  • Ted, As it only occupied a portion of my screen viewing at 100% or as original, I was also wondering whether it was shot at 2336 x 1568 (DP2M low res / 1.4898 aspect ratio) and then resampled to ...
  • Hello, Ted - As contemplating getting an SD10 or SD15 for outdoor (non-IR) daylight photography, I wonder what the best choice would be for color accuracy. What would be the AFE impact with the SD15 ?
  • Sigma SD15 serial 002645 ISO 100 F4 , 1/125 sec, exp bias 0 step, focal length 55mm, max aperture 4, 35mm focal length equiv 93, EXIF version 0221, SPP 6.2.1
  • I can't find artifacts on the first picture ; on the second one, just the grout around the glass tiles. So the DP1Q dealt with graffiti with flying colors, even at F8. Chris
  • Replied in ality check

  • Looking 1:1, the Quattro sky was decent in the first set, yet the sun reflection on the headlight of the back Jeep was purple unlike the Merrill (?). In the second set, the Quattro sky was not ...
  • Hello, Ted - Could you elaborate on why you can't get on with the Merrills ? Thanks, Chris
  • Hello, Larry - So as to minimize non-Sigma artifacts, I thought it might be worthwhile exporting to 16bpc *.tif with the latest SPP, then take a portion of the sky with clouds and convert it to ...
  • Replied in Fixed
    Sky detail Sea detail I still see that "gradient effect" and not sure whether it was an OOC or some artifacts of post-processing (LR, etc....) Chris
  • Take a look at a blue sky sky 1:1 in pictures taken at ISO100 before making a decision (also finding out firmware and SPP versions, as some aspects evolve). Chris
  • Bristish Airways and Air France operated the Concorde with a subtantial loss, and also it was questionable as to having for instance one flight a day from New York to Paris would really save 3.5 ...
  • Using Rawdigger I recalled that there was some random noise exceeding the Merrill 12-bits quantization, and then taking pictures with the cap on ;-) in a cold room, I was hoping that the upper 4 ...
  • Sorry - I'll point to the filing details http://tsdr.uspto.gov/#caseNumber=86240277&caseType=SERIAL_NO&searchType=statusSearch Tnx, Chris
  • Yes, Nancy - "The sensor at the moment will show very limited range of ISO performance due to small photosites… the sensor currently aimed to use for Videography, monitoring, aviation, and space ...
  • It might be politically correct to say "the sqy is the limit" for subpixel peepers. Chris
  • As a subpixel peeper Chris
  • Look at the water 1:1 at the bottom of this picture : http://pliki.optyczne.pl/em5mk2_praga/hi_res/P2130673.JPG Can anyone explain ? Chris
  • That's why I used to keep track of Merrill cameras serial numbers, and I was checking for gaps as well. Also statistically you can see on sites like Fickr how my different users have the cameras ...
  • Hello, Robert - This is the picture I was looking at : 7296 x 5472 pixels about 17MB Olympus EM5/ii house picture What do you mean by "poster" ? Should I have developed a 9216 x 6912 16-bit tif ...
  • As the top layer of the Quattro sensor has a higher resolution than Merrill, I thought they would use it to test lenses resolving power, especially for consistency with buyers who'll get the SD1Q. ...
