ronhartman Posted December 6, 2008 Share Posted December 6, 2008 <p>Hot pixels?<br> Do they show up in the same place if you take a picture of a plain white wall and underexpose by a few stops?</p> Link to comment Share on other sites More sharing options...
chinmaya Posted December 6, 2008 Author Share Posted December 6, 2008 <p>I have got this only one time. As attached in previous post. I just tried 'picaturing plain white wall and underexposing' ... no I don't get them..</p> Link to comment Share on other sites More sharing options...
William Kahn Posted December 6, 2008 Share Posted December 6, 2008 <p>Could they be actual light sources from structures in the hills? Sometimes you don't notice those kinds of details when you're concentrating on getting the shot right. </p> Link to comment Share on other sites More sharing options...
michaeljlawson Posted December 6, 2008 Share Posted December 6, 2008 <p>I though the same thing as William. A reflection from a metal roof or something of that nature.</p> Link to comment Share on other sites More sharing options...
sarah_fox Posted December 6, 2008 Share Posted December 6, 2008 <p>Yeah, reflections you didn't notice. The best solution is to clone them out in postprocessing.</p> Link to comment Share on other sites More sharing options...
keith reeder Posted December 6, 2008 Share Posted December 6, 2008 <p>Yep, reflection, not dead/hot pixels.</p> Link to comment Share on other sites More sharing options...
g dan mitchell Posted December 6, 2008 Share Posted December 6, 2008 <p>They look like reflections to me, too - not like "hot pixels," etc. Because they are so much brighter - probably reflecting direct sunlight - they are blown out making them pure white.</p> Link to comment Share on other sites More sharing options...
dillan k Posted December 6, 2008 Share Posted December 6, 2008 It looks like it could be a road, or maybe some buildings. Link to comment Share on other sites More sharing options...
davebell Posted December 6, 2008 Share Posted December 6, 2008 Apply a little logic, its not difficult. Do they appear on all your pics, yes/no. etc... draw some conclusions. Link to comment Share on other sites More sharing options...
sbp Posted December 6, 2008 Share Posted December 6, 2008 <p> It appears to be getting dark. These could be house lights, car headlights, or any other light source. </p> Link to comment Share on other sites More sharing options...
michael.gregory Posted December 6, 2008 Share Posted December 6, 2008 <p>1. They appear to be elongated.<br> 2. They appear to be following the kind of track that one would expect to see in a road switchback.<br> I'm betting car headlights</p> Link to comment Share on other sites More sharing options...

derek_kennedy Posted December 7, 2008 Share Posted December 7, 2008 <p>Without seeing the larger original image, I would have to agree that those white spots appear to be reflections off of iether roofs or wet roads. A hot pixel would normally be just one (or a few) pixel - not such a large group such as in your image.</p> Link to comment Share on other sites More sharing options...
