Of course this turns into a good thread after the sale is over Honestly though, thanks for the replys.
Edmund, I have read explanations about why the Thomas Knoll ACR method of interpreting color was superior to using an input profile, so I was a little aware of the limitations of ICC profiling for an input device.
bcroslin, I have used the Fors script for calibrating all my cameras using Daylight, Tungsten, and Flourescent light sources. The color I get out of ACR is much better than with the default settings with the D2x, Aptus 75, Aptus 22. I recommend it to all of my friends.
I have recently purchased a P45+. It is because of my success using Fors ACR script to calibrate ACR that I have this interest in PM5 and the SG color checker. I was guessing that I could tweak an input profile in PM5 much like Phase Ones Color Editor, but with more options and control.
From what you say Edmund, I might try editing Phase's profiles for the P45 in PM5 as a starting point to see how it differs from the Capture Color Editor. It seems I might meet with greater success than starting with a home brewed profile.
I did spend the $1250 yesterday. I can use it to profile my Epson if nothing else.
Of course I still think of shooting interiors with Astia, exteriors with Provia, gardens with Velvia, and friends weddings with 400NC. I get a little tired of the "P45 daylight" profile by comparison.
One big downside to input profiling is that it does no good if I use ACR or Lightroom. But for right now with the P45 I would like to maximize it's speed and efficient workflow to get finished looking images before hitting the process button.
