Frequently Asked Questions
What is a vignette effect and how does it improve photos?
A vignette is a gradual darkening or lightening of an image around its outer edges and corners. In optical photography, lenses naturally produce subtle light falloff toward the periphery. Adding a controlled vignette draws the viewer’s eye directly toward the central focal subject, enhancing depth, drama, and cinematic impact.
What is the difference between Radial Focus and Tilt-Shift blur?
Radial Focus keeps a circular or elliptical area around your subject sharp while gradually blurring the surrounding background in all directions. Tilt-Shift blur keeps a linear horizontal band sharp while blurring above and below, simulating the optical characteristics of a view camera lens and giving cityscapes or landscapes a charming miniature toy model appearance.
Can I change the center position of the blur and vignette?
Yes! Click the "Reposition Center" button and click anywhere on your image preview. The focal point and vignette origin will dynamically center around the exact coordinate you selected.
Does this tool resize or compress my original photo?
No. The canvas processing automatically scales to your photo’s native resolution, ensuring exported files retain 100% of their original pixel dimensions and detail.
Are my photos uploaded to any external server?
Never. All canvas operations, gradient calculations, and image encoding execute entirely inside your computer’s local browser memory. No files are transmitted across the internet.
