Why isn't my wall white in these shots? I took them with ISO 400, 60mm, bouce flash 420EX, on portrait mode. Has it got something to do with white balance? and the 18% grey card? If so, how? Why?

Light dissipates with the inverse square of the distance. The flash coordinates with the meter to put enough light on your subject, but it cannot at the same time throw more light on the wall behind them. If you want the backdrop white, you'll need a separate light on it.

If you really want "white", then the walls need to be 2.5 stops brighter than the subject. FYI - If you want "black", make the wall 3 stops darker than your subject. Assuming you don't have a hand meter, you'll need to measure with your camera's meter. Here's what you need to do - Go to the camera store and buy a "graycard" as large as they have - at least 8x10. Now, when you take the picture, hold the graycard up to the wall, get your camera close to it (don't worry about being in focus), take a reading and make note of it. Then put the gray card in front of your subject (at the same angle it was on the wall) and take another reading. The readings will need to be 2.5 stops apart to assure a white wall. If not, you'll need to introduce some more light to the wall, or take some off the subject, either way, until you achieve your target 2.5 stops. To salvage what you have, you can adjust your highlight control in Levels (assuming you have PS), by sliding it a little to the left. All this said, I personally think you will ruin what are ok shots by introducing a harsh white. Michael H. Cothran www.mhcphoto.net

You could light the wall with a slave flash but I'm with Michael. The photos look good as they are.

Thanks for your responses! I have purchased a grey card (before I read this post!) But I suppose I can't aske for much more considering I don't have a studio and just take the photos at my clients homes. I am glad you like the shots. Michael - Thanks also for your info on "unsharp mask" last week!!! Much appreciated!!!
