Many thanks Andrew,
- for clearing the way
so that we can return to the OP’s question which I for one find interesting:
Ok, I know that this is mostly an unanswerable question but I gota at least try.
Think of it as the photographic equivalent of a controlled crash landing.
Does anyone have any thoughts about what to set your luminance target for your display in preparing files for websites?
I am calibrating my monitors with i1 software & hardware.
This is what I set up for targets...
White point = D65
Luminance = 120
To quote from the
whitepaper which I had referenced earlier:
>> Transforming scene-referred data with a 100,000:1 dynamic range into a print is a complex and subjective process. Any two viewers will disagree on what looks best. Transforming a 400:1 output-referred image to 300:1 or 200:1 is pretty straightforward and most people will be happy with a simple fixed method that is the same for all their photographs. Although the photographic industry still has not fixed a universal standard,
most JPEGs and other output-referred images have a target dynamic range of about 400:1. By design, this also compares favorably with computer displays, so the images look correct on your screen as well. ... <<
… which makes me believe that there must be a kind of standard for the white luminance [cd/m2],
e.g. with the monitors in the labs of a camera manufacturer, where the engineers work on the algorithms for in-camera-JPEG conversion. At least that's what I would assume that happens.
So following the logic of the above quote, when prints correspond to an avg. 250:1 dyn. range,
and assuming that ca. 125 cd/m2 on screen work for print-image-matching,
it makes a black luminance of 0.5 cd/m2,
and with a 400:1 monitor dyn. range,
it finally points to a white luminance of
200 cd/m2.
A lot of assumptions here as I have to admit, maybe too simplifying (?),
however, in practice it corresponds (roughly) to my monitor's output and brightness setting for the given purpose.
