Reading mode: Light Dark

Brand new DP2 giant red spot in middle of images!

Go to last post
Perhaps going outside might hide some or most of this anomaly and yes this was the first shot, but let me note, this is the first of at least ten shots. And if you look past the lamp it's kinda raining. That said you got to be kidding? this is a $650 camera not a Holga!

No disrespect (Really) I'm totally new here, but is this normal?
 
Not an expert on DP2 and not trying to explain away the odd image. But I'd echo Sandy's suggestion. I've occasionally found unexpected anomalies on images from light entering the lens I didn't notice - e.g. a transient reflection.

You might take a few photos outdoors or otherwise under very even, adequate illumination. Try a simple gray or otherwise continuous color test subject like a piece of card or fabric. Stay away from stray light sources. If you get similar results - suggest you contact your supplier. It's not a "normal" result of Sigma photography when shooting in normal conditions.

Best,

And I mean no disrespect either... but you have to work with any new camera a bit to begin to understand it... You've got a mixed lighting situation.... I assume the lamp was lit so you have bright light within the shade, and it's brighter than the surrounding light, different color temperature; no flash, so it's a backlit situation where you underexposed the lamp and table and general scene.

True, mixed lighting can produce occasional weird effects.. you'll read about such if you follow this forum. I wrote out a lot of general ideas on using DPx and Sigma Photo Pro in another thread, this is a link to one of my first posts on the thread. You might want to read through it. http://forums.dpreview.com/forums/read.asp?forum=1027&message=32127795

Granted a lot of people get their new camera in afternoon and evening... and take shots of their living room, their TV set, cat/dog, whatever. My new Pentax K20D in January I photographed the TV set in the family room and had wavy lines on the TV screen, hmmm, but I didn't post in the Pentax forum that I was disappointed in the camera...LOL.. I started to figure it out instead...

Well your a Pentaxian! awesome so am I! (K20 as well) bought this little guy for a pocketable alternative to my K20. By the way the lamp wasn't lit.

Really? now that IS strange...I thought I had it figured out, LOL ... no light source than the window behind? no flash? hmmm...

My 'main' camera is the Sigma SD14 as I mainly do landscapes, nature shots, florals, natural light, and I love the fine detail capture of the Sigma/Foveon cameras.. that's my 'thing' .. fine detail capture. I don't have a DP2 (yet) but I've shot the DP1 since it came out in March 2008.. and the general nature of the DP2 and DP1 are rather similar .. and also related to the SD14. I've had a Pentax DSLR since 2006, bought a K20D in January and gave the K200D to daughter recently... But I use the K20D in rather specialized settings... indoors, museum shots in Washington, DC, performances in low light, museums/theatre stages for dancers programs for example. I prefer the SD14 for nature work .. .which is most of my photography. The DP1 fine detail capture in good light equals or exceeds the K20D in my opinion... and the DP2 lens is as good as the DP1's if not better perhaps. I'm also a low ISO fanatic... I won't shoot over ISO400 if I can possibly avoid it... any camera... I won't compare the DP2 to K20D as I don't use the DP2 yet...

...it could be a bum sensor or just an aberration. I too thought the lamp might have been on, but no. FWIW my DP2 has been all but problem free. If you can and need to exchange it, do so for peace of mind.

Good luck,

Hello! new here and just got my new DP2 charged the battery and this
what I got :(

any ideas?...very disappointed I was very excited about using the
foveon sensor for the first time now...not so much.

One other note this anomaly was in the shot as I was framing it.

It looks really messy. Now you can get nasty effects from bright light sources with the Foveon, I sometimes see that in the DP1 too. Never like the one you posted though, i.e. the bright spot should be in the picture somewhere...
Were you able to reproduce this?

The light might make some sense as noted if you had a strong light
source causing the lens to flare... but that doesn't really look like
any flare I've seen, and you say it's in other shots.

If you can, I'd return that for a new one - or send to Sigma for
replacement. Sorry to hear you got a bad one.

Given the additional information since the original post, I tend to agree. If it's reproducible in varied lighting/subject, something seems amiss. Barring a smear or other impediment on the exterior lens surface, I'd contact Sigma. Why you would get an arguably defective unit? Don't know. QC? Damage in shipping or handling? Reminds me of the images from the ill fated video camera on one of the Apollo lunar missions - back in the days of tube type imagers - when the camera was inadvertantly pointed at the sun and burned the target of the imaging tube. Not as likely I suspect with today's solid state sensors although possible I suppose.

Edit - just thinking about my comment about sensor damage - since the DPs have live view, do they have a physical shutter? If not, pointing the camera (inadvertantly or otherwise) at an extremely bright light source and/or for a protracted time (e.g., setting it turned on, on a sales counter pointed outdoors at a bright sun reflection (of indeterminate shape) "might" cause damage????

have you taken more photos in "normal" light conditions, say natural light or mixed light room(s)? Has anything similar appeared?

I've looked at your one DP2 photo online quite a few times and still cannot figure it out.. what was the light source? was there an overhead light? or light source somewhere that might have been flaring somehow? There is evidence of some pink flare around the red splotch... I have a DP2 I bought from Amazon arriving Friday and I'd love to try to reproduce the effect, just for curiosity if possible; would you describe the lighting around the shot?

Am quite sure the answer is this. I notice that its raining (drops on window) and am sure a vehicle has just applied its brake lights just as you fired the shutter.

I'm making assumptions that this is not on every image. If so...I think it could be those infernal internal reflections at the back of the lens again, the ones that blight some 'into the light' shots. Admittedly its a different 'pattern', but the colours right!

What are the other images like?

Maybe this camera just doesn't like certain lighting situations, but in the other conditions its perfectly fine. Certainly a camera to learn to live with its limitations.
