Effect chains

An effect chain applies several operations in sequence, with each operation reading the previous result. Changing the order can change the image.

Inspect the image between two operations.

Loading the experiment…

A changing cutoff reveals why blur before threshold differs from blur afterward. Use any control to take over.

What to try
  1. Follow the source through stage 1 into stage 2 and change the threshold or blur radius.
  2. Swap the stages, then bypass stage 1. Compare with the small result showing both operations in the opposite order.

What to look for: A threshold removes intermediate tones. Blurring afterward creates new intermediate values, while thresholding last leaves only the two chosen colors.

How it works

An edge detector followed by thresholding emphasizes different information from thresholding followed by edge detection. A nonlinear step such as quantization can discard values that a later adjustment cannot recover. This is why a list of effect names alone is not a complete recipe.

A repeatable chain needs operation order, parameter values, seeds and the same input. Seeded generators reproduce their random choices, but dimensions and earlier processing also affect their result. A cashier preset is one saved recipe; it does not define the entire algorithm family.

Use it in the Lab

In the Lab, record a sequence while generating and processing an image. Save the chain with a meaningful name. Replaying it commits one undoable operation, making it easy to compare recipes.

Limits & distinctions

A chain is only reproducible with compatible input and settings. Saved browser presets are local; download the project when the composition itself needs a portable backup.
