  • The camera draws 1.21 gigawatts of power during shooting...
  • Adobe, sadly. Sigma has always been willing to share code and help. However---I believe that the processing is much different (in Adobe's defense)---it's a different pipeline to process the raw, ...
  • Lin, Yes, I've done tons of photography with black dogs (both show and field). The issues that I've had with the sigma cameras (mainly the SD15) end up to be 'underexposure' of the dogs coat---and ...
  • Replied in Well...
    Mike, Lin: I've had problems with this and black dogs in bright sunlight since the SD15. It is a 'real' problem---it's the low frequency color noise. It doesn't happen very often, but the steers ...

    Laurence, Thanks for the excellent recall, and a trip down memory lane! I love the part where Jim is praising the functionality and performance of SPP versus the Canon software (those were the ...
  • :-D
  • Replied in Exactly
    Andy, I remember that shot as well---it was one of several that convinced me to go for the SD10 as my first dSLR. I can't remember if it was Laurence who shot it or Jim (can't remember the last ...
  • Hey Bill, With the SD10, Seng and I put together a 'package' that included rectangular filters in different IR pass wavelengths that replaced the dust filter---so you could use any lenses you ...
  • Replied in No.
    That's a race to the bottom. Thin margins, and they're not likely to sell many. So while you might like the camera, it's likely to be less commercially successful than the Merrills or Quattros (or ...
  • Bill, I recognize Seng, Dick Lyon(s), and who I believe is Dick Merrill (he's hiding under a hat... :-)). The other two I'm not sure about...
  • That light is so ridiculous, Hulyss, it makes me giggle. Awesome image!
  • Hey Seng, It's beautiful. The original is one of my favorite images too---just jawdropping! Good to see you out and about! Rudi, The founder of the foveon technology (Seng's late husband) is the ...
  • Hi Rick, Thanks for the synopsis. I'm loving the DP3M, and I think I'm going to pick up a DP1Q when it becomes available. We should do a desert trip sometime soon.
  • One of my friends is a VP at Foveon. I don't get carp out of him, except for great conversations about many interesting subjects (but not R&D). With the quattro, Sigma has done the following: 1. ...
  • Replied in Yes and no...
    When you're first figuring out how to use the camera, I think this experience is typical. Once you're more comfortable with what's going on, you can change to more battery-friendly settings and ...
  • The reason I call it CA is it's magenta at the bottom, and green at the top (of the highlights), which is similar to what you'd see on a larger object (one color at one side, the other color at ...
  • They look like chromatic aberration on a specular highlight. It's from a lens---whether it's the big one or the microlens, I couldn't say...
  • Seng, Your posts always make me smile...  Thanks for sharing these!
  • Otherworldly, would be my first description. Very nice, Seng. It looks like you're enjoying your next-gen camera!
  • Try copying the files off of the SD card and on to your hard drive.
