Move the vertical slider on the right of the original photo to select the area in focus.
Use the "Preview" button to see the results, then click on the required image size and press "Download" when done to process the image and get a download link.
Site members get unlimited downloads up to 21MP (5700 pixel length/width) and can access over 50 bokeh styles, click here for details.
Processing and downloading hi-res images may take a few minutes, depending on original photo size and other factors.
A download link to the most recent hi-res file processed this session will appear in the "Recent hi-res:" area.
The size of the main selected area can be adjusted using the horizontal slider, from "narrow" (focusing on a small area) to "wide" (focusing on a larger area).
If you're using a display resolution over 1280x1024, try clicking on the "Large" button on the left to switch to large preview mode. You can then click anywhere on the image to toggle the display of the focus area selection.
Temporarily switching to large preview mode is also useful to see details in the image even if you're using a smaller display.
24 mm lens that tilts (as seen above) as well as shifts
A camera lens can provide sharp focus on only a single plane. Without tilt, the image plane (containing the film or image sensor), the lens plane, and the plane of focus are parallel, and are perpendicular to the lens axis; objects in sharp focus are all at the same distance from the camera. When the lens plane is tilted relative to the image plane, the plane of focus (PoF) is at an angle to the image plane, and objects at different distances from the camera can all be sharply focused if they lie in the same plane. With the lens tilted, the image plane, lens plane, and PoF intersect at a common line; this behavior has become known as the Scheimpflug principle. When focus is adjusted with a tilted lens, the PoF rotates about an axis at the intersection of the lens's front focal plane and a plane through the center of the lens parallel to the image plane; the tilt determines the distance from the axis of rotation to the center of the lens, and the focus determines the angle of the PoF with the image plane. In combination, the tilt and focus determine the position of the PoF.
In a subject plane parallel to the image plane, parallel lines in the subject remain parallel in the image. If the image plane is not parallel to the subject, as when pointing a camera up to photograph a tall building, parallel lines converge, and the result sometimes appears unnatural, such as a building that appears to be leaning backwards.
