daniel_heiner Posted September 6, 2015 Share Posted September 6, 2015 <p>Hello everyone! I took a picture with my Nikon Coolpix S8200 and the images came out with circles in them :/ Does anyone know what the problem might be? Thanks a lot in advance.<img src="https://40.media.tumblr.com/8f6704000137e95205c42cbca0cdda91/tumblr_nu9wmli1ep1r1nm1bo1_540.jpg" alt="" width="540" height="405" /></p><div></div> Link to comment Share on other sites More sharing options...
User_6502147 Posted September 6, 2015 Share Posted September 6, 2015 <p>When you compress jpg....it can "pasteurize" on you. If the original image is RAW...I usually try not to reduce it till somewhere around 1-2 MB, because any subsequent reductions tend to amplify this effect. There might be other approaches, but this normally works for me.</p> Link to comment Share on other sites More sharing options...
daniel_heiner Posted September 6, 2015 Author Share Posted September 6, 2015 <p>Hi Leszek! Do you think there's something wrong with the lens? Because I zoomed in whilst taking the picture and horizontal lines began to show... </p> Link to comment Share on other sites More sharing options...
johnkenthill Posted September 6, 2015 Share Posted September 6, 2015 <p>If you were in the process of zooming while you took the picture, that might account for it. Is it like this on all pictures or just this one?</p> Link to comment Share on other sites More sharing options...
daniel_heiner Posted September 6, 2015 Author Share Posted September 6, 2015 <p>Hello John! It's like that on all the pictures... What can I do? :/</p> Link to comment Share on other sites More sharing options...
johnkenthill Posted September 6, 2015 Share Posted September 6, 2015 <p>You might try resetting the camera. Go to MENU > Setup > Reset All<br /><br />That's about the only suggestion I can think of for the moment. Perhaps that will correct any kind of setting that might cause the problem. I'll be curious to know if that makes a difference.</p> Link to comment Share on other sites More sharing options...

craig_shearman1 Posted September 6, 2015 Share Posted September 6, 2015 <p>This has nothing to do with your lens or zooming.<br /><br />What I'm seeing is a moire pattern -- concentric circles similar to those on a fresnel lens. This is what you used to see if someone wore a seersucker suit or jacket with tiny checks on televison. The pattern would "beat" against the TV lines and come up with a similar effect. Not sure what's causing it here since I don't see fine lines or check in the subject matter</p> Link to comment Share on other sites More sharing options...
daniel_heiner Posted September 6, 2015 Author Share Posted September 6, 2015 <p>I forgot to mention that the colour is off as well. The crystal next to the candle is supposed to be purple but appears another tone in the photograph</p> Link to comment Share on other sites More sharing options...
Spearhead Posted September 6, 2015 Share Posted September 6, 2015 <blockquote> <p>If the original image is RAW</p> </blockquote> <p> <br> It can't be with that camera. That probably explains this:<br> </p> <blockquote> <p>I forgot to mention that the colour is off as well.</p> </blockquote> <p> <br> Probably a white balance mismatch causing the color issues. Because it can't be shot in raw, WB problems aren't going to fully correct.</p> Music and Portraits Blog: Life in Portugal Link to comment Share on other sites More sharing options...
William Michael Posted September 6, 2015 Share Posted September 6, 2015 <p>I am seeing Moiré Patterning, also.<br /> Viewing the larger image (in the link) at various enlargements makes the Moiré Patterning more obvious:</p> <p><img src="http://d6d2h4gfvy8t8.cloudfront.net/18081875-md.jpg" alt="" width="680" height="485" /></p> <p>***</p> <p>One possibility is that there was something located in-between the Lens and the Subject, for one example - a fine mesh. <strong>Was there?</strong><strong> <br /></strong><br> Or was it a Photograph of an image on a screen?<br> <strong> </strong></p> <p>WW</p> Link to comment Share on other sites More sharing options...
dave_s Posted September 6, 2015 Share Posted September 6, 2015 Could the circles be Newton's rings? Is there a flat filter or glass or something which has separated from the sensor? Link to comment Share on other sites More sharing options...
daniel_heiner Posted September 6, 2015 Author Share Posted September 6, 2015 <p>William: No, there was no filter or screen... it was simply a picture of a candle and a crystal... </p><div></div> Link to comment Share on other sites More sharing options...

