amit_bronstein Posted February 28, 2005 Share Posted February 28, 2005 hello I got a question from a colleague of mine. He was shooting with a p&S digital Casio Exilim EX-Z50, and got the attached result. I am almost sure that those are water spots but I am not positive because part od them looks too small, and from my experience with water spots om SLR's it doesn't look like that. Does anyone think it can be something else? I still did not see the camera. Sorry that it is not a canon issue (I myself using the 20D and familiar with this forum) Thanks, Amit<div></div> Link to comment Share on other sites More sharing options...
hkbmac Posted February 28, 2005 Share Posted February 28, 2005 That is flare from the bright lightsource on the side of the frame. Link to comment Share on other sites More sharing options...

charles c Posted February 28, 2005 Share Posted February 28, 2005 It's flare and water. Link to comment Share on other sites More sharing options...
amit_bronstein Posted February 28, 2005 Author Share Posted February 28, 2005 Can flare be so severe? is it that bad P&S lens quality ? Link to comment Share on other sites More sharing options...
phule Posted February 28, 2005 Share Posted February 28, 2005 It's not flare. I'm not sure if the umbrella was being used because of rain. If not then all of the spots are dust. If there was rain, then the spots are from rain. Fuji has an informative page devoted to dust and flash. Water dropplets behave the same way. These are not on the camera or on the lens but in the air. http://home.fujifilm.com/products/digital/tips/reflect/# Link to comment Share on other sites More sharing options...
wedding-photography-denver Posted March 1, 2005 Share Posted March 1, 2005 to me it seems to be a combination of a strong light source hitting the rain spots on the lens. IMO. Link to comment Share on other sites More sharing options...
vhic_cruz Posted March 1, 2005 Share Posted March 1, 2005 I've experienced this several times. This is cause by dust particles in the air in relation to flash. Notice they are all in circular pattern. If you have a flash gun with strobe mode, you can see the dust in the air. One thing to note is that in PS cameras, this is the same effect if there are dust on the cameras lens. Link to comment Share on other sites More sharing options...

david_french3 Posted March 1, 2005 Share Posted March 1, 2005 Many people believe these artifacts are spiritual orbs, representing ghostly activity. I am not making this up. Personally, I go with the dust-in-flash-light theory. Link to comment Share on other sites More sharing options...
amit_bronstein Posted March 1, 2005 Author Share Posted March 1, 2005 Thank you very much all for the great answers. I have a quesiton to VHIC. You claim that on a P&S camera it will be the same if it is on lens. Why is that? I guess becuase that the focus on P&S is almost inifnity but I think that a dust on the lens should create dark spot (to my opinion) and not white. Am I correct or I missed anything? Thanks, Amit Link to comment Share on other sites More sharing options...
amit_bronstein Posted March 1, 2005 Author Share Posted March 1, 2005 Mark. I think your link describes that in an excelent way. As I thought it will be much noticable in P&S camera's. Thnaks, Amit Link to comment Share on other sites More sharing options...
