Producing your own systems photos

Here’s a brief, step by step explanation of how I approach AV system photography.

I'm going to make the assumption that you’re already a practiced photographer, you have a camera that allows you to turn off the flash, manually focus and manually control exposure, and that you have a good understanding of how to use PhotoShop. If that’s not the case, you’re going to have trouble taking this kind of photo and need more training than I'll be able to give you here. Still, these steps should give you an idea of what you'll need to learn.


Part I: In the field

1. Don't overlook the obvious: straighten the chairs, pick up any papers, hide any cables visible in your shot. Stand by the camera and look at the room. Is there anything you should straighten or move or fix?

2.White balance your camera to the lighting in the room. Test your color by downloading a few shots and looking at them on your laptop.

If your camera has a RAW mode and you've purchased the appropriate processing software, shoot the images in RAW. Be sure you shoot a test exposure or two with a neutral gray card you can use to balance the color in your RAW processor later.

3. Make sure you don’t ever move your camera, zoom or focus, once you begin an image.

4. You always need to ‘bracket’ your exposures for this kind of image, that is, shoot a number of exposures above and below what your light meter tells you is correct. But for these, shoot an even wider range, from very dark to obviously washed out.

5. Consider shooting the main image with the projector(s) or monitor(s) turned off. It depends on the particular room, but often the screen image will be much brighter than the rest of the room and it will bleed past the edges of the screen on your photo. Sometimes, too, you’ll get odd reflections on tables or other objects (although you may decide you like the reflections, as I did in the image shown at the top right of this page).

6. I use two different methods for shooting screens.

Method 1: Before you move your camera, shoot the room again exposing specifically for the screen images. This method is faster and easier if you have multiple screen images or if you are shooting only one or two views of the room itself. (If you're shooting in RAW mode, this step will not be necessary, though you may need to shoot a wider series of exposures to be sure you have a good screen shot.)

Unless you're shooting in RAW, be sure to change your camera's white balance setting. For most monitors and projectors, the daylight setting will be pretty close. Consider darkening the room to improve contrast and color.

Method 2: Move the camera and shoot a closeup of each screen image, again possibly with the room darkened.

This method is easier if you only have one or two screen images and will be shooting the room from multiple angles. It can also get you better results, because your screen image will be dead on and thus a little brighter than it would be from an angle. You will also have the opportunity to custom white balance your camera to the screen (or balance it later in your RAW editor), at least if you can send a plain white image to the projector or monitor. (If not, use your camera's daylight setting.)
