DIY light booth uses 6x Yuji LED VTC D50 modules (2016), which are an excellent D50 simulator although they have no UV content.
Light booth and display must match in brightness and white color.
There is no low or high brightness in display if equivalent ambient light is applied to hard copy (about π times, Lambert):
- 500 lux booth ⇔ near 160nit display (D50 white point, ISO3664+ P2 practical appraisal conditions)
- 300 lux booth ⇔ near 100nit display (typical setup, with custom display white point somewhere between D50-D58)
Lab test image was printed on Delex.es FSF260 photo paper using Epson ET-8550 printer and a custom ICC profile made with ArgyllCMS. It is an inexpensive photo paper (0.45€/each A4 incl. taxes) with satin/luster/semiglossy finish, big gamut and deep blacks (L* ~5, Dmax ~2.25).
Some colors on strawberries and other places are out of gamut in digital copy when softproofing to custom profile for this paper and other papers, as expected for this test image.
Delex FSF60 and other Delex RC paper have an extremely high OBA content (optical brightener agents, fluorescense under UV light), so if you simulate paper color on softproof it will show more bluer than printed copy under Yuji VTC D50 LED.
Why? because if ICC printer profile was made by measuring under M0/M1 conditions, ICC profile data will store this paper fluorescence due to UV content in M1/M0, while Yuji VTC D50 have no UV.
For this reason "simulate paper color" was disabled on softproof options for this test.
Yuji VTC D50 LED uses a violet LED + RGB phosphors to simulate D50 spectral power distribution. Even with no UV, Delex RC papers with high OBA content have an small blue-pink tint that softproof is not simulating, so display looks a bit warmer in this photo.
Also there are other sources of color mismatch like the ones introduced by camera being feed by light with narrow spectral peaks from Eizo CS2731 backlight (W-LED PFS phosphor). A colorcheker is unlikely to correct this on a photo of a screen.
Also remember that softproof assumes that display whitepoint matches ambient light source, so any paper color cast stored in ICC profile will be applied equally on screen.
That's why softproofing OBA papers with "simulate paper white" option on displays calibrated to D65 show a huge blue shift. This is one reason to calibrate to warmer whitepoint around D50 (+ visual match tweaks) if you want to make comparisons with hardcopy under D50 light or close simulator like these Yuji LEDs.
Small brightness and white color mismatches can be solved by manual tweaking display (white color and nits) or booth (lux).
Eizo ColorNavigator7 has an optional post calibration stage using hardware calibration to fix these issues and get a visual match, but this post calibration adjustment was not applied here to show you these effects.
A custom ColorChecker Classic camera profile for Yuji VTC D50 LED was applied to this image.
Caught a beautiful sunset while home for the weekend after returning from a wedding in Pensacola. This was taken off Whitepoint in Destin, FL
