#Unity camera lens distortion manual#

If you desire further adjustments, move the Manual Correction slider to the left for a bulge effect, or to the right to stretch the edges of the image.

You can find this information displayed in the EXIF panel in the lower right corner of Develop mode.

From the Lens drop-down menu, select the lens used to take the image.

If the displayed camera make and model are not correct, select the correct options from the Make and Model drop-down menus.

In the Lens Correction group, select the Enable Lens Profile checkbox.

In Develop mode, select the Geometry tab.

To Fix Lens Distortion Using Your Lens Profile: You can save your settings as a preset for future use.įor quick viewing of the available lens profiles, go here. You can also use your lens profile to correct chromatic aberration, if it is available. You can use the Manual Correction slider for further adjustments after using automatic correction, or on its own. Mapping the lens profile will enable you to apply the correction to all images with the same camera-lens combination that you open in the Develop mode Lens Correction tool, should you choose. You can also map the correction specific to your lens, (the lens profile), to your camera make, model, and lens combination. If possible, recover the correct lens value and select it from the Lens drop-down menu. However, the lens value displayed in the EXIF may not be reliable in the case of third party lenses as the camera itself may only recognize the third party lens as an ID number. You can find the name of the lens used in the EXIF information of your image. The possible lenses for the selected camera will be available for you to choose from the Lens drop-down menu, unless there is only one possible lens, in which case, that lens will be pre-selected.

The Lens Correction tool contains a database of camera makes, models, and their possible lenses. Once a lens profile has been mapped to an EXIF profile, the Make and Model drop-down menus will be pre-populated with the camera used to take the image based on its EXIF information. The Lens Correction tool can apply automatic adjustments based on the distortion inherent to the lens used, or you can enable lens correction for each image manually. This can be done by selecting the make, model, and lens of the camera used to take your image. In ACDSee Pro, you have the option of using manual correction via the Manual Correction slider, or you can enable lens correction via your lens profile. Barrel and pincushion distortion are common in photos that were taken with wide angle or zoom lenses. In pincushion distortion the photo appears to shrink inwards toward the center. In barrel distortion the photo appears to bulge outwards from the center. The more proportional distance differene, the more stretching.You can correct barrel and pincushion distortion in digital photographs. The closer the sphere has to be, the more 'proportionally nearer' the 'near' parts of the sphere will be to the cam. The wider the FOV, the closer to the cam the sphere has to be to appear a certain size. $$anonymous$$ake your FOV narrower and move the sphere closer to center on the x-axis and farther from camera, and you'll get the 'same shot' with less stretching I'd say.

Note that Unity uses vertical FOV, so the wider your view is, the more stretching will happen at the edges of the screen. If it's perspective projection and has a wide FOV like in your screenshot, parts of the sphere that are closer to the camera will surely appear bigger and cause it to stretch. $$anonymous$$y knowledge of camera projection matrices isn't strong enough to argue strongly about this but I also can't imagine what kind of a perspective projection wouldn't have this problem. Are you sure $$anonymous$$aya's camera is a a perspective camera ( if you add a cube to the top corner of the view, can you see its bottom and side) ?
