  • Sent you a PM.
  • I think it is not bad at all. And I think it works better in color. I love BW but in this case, the color adds something to it which is lost in the BW conversion. I like it !
  • Don't you think that from the pixel-peepers point of view, all Quattro settings are worse than the Merrill output? It is either watercolored or noisy. I am surprised that you tried luminance NR. ...
  • Thnx, I think you are right!
  • I used 0.8 Fill Light. More than I typically do but the pricture needed it. I could/should have used some exposure compensation while taking the shot but didn't want to blow the sky.
  • As it turnes out, the German Tornado is a Russian MIG-23. Obviously, a left-over from the German Democratic Republic.
  • Created photo thread Some jets - Out of service
    Some pictures from the Technikmuseum in Speyer, Germany. SD1, 18-35 and 50-500. A Russian MIG 21 A German Tornado The backside of a US F-4 Phantom I don't know what it is, maybe a Sabre ? But the ...
  • Replied in kind of funny
    You are telling us that the quality of your monitor shows you much more information to differentiate between pictures from different cameras. And you post a lot of pictures which your audience ...
  • Reading the posts in this thread reminds me that I seem to be an atypical photographer. I assume, I am too much of a hobby photographer.... (this is not only related to this thread but to a lot ...
  • I think you are right Larry, the earlier pictures are more clean. Full size, there is no real difference, on pixel level the combination of noise reduction, sharpening and contrast makes them look ...
  • Hi Larry, I had a look at your pictures which are well done. I am not a pixel peper but I openend them in original size and 1:1 representation. My first thought was: oops, the typical strange ...
  • Nothing against reading old threads, but did you notice that the guy reported the problem with his DP2M about 18 months ago? He might know by now....
  • You're right, the notation 1:1:4 and the subsampling factor of 4 don't follow the notation in video or TV chroma subsampling. In that context it would be 4:2:2 (or 2:1:1) because we would talk ...
  • Forget to mention, in the final processed image, this relates to 14.75 MP, 19.6 MP and 25.6 MP, respectively. The Merrill sensor with full color sampling, the Quattros with chroma subsampling by a ...
  • Replied in SD1 vs SDQ
    No, the SD1 uses the 46 MP Merrill sensor (RAW files 14.75 Msensels each layer, topology 1:1:1, i.e. 3x14.7 MSensels) thereas the sd Quattro uses the newer 29 MP Quattro sensor of the DPQ models ...
  • This is for sure not what you wanted to say Ted as you know better. DOF comes from refraction and is a geometrical effect. Diffraction kicks in (becomes visible) at higher apertures and has nothing ...
  • Any idea which of the typical RAW converters (from camera makers or software vendors) uses such an adaptive algorithm? You may, as in your example, assume slow varying chroma. What does it mean? ...
  • 1. Pretty useless if you ask me. Unless you typically take pictures of paintings from Piet Mondrian. 2. I don't understand what you mean here. A look-up table? Based on what? Are we still in ...
  • Replied in Redundancy
    I don't know if I find this funny or annoying. As if you don't want to get my point. BTW, neither I nor Truman said that the sampling theory only applies to sine waves. But, surprise, we could have ...
  • Replied in Redundancy
    No, in fact it is a very bad example because it doesn't fit at all to the problem. Once I know that it is a sine wave, 2 samples are enough. But the sensor doesn't know what it acquires. And it is ...
