Scratched or damaged imaging sensor? We can replace the original Low Pass filter, with an OEM manufacturer provided filter, returning your camera back to perfect order.
The "Low Pass" filter has more than one purpose. First, it blocks
unwanted Ultraviolet (UV) and Infrared (IR) light from reaching the
imaging sensor, allowing the camera to render normal images of only what
the human eye can see. Secondly, the Low Pass filter protects the
imaging sensor from damage caused by foreign material contamination or
improper cleaning methods of the end user. If your imaging sensor filter
has been scratched or damaged you will notice imperfections on the
resulting images. Removing these imperfections during post processing
(using Photoshop, Aperture, etc...) can be very annoying especially when
editing large numbers of images.
