Bad sensor dust

wrote: 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. false. photoshop and several other tools, such as focus magic can help fix out of focus images: http://focusmagic.com I have my doubts, even after seeing the samples. doubt all you want. it works quite well in many cases. obviously not every case. nothing is perfect. It will be expensive, out of my bracket. it's not expensive and there are even free options available. Please tell those free options. https://www.gimp.org/tutorials/Smart_Sharpening/ http://refocus-it.sourceforge.net/ http://bigwww.epfl.ch/deconvolution/ http://www.deconvolve.net/DNLinks.html and price is not the issue anyway. you said it can't be done, and it can. I'll believe when I see it. I read bad critics about that software you posted, maybe even here. Information is lost with bad focus: to repair that, data has to be "created", thus false. but not necessarily wrong. |

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. The camera is a DSLR with an optical viewfinder and I#m guessing that the images were not inspected during the trip to Algeria, otherwise the photographer would have noticed the dust on the sensor. Given the camera, I suspect that the photographer is oblivious of the potential dust problem with all ILCs, DSLR, or MILC. It is probably his first DSLR. Actually, looking at the photos of previous trips (the Namibia one of last summer for instance) the dust on the sensor was already there, so it seems that the photographer doesn't even know that the problem exists, or simply doesn't care. or maybe likes that 'blobby' look ;-) If he is that oblivious to the potential dust problem, it is inexcusable, and he should stick to using a compact. At least one photographer made a great effort to breed and photograph dust. https://www.bing.com/images/search?view=detailV2&id=A4273D9E8C38302D1AFBBE723B 8096827DA1CB71&thid=OIP.KychV_yl4QThSwVkwDC2tAHaE0 &mediaurl=http%3A%2F%2Ffarm1.staticflickr.com%2F22 0%2F483604587_4352f1398c.jpg&exph=312&expw=479&q=m an+ray+dust+breeding&selectedindex=10&qpvt=man+ray +dust+breeding&ajaxhist=0&vt=0 -- PeterN |
