D50 vs D65

Hi,

I had a BenQ monitor and calibrated it with my Spyder2PRO.

Now I swapped to an Eizo monitor, which provides D50 and D65 profiles.

When I load the D65 profiles, images look the same as on my BenQ monitor with

its customized profile. When I load the D50 profile, my images look darker than

on the BenQ.

I don't recall selecting a color temperature with the Spdyer2PRO when doing

calibration. Does this mean that I have been unknowningly editing all my photos

at D65 all along?

And am I correct in saying I should be calibrated to D50? Equally important, is

a printer effectively calibrated towards D50?

I note that my photos on my BenQ (I think, at D65) always needed to be

lightened somewhat to get a good print, meaning, I think my monitor was showing

me a darker image than what my printer thought was ok. So would this explain

the discrepancy between my (calibrated) monitor and my (calibrated) printer?

However, what confuses me in all this is that I edit my photos on my BenQ (D65)

monitor, and they seem to be fine when looking at them on other monitors.

Thanks!

The standard adopt by many people including me is gamma 2.2 D65 (or native white point).

I didtn know that a printer was calibrated toward D50?...

A calibrated monitor is one thing, using the rigth ICC profile when printing is another matter..my monitor match almost perfectly what i have on screen, but more important it also match what i send to be printed in magazine or on commercial press.

Im not sure i really understand your problem since it doestn really seem like you have one if all look good and your happy?!

I admit my question was odd, but here is why, and I think the problem is more complex:

I understand monitors should be calibrated to 2.2 D65.

I understand the standard light for commercial viewing is D50, right?

So, frankly, this difference confuses me, but perhaps this is due to radiated vs reflected light, and is irrelevant?

My root problem (on my calibrated BenQ) was that all my printouts seemed to be darker than my monitor, even though I use an Epson 3850 with Epson profiles. So I suspect this has nothing to do with D50 vs D65, and is more likely that my monitor calibration was not so good?

Still interested in the D50 vs D65 question though!

Merci Patrick. Vous etes en Canada ou France?

Ziggy,

All that's important is that you edit in a neutral looking environment-your display. If D65

looks neutral to you, use it. You have no control over the many lighting variants that exist

outside this environment.

Sure, you could create calibrations that reflect the color temp of different external ambient

lighting sources, but why put yourself through such torture. The number be it D65 or D50

written into the profile is all that CM apps look at and decide whether to add red to cool

colors or reduce yellow in warm colors in your previews, but color temp can't make CM

apps or printers change density.

Your printer has nothing to do with your display calibration. Your printer doesn't make

corrections to the tonality of your image according to the makeup of your display profile.

I'ld trust the display calibration before I trust the printer and its canned profile. You may

need to create a custom printer profile and/or check your Photoshop/printer color

handling settings.
