So far it hasn't been so widespread to make me go the extra step. I'm a little reluctant to do it because I'm quite comfortable with LR (much less with PS though) and learning another program.

Our new Capture One Basics class might be helpful to you.

There's also an older set of tutorials on this website (luminous landscape) based on, IIRC, Capture One 10.

There's also lots of free webinars on

I'm biased as heck, but in 10 years of teaching C1 I find it pretty rare for someone to switch back to LR after learning C1. LR is faster and more intuitive to learn at first, but C1 is better in just about every other way.

DNG files store the metadata inside them, no xmp generated, the same with tiff, psd, psb, etc.

I know you like to read yourself, but please spare the epistles.

You post 10 times as me on this topic. What you are doing it's called projection.

Thank you for your attention to my question.
I am looking for color reproduction.
Now I'm shooting on IQ 280 and H5D-50c
They have a great color, but often I need more accuracy in this
Will I get a more accurate color with the H4D-200 MS?

It's a myth that multishot helps with general/global/overall color accuracy.

Multishot can help with the color accuracy of specific subject detail in the case that the detail is 1) stochastic and 2) nearly exactly one pixel in size. So for example in a tightly woven fabric with randomly colored threads a multishot camera will more accurately render each fiber if you shoot it such that each thread is ~1 pixel in size. If you are not using a multishot camera, in that scenario, you can simply move a bit closer (such that the detail is more than one pixel in size) and stitch to capture the entire object. We have a free tool called  DT Batch Stitch to aid with that if you are doing it for a batch of different objects. Each of those two approaches (moving the sensor as in a multishot back, or moving the subject as in stitching) has pros and cons.

Multishot also does gain some resolution. You should measure yourself with an ISA Test Target or other FADGI/ISO/METAMORFOZE compliant target what amount of actual gain it provides, as even the slightest vibration of the camera or subject, or any mis-calibration of the camera can lead to considerably less resolution gain than advertised. Many comparisons you'll find published on the internet are comparing the multishot-mode and single-shot mode of the same camera, but forgetting that the manufacturers of multishot camera have significantly less-advanced raw processing math for single-shot captures. A more salient comparison would be a best-in-class single-shot raw to a best-in-class multi-shot raw; this will absolutely show advantages (assuming zero vibration, very good lens, ideal aperture, etc) just much less advantage than you'd think based on the stated resolution of each.

In the last decade nearly all US institutions of cultural heritage have moved away from multishot cameras, which were, in the 2000s and into the early 2010s, quite popular in those settings. In that time improvements to single-shot resolution and improvements to single-shot raw file processing have made and potential advantage of multishot are nearly always far less important than other considerations.

If you do decide to get a multishot back, especially (though not exclusively) if you're buying it used, make sure to test for the proper calibration of the back and look, at 200-400%, carefully for any artifacts or banding, when using multishot mode.

If you're struggling with color accuracy with your IQ280 or H5D-50c I would suggest reviewing our DT Digitization Guide for Reflective Materials for a step-by-step workflow for both understanding, calibrating, and empirically evaluating color accuracy. I would also suggest BasIIColor which is referenced in those guides and the DT NGTv2 target developed with the Library of Congress. Elements of good color include a good sensor (you have two; the 80mp sensor was a hair better than the 50mp sensor, but both were very good by nearly any measure, meaningfully surpassed only by the 100mp, 100mp Trichromatic and 150mp sensors), good color calibration (BasIIColor or the art reproduction profiles in Capture One CH), and good illumination (strobe is good, better still is a flat spectrum high-CRI, high-CQS LED like the DT Photon XL). You should get *excellent* color results with your current gear if your illuminant is of high quality and your color calibration process is sound; if you aren't then I'd focus on that rather than a new camera, to improve your color accuracy.

Notably, color itself is a fickle beast. We did a free webinar recently with Dr. Wyble, on the nature of color and color measurement, specifically in the context of art and other CH institutional digitization; you can rewatch the recording here. The point being that some "problems" with color are inherent in what color is: a sensation of the viewer, rather than an objective characteristic of the object. Objects have spectral reflectivity, which our eyes/brains/minds process into the experience of a color; it's like if you could only hear an overall effect/feeling of a musical chord, and not the individual notes that combine to form those chords. Short of multispectral-based capture and spectrally matched physical reproduction no single-shot or multi-shot camera can resolve all "color problems" you might run into. Though, to be clear, 99% of the time the answer is not more complex than a basic workflow issue like white balance, even fielding, exposure, color profile, or method of proofing.

You may also find our DT Digitization 101 Online Class helpful, as this is a class that over 500 staff at Cultural Heritage institutions have taken as professional development. The 201 in-person class can also be recommended. Both of those classes focus more on library/museum/archive staff and the service bureaus that do work for them.

So in summary, I can reduce my advice above to
1) Test for yourself before purchase; do not take my (or anyone else's) word on what results you should expect based on the spec sheets
2) Investigate whether a change in your current workflow (profiling, illumination, even-fielding, proofing methods) can address your color issues using your current camera, before investing in any new camera

Bias Disclosure: DT chooses not to sell any multishot cameras, so must be considered biased.

You do you, and I do me works in many situations and that's good.
However, it's much more problematic when the doctors and dentists stop doing them.

Indeed, unless when the "I do me" starts affecting others, like health care professionals (or me persomally)..

My wife and I took her car out for a drive this afternoon to charge its battery, since it's been sitting idle for a month.  On Monday, the county in Maryland where we live will begin to relax its restrictions on "non-essential" business activity, so we headed out to a couple of local shopping malls to get one last look at them before the retail outlets begin to offer "curbside delivery" of online and phone orders.  Except for a teenager who appeared to be practicing for a driver's license test and a guy on a motorbike who couldn't resist the lure of an empty parking lot, both malls had the appearance of a location shoot for a dystopian science fiction movie.

I suspect that's an oversimplification, but I do think the monarchical tradition of top-down government in Europe has influenced cultural attitudes in a way that differs from the libertarian tradition of bottom-up government in the United States.

Not sure about that. "Monarchical tradition" will mean a lot of different things to different people. The European Monachs of now, are not in the same position as they were once. After all, "Enlightenment" is a "European" concept of the late 17th and 18th centuries, and thinking has evolved since then.

I've long had the impression that the tendency in Europe is to assume that everything which is not permitted is forbidden, while in the United States the assumption is that everything which is not forbidden is permitted.  The Brits and the Dutch strike me as tending more toward the libertarian approach than the middle and Eastern Europeans.

Generalizing, that could be a correct observation (although we do test the boundaries of what's allowed/forbidden, depending on nationality), and I can really only speak as a Dutchman, not for the Dutch, let alone for Europeans  ;D.
In generall, the Dutch can come across as relatively blunt/sober, but honest.

But cultural generalizations based on personal impressions rather than objective evidence should always be made with caution and skepticism, not least by those offering them.  North American* and European democracies all value personal freedom and all of them impose restrictions on the unfettered exercise of it.  And the populist movements that have recently popped up on both sides of the Atlantic all seem to have authoritarian overtones.

Quite so.

I (we?) consider that one's freedom ends where it infringes on that of another. Of course we cannot consider anyone's freedoms, because there are a lot of idoits around. But there are a lot of shared values, and visions to improve on those.

I prefer the second. The surrounding rock provides a nice frame.
