Explain the process you keep assuming is obvious.
Show the route from raw material to finished product, illustrate a hard-to-film stage or organise existing footage into a clear sequence. Technical details are agreed before production. If your explanation relies on “everyone knows this”, bring someone who does not. They are suspiciously similar to your customer.
Instructions for people outside your own head.
Installation, assembly or use broken into steps, with labels, close-ups and subtitles where helpful. Your subject expert checks the instructions before release. A viewer should be able to follow the sequence without the running commentary you forgot to include. The dramatic logo reveal can wait until the bracket is the right way round.
Your brochure is not an archive of internal politics.
Specifications, diagrams, photographs and instructions arranged so the reader finds the answer. Screen, print and language versions are scoped. Every department may want a page. The customer has not promised to read them. Include what helps the decision or the task, with accurate details and a usable order.
A photograph with a little more room.
Add depth and restrained movement to a room or product photograph. Wider panoramic visualisations may need more images or a floor plan. Reconstructed views are labelled and checked against references. No, making the room look twice as large is not “aspirational”. It is a different room.
Bring the material. Save the adjectives.
Representative images, existing footage, a process description or a question people keep misunderstanding are enough to start. Agree the format and outline, then review a sample before the full set. Concrete feedback gets a concrete revision. “It needs more energy” gets a follow-up question.
Generated and illustrative sequences need agreed labelling. Product details, dimensions and instructions are checked against sources. “Nobody will notice” is not a technical approval. The finished material must represent the thing you actually sell.
