Not For Resale – Free Download at http://www.joe-chan.com/manualsWhen using negative film, however, natural light fall-off present in traditional optical printing set-ups (mostfilm labs and mini-labs) automatically compensatesfor this to a greater extent in the print. Therefore, whenusing negative film and with the lens stopped down,there may be no need to use a centre filter.29The only way to eliminate light fall-off at the corners isto reduce the amount of exposure at the centre of theimage. The Centre filter XPan works by a concentra-tion of neutral density at the centre and a progressivereduction of density towards the outer edge. The effectat the centre of the filter corresponds to a 1 f-stop re-duction in exposure.The filter is multi-coated to ensure high anti-reflectionquality. No degradation in MTF is seen and there is noshift in focus.The filter performance is optimised to give even illu-mination at larger or medium sized apertures.Tips & Reminders Photographers normally used to working with SLRcameras should particularly check that the lens cap hasbeen removed when making exposures. Flashing shut-ter speed and flashing low exposure symbol warningappear in the viewfinder. Take care if using other types of lens shade or filter hold-ers. As the XPan II does not have a TTL viewing systemit will be difficult to judge effects and possible vignetting.They may also obscure the rangefinder optics and causevisual focusing difficulties through the viewfinder. Regularly check that the controls are set correctly be-fore you take a photograph. For example, you may haveset the camera at ASA/ISO override for a previous filmand have forgotten to reset the Auto DX code setting.Or perhaps you have forgotten to reset an exposurecompensation. When using the panorama format, ensure that you com-pose accurately, or at least allow a margin for error. Ifyou decide to crop an image later, to level a horizon forinstance, you may be forced to mask off slightly morethan normal compared to a similar correction in thestandard format, owing to the panorama format's greaterlength.
