TonyField Posted December 28, 2013 Share #1 Posted December 28, 2013 Advertisement (gone after registration) I have never seen this type of flare ever before. I suspect is is an odd property of the 75mm Elmarit -- however might also be a strange interaction between the sensor surface and the lens. On the other hand, this might be proof that our sun is truly a binary star Welcome, dear visitor!

Gerard Posted December 28, 2013 Share #2 Posted December 28, 2013 I could be wrong, but I think it is sensor bloom. The sensor not coping with the angle and intensity of light hitting it. Link to post Share on other sites More sharing options...
TonyField Posted December 28, 2013 Author Share #3 Posted December 28, 2013 I can easily accept blooming as the "diffused halo" surrounding the two sun images. However, it does not make sense that two distinct images of the sun are clearly imaged can be explained by "blooming". Link to post Share on other sites More sharing options...

TonyField Posted December 28, 2013 Author Share #5 Posted December 28, 2013 Trick question?Steve Not at all. The image is essentially out of the m9 with 75mm elmarit taken at 1/4000 sec, F11. I cannot explain the clear double "images" of the sun that seem to surround the actual sun in the centre of the diffuse flare. Link to post Share on other sites More sharing options...
luigi bertolotti Posted December 28, 2013 Share #6 Posted December 28, 2013 I could be wrong, but I think it is sensor bloom. The sensor not coping with the angle and intensity of light hitting it. I tend to agree... is a strip a lot symmetrical... not related to the whole image of the sun's circle in itself... central pixels, roughly spekaing, have "burned" the adiacent ones, with the in camera processing making the rest (something to do with the almost perfect arcs at the sides of the "burned strip") Great image, by the way... worths a careful correction wihich can surely be made with patience.

Jean-Michel Posted December 28, 2013 Share #7 Posted December 28, 2013 Advertisement (gone after registration) I think that this is a typical issue with the M9. I have a number of similar images with the blown out strip usually vertical rather than horizontal. Nothing to do with the lenses.

wattsy Posted December 28, 2013 Share #8 Posted December 28, 2013 Agree with the consensus – whether it is called "blooming" or not it is definitely a sensor effect and nothing to do with lens flare. A slightly more extreme example below, including a 100% crop (photo taken with Monochrom and 35 Summilux). Welcome, dear visitor!

luigi bertolotti Posted December 28, 2013 Share #9 Posted December 28, 2013 Btw, makes me remember the old "green line" issue which me too experienced on M8, with strong lghts next to the sensor's border - lens indipendent, of course. Link to post Share on other sites More sharing options...
TonyField Posted December 29, 2013 Author Share #10 Posted December 29, 2013 Thanks Ian for the sample photograph that replicates my issue. At least I know I am not alone with the issue. It would be interesting to find out exactly what causes this type of flare. Link to post Share on other sites More sharing options...

Jean-Michel Horizontal in vertical pictures, vertical in horizontal pictures. Same as with dread green streak with the M8 Apparently the read out or in (?) goes vertcal in the two halves the M8/9 pictures are composed of.

farnz Posted December 30, 2013 Share #12 Posted December 30, 2013 … It would be interesting to find out exactly what causes this type of flare. Oversaturation of the sensor's photodiodes through chronic overexposure of a point or focussed light source I should think. Pete. Link to post Share on other sites More sharing options...
luigi bertolotti Posted December 30, 2013 Share #13 Posted December 30, 2013 Oversaturation of the sensors photodiodes through chronic overexposure of a point or focussed light source I should think. Pete. My opinion too... "crazy tons of photons" that no sensor or firmware can manage... Link to post Share on other sites More sharing options...
jankap Posted January 1, 2014 Share #14 Posted January 1, 2014 OK, a very over saturated sun in the center and two parhelions. Why only in one direction? And with such sharp edges, see 100% crop picture? It is a situation outside the specifications, of course. Meaning, one can expect everything. It is a very nice picture, by the way.
