The word that matters is consistency. A catalogue is viewed as a grid, so a shopper sees dozens of products at once. If the light, background or model changes from one row to the next, the brand looks smaller than it is. Catalogue work means holding one look steady across a whole range and several seasons.
A typical set per product covers front, back, side and detail views, often on a model, with a packshot for the main listing. Volume is the challenge: new drops, restocks and colourways keep arriving, and each one has to match what is already live.
