LensFix CI for OS X.4 and Photoshop CS3
LensFix CI is the next generation of our popular LensFix plug-in. LensFix CI is now a Universal binary (i.e. native on PowerPC and Intel Macs) Photoshop CS3 plug-in as well as a stand-alone application which can be used as an external editor in Adobe's Lightroom and Apple's Aperture. LensFix CI has many improvements including:
- Lightning fast corrections - uses your video card for processing when supported by your Mac (if your Mac supports Core Image on your video card, LensFix will do the corrections in near real time on your video card).
- Improved interface.
- Supports the PTLens database from epaperpress.com in addition to the current PTMac/LensFix databases. Well over 500 camera and lens combinations are supported. A copy of the PTLens database is included in the LensFix CI download. You can also enter and save your own settings.
- New perspective controls. You can easily change the viewing angle of the image.
- Full 16-bit support (plug-in version).
- Can read many common RAW formats (stand alone version).
- Works with Adobe's Lightroom and Apple's Aperture as an external editor (stand-alone version).

 Panorama Tools Photoshop plug-ins
Based on Helmut Dersch's Panorama Tools, our plug-ins for Photoshop can simply be described as versatile, accurate and powerful. Available for OS X only, our five plug-ins include the plug-ins Correct, Remap, Adjust and Perspective. The plug-ins can correct for lens distortions, extract flat images from panoramas, re-map images between many different image projections and much more.All the plug-ins are fully actionable in Photoshop and have a 15 day trial period. The LensFix CI (above) registration also unlocks the set of five plug-ins. The plug-ins can be downloaded from here and purchased here.
Here are some examples of what you can do with these plug-ins:
The Correct filter is the original Panotools interface for correcting image distortions. The functions of Correct have been incorporated in to the more user friendly LensFix.
The Remap plug-in converts between image projection types. The naming conventions have been continued from the original Panotools for backward compatibility. Specifically:
| Projection
|
Description
|
| Normal
|
Is the rectilinear format. This is the format of a normal lens.
|
| Cylndrical
|
Formerlly QTVR. Cylindrical images are created by many stitching programs and scanning cameras. |
| PSphere |
Also known as Equirectangular format. The type of image produced by flattening a sphere to a rectangle twice as wide as it is tall. Areas near the top and bottom of the image are stretched while the image near the middle of the image appear more normal. See the example below. |
| Fisheye Hor |
The type of image you would get by taking a photograph using a fisheye lens held horizontally. |
| Fisheye Vrt |
The type of image you would get by taking a photograph using a fisheye lens held vertically. |
| Convex Mirror |
What you would see when looking at a reflective ball. Some users have used this option to create panoramas of small places by taking photographs of mirror balls and re-mapping them into panoramas. |
Note: Some of the infrequently used panorama conversion options are available. For example, Convex Mirror to Fisheye Hor.
A popular use for Remap is converting full-frame fisheye images to the normal format. This allows users to use less expensive full frame fisheye lenses in place of more expensive ultra wide angle normal lenses. In the example below, we convert a 16mm full frame fisheye image to the normal format. Move your cursor over the image below to see the change. Note the tree on the left is straight. The tree in the background is actually curved as it leans over the water.
 In the example below, we take a 360º x 180º equirectangular (PSphere) panorama and remap it to the vertical fisheye option using the settings in the graphic directly above. The equirectangular panorama is rotated in Photoshop 180? prior to applying the filter so the ground is at the top of the image. By rotating the panorama 180? prior to applying the filter, the ground appears in the center of the remapped image. Otherwise, the remapped image would show the sky in the middle of the new image and the ground along the outside edge.
360º fisheye - the entire scene is visible in this unique perspective.
The Adjust filter was the original method for creating panoramas using Panotools. Now, the Adjust filter is most often used for extracting partial images from panoramas. By extracting images from stitched panoramas, you can offer your clients the option of using any part of the panorama in product literature. The example below shows an extracted image from the equirectangular panorama shown above. The image has a 112º horizontal field of view which is equivalent to a 12mm rectilinear lens on a 35mm camera. Chances are a 12mm rectilinear lens is not available for your camera. Note: Areas near the edges of the extracted image appear unusual because of the wide angle nature of the image. Images with a smaller field of view look more 'normal."
Adjust options used to create the above image.
Options for Insert/Extract are accessed by clicking on the "Set..." button on the Adjust Options box.
The Perspective plug-in offers users a way to change the orientation of an image as if the camera were positioned differently than it actually was when the photograph was taken. The example below shows how a fisheye image taken vertically would appear had the camera been oriented horizontally (90 degrees to the actual image).
