When reviewing an exploratory sample, label the center and edge areas before drawing a conclusion. A single close crop may hide a difference that becomes visible across the whole piece.
Record the observation, not a promise
Use the same lighting and a wide reference photo when possible, then add a close view of the area being discussed. Note what was observed in that sample only. Do not turn one sample into a material guarantee or a claim about every future result.
