Can AI photography create a realistic depth of field or bokeh effect?

Quick Answer

Yes. AI image tools can simulate aperture-style background blur (f/1.8, f/2.8) and produce convincing bokeh. The realism gap is usually not the blur itself but how cleanly the product edge is held: generic tools tend to soften the product along with the background. Nightjar is built around product preservation, so the bokeh sits behind the product instead of bleeding onto it.

How it works

Depth of field (bokeh) in real photography is a function of lens, aperture, and focus distance. AI photography simulates the effect by separating the product from its background and applying a graduated blur to everything behind the focal plane.

Subject isolation: the model needs to identify the product edge cleanly. If this step is weak, the blur "bleeds" onto the product.
Depth-style blur: a graduated blur is applied so distant elements blur more than near elements, mimicking a physical lens.
Photographic direction: the camera feel (shallow depth, longer focal length, soft background falloff) belongs to the overall look of the image, not a single slider.

In Nightjar, the camera feel is set through a Photography Style: a reusable visual direction that controls camera, lighting, mood, color, and atmosphere together, so you do not have to re-describe the lens in every prompt. A Photography Style with shallow depth language (macro product, portrait-style close-up, editorial telephoto) carries that lens behavior across every image you generate with it.

Generic AI vs. product-first AI

Behavior	Generic AI (Midjourney, DALL-E, ChatGPT)	Nightjar
Product edge	Often softens the product along with the background	Designed to preserve the product edge while blurring the scene
Bokeh control	Buried in prompt language, varies image to image	Set by the chosen Photography Style and reused across image generations
Catalog consistency	Drifts between images	Same focal feel across the whole catalog when the same Photography Style is reused

Pro tip

For small products (jewelry, cosmetics, watches, eyewear), pick or build a Photography Style with macro or portrait camera language. The shallow depth of field comes out of the style itself, so the product reads sharp against a soft background without having to re-prompt every image. To carry that look across an entire catalog, save the full Create-form setup as a Recipe, a Nightjar-saved combination of Photography Style, Composition, background, and output settings, and reapply it to the next product without rebuilding the brief.
