You can use white balance presets to record custom white balance settings, which you can accurately determine by using the baLens Cap. Each custom white balance reading will be stored in the preset d-0. You can then copy preset d-0 into another preset before taking another reading, which will allow you store up to five preset white balances. See your camera’s owner’s manual for more information about this process.

When lighting conditions change, perform the following procedures.


1. With the baLens cap installed on your lens, put the camera in exposure mode P, S or A. Push the MODE button while turning the main dial until you see P, S, or A in the control panel. Once you have set the white balance you may use any of the camera’s exposure modes.


2. Push the WB button and turn the main dial until PRE appears on the control panel. If you want to use the new preset white balance now, choose preset d-0 by pushing the WB button and turning the sub-command dial until you see d-0 on the display.

3. Let go of the WB button for a moment, then push it again until PRE begins to blink in the control panel. PRE will also be flashing in the control panel and viewfinder frame-count displays.

4. Using the “center squeeze” mechanism, place the baLens Cap on your camera’s lens.
As PRE flashes, take a reference shot of the light falling on your subject. The camera will take a white balance reading and record it in preset d-0, overriding any previously stored value. The white balance reading will be stored in preset d-0 until it is replaced with another reading. No photograph will have been recorded during this process.


5. If the process succeeded, Good will blink in the control panel and Gd will blink in the viewfinder for a few seconds. If the lighting was insufficient or too bright, no Gd will flash in the control panel and viewfinder. You will need to repeat the reading process.
