Re: Variations in Color under Fluorescent Lighting

When taking pictures of subjects that are illuminated with fluorescent light using a digital camera it is possible that variations in white balance from image to image can occur. As a result, the overall color cast of the photograph can change depending on the exact instant that the shutter is released even thought the lighting conditions are constant. The reason for this phenomenon is that the color temperature of the light source changes during the power cycle. For normal AC lighting systems, the power goes from full to zero 100 times per second according to the variation in voltage. Incandescent lighting has a high thermal capacity (the filament remains hot) so the temperature and color remain relatively constant. Fluorescent lighting however uses a different method of illumination and the color will change from instant to instant. Our eyes do not detect this change as it happens too fast for us to recognize. However, the camera is able to capture an instant in time that the eye cannot, and when a picture is taken with a fast shutter speed these variations become noticeable. The phenomenon therefore occurs when the shutter speed is comparatively faster than the frequency of the AC power source to the light.

How do you find the white balance on this camera?


This camera does not have a customizable white balance. It does have some presets -- they are:

  • Auto (default)-automatically corrects white
balance. Ideal for general picture taking.

  • Daylight-for pictures in natural lighting.
  • Tungsten-corrects the orange cast of household
light bulbs. Ideal for indoor pictures under tungsten or
halogen lighting without flash.

  • Fluorescent-corrects the green cast of fluorescent
lighting. Ideal for indoor pictures under fluorescent
lighting without flash.

To access them, press the [Menu] button and look for White Balance -- the icon is a Sun and Light Bulb symbol.

Technique on taking images of baseball cards


Greetings sandb27,

Your best route to avoid flash reflection on your cards is to find a lighting situation where you do not rely on flash. I would suggest a small handheld tripod to stabilize the camera and shooting without the flash. You might also try to use the Indoor Mode. Indoor Mode prevents camera shake blur and adjusts the white balance to preserve the subject's true color when working under tungsten or fluorescent lighting.


Thank You,

Agent Dort

Check the WHITE BALANCE settings and the COLOR EFFECTS settings (marked as W. BALANCE and COL. EFFECTS when MENU is pressed).

When you got to the MENU setting, press up or down arrow until you reached either selection, press the left arrow, and you'll see several options under the selected function. In WHITE BALANCE, there's an option whether you'll be shooting under sunny or cloudy skies, tungsten or flourescent lighting, and an option to select Auto or Manually set White Balance. This affects the over all color tone as it compensates the color correction depending on your shooting conditions. Fluorescent lighting for example exhibits blue spectrum, thus setting White Balance to FLUORESCENT will add warm or yellow tones to the photo. Tungsten lighting and sunny conditions exhibits yellow lighting, and setting to the White Balance on this mode will add cool or bluish tone to the picture.

Same with COLOR EFFECTS: settings include WARM, COOL, SEPIA or BLACK AND WHITE (gray scale).

Chances are, you have accidentally set the WHITE BALANCE or COLOR EFFECTS to any of these. To see if this is the problem, try shooting under SIMPLE MODE (Marked with a HEART icon at the rotary dial on top right of the DMC-FZ7). If the problem goes away, then it is with the WHITE BALANCE and the COLOR EFFECTS settings. Try setting the COLOR EFFECTS to "OFF", and the WHITE BALANCE to "AUTO".

If all else fails, then you got a problem with the image sensor of your Panasonic DMC-FZ7 Digicam

YThe colors in my picture have yellow/green color cast.


When you take pictures under certain artificial lighting conditions- such as fluorescent, incandescent, or halogen lighting, the colors in your image may take on a yellow or green cast. You can use HotShots to touch-up the colors; see Chapter 7 for instructions.

White Balance


Color reproduction differs depending on the lighting conditions. For instance, when daylight, the setting sun or indoor lighting is reflected on white paper, the shade of white produced will be slightly different for each. By setting the WB (White Balance), you can achieve more natural-looking color. You can also preview different color tones by trying the different settings under the actual light source, and checking the result on the viewfinder/monitor. You can choose mode from Auto, Preset and One-touch.
