  • Replied in Thanks (nt)
    Of course noise will creep in, unfortunately you've missed my point. SFD is not progressively blending the exposures so for its intended purpose 1EV makes perfect sense, 2EV would be better still.
  • Replied in Thanks (nt)
    -1EV and +3EV with an ETTR baseline, that's following the 4-stops rule. Personally I use 3 exposures but 2 is enough to theoretically eliminate noise from your scene.

    N.B, SFD appears not to use progressive blending. @ushere, SFD takes redundant exposures - you only need 2 of the 7 for it to be effective, that should help regards misalignment. Example of a ...
  • "Usability nightmare"? I wouldn't go that far, I don't have any issues with it. The magazine is written by Bob van Ooik whom posts under BobNL on here and Flickr ; he's a master of both Merrill and ...
  • For portraits, this could be worth a read. Another option, albeit time consuming, is to use a monochrome conversion as a Luminosity layer -- mono offers an altogether different rendering to SPP's ...
  • Darn it, just as I thought that I was going old-school with my DP3M Trichrome... Phase One unveil a Trichromatic digital back :-x
  • Hi George, in this instance I should be thanking you for including the Colour Checker in the shot - I'm experimenting with Trichrome as I dislike SPP for (Merrill) sunsets, your shot has allowed ...
  • Replied in Trichrome lemons
    I'm not a fan of SPP's Merrill colour conversion so I used monochrome instead :-D N.B, the White Balance looks too warm but... I was aiming for colour accuracy with the ColorChecker Passport itself. ...
  • Replied in Foveon Red
    Easiest way to tell Quattro and Merrill apart... red! The same can be observed in the comparison from Joris1632 - the shelves. Out of Focus areas are the other tell, also obvious in the latter ...
  • Handheld trichrome panoramic of the Garonne (Toulouse). SPP exports 3 off 100% R/G/B monochrome images, assembled and colour corrected in Photoshop. So technically cheating but it was forged from ...
  • That was indeed a truism, doh. After a lack of interest when analysing Quattro RAWs, I didn't bother posting my experiments with Merrill conversions and Luminance. And due to running a rather ...
  • I promised Args that I wouldn't post anymore but... I'm sure that he won't mind one last farewell (maybe). One difference between ≤Merrill and Quattro is their source for luminance; Quattro uses ...
  • I'll save you the time that it takes to personally discredit me, as you do others, and I'll simply stop posting.
  • Nope. Facts are that across layers, Merrill can expose with a difference of 2EV, not good for SNR! And if the top layer is correctly exposed, then the bottom will be underexposed and vice versa. ...
  • Merrill's top layer SNR is 160% to that of Quattro with a "white" illuminant. The middle layer's SNR is basically a wash between the 2 sensors (which surprised me) and whilst Merrill's bottom ...
  • Haha, 10 replies but only one example :-D Only used FOV Classic Blue the once, not that exaggerated I'm afraid... Just remembered, that was my absolute first photo with taken my dp0.
  • Yeah it's worth reading/watching some interviews with Kazuto Yamaki, he comes across as very genuine, a great figurehead! His father always wanted SIGMA to be a camera manufacturer hence them ...
  • SIGMA (due to the cost of R&D presumably) have followed a slow tick-tock development cycle - Merrill being the exception, a blind alley? Quattro, I would expect a 20MP mkII with improvements to ...
  • Thanks for confirming. I'm hoping that a) Rick won't mind me posting this and b) that Maceo won't mind my using his image but... this is an example of SFD behaving badly even when, in theory, ...
  • Hi Steve, you seem to be a proponent of SFD, especially for shots like this... but do you know how easy it is to batch export the 7 frames? I've yet to find a suitable target to test SFD but am ...
