    I received a reply from support; they say that to avoid these sales, you need to opt out of "novel use" (in April).


    Where do you see if a sale is "novel use" (I looked at the sales report and the sales history, but it doesn't say "novel use" anywhere), and are "novel use" all novel use prices this low?


    I got a clarification now. The part about "novel use" was a mistake (on the side of support), apparently you need to opt out of distributor sales to avoid these sales. Strange, though, that opting out of sales to China isn't enough.

    Yes new 14" MBP - all the new ones have these XDR screens. I don't think it is a good idea to use a slider though as it is not consisten and too easily changed. Better to use the Apple brightness calibrations which appear pretty exact.


    In the screenshot above, I only used the slider to exemplify the brightness of the Photography (P3-D65) preset with Maximum Luminance set to 50 – brightness isn't recorded in screenshots, and this seemed like the easiest way of showing how bright 50 appears.

    I don't understand as 50 is incredibly low in itself. If I use the Digital Cinema preset which defaults to 48 the screen looks really dim - white looks like a light grey. I never go below 90 for photography and 80 would be an absolute minimum.  


    Is that with a similar screen?


    A custom preset based on Photography (P3-D65) but with Maximum Luminance set to 50, I get more or less the same brightness as with this preset and slider setting:

    The default for Photography setting is 160 (not 50 as you say) and you can just change that and save it. It's the box that says SDR (Standard Dynamic Range) - ignore the HDR box and related options - they are for video. The recommendation is generally between 80-120 cd/m² - I use 90 for print matching. You can also play with the colour by changing the white point coordinates. Working on copies has no effect on the originals as far as I know. 


    I'm aware of the default of 160, what I mean is that it doesn't seem to be possible to set the brightness at a lower value than 50. If you set it at, say, 40, it will revert to 50.


    Here's an example.




    If I save the above preset, and then make a new custom preset on the basis of the above, Maximum Luminance has reverted to 50:




    I find that 50 is too bright to work with for a longer time.

  5. I wonder if anyone here can help answer a question I've had for a while and now finally am getting around to asking. Some photos have a smooth, photorealism-like quality – a little like this painting by Don Eddy, "Untitled (4 VWs)" (1971):





    Here are a few examples – I just came across these; I'm not particularly interested in cars, but noticed this particular quality/effect again – all from Lienhard Racing Photography on Twitter (if it isn't OK to embed photos from Twitter here, please someone let me know and I'll remove them and just leave the links):











    Does anyone here know how this quality is achieved? Is it done by some sort of colour grading or a particular editing procedure?


    (I know, I could just ask the photographer on Twitter, but it didn't seem quite right ask for technical explanations there.)

    I haven't encountered the term "adjustment mask" when using Capture One Express for Sony, so I guess it probably applies only to Capture One Pro, which has a lot more features. However, even with the stripped down Express version I often have to go back and re-import images and start again from scratch. Losing adjustments definitely seems to be a weakness in the software. I sometimes use DxO as well, and it's much better in this regard. However, I'm not fond of it's keystone adjustment tools either.


    P.S. In Express, there are options to "copy adjustments to the primary variant" and "apply adjustments to the primary variant", which I find totally confusing. I have no idea what they are supposed to do or when to use them, so I leave them alone. This might be (?) causing me to lose adjustments.


    An adjustment mask is just a mask contained in layer, this feature should be in the Express version too.


    A variant is an instance of an image; "the primary variant" would be the main instance of an image. So if you have multiple variants (instances/virtual copies) of an image, you can copy the settings/adjustments from one and apply it to another.

    Yes, I've noticed that the adjustments disappear sometimes. I thought that I must be doing something wrong -- i.e. not saving them manually before closing edited files, which I believe you can do.  I don't think that making keystone adjustments on 16-bit TIFS results in much if any destruction, certainly none that I can see in the histograms, but I'm no expert (and understatement) on this stuff. I won't be upgrading to Capture One Pro because I don't need all the extra features. Sorry to hear that it didn't work out for you. Guess Adobe will just continue to get richer and richer...


    The adjustment mask issue is discussed in the Capture One forum. Quite a few users seem to be affected by it and Capture One support says that there's no workaround that they know of.


    Regarding destructive/nondestructive editing, what I meant was that Capture One and Lightroom, for instance, leave the image files untouched, and once you leave Capture One/Lightroom to continue working on an image in, say, Photoshop, you're working on an exported file (destructively) and can no longer go back and change previous adjustments in Capture One/Lightroom without then having to export the image again and start all over in Photoshop.

    I don't like the auto keystone tool in Capture 1 Express for Sony, so I continue to use a little program called PTLens to make precise vertical/horizontal corrections. I have it installed as a PS Elements plugin. BTW, have you backed up your catalogue, Thomas? I haven't because I don't really use the catalogue feature, but perhaps backing up would help save adjustments.


    I have regular backups, but the problem is that adjustment masks disappear after the program is closed, and I don't think they would be retained in the backups either. As for the keystone adjustments, I prefer editing nondestructively so that I can always go back and make further adjustments. So for now, I've returned to Lightroom.


  9. An update to this thread.


    I made the attempt to switch from Lightroom to Capture One, at least partly, after the update to Capture One 20. After spending 8 months now trying to use Capture One I've come to regard this as a mistake, and Capture One, the software and the company, as unreliable.


    The first major issue I ran into was the severe limitations of Capture One's keystone correction tool, and the fact that simultaneous vertical and horizontal keystone correction doesn't work (what should be 90° angles come out as anything but 90° angles). Though Capture One has confirmed the issue, there's no indication that it will be fixed.


    The second major issue is that many adjustments are lost when the program is closed, something the the company is aware of but has so far been unable to solve. This has been going on for months and a fix may still be months away.


    In addition to these two issues, there's slow/unreliable customer support, lack of support for many standard lenses and cameras, etc. All in all, the advantages that Capture One may have over Lightroom, and it does have some, are more than outweighed by its lacks and disadvantages.
