What To Do If Dust Is On The Ccd Or On The Filter - Sinarcam Multipurpose Digital Camera User Manual

11. What to do if dust is on the CCD or on the filter

Even with perfectly cleaned CCD and color filters there are always tiny specks of dust in the air and
on the surface of the filters. As long as they remain tiny there is no need to something against them.
Blowing them away by a jet of air may just swirl the dust to some other region or let come some
additional dust laying on the surface of the CCD or of the color filters.To avoid any visible effects
from dust on the filters and on the CCD covering glass, try to do the following
• Do not stop down the lens if not necessary. Use the best f-stop range of each lens which is about 2
or 3 stops down from completly open.
• Do not use extremly steep toning curves in the leaf software
• Avoid changing belows and do not remove the DCB from the sinarcam body if not necessary
• Never leave the sinarcam body without a lens or the lens cover plate.
• When removing the DCB unit for some time always mount a protecting cover to the sinarcam.
If you find however spots in your image that are too disturbing, find out if the spots are on the CCD
(black spots) or on the color filters (yellow, cyan or magenta spots).
To clean the surface of the CCD follow these steps:
• Close the shutter of the sinarcam to protect the LCD-shutter and the color filters from dust. (If the
leaf software is running, stop the live video. If only the sinarcam software is running, press the " c"
key to close the blade).
• Remove the DCB-unit from the sinarcam body.
• Clean the surface of the CCD as described in the Leaf instruction manual.
• Check also the inside of the adapter plate and remove any dust if necessary.
• Mount carefully the DCB unit to the sinarcam body.
