Alright, I've purchased some new toys for some product photography. I grabbed a grey card, and a true white/black card with it as well. I've shot that item within the "lighting" used for all of the product shots.
Can I set the grey, white and black settings in camera raw (photoshop)? If so how or can someone explain their method?
Much appreciated.

1) shoot image with grey card
2) open levels... select grey point and select the most neutral point on the grey card you can find. this will get you close.
3) adjust by eye.a grey card will only get you close to true colour. anything in the environment of the photo will effect colour balance. ie: if the floor in the room you're shooting in is a warm wood tone, it will warm up your shot (and change the colour of your grey card). if you're shooting in the woods, the leaves of the trees will shift everything green. etc.
it's not really a science but the grey card will give you a good starting point for colour correction.

- looked all over in raw and couldn't find it....rodzilla
- I'm not sure, I use Capture One and the colour balance is built into the main interface. I don't think theres an eye dropper in RAWTungsten

in camera raw you can use the white balance tool to click on the gray card and it will auto-adjust your colors based on that gray as neutral. it's in the upper left corner in the cr window

another small tip:
when setting the gray point with either curves or levels, beforehand you should make a selection within the gray area and go Filter>Blur>Average. this will eliminate any noise interference when setting the gray point.

Overkill for most people.. but we use Macbeth color charts, you can figure out if your light has non-linear color curves that way.... i.e. with some lighting and workflow tweeking, you can prevent the situation where you keep changing color temp and never quite get all the colors right....
