I know you take your competition entries seriously, but you just seem
to ignore basic maintenance such as cleaning sensor dust. That is something you really need to take care of as there is only so much you can fix in post. If you don't see the dust spots, particularly in color fields such as sky, that doesn't mean that other folks can't see them. Since you are happy using ACR, select the *Spot Removal* tool and check the *Visualize Spots* check box, and bump the zoom up to 100%. https://dl.dropbox.com/u/1295663/FileChute/screenshot_897.jpg If you inspect the sensor, those dust spots should be in the bottom right corner, but I suspect your contamination is spread further than that. I have to ask, after all this time and experience you have with DSLRs, do you ever clean your camera's sensor? ....or should I say, have you ever cleaned any DSLR sensor? If not you really need to learn how to do it. Either that or pay for regular cleaning by whoever works on your cameras. If they charge you for sensor cleaning, trust, but verify. Shoot wide open at a good monochrome color field target and check that the spots are gone. If you want information on cleaning tools just ask. -- Regards, Savageduck |

I must admit that in all my time with DSLRs I have only ever needed to clean the sensor once or twice, and that was achieved simply with a small blower removing a speck of dust from the surface on the sensor, using a very gentle puff. Since sensor-shale auto-clean was introduced by Nikon, was that the D60?, I have never needed to clean the sensor. I have yet to gain enough experience with the micro-four-thirds camera, but I expect the same to apply. Obvously I don't shoot in such dusty environments as Peter, and perhaps using the 10:1 zoom as my normal lens I need to change lenses rather less often (although a wide-angle lens is sometimes on both the DSLR and the CSC cameras). -- Cheers, David Web: http://www.satsignal.eu |

However, the shape and persistence of the dust spots after using the blower will mean wet cleaning is unavoidable. When I clean a sensor, it's usually a three-step cleaining process: 1. Rocket blower. If that doesn't get it clean, go to #2 2. Nylon brush. A blast of compressed air on the brush gives it a static charge and it will lift most dust off of the sensor, If that doesn't work, go to #3 3. Wet cleaning.

I have a bad habit of not cleaning my sensor. In fact the last time my sensor was cleaned was a few years ago, on my D300, and PAS did it for me. It isn't just a matter of not cleaning the sensor, it is a matter of being aware that the sensor needs cleaning. Checking for dust spots in non-textured color field such as blue sky should be part of your workflow. They can be removed in ACR, LR , or with the other PS tools, but with good maintenance that is not always necessary. You need to learn how to do it yourself. With the D800 and with sensor cleaning turned on at power up you shouldn't be seeing the dust that is there. If you do that then, unless you are in the habit of changing lenses in high wind without protecting the change, you shouldn't have to deal with serious dust and wet cleaning much more than once or twice a year. The other precaution to take, is to wipe down the camera and lens (particularly the lens/camera interface) with a soft cloth or PEC Pad when you get home after an outdoor shoot. Using a brush or blower around the lens/camera interface is the best way to handle that. I recall saying something about dust in your D800 images some time ago. It is something you need to get done ASAP. -- Regards, Savageduck |
