Sigma SD10 Web Site Update
The Sigma SD10 Information Site has been updated. http://sigmasd10.com is
the authoritative site for unbiased information about the pros and cons of the Sigma SD10 digital SLR. This was a minor update. 1. A little more information was added on the cause of the color rendition issues with the Foveon sensor. 2. Changed the 27 links of the definition of a pixel into numbered links, rather than the entire URL. 3. Even though the R-CRV3 Li-Ion option isn't on Sigma's web site yet, I went ahead and changed "No Poor Rechargeable Li-Ion Battery Option," to "Poor Rechargeable Li-Ion Battery Option." 4. Added links to other reviews of the Sigma SD10. If you find any errors or omissions on this site, please let me know. I have made several changes as a result of feedback from rec.photo.digital contributors. Disclaimers ------------ This is a non-commercial, informational site.

Sigma SD10 Web Site Update
"Steven M. Scharf" wrote in message
news snip I see nothing new there about the SD10. The photos I have seen, taken with it have all looked quite good. The only problems I'm aware of (which would stop me from buying this or any camera) a 1. The SD10 has a propensity toward accumulating dirt behind the dirt-shield on the sensor. 2. The SD10 uses solely Sigma lenses. 3. Sigma lenses seem (from the lens Jeff used in his review) to have unsharp patches (bit more grinding needed). 4. The SD10 uses RAW format as opposed to JPEG and that could cause serious difficulties. I do like the Foveon sensor but that's the only thing I like about this camera. I dislike tremendously the tri-sensor arrays of the current digital cameras because of the way they can cause moire problems and because all images are interpolated and are therefore inherantly unsharp. What we get (crudely) when we buy a 3mp camera is a 1mp camera with interpolation. -- Yours Zebedee (Claiming asylum in an attempt to escape paying his debts to Dougal and Florence) |

ah hah hahah ha heh heh heee
lol nothing like a good flaming is there - quiet weekend? Nah then - I've looked for a couple of moments and first techie faus pas (IMHO) is sensor outputs an image Que? What? Run that by me again? so I can plug in the sensor without any supporting hardware or software and see an image? For any1 new to the forum - it's an ongoing metaphysical thang yo'all I think you may need to revisit what a pixel is nah then, even more important The Gimp watcha know? das B "Zebedee" wrote in message ...

i should be more serious - heh heh heh
a sensor (IMHO) outputs data that data goes to an analogue to digital converter (usually acronymed to ADC) when an image of 3.4MP is displayed on an output device it may be in one to one correspondence with the data supplied by the sensor nothing more nothing less inbetween there is quite a lot of digital signal processing digital signal processing and a sensor (any sensor) have limitations and constraints inherent to the method of manufacture and some of the consequences are that the attempt to accurately capture images means that the data and data processing actually introduce corruptions that make the final output display (or print) subject just a little bit dodgy some of these corruptions may be tweaked however, as has always been the case in photography, attempts to improve one aspect of an image introduces corruption in the form of image artefacts or degradations elsewhere in the output image There is a great deal of sophistication in hardware, software and firmware used to optimise image quality i think i shall stop there das B ps - a sensor outputs an image? a hah hah hah haaah dB "Steven M.

Sigma SD10 Web Site Update
hmmmm - something is beginning to make sense
first of all it was the one to one correspondence of JPEG images (image is optimised by displaying the image at the resolution chosen when the JPEG was created. That is what the JPEG spec is there for) Whatever the flaming criticism paranoia expressed in the NG the Foveon sensor does have something going for i. Why, for example, should a 3.4MP Foveon image be almost comparable to a 6MB or 8MP canon image? Doesn't it make sense to have similarity of output image for one-third to one-quarter of the umage output file? Of course it does! I think (thios is all IMHO) the thing going for Foveon sensors and technology is that it maintains a one to one ratio between sensor f=data and output image (c) just in case marketing bods are reading this - you may follow the topic introduced here but accreditation to & permission from das B first if you please :-) No, the reason Foveon is creating shock waves is because maintaining a one to one correspondence seems to minimise artefacting and degradation. Before the flaming starts (a flamed bagal anyone? lol) similarity of image quality at gross diversity of sensor imaging elements? Hasn't the penny dropped yet? das B "bagal" wrote in message ... i should be more serious - heh heh heh a sensor (IMHO) outputs data that data goes to an analogue to digital converter (usually acronymed to ADC) when an image of 3.4MP is displayed on an output device it may be in one to one correspondence with the data supplied by the sensor nothing more nothing less inbetween there is quite a lot of digital signal processing digital signal processing and a sensor (any sensor) have limitations and constraints inherent to the method of manufacture and some of the consequences are that the attempt to accurately capture images means that the data and data processing actually introduce corruptions that make the final output display (or print) subject just a little bit dodgy some of these corruptions may be tweaked however, as has always been the case in photography, attempts to improve one aspect of an image introduces corruption in the form of image artefacts or degradations elsewhere in the output image There is a great deal of sophistication in hardware, software and firmware used to optimise image quality i think i shall stop there das B ps - a sensor outputs an image? a hah hah hah haaah dB "Steven M.
