What is depth of field?
Definition
Depth of field is the range of distance in a photo that looks acceptably sharp. A shallow depth of field keeps only the subject sharp and blurs the rest. A deep one keeps most of the scene in focus.
Why it matters for sellers
Shallow depth of field helps a product stand out. A blurred background keeps attention on the item and hides clutter, which suits lifestyle shots and social posts.
For listing photos, buyers often want to inspect the whole item, so it should be sharp front to back. Close-up product shots can have very thin focus, leaving the front sharp and the back soft. Knowing this helps you decide when to blur on purpose and when to keep everything crisp.

Examples
Candle on a cluttered shelf
A seller photographs a candle in a busy room. Blurring the background keeps focus on the candle for a social post.
Close-up of a ring
A macro shot of a ring is sharp on the stone but soft at the band. The seller takes a second shot focused on the band.
Clothing on a rack
A product listing needs the garment sharp from collar to hem, so the seller keeps the whole item in focus.
Frequently asked questions
What controls depth of field?
Mainly the aperture, the distance to the subject and the lens focal length. Bigger apertures and closer subjects give a shallower depth of field.
Can a phone camera make a blurred background?
Yes. Portrait modes simulate it in software. The edges around hair or fine details can look off, so check the result.
Should a product listing photo have a blurred background?
Usually the main image should be sharp and clean. Check the marketplace's current image policy, and save blur for lifestyle or social images.
Is blur the same as a photo being out of focus?
No. Background blur is intentional and leaves the subject sharp. An out-of-focus photo is soft on the subject, which is a flaw.
