When photographing small, reflective objects, I use blue EBW bulbs with a 4800K rating in external floods. They're expensive, available only from a store on the other side of town, and have a short life. Incandescent (tungsten) bulbs have a 3000K output, and give the images a very yellowish tinge. I shoot on a white background.
I shoot with a calibration card in the background so I can set the black, white, and gray points in Curves. That adjusts the yellow out, but it makes the object look stark.
Is there a way of adjusting the image in Photoshop 7 to match the 4800K bulb results with 3000K tungstens? Preferably a series of steps that can be made into an action?

Try the 'Color Temperature and Exposure Correction' plugin ... at the Adobe Studio web site or directly from the author(s) at

You do not mention what kind of camera you use, but because you are talking about Photoshop afterwards, I presume it's a digital camera. Most digital cameras have manual white balance settings for a range of lighting conditions, including tungsten. I would start there before trying to correct anything in Photoshop.
