Color Checker/White Balance

[iflynething]

I just got the Intro 2020 and am having trouble actually using it's potential.

I shot a wedding this weekend and unfortunately the reception was in a gym. I was able to go to the rehearsal and get some light readings. I did exactly what I thought I was supposed to do and that's to set to custom white balance, place the white balance over the lens and shoot.

When I view the images they are VERY much off and look nothing like what I am seeing. I wish the LCD could be calibrated also. I am trying to get the best color matching possible to make everything sistent. Just to make sure I did everything right, I took the WB reading and since it was off I took a picture of the color check that comes with the ProDisk.

Once in Photoshop I set the white, black and mid points as I have found on some tutorials and while I got it right, it still doesn't look great. I still need to get my monitor calibrate. I have a friend that has the Spyder3 I might be able to use and that might solve some of the issue but it still doesn't fix the white balance issues I am having.

I do shoot in RAW....all the time and it's no problem to fix it later, but I'm the type that I want to get it right in the camera first....less post processing later. I hate it.

What I would like to do is get the color right as far as how my D300 records color and set presets in ACR 4.4 to give an across the board [picture] adjustment as far as tint....a camera profile

Is there anything I can do to get color right? How else do I use the color checker?
