec, 1/60 sec, 1/125 sec

Shutter speed

What is shutter speed?

Shutter speed is the length of exposure when using a camera. Each shutter value represents a "stop" of light and it is measured in fractions of a second. The faster the shutter speed the more detail in the picture is shown.

Health and Safety notes

When using mixed toners make sure you wear gloves to avoid the skin from irritating, goggles are meant to be worn, and use in a well-ventilated room. Make sure you rinse prints well between bleaching & developing so the risk of skin being damaged is minimised.  

When mixing toners you need to wear gloves, goggles and respirator. Mix the powders in glove box when possible. A good ventilated room is required here. Make sure that sulfide or selenium toners aren't contaminated with acids as this is dangerous.  

1:1 Printing Step by Step guid 

1.  Set up enlarger ready for printing. Adjust the height of the enlarger head to
