Leaf Aptus-II Calibration Manual

6 Notes:  In the example above Leaf Capture has limited the lens falloff correction to 60%. You can reduce this number as desired.  The falloff correction is applied for this load only. The name and path of the Lens Calibration and the % Falloff correction used, will appear in the Image Info of images shot with the Lens Calibration. ...

3 Lens Calibration Guide Introduction Shooting images with wide angle lenses and exploiting large format camera movements often results in lens fall-off and color cast effects. Another effect is the so-called centerfold effect where lines may appear in the image. Lens Calibration corrects all three of these effects. The following shots show the same image with and without lens calibration: What is lens cast and how is it recognized? Why is Lens falloff associated with lens cast? Lens cast results when light from the lens strikes the digital sensor at shallow angles causi ...

12 Brightness compensation Using Lens Falloff correction tends to create images that seem brighter. You can adjust brightness or the develop curve to compensate for this or shoot the images at a lower exposure level. Creating the calibration shot in low light In some conditions, you may not be able to create an optimally exposed calibration file as described above because the required exposure time is greater than the maximum. This could happen when you are shooting using indoor lighting, under a low sun, and so on. In these casestake the calibration shot at the maximum ...

9 Applying a Lens Calibration After shooting youcan applya Lens Calibration to images that were shot without one. You can do this in both Leaf Capture and in Capture One. After shoot – Leaf Capture 1. In Leaf Capture, select the images you would like to process. 2. In the Process panel, select Leaf Mosin the Format list. 3. Click Settings. 4. The Leaf Mos Settings dialog box opens. 5. To save the mos file with lossless compression, checkSave Compressed. 6. CheckLens Calibration Adjustment. 7. Select Select Calibration File and click the browse icon. 8. Select the lens ...
