Bad sensor dust
In article , Savageduck
wrote: recent slrs are much better, often with a dust shaker. The owners of cameras with sensor dust removal systems still need to make sure that it has been turned on. it normally defaults to on. However, there are some idiots who think they are extending the battery charge by turning off sensor dust removal. That is a false economy. technically they are extending it, however, it's nothing that would ever be noticed. taking a single photo will wipe out whatever savings, but as you say, they're idiots. |

My idea is to go there once and see how they do it. or do a search on how. there are plenty of detailed explanations and even videos. it's not difficult. even just one squeeze of a rocket blower would make a dramatic improvement. Maybe he takes the camera to a shop to be cleaned by a professional back home that knows how to do it, and he wouldn't dare try to do it himself, even less on a trip. or maybe he doesn't care. You do not know that. -- Cheers, Carlos. |

If he does not know how to go about cleaning the sensor on a DSLR, or MILC, he, and anybody who owns one should invest in the basic tools, correct size swabs, PEC pad, a Giottos Rocket, a bottle of Eclipse Fluid, and a magnifier with some sort of illuminator. I don't have any of that, nor my friends. I don't even know what they are. Then make the effort to learn how to go about cleaning a sensor, even on the road away from home. Especially if one is in an environment where dust contamination is likely. I had no idea about dust, and sensor cleaning until I got my first DSLR, a Nikon D70. I learned very quickly. Also, I believe the evidence that he is either oblivious to the problem, or just doesn't care is demonstrated by his posting of all those contaminated photographs to Flickr with no effort to fix anything. Well, maybe the photos themselves are important (to him) and he can not go back to repeat them. I have photos like that, with errors, but they are important to me. If they were important to him he should have taken care when producing them. He could certainly have cleaned up the spots on the images with post processing before publishing them in Flickr. I wouldn't know how. What camera do you shoot? If you have photos that are important to you, but have "errors", do whatever you can to fix those errors in post. That is why editing tools exist. You can not correct focus on post. -- Cheers, Carlos. |

I don't have any of that, nor my friends. I don't even know what they are. All it takes to find out what 'they are' is to search, and then buy. Amazon should lead you right to those items. Then you will have more knowledge than your friends. Then make the effort to learn how to go about cleaning a sensor, even on the road away from home. Especially if one is in an environment where dust contamination is likely. I had no idea about dust, and sensor cleaning until I got my first DSLR, a Nikon D70. I learned very quickly.

I wouldn't know how. Are you reluctant to learn anything? Cleaning up unwanted dust spots or other blemishes is a feature of most photo editing software, even some of the free software. What camera do you shoot? ....and which camera was it that you use? If you have photos that are important to you, but have "errors", do whatever you can to fix those errors in post. That is why editing tools exist. You can not correct focus on post. That is a whole different problem. -- Regards, Savageduck |
