  • The film is 60 mm wide, but it isn't used edge to edge, 1.5 – 2 mm of both edges is used to keep the film flat, mostly 2 mm in modern cameras. I've got 69 cameras of various ages, and there is ...
  • 645 on roll film is 56 mm x 41.5 mm = 2324 sq.mm (or 2 1/4" x 1 5/8" which is slightly larger.)
  • Here is a sample with Macro-Elmarit on 10 Mp Nikon 1 V1, pixel density corresponds to about 32 Mp on APS-C, magnification is about 1:0.73 re FX. OOC JPEG, hand held shot in Movie Mode in order to ...
  • Handheld, 72 mm  is near enough. I know for sure that OOC JPEG and SPP do not use the whole sensor area as dcraw conversion gives a slightly larger net area, i.e., about 4810 pixels wide, which ...
  • Here is a quick, handheld test shot. AF locked when the distance from the sensor plane mark (to the left of the power button) to the ruler was about the minimum. As expected, about 72 mm of the ...
  • Replied in Image Circle
    Focal length settings
  • DP3M will focus down to 22.6 cm, 1:3 magnification ratio
  • The chromatic aberration phenomenon in the Merrill photo is a problem with the DP1M lens, DP2M and DP3M lenses are much better overall. Secondly, this part of the test image is too much for ...

  • Yeah, nothing new, per se. However, for me, the problem is the lack of micro contrast in the Merrill SPP B&W conversions. Why bother to use SPP at all when I can get roughly equal results with ...
  • Here are two B&W crop example conversions nearer to your case. View at the full resolution and consider the leaves. There is no need to tell which is which.
  • It is not so much sharpness per se as the ability to differentiate between minor shade differences. I looked at your fern image and I think it might look a little bit different if you have the X3F ...
  • Here is, once more, the "Blue" output from the color mixer: then a version separated from the SOOC JPEG: and finally, a version separated from the SPP produced X3F color version: Observing, e.g., ...
  • OK, I played for a while with dcraw and setting -b 0.9 gives optimal white level without clipping except for some reflections from the gilded parts of the left-hand clock, here is a crop from the ...
  • Have a look at the roof below the right-hand clock – the vertical seams are more or less invisible at the full resolution even without NR. I just wonder what kind of PP would be able to recover ...
  • Created discussion thread Merrill B & W, Part 2
    "The Merrill look" is largely based on the micro-contrast of Merrill photos. Inspecting  B & W SPP converted Merrill photos, I noticed that this micro-contrast was mostly absent. Here is, again, ...
  • Created discussion thread Merrill B & W, Part 1
    I've done some experimenting concerning Merrill B & W conversion. First of all, I got rid of a misconception probably most of us have harbored, the idea that the SPP color mixer can select a pure ...
  • Replied in Merrill Blues
    I don't remember reading, but anyway most of my reading was many years ago. I've done some experimenting, and it turned out that too much deduction isn't required. I'll do some postings concerning ...
  • Replied in Merrill Blues
    Here is 5.5.3, Exposure -0.4, Fill Light +0.4, "pure" Blue: Even the "pure" settings of the color mixer use all layers, and the differences between the R, B and G B&W versions can sometimes be ...
  • Thanks! Sadly, that set of pages is quite out of date. I replaced my EOS5D/350D pair with a pair of Nikon 1 V1's and never looked back. Here is a size comparison between two, for many purposes ...
