What types of photos work best for AI portrait mode?

Photos with a clear subject in front of a distinct background work best. Single person portraits, pet photos, and product photography on natural backgrounds all produce excellent results. The AI works best when the subject is well-lit and clearly separated from the background. Low-contrast scenes (e.g. a person wearing white against a white wall) may produce less accurate segmentation.

Does the blur quality compare to a real DSLR?

Our bokeh effect is a high-quality simulation that closely resembles DSLR Portrait Mode blur in most standard photography scenarios. Real optical bokeh from a physical lens has unique characteristics (lens aberrations, specular highlights shaped by aperture blades) that are difficult to perfectly replicate in software. However, for social media, profiles, and general photography, the difference is imperceptible at normal viewing sizes.

我们通过映射到 f/1.2 单反镜头配置文件的Heavy Gaussian算法处理背景，将您的主体完全清晰地放置在顶部。

What Even Is Bokeh?

You know that blurry background look in iPhone portraits? That's bokeh. The word comes from the Japanese boke (blur or haze), and it refers to the quality of the out-of-focus areas in a photo, not just that they're blurry, but how they're blurry. Good bokeh turns background lights into soft, creamy circles. Bad bokeh makes everything look like smeared vaseline. Big difference.

How Cameras Actually Do This

On a real DSLR, this effect happens naturally when you shoot with a wide-open aperture (something like f/1.4 or f/2). The physics of the lens literally can't keep both the subject and background in focus at the same time. Smartphones fake it, newer ones use dual cameras or depth sensors to guess where the subject ends and the background begins, then blur the rest in software. We do something similar, except our AI model runs right in your browser using WebAssembly. No uploads, no servers, no waiting around.

It's Not Just for Faces

Despite the name "portrait mode," this works on way more than headshots. We see people using it for product photos (blurring out a messy desk behind a product), food shots (making that ramen pop against a blurred restaurant background), pet photos, and even real estate detail shots. Basically, any time your subject is fighting a busy background for attention, a little blur goes a long way.

The Privacy Thing

Uploading your selfies to a random server understandably feels uncomfortable, and it should. Most AI photo tools ship your images off to some cloud server, process them there, and send them back. Your photos, personal shots, client work, whatever, are sitting on infrastructure you know nothing about. Maybe they delete them. Maybe they don't. You just have to trust their privacy policy.

We didn't want to build it that way. Our AI model downloads once to your browser cache (it's a WebAssembly file), and from that point on, everything runs locally, on your CPU or GPU. Your photos literally never leave your device. No upload, no server round-trip, no data collection. Period.

Frequently Asked Questions

How does the AI background blur work?

Short version: a neural network runs right in your browser (via WebAssembly), figures out what's the subject and what's the background, then applies a Gaussian blur to just the background. It's modeled after the depth-of-field you'd get from a wide-aperture DSLR lens. Nothing gets uploaded anywhere.

What kinds of photos work best?

Anything where the subject is reasonably distinct from the background. Portraits, pet photos, product shots on a table, all great. Fair warning though: if you're wearing a white shirt against a white wall, the AI will have a harder time figuring out where you end and the wall begins. More contrast = better results.

Is this as good as a real DSLR?

For Instagram, LinkedIn, or a portfolio, you won't notice a difference. A real lens does produce unique optical characteristics (the way it renders light highlights, for instance) that software can't perfectly copy. But at normal viewing sizes, especially on a phone screen, the result is very close.

Why is the first photo slow?

That first run is downloading the AI model into your browser cache, usually takes 10-20 seconds depending on your connection. After that, everything in the same session is much faster since the model is already loaded locally.

Can I control how blurry the background gets?

Absolutely. Once the AI does its thing, you get a blur radius slider. Drag it low for a subtle, natural look. Crank it up for that dramatic, everything-is-melted-away effect. Play around with it. There's no wrong answer.
