Part III · Practice

Eighteen learning
sessions

Names, causes and image characteristics can be looked up in the register and on each effect page.

Light without a camera

Comparison and first own attempts

Comparison
Cyanotype, photogram, and luminogram. Which visible traces are created by objects, and which by moving light?
Task
Sketch two image ideas without a camera. Name the process and the point where light changes the material.
Result
Two sketches, each containing one technical sentence.

Space in the flat image

Perception, perspective, and sharpness

Comparison
Stereoscopy, dolly zoom, and tilt-shift. How does each method change our perception of space?
Task
Match three causes: two viewing angles, changed camera distance with focal length, tilted focus plane.
Transfer
Choose an effect for a confining portrait and explain your choice.

3

/ 18

Making time visible

One movement, three different procedures

Comparison
Long exposure, chronophotography and bullet time.
Task
Describe a jumping body in each method. Which time points merge, which remain separate, and which camera views change?
Transfer
Design a short sequence using exactly one procedure. Note the intake and desired effect.

4

/ 18

How color gets into the picture

Material, separation and design

Comparison
Hand coloring, Autochrome, Technicolor and Duotone.
Task
Assign each term its corresponding intervention: applying color subsequently, colored filter grains, separate color extractions, targeted assignment of two printing inks.
Transfer
Choose two techniques for the same portrait. Describe the difference without using the word "vintage".

5

/ 18

Three types of image distortion

Similar surfaces, different causes

Comparison
Sabattier effect, RGB split and datamoshing.
Task
Match the following: additional light exposure during development, offset color channels, manipulated temporal video compression.
Transfer
Formulate an image characteristic for each effect. Explain why any given glitch filter only partially replicates the processes.

6

/ 18

One theme, three decades

A unique visual language instead of a collection of filters.

Briefing
A 20-second teaser for a piece of music shows only one person and one room.
Task
Choose three effects from three decades. Note their names, their historical contexts, and their role in the sequence.
Examination
What effect does something convey? Which effect could be omitted?

7

/ 18

Silver, iron and platinum

Early printing processes compared

Comparison
Salted paper print, albumen print and platinum print.
Task
Describe the surface, tone and durability of each print. Which binder or metal creates the image?
Result
A small table with three rows and one sentence per process.

8

/ 18

Ghosts and doubles

Two images in one frame

Comparison
Double exposure, combination printing and Pepper’s Ghost.
Task
Name where the second image is added: in the camera, in the darkroom or on stage.
Transfer
Plan a portrait with a transparent second figure and choose the method.

9

/ 18

Tricks of early cinema

Cuts, stops and reversals

Comparison
Stop trick, reverse motion and undercranking.
Task
For each trick, describe what the camera operator does differently while filming.
Result
Three one-line instructions for a camera operator.

10

/ 18

Building worlds

Sets that are not there

Comparison
Glass shot, Schüfftan process and miniature effects.
Task
Explain where the illusion sits: painted on glass, reflected by a mirror or built in small scale.
Transfer
Design a castle shot for a low budget and justify your method.

11

/ 18

Background behind the actor

From projection to green screen

Comparison
Rear projection, front projection and chroma key.
Task
Describe where the background image comes from and where the actor stands.
Result
A sketch of each set-up with camera, actor and light source.

12

/ 18

Colour before colour film

Painted, separated, layered

Comparison
Hand colouring, photochrom and Autochrome Lumière.
Task
Explain whether the colour is painted on, printed from separations or created by filters inside the plate.
Transfer
Choose a process for a historic travel poster and explain why.

13

/ 18

Dots and screens

Printing tone with points

Comparison
Halftone, Ben-Day dots and dithering.
Task
Describe how each method creates the impression of grey or colour from few inks or pixels.
Result
Three magnified sketches of the same grey tone.

14

/ 18

Errors as style

Glitches from video and data

Comparison
VHS artefacts, datamoshing and pixel sorting.
Task
For each effect, name the technical fault or algorithm that produces it.
Transfer
Choose one glitch for a music video and describe the mood it creates.

15

/ 18

Light in the lens

Flares, glow and blur

Comparison
Anamorphic lens flare, halation and bokeh.
Task
Explain which part of the lens or film causes each effect.
Result
One sentence per effect describing the visible shape.

16

/ 18

Seeing edges

How machines find outlines

Comparison
Sobel, Canny and Laplacian edge detection.
Task
Describe the difference between measuring the slope of brightness and its curvature.
Transfer
Choose one filter for a clean line drawing of a portrait.

17

/ 18

Depth from a single image

Maps the machine creates

Comparison
Monocular depth map, normal map and 2.5D parallax.
Task
Explain what each map or effect stores: distance, surface direction or movement of layers.
Result
A short diagram connecting each map to its use.

18

/ 18

Generating images

When the machine adds content

Comparison
Inpainting, outpainting and image-to-image diffusion.
Task
Describe what remains from the original in each case and what is newly generated.
Transfer
Plan an extended landscape poster and name the steps.
