CGI vs product photography
Product photography wins on one-off shots of simple products that already exist. CGI wins on anything repeated, anything not yet manufactured, and anything with variants. The deciding question is not which looks better — done well both are indistinguishable — but how many times you will need to shoot the same thing.
The two cost curves
Photography is a variable cost with a low entry point: each shoot costs roughly what the last one did. CGI is a fixed cost with a high entry point and a near-zero marginal cost after it. Plotted against the number of images you need, the lines cross — and where they cross is the entire decision. One shot of one product, photography is cheaper. A range, a refresh, a set of colourways, a second season: CGI has usually already won by then, and the gap widens every time you need the product again.
What photography still does better
Real texture on genuinely irregular products — handmade ceramics, natural materials, food that has to look eaten rather than styled. Human presence: real models, real hands, real skin. Speed for something simple that already exists, where a half-day shoot beats a week of modelling. And credibility in categories where customers specifically want evidence of the actual object, not a representation of it.
What CGI does that a camera cannot
- Shoot a product that has not been manufactured yet
- Hold identical lighting across hundreds of SKUs, by construction
- Change colour, finish or material after the shot is approved
- Cut a product in half, explode it, or make its housing transparent
- Put the product in a location that would cost a travel budget to reach
- Return to the shoot months later and add an angle that was never taken
- Produce a print-resolution still and a 4K film from the same asset
The timeline difference nobody mentions
Photography is fast to execute and slow to schedule: the product must exist, be shipped, and share a date with a studio and a crew. CGI is slow to start and fast to repeat: nothing physical is required, but the first image takes as long as the model takes. For a launch, this usually favours CGI heavily — imagery can be finished while the product is still in tooling, which is the difference between launching on the date and launching six weeks after it.
Using both, which is what most brands actually do
The common answer is not one or the other. Photograph the human, lifestyle and in-use content where real presence matters; render the product itself, the variants, the exploded views and the catalogue. Renders can be matched to an existing photographic library closely enough to sit in the same grid — send the hero shots and the lighting, lens and grade get matched to them.
A decision shortcut
Count how many distinct images of this product you will need over the next two years, including every colourway, size, pack format and seasonal variant. Under about ten, and the product already exists, book a photographer. Over about twenty, or the product does not exist yet, or the range grows every season — build the model. Between the two, the deciding factor is usually whether you expect to need the product again after this campaign.
Questions
Can you tell the difference between CGI and a photograph?
Done properly, no — rendering simulates the same physics as a camera, so the same softbox, falloff and depth of field appear for the same reasons. Done badly, the giveaways are flat materials, missing caustics through glass, and lighting with no environment behind it to reflect.
Is CGI allowed on Amazon and other marketplaces?
Yes, provided the image accurately represents the product as sold. Marketplaces regulate accuracy, not technique. What is not allowed is imagery that misrepresents the product's actual physical characteristics.
Which is faster?
For a single simple shot of an existing product, photography. For a launch, CGI is usually much faster in wall-clock terms, because it does not wait for manufacturing, shipping or a studio date.
Can renders be matched to our existing product photography?
Yes, and it is a routine request. The lighting, lens characteristics and grade of an existing library can be matched so new CGI sits alongside old photography without looking like a different product.
Do we have to choose one?
No, and most brands do not. Photographing people and rendering products is the usual split, because each does the thing the other finds hardest.
