North light for tonal stability across long sittings
Worked from north-facing light because it never includes direct sun, keeping the modeling on a sitter's face stable across multi-day sessions.
Why it matters · A portrait painted across days under shifting light becomes a composite of hours. North light is the difference between a unified painting and a Frankenstein. Painters who accept any light produce inconsistent values across the same face.
Use the studio camera for the skeleton, not the spirit
Kept a studio camera and used it to capture initial proportions — distance between eyes, curve of nose, foreshortening of an arm — so painting energy could go to spiritualization rather than mechanical likeness.
Why it matters · Photography is a tool, not a master. Kramskoy's instruction was to know what the camera is for (proportion, pose-reference, structure) and what it is not for (life). Painters who use photographs as the painting produce dead paintings; painters who refuse photography spend their energy on what photography handles.

Start every portrait with the eyes
Believed if the eyes were not right the rest of the painting was a waste of time; brought the eyes to a state he trusted before resolving anything else on the face.
Why it matters · A portrait's reading depends on the eyes. Painters who finish the face systematically and arrive at the eyes last have to redo everything if the eyes do not hold. Kramskoy reversed the order — earned the eyes first and let the rest hang from them.
Local-finish discipline
Worked in sections — brought the face to a high degree of finish before blocking in the background or clothing. Treated each passage as a local problem to be solved completely before moving on.
Why it matters · Most painting teachers preach global correction — keep everything at the same stage. Kramskoy worked the opposite way. The discipline of finishing locally is harder but produces a different relationship between figure and ground. Painters who only ever work globally never learn the trade-off.
Cast the type, then paint
For historical and religious works sought specific real types whose faces matched his intellectual vision of the character — a Christ in the Desert required a face that could carry that subject; a Mina Moiseev required a peasant whose specificity could not be invented.
Why it matters · A character type has to exist in the world before it can exist in the painting. Casting is part of the painting, not preparatory to it. Painters who invent faces produce stock characters; Kramskoy found them.
