Do I need to mark the subject before describing?
No! Just describe what you want: 'add portrait mode blur with person in focus' or 'simulate depth of field on product.' The AI automatically detects your subject. Only use markers if the AI can't tell which element should stay sharp - like photos with multiple people or complex scenes.
How do I simulate iPhone portrait mode on any photo?
Upload your photo and type 'add portrait mode blur effect like iPhone portrait mode with subject in sharp focus.' The AI replicates the same depth-of-field blur that iPhone cameras create, making regular photos look professionally shot. Works on photos from any camera or phone.
Can I control how blurred the background gets?
Yes. Specify blur intensity in your prompt: 'subtle blur' for natural depth, 'dramatic blur' for strong bokeh, or reference aperture values like 'blur like f/1.4' for maximum blur or 'f/4' for moderate blur. The AI adjusts the depth effect accordingly.
