And apparently the photographer wasan't even aware of the dust, as the blobs are on all or almost all images. Yup! The dust is very conspicuous, and is going to need some major fixing in post. That sensor is in dire need of cleaning, and the photographer should have taken an emergency cleaning kit with him on that trip. When you know that you are going to be in an environment with wind, dust, and sand, there is no excuse for not being prepared. At a minimum a lot of care should be taken with lens changes. That assumes he knows how to use that kit (I don't). 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. 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. 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. I'll wait till I can see someone doing it. 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. Are you reluctant to learn anything? Certainly not :-) Good! But I don't go criticizing somebody which posts some far from perfect photos, for reasons we don't know about. I only try to point out, as he is not here to defend himself, that there may be reasons. There is such a thing as constructive criticism, and he (and you)should consider this a learning moment in the journey as a photographer using an interchangeable lens camera (ILC). Maybe he did not intend you to see them, LOL! :-D That much is obvious. Maybe he doesn't know how to clean them, and there are no cleaning services in Algeria. ....or he is blissfully unaware of just how bad his images appear because of the dust. If you look at the end of his album, there is no dust: https://www.flickr.com/photos/marcodileo/6680221601/ If you go to page 20, I can see just one big speckle on the left on some photos. Maybe by that time he had found out how to clean the sensor or took the camera to some place. I doubt that he has learned anything. A closer look reveals dust spots all over his images. People take time to learn, after all. There is nothing to indicate that he is in anyway aware of the problem. All it would take is a little effort and republishing to Flickr. Me, I would not have posted with that defect without an explanation. Good. Cleaning up unwanted dust spots or other blemishes is a feature of most photo editing software, even some of the free software. Sure, but those are huge. Anyway, what that software does is some kind of interpolation, because the data of those pixels under the dust is lost forever. Different software does different things in different ways, quite a number use content aware algorithms to go about making clean-up edits with minimal damage to the underlying image. The cleaned up result will be much better than the spot contaminated original. What camera do you shoot? ...and which camera was it that you use? Oh, a Nikon D3200. What I could afford. I'm not a professional. There is nothing wrong with a D3200. It is an entry level DSLR, but everybody has to start somewhere. 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. It is. But it is the one I might want to correct, I don't have dust. You don't have dust spots YET. Sooner or later they will be there, and the photos will need fixing, and the sensor on your camera will need cleaning. -- Regards, Savageduck |

They say to bring the camera to the service shop. what cleaning kit did you buy that did not include instructions?? I bought a camera. excellent, except that the topic is cleaning kits. No, it is "bad sensor dust". I never bought or implied I had bought a cleaning kit. bad sensor dust is remedied with a cleaning kit, which you said you do not know how to use. cleaning kits come with instructions. read them and you'll know how. or watch a couple of videos. in some cases, no instructions are needed, such as a rocket blower. it's obvious how it works. or maybe he doesn't care. You do not know that. it's quite clear he doesn't care, else he wouldn't have posted a photo full of dust spots which looks like utter ****. Not to me. seriously? that photo was overwhelmed with dust spots. So? Maybe you were not the intended target. the intended target is irrelevant. the photo has a ****load of dust, as does his other photos. he clearly doesn't give a ****. |
