1. Traditional Photography
Unit 15

2. Film
Coated with a gelatin emulsion that has extremely small microscopic silver halide crystals
The sizes of these crystals actually determine the contrast, resolution and how sensitive the film is.
The modern colour film consist of around 12 different layers

3. Medium Format/35mm
Basically it is a type of film gauge commonly for motion pictures and chemical still photography
35mm referes to the width of the film even though the width isn’t exactly 35mm they can be between and 35.01

4. Taking the photo
Contains a gelatin emulsion with Silver Nitrate as one of the chemical in it.
When light hits the silver nitrate it makes it into metallic silver (otherwise known as a latent image)
So when you take the photo the light will bounce of the target into the camera and the image the light produces will be captured on the film
Depending on how much light hit parts of the image will be lighter or darker

5. Processing Film
The lights have to be out as total darkness as exposure to light will effect how the picture will look are dark room like you see in old shows
Wind the film onto a reel and put it in a developing tank
To clean the film water or a non-ionic wetting agent to rinse and left to dry after that

6. Developing Developer is added:
A liquid that grows the silver in the image until they are visible
Agitate for 2 – 6 mins
Add stop bath (generally acetic acid or citric acid )
Add Fixer:
This removes unused chemicals from the film (the silver halides)
Wash and dry the film (more detail on previous page)

7. Negatives
Negatives is what the photo is referred to once it has been processed as the lightest area appear darker in the photo

8. Positive The photo appears close to what the original scene.
Can be colour or black and white.
E.g the top left image on the right

9. Negatives use We can use them to make printed photos
This is done by projecting the negative onto a photographic paper with a photographic enlarger

10. Making Prints The process is incredibly similar processing film
We use paper with silver compounds in (just like film)
Enlarging the photo is the first step in the process using either the contact process or
Develop
Stop
Fix
Wash, Dry and Finish – in old shows like some older Simpsons episode or even in Chucky they hang the photo up at the top of the room as warm air rises it will dry it quicker

11. Enlarging
By placing the negative in an photographic enlarger and projecting it onto a piece of photographic material such as glass or filmfor a fixed time (10s – 2 min) depends on the power of the enlarging agent.

12. Adjustments Burning Dodging Contrast
Similar to how you can burn and dodge images on Photoshop this is based of the actually adjustments that can be made on real photos plus the additional adjustment of the contrast which is saturation
Burning
Giving bits of the image more light – makes them darker
Dodging
Shading bits of the image – makes them lighter
Contrast
Different types of paper and developer allow contrast to be changed

13. Processing Agitate the paper in developer, till image appears
Move to stop bath tray
Agitate in Fixer tray
Wash and Finish

14. Finishing
When finished with the developing there one last step which is to add effects to it such as pressing on a glossy coating or textured surface to make it look nicer or cropping to get rid of parts of the pho that aren’t needed and take away from the focus. Another finish that can be used is mounting it

15. Colour
Much the same but takes place in total darkness as the colours are more affected on the outside light then black and white.
Enlarging is complicated because corrections are made by changing the enlarger’s light colour meaning it is a lot more pricier as you can’t just use one light for a lot of
