Listed below are the light fields in our archive. For each light field, there is a link to the imagery - sometimes in several forms, and sometimes accompanied by calibration information. Following this is a link that allows you to view the light field in your browser using our Flash-based light field viewer.
In most cases you shouldn't need to download any software to use our viewer; just click on the indicated links below. Be warned though, this involves loading the entire light field (usually at slightly reduced spatial resolution) into memory. For the largest light fields, this involves downloading about 30MB of data, and will cause your browser to use up to a gigabyte of RAM. Firefox 3 uses notably less RAM than Firefox 2 when viewing these light fields, as does Internet Explorer 7. Safari and Opera should also work, with the appropriate flash player plugin.
You're free to take the viewer and use it for your own light fields. The source code and instructions for the using or modifying viewer are available.

Diffuse bunny with well-known geometry. The angular spacing is quite narrow, so this light field appears to be correctly antialiased (no ghosting when using a large aperture).

Jelly beans of various colors at various depths. Simple geometry with some texture and specularity.

A lego scene. Contains relatively simple geometric objects at various depths. The lego is slightly specular, and untextured in many places, making depth reconstruction more challenging than you would expect for this scene. The regular grid of studs on the base plate provides a good demonstration of synthetic focus.

A scene with a crystal ball resting on tarot cards. The ball acts as a lens. The cards act as diffuse textured objects at many orientations and depths. This light field is captured at larger angular extent than the next one, and hence contains more angular aliasing - this is good for depth reconstruction but bad for refocusing.

The same scene as above, captured with smaller camera spacing. This has less angular aliasing, and is hence better for refocusing and worse for depth reconstruction. The camera is at F/8 at 22mm, so the size of the aperture was 2.75mm. The spacing between two camera positions was just under half of this (roughly 1.33mm).

A chest with gemstones, coins, and jewelry spilling out. Contains highly complex specular geometry at a fairly high resolution. Also contains some translucency. All jewelry courtesy of Elena Adams.

The lego gantry capturing itself, looking in a mirror. The gantry naturally moves as it captures itself, which results in some unusual apparent depths for each object. Furthermore, the gray towers move vertically but not horizontally, giving them one apparent depth from horizontal parallax, and a different depth from vertical parallax. The focus is hence astigmatic. More usefully, panning the scene shows all the positions the lego gantry moves through.
The light fields in this section were acquired by Marc Levoy. More detail on these datasets can be found at the Light Field Microscope page. Some things to be aware of when viewing these light fields using the Flash-based viewer:
You can also view these light fields using LFDisplay, our hardware-accelerated viewer for microscope light fields. This viewer requires downloading an executable, but it won't have the resolution limitations of the Flash-based viewer.

The specimen is a 200-micron-tall "tower" of fluorescent crayon wax. The objective is 20x/0.5 (dry), used without a cover slip. The parallax you see in this light field is normally unavailable to the microscopist, who only sees a single, orthographic view of the specimen.

A Golgi-stained slice of rat brain (courtesy of Shinya Inoue, Marine Biological Laboratory), imaged with a 20x/0.75NA (dry) objective. Lateral spatial resolution on the specimen is 1.5 microns. Angular resolution is about 5 degrees. In other words, when panning across the light field in pinhole mode using our Flash-based viewer, each step is 5 degrees.

The same slice of rat brain as above, imaged with a 40x/1.3NA oil immersion objective. Note the large amount of parallax in this light field. A 1.3NA objective can capture rays leaving the specimen at angles up to 59 degrees on either side of the optical axis. For photographers, this would correspond to a lens having a relative aperture of f/0.58 - far faster than any commercially available photographic lens.

This light field is identical to the previous one except that dense foliage was placed in front of the humvee and soldier. The exposure time was also increased and lights turned up slightly to avoid dark regions.

This light field was used in our paper on plane+parallax calibration [8]. Since it was acquired outdoors, we were not able to perform color calibration.
