Depth of field
The range of distance in an image that appears acceptably sharp, controlled by aperture, focal length and distance.
Depth of field in jewelry photography
Jewelry is small, so photographers work very close to it. At macro distances depth of field becomes extremely shallow, sometimes only a few millimetres, which is why studios use focus stacking, combining many photos focused at different depths, to get a whole ring sharp.
In renders
Renders do not have that limit. A virtual camera can keep everything sharp, or simulate depth of field on purpose. The choice should follow the job of the image:
- Product pages and marketplaces usually want the whole piece sharp, so buyers can inspect details.
- Lifestyle and mood images can use shallow focus to guide the eye to the centre stone and soften the background.
Getting it right
If you blur, keep the focus on the most important part, usually the centre stone or the front prongs. Blurring the stone itself is the most common mistake. Keep the blur natural, because very strong blur on a small object makes it look like a miniature model.
AI photoshoots
AI lifestyle images often add a shallow background blur, which helps separate the jewelry from a hand or a scene. Check that the jewelry itself is sharp and pick the result where the piece is in focus. Our guides cover product image planning in more depth.
