With deference and respect to Mr. Smith and the other learned members participating in this Thread I have to take exception to one comment in this Thread concerning Histograms.

From my somewhat limited knowledge a proper Histogram is an indicated of a properly exposed image and there is really no need to photograph a Gray Card or a White Card or any other card for that matter in order to get a good Histogram and therefore a good image.

I try whenever possible to photograph on Manual and I was doing this last weekend during a shoot with a very popular model when I dropped my light meter and went into a state of utter panic. I didn't want to end the shoot because it might have been a month or more before we could re-schedule and I didn't want to "guess" at my exposures because the light was changing rapidly and I didn't want to photograph on "Program" mode so I had the idea to bracket a couple of exposures using my light meter as a center point and the Histogram function of my camera as confirmation.

Once I had adjusted my meter to give me a good Histogram I was once again set to go and this was confirmed when I uploaded my images into my computer and view them in Photoshop. The Histograms were spot on.

Please note that this was my experience and may not be representative of your results and then of course there is the possibility that it was just plain dumb luck on my part but it worked and save my shoot. Nuff said!