William Michael Posted September 6, 2015 Share Posted September 6, 2015 <p>I also was thinking about the inside of the camera, but -</p> <p>Newton's Rings are usually not symmetrical (this pattern is symmetrical) and more likely than not, Newton's Rings have a tint of colour to them, often pink (this pattern does not).</p> <p>I am NOT stating - <em>"these are not Newton's Rings"</em>, but, the pattern doesn't conform to the pattern of any Newton's Rings, which I have experienced.</p> <p>WW</p> Link to comment Share on other sites More sharing options...
daniel_heiner Posted September 6, 2015 Author Share Posted September 6, 2015 <p>Did you check the other example? </p> Link to comment Share on other sites More sharing options...
William Michael Posted September 6, 2015 Share Posted September 6, 2015 <p>Daniel: Thank you for the quick response to my first question.<br> <br /> If that first image does present with Moiré Patterning, then, at this time, I am clueless as to the possible cause(s) of that Moiré Patterning.</p> <blockquote> <p>I attached another example . . . Did you check the other example?</p> </blockquote> <p>The second example (posted Sep 06, 2015; 11:07 p.m.), shows a different pattern.</p> <p>That pattern appears to be like images reported to have interference from electricity or radio frequency. That, I think, is unusual, but there have been reports. So, the next question: for the second sample - were you near (big) Electrical Devices or Radio Frequency Transmitters?</p> <p>If these patterns (all be they different patterns) are happening for each and every shot you make with the camera, then it seems to me that there is something faulty with the camera.</p> <p>WW</p> Link to comment Share on other sites More sharing options...
AlanKlein Posted September 7, 2015 Share Posted September 7, 2015 <p>The first picture has different circles when you compare the one posted and its attachment. Maybe Vogt in his post is right about pasteurization although I don't know anything about this. Maybe he can explain?</p> Flickr gallery: https://www.flickr.com/photos/alanklein2000/albums Link to comment Share on other sites More sharing options...
mendel_leisk Posted September 7, 2015 Share Posted September 7, 2015 <p>I took one shot with my new DSLR, in Toronto's city hall plaza. Later noticed these super fine diagonal lines: very concerned there was some sorta defect in the sensor. Was back there a year or two later, saw there were fine wires crossing the plaza, lol.</p> <p>Anyway, your moire-like pattern, if it's only on that one shot, is likely something physical going on. Shot through a window?</p> <p>Editorial: Leszek, it's "posterize", not "pasteurize".</p> Link to comment Share on other sites More sharing options...
qalam Posted September 8, 2015 Share Posted September 8, 2015 If your camera is still under waranty return it for servicing. If the waranty has expired, get an estimate for repairs. The S8200 is highly rated in its category. If all pictures have this problem and there is no filter or other object between the camera and the subject, the camera is broken.

bobatkins Posted September 12, 2015 Share Posted September 12, 2015 <p>The large image is odd. It has almost vertical parallel almost straight lines throughout the image with small yellow dots on them.</p> <p>Some/most of the patterning in the downsized images is almost certainly due to aliasing. I'd be far more concerned about the parallel lines the the large image then the aliasing effects which results from them. They look almost like scan lines of some sort, but that would be hard to explain. The lines aren't quite parallel either. Looks like a picture shot through a fine grid with yellow dots on it, using a lens with mild pincushion distortion.</p> <p>I'd suspect a camera problem in the sensor readout or processing electronics/firmware, but it's hard to get lines like that from an orthogonal pixel grid, especially the slight curvature. The curvature sort of implies an optical effect</p><div></div> Link to comment Share on other sites More sharing options...
bobatkins Posted September 12, 2015 Share Posted September 12, 2015 <p>This is what the lines look like at 800% and in the center of the image.</p> <p>I suppose they could be due interference fringes from lens element separation or an air gap in the sensor structure, but they are rather high in contrast and rather finely spaced and regular for that and that doesn't explain the yellow dots!<div></div> Link to comment Share on other sites More sharing options...
dave_s Posted September 14, 2015 Share Posted September 14, 2015 <p>FWIW, I agree my suggestion of Newton's rings was probably wrong, and it's probably something electronic.</p> <p>The lines are too discrete for Newton's rings. I think the density of Newton's rings should probably be sinusoidal, but it's a long time since I thought about physics.</p> Link to comment Share on other sites More sharing options...
