I thank everyone for their information and education.
I use the Paul C. Buff, White-lightning Ultra1800, each flash tube is UV coated. Reflectors are 7 inches. Polarizing filter sheets are over each reflector.
A Schneider B+W UV-IR-CUT filter is mounted first on EF 100 mm f/2.8 Micro L lens, and finally the circular polarizing filter.
I might just see where some of my issues come in. Could it be the cardboard x-rite CC? (I refuse to use the passport CC).
Workflow is camera white balanced with what is supposed to be a white target on one side, and black, gray, and white on the other side. These three shades are for me to determine, exposure. Then, I use the white only side to determine white balance in camera.
Next I image the x-rite cardboard CC. Though, sometimes I have the cardboard CC included in the area along with the original art.
I have two different ways I work with the RAW file. Open in RPP 64 and create the lighting-lens-camera profile with RPP 64. I set RPP 64 for Kodachrome 64. Save the digital file as an RGB TIFF16-bit (BetaRGB). I had been saving the file as Lab TIFF 16-bit.
LR 6 is next, and sizing is done in PS CS5.
I do my best not to change what is digitally captured, in order to preserve the likeness of the original art.
The other way I have my workflow, use LR 6. LR 6 will blend multiple RAW’s in RAW. Skip RPP 64 altogether.
Comments are made that the x-rite CC is not the same as the pigments in the original art work. Therefore I wonder if this may be an issue?
Those using Einsteins’, what size reflector is used?
Many years back, someone in the museum industry, on this forum, told me to use the Schneider B+W UV-IR-CUT filter. Anyone remember who that was? Anyone also using the Schneider B+W UV-IR-CUT filter? Might have been in regards to cobalt blue.
An NEC PA271w, and an NEC PA2721w are profiled with i1Pro and i1 Profiler. Two separate work stations. The Epson Pro 9900 is profiled for each different substrate, with i1 Profiler and read with the i1Pro.
EOS 6D’s are my cameras.
Questions?
Kind Regards,
