  • oh, don't worry too much. I said it, because your night photos are with ISO 100. In theory the best dynamic range with the DP2M is with ISO 200. There are a lot of discussions about that, e.g. http ...
  • Great pics! Just in case you don't know: ISO base of the DP2M is 200.
  • Correct. This is a video showing the Ansel's home, and his son talking about the Moonrise: http://www.youtube.com/watch?v=p2cPfjBPTOA
  • I think that you mean a photography (taken and) printed by Ansel Adams himself. Correct?
  • Sorry for my ignorance, but I thought that the Foveon sensor has a equation system like, B + G + R = K1  (Top Layer) G + R = K2         (Middle Layer) R = K3                (Bottom Layer) where ...
  • Looking at the table, the Sony A7R wins. The Quattro is better with the Moire (yes, we know that, Bayer vs Foveon) and in the definition in one corner (but this should be a problem with the lens, ...
  • I can’t keep all the posts of the Quattro. I hope this is not said already. One of the complains of the Merrill’s cameras was that it was quite slow for the image review. It looks that the Quattro ...
  • It looks like a Chamomile. You can have a tea with it :-)
  • If I read it correctly, you are right. From the features (http://www.sigma-global.com/en/download/cameras/sigma-photo-pro/): Features for the RAW data (X3F file) of SIGMA dp2 Quattro: ・Auto (Light ...
  • Sorry, could you give me the name of a 2014’s camera with a better quality (low ISO) than DP2M, that fits in my jacket pocket, and that cost below 420 euros? e.g. Fuji X100S? Canon EOS M? Ricoh GR? ...
  • I find them snapshots. I will not delete them because it looks like holidays photos. I think the composition is really bad, but people can have another opinion. Again this is MY opinion and btw ...
  • If you like blur photography, check Ernst Haas. As you are from Spain, look at "La Suerte De Capa".
  • Replied in Quantification
    Do you think that Leica did a comparison between CMOS and CCD sensors? Maybe Leica engineers though that CMOS was equal than CCD, and the only quantification was monetary? And once Kodak went ...
  • I think of this test as a "good light" test. Yes, ISO goes to 2500 but everything is good illuminated. I would like to see a "low light" test, where you need to go to ISO 2500, e.g. f/2 1/40 ISO ...
  • There is no war in Kiev (and I hope stay like that). But, the beautiful square that you show in the photos is destroyed :-( Kiev, April 2014
  • Replied in Wrong
    [...] [...] Sorry Truman, I can't resist it. Can I do a bit of Aristotelian Logic? 1. All digital sensors are monochrome 2. The Q sensor is not monochrome Then:  The Q sensor is not digital :-)
  • Ollie, I want to explain my flow a bit, that it is similar to Kendall and others. At home I use only Linux. My company give me two Photoshop licences, one for my office iMac and another for ...
  • hey, great. You push the limits here.
  • It was not my intention to compare my photos with other cameras (DP2M vs A7 or DP2M vs 645D). I didn’t put a title like “DP2M state of the art in low light”. I just wanted to point out that some ...
  • Thanks Marco! In fact, I prefer (good) critics than someone saying "nice pic". You think about it, and then you try to improve next time :-)
