Variation is not chance
Variation is not randomness. A coherent series protects a few anchors while allowing controlled movement elsewhere. If everything changes, identity disappears. If nothing changes, one idea is merely repeated.
Define invariants, variables, and ranges before producing many images.
Six decisions before you make anything
Choose what must stay stable: palette family, framing rule, material, question, or type behavior.
Select what may change: subject, scale, viewpoint, density, weather, gesture, or sequence.
Define how far each variable can move before the system breaks.
Plan one meaningful difference between neighboring works.
Edit for the strength of the series, not attachment to individual images.
Order works so repetition builds expectation and variation changes its meaning.
Create a six-image matrix with two fixed rules and two variables. Change only one variable between neighbors, then identify where family resemblance breaks.
