Summary: CGI pays off with many variants, products that aren't yet deliverable, and recurring catalog productions. Photography remains stronger for emotion, people, and one-off pieces. In practice, professional productions combine both techniques.
One of the most common questions from marketing leads: should we photograph our products or render them? After more than fifteen years in image production – first as an advertising photographer, today as managing partner of a studio that offers both – my answer is: it's the wrong question. The right one is: what job does the image need to do?
What is CGI in image production?
CGI (Computer Generated Imagery) refers to photorealistic images created entirely on a computer. A scene is built from CAD data or 3D models, lit with digital light, and rendered. At its best, the result is indistinguishable from a photograph.
When CGI is superior
- Many variants: a kitchen in twelve front colors and three countertops? Twelve builds in the studio – one click in CGI.
- The product doesn't exist yet: catalogs are often produced before series production starts. CGI makes products visible before they exist.
- Consistency over years: the same scene can be restocked with new products year after year – same light, same perspective, same visual language.
- Logistics: no transport, no setup, no damage. A huge cost factor for large or heavy products.
When photography is superior
- People and emotion: as soon as hands, faces, and real use come into play, photography is faster and more credible.
- One-off pieces and surfaces with character: natural materials, patina, handcrafted details – the effort of rebuilding them digitally often outweighs the benefit.
- One-off motifs: for a single image with no need for variants, the modeling effort of CGI is rarely justified.
The practice: hybrid
Most of our productions today are hybrid. Photographed sets get populated with rendered products, CGI scenes are enriched with photographed props, and generative AI speeds up variants and retouching. The viewer doesn't see the difference – and that's exactly the point.
Conclusion
CGI and photography aren't competitors, they're tools with different strengths. The decision shouldn't be ideological but based on the need for variants, product availability, emotional weight, and budget. A good studio advises with an open mind toward the technology – and masters both.
