Eye Replacement

Yes — blink removal is one of the most common eye fixes, usually when a performance was otherwise perfect. Open eyes are sourced from adjacent frames of the same shot, tracked onto the closed-eye frames as a rotating sphere rather than a flat patch, and the lids and lashes are rotoscoped so they occlude the replacement correctly. The catchlight is matched so the reconstructed eye reads as alive.

The iris is tracked through the shot, isolated with a matte that respects lids and lashes, and recoloured in a way that preserves the original luminance structure and the catchlight rather than flatly tinting it. A tint that ignores the specular highlight and the shadow the upper lid casts is what makes recoloured eyes look like contact lenses — which matters if the character is not meant to be wearing any.

Yes. Beyond building the eye itself, the part that sells it is light spill: luminous eyes throw light onto the eyelids, lashes and cheekbones, and that spill has to change as the head turns and the eyes narrow. Without it the glow reads as a graphic sitting on top of the face rather than a light source inside it.

Within limits, yes. Small eyeline corrections — a gaze a few degrees off, an actor looking slightly past their mark — are routine, by tracking and repositioning the iris and pupil within the visible eye. Large corrections eventually require rebuilding the eye rather than adjusting it, because the visible sclera shape changes. Send the shot for an honest assessment before it is budgeted.
