Anguish Posted February 7, 2010 Share #1 Posted February 7, 2010 Advertisement (gone after registration) Check out the purple electro-static-looking clinging smear drips in the lower right snow shadow. 40 mm Summicron w/ IR/UV filter. Artifact caused by: 1) High-altitude electro-static cold-wave clinging-smear phenom 2) Lens flare augmented by condensate residue on front filter UR/IV element 3) Secret Service still jamming in the neighborhood of the undisclosed location 4) Cat pissed on the sensor 5) Your explanation Link to post Share on other sites More sharing options...
Advertisement Posted February 7, 2010 Posted February 7, 2010 Hi Anguish, Take a look here atifact of the century. I'm sure you'll find what you were looking for!
ho_co Posted February 7, 2010 Share #2 Posted February 7, 2010 Ang, I feel your pain! That's weird, indeed! At least it looks like a fun trip! What RAW converter are you using? Some earlier versions of Photoshop did similar things, but I saw them mainly in grossly overexposed areas. Maybe try a different RAW converter? But you may be right that this is a new grungeblob undergoing weaponization. Link to post Share on other sites More sharing options...
ArtZ Posted February 7, 2010 Share #3 Posted February 7, 2010 I think the main reason is the UV/IR filter used in contre-jour light plus chromatic aberration of the lens. I got three similar pictures like yours in Costa Rica on a sunset with a Summilux 35 asph and two with a Summicron 28 asph. The ones taken with the Summicron 28 were better than the ones with the Summilux 35. Personally,contre-jour photography with IR/UV filters on is like winning the lottery Link to post Share on other sites More sharing options...
SJP Posted February 7, 2010 Share #4 Posted February 7, 2010 Overexposure by about 5 stops? Link to post Share on other sites More sharing options...
luigi bertolotti Posted February 7, 2010 Share #5 Posted February 7, 2010 I join ArtZ opinion... UVIR filter in such EXTREME contre jour inevitably brings something strange... I patiently made hand corrections in PS to fix them in alpine skiing pictures... Your image is stunning anyway. Link to post Share on other sites More sharing options...
pgk Posted February 7, 2010 Share #6 Posted February 7, 2010 Look on the bright side - at least you haven't ended up with yet another technically perfect and boring shot. I actually rather like it because for once it illustrates the severe brilliance of the light and is different. I shoot against the light a lot and whilst the UVIR effect is sometimes problematic, its never boring. Link to post Share on other sites More sharing options...
Anguish Posted February 7, 2010 Author Share #7 Posted February 7, 2010 Advertisement (gone after registration) Thanks all. This attempted picture was very much a hit-and-miss proposition that gambled on a powder cloud or the skier obscuring part of the sun and its effects. Because of my positioning, I didn't get the obscuration I sought, and thus came the corresponding and anticipated lens flare, overexposure and novel purple-static-cling artifact. Resolutions: M9 w/o IR filter Try again to obscure the sun Stop down Copyright the purple-static-cling pattern for use as camo for an invasion in the mauve environment.

Anguish, Just for curiosity, which lens were you using? I'm asking you this because few months ago we had a thread about IR filter reflections and 35 mm lenses (Leica, Zeiss and CV) seemed to prone reflexions more than other focal lenghts.

Angelos Viskadourakis Posted February 7, 2010 Share #10 Posted February 7, 2010 1/great effect in an otherwise ordinary shot. 2/shooting in the sun with 40mm on a CCD creates blooming. 3/the amount of energy-light-trapped for that section of time in a small narrow tunnel full of glasses-the lens-with focus closer than the infinity create havoc in the optical path. 4/dust and frozen humidity in the lens analyze the spectrum as they create surfaces in the light path. 5/shooting with a similar focal length with any medium -including film-in the high sun at this time of the day would create optical effects that will vary according to focus distance,lens quality and age,angle in relation to the sun. 6/any filter of any maker and any type will do some kind of similar effect. 7/an APO lens maybe,again maybe will create less effect. 8/i have shot in film with 15mm Leica R against high sun ,focus in infinity and the sock was less for lens and medium. 9/diffraction in a rather very close iris contributes. wide0919 copy on Flickr - Photo Sharing! http://bighugelabs.com/onblack.php?id=3241663905&size=large Link to post Share on other sites More sharing options...
