Sigma SD10 sample clip JPEG + MORE
There's so much rubbish circulating here both for and against Sigma SD10
and Foveon that I thought I would place a small clip from an image where it can be viewed. Be aware - I'm using this camera professionally, for stock shots. The image is a highly soft-focus, totally non-sharpened, creative colour shot as an overall pic. And no, I'm not posting the whole pic. It is a small clip from a 3350 x 5025 pixel (larger than 48 megabyte) 16-megapixel resizing from a Sigma SD10 image. Absolutely no reprocessing has been done, in fact the import is using Photoshop CS with detail, luminance noise and colour noise ALL set to zero. It is a straight image, taken with an adaptor-mounted 105mm Super Takumar (1965) at full f2.8 aperture to give me the exact 'glow' which I want. There is a core of sharp detail - bear in mind this is a Sigma image enlarged over 2X from its native resolution - and the smooth quality of the colours and tones, along with the high luminosity and vivid palette, are precisely what I'm looking for in this context (an on-line picture library). URL: http://www.freelancephotographer.co.uk/poppyclip.jpg The JPEG setting here is quality 8, though normally these files are submitted on CD-R as TIFF images, and that is what the full size shot remains. I do not use the Sigma camera for all shots, but I am able to judge its strengths and make use of the unique feel the Foveon image has. Others do not seem to be able to look beyond whatever system they happen to feel loyalty to - personally, I'll use anything and everything in search of the right final image. You may like to visit: http://www.alamy.com/ And then do a SEARCH using - Icon Digital Featurepix and also David and Shirley Kilpatrick These two copyright names will bring up two sets of images, totalling over 300, with a variety of subjects. It is easy to tell the earliest ones shot on 5 megapixel cameras as they are only small files. Later ones, whether on Nikon D100, Sigma SD10, Minolta 7Hi, Minolta A2, Fuji S2 Pro, Olympus E-1 or Kodak DCS Pro SLR/n are generally larger available file sizes. Examine all these files if you like, and try to identify which of them have the faulty colour (or any other problems) which get ascribed to Sigma SD10. Try to tell which are from ANY particular camera - or even the few (about half a dozen) which are scans from film. They are just snaps - I'm really just a snapshot photographer, don't expect any models or studio sets or incredible locations, I just shoot pix on holiday like anyone else, or round the house. But I do manage to sell a few. David |

It's nice to see one of the locals doing okay, for one thing :-). And to get to see a wide sample of your professional work. And to find another useful stock site; I've had occasional needs to buy stock for web design, and more sources are good. -- David Dyer-Bennet, , http://www.dd-b.net/dd-b/ RKBA: http://noguns-nomoney.com/ http://www.dd-b.net/carry/ Pics: http://dd-b.lighthunters.net/ http://www.dd-b.net/dd-b/SnapshotAlbum/ Dragaera/Steven Brust: http://dragaera.info/ |

I am assuming, based on viewing this shot, that you were intending this image to show it's failings. If this was somehow your desired effect, then I apologize...but it looks like a big mess to me. You mention intending a "glow." There's a glow, alright, but it seems to be the "glow" of optical or sensor failures rather than an intended technique. |

(It's total ****e. What was the point again, indeed?) |

Almost none I would say - which is refreshing and unusual. - personally, I'll use anything and everything in earch of the right final image. Yeah! I have used pinhole cameras, carbon printing, etc, etc .. I have used rasters, lith developers, solarisation, ... But I have also use large format cameras, and I love the resolution and smoothness you get. Unfortunately, digital cameras with the same kind of quality is far outside my reach though. /Roland |

It is a fuzzy picture that can be made from a Bayer or a Foveon. The colors are wrong, but that can be made in Photoshop. The old lens might be the reason for the fuzziness, or is it the upscaling algorithm. Both Bayer and Foveon take sharper pictures than this. /Roland |

This is why I asked the question as to what it suggests to him. I fail to see any point to it. It looks bad on numberous levels... -Color rentition (I don't know of any neon-colored flowers) -CA problems -General fuzziness that is beyond the simple limitations of resolution. So... What was the point of it? I don't know. |

i didn't understand what that image was trying to tell me... but looking at
your site i found your article on the camera with a very interesting conclusion... perhaps others will also enjoy reading it if they haven't seen it already... http://www.freelancephotographer.co.uk/sigmaSD10.pdf "David Kilpatrick" wrote in message ...

It is all backed up in a very trustworhty way with lots of analyzed photos as illustration. Very nice article - but is it true? Is this the article that will get the world to "See the light"? Somehow it looks like a Sigma ad. /Roland |
