  • Same 2 U 2 but was that SD1M Merrill or DP1 or 2 or 3 Merrill? . . . . . . or both . .
  • That 24-70mm is a big old lens had one for a while on the SD9 but that was certainly a heavy combo. Trying 24-60mm EX DG f/2.8 on the SD14 as we speak but finding manual focusing not that easy (45 ...
  • Merrie Xmas to All . . No need to differentiate between early and late models, eh?
  • Impossible to "equalize" colors from two different converters, so might as well forget this thread.
  • Indeed the contrast with the early cameras is odious, said he, beating the dead horse. I sold a DP2M for that very reason. Today, I was snapping a clock with the SD14 in LO res . . . SPP 3.5 opens ...
  • I must admit to a slight fascination with that horrible green.magenta blotching that occurs at certain but not all shadow levels. I've long ago decided that the root cause is the severe matrices ...
  • As I look at my monitor screen my eyes dart around subconciously while taking in the content. Still I am most comfortable viewing the 15" width at about 18", notwithstanding peripheral vision, ...
  • Absolutely. Look at the MP specs where they added up the layer counts to get a big number rather than size of the actual image produced. Not wishing to re-start that discussion, BTW, nor wishing ...
  • Sadly, no. I saved that image from from SPP with various slider settings, saved the graph for each one and picked the one that looked "neutral" to me. For that camera's X3Fs -0.7 was about right ...
  • I found the test results - it was a SD10 shot. Here's the one that shows the sharpening. First, a look at a conversion of just the raw data in the X3F file, converted to a composite TIFF: As we can ...
  • Yes, but please bear in mind that I was referring to non-Merrills etc and my tests were done with SD9 or SD10 images processed by SPP 3.5.2, IIRC. Also, your understanding does assume that the ...
  • Replied in Current Events
    Missed your post yesterday, Laurence, too busy mouthing off about M vs Q :-( A poignant tale about E.W. Smith and most inspiring, thanks for the link and best wishes for a continuing mental ...
  • For my non-Merrill/Quattros you get a fair dose of NR whether you like it or not. Comparing low tones in the same image between DCraw and SPP tells the tale. ACR is even worse (some would say ...
  • Spectacular but not many fields there :-( In England, this was my beast (part owner): Rollason Condor, 100 HP Rolls-Royce, two-seater side-by-side - not many built I learnt to fly in it at Sturgate ...
  • Hello Vitée I like the Aeromatic designs. My most complicated is this limited edition Glycine Airman: 150 made. You can see my others here: http://kronometric.org/tcw/
  • Thanks Gents, Yes, I too thought it was wood but when it arrived the package weight soon dispelled that notion.
  • Thanks for the references, Scott. I wasn't disagreeing, by the way. Theoretically the Quattro DR should be "better" with those bigger layer pixels. Wish I could afford that fancy Imatest stuff . . ...
  • Indeed many posts in this forum say the same thing. The consensus has been -1.8, IIRC, but plenty of folks have disagreed with that number. Bharat has said in another thread that his printer is not ...
  • Created discussions My Other Hobby . .
    . . is buying watches, fixing and re-selling them if they are not keepers. From eBay (Seller's image): Seller's shot, camera unknown, not bad by eBay standards! After fixing it up: SD14 with 50mm ...
  • I've some film snaps in a box somewhere . . I worked up there on-site in the Arctic circle near Deadhorse for about 4 months in '87/'88. Wasn't much of photographer back then, and nothing's changed ...
