Kodak aqua image cleaner9/21/2023 ![]() Holding the shutter button from when the camera is turned on will not fire a shot. Once it is on it takes approximately 6.8 seconds to take a photo, which is an amazingly long time for a digital camera in today’s market. The V803 is exceptionally hard to turn on, requiring the On button to be held for a few moments. Speed/Timing **– All speed tests were conducted using a Kingston Ultimate 120X 2GB SD Card In a 0.5 second exposure at this ISO, the camera has a mean color accuracy of 12.4 and percent noise level of 2.56, neither of which are good scores. The V803 has a Long Time Exposure menu that allows adjustment of up to 8 second long exposures, but won’t shoot at ISO 400. We also test long exposure performance of cameras in low light, but only at ISO 400 so that we can standardize the test. Overall, the camera is poor in low light, yet performs better than similar budget point-and-shoots, the Casio EX-Z75, and the Olympus FE-230, but worse than the GE G1. Lower ISO settings produce less noise, but won’t let you shoot in as dimly-lit situations. Noise levels are very high at all low light levels, again showing how poor the ISO 1600 setting is on the V803. The V803 doesn’t quite properly expose at 5 lux, showing the camera has clear limits in low light. The EasyShare V803’s color accuracy is poor in low light, but actually improves as the lights are lowered. 60 lux corresponds to a room softly lit by two lamps, 30 lux is approximately a room lit by a single 40 watt bulb, 15 lux is the light from a TV, and 5 lux is about as dark as a room lit by a small nightlight. We lower the light levels to 60, 30, 15, and 5 lux to test the limits of the camera’s sensor. We dim our studio lights to test a camera’s color accuracy and noise levels in less-than-ideal light conditions. ***Click to view the high-resolution image* The Kodak V803 has the worst white balance of any camera we have seen this year. The tungsten preset gives images an odd aqua-colored cast that will only be helpful in shots where you’re going for an "underwater" look, which will probably be never. We have never seen a camera that gives such a strong blue cast to a neutral test chart as the V803’s fluorescent setting. We would suggest using the presets instead of the miserable auto setting, but unfortunately the presets are even less accurate. Photos under fluorescent light fair just as badly, and look yellowish-red. Flash and outdoor shade lighting produces images with a strong blue cast, while under tungsten the images are extremely yellow. The white balance using the Auto setting on the V803 is dismal. We photograph the ColorChecker test chart under flash, fluorescent, outdoor shade, and tungsten lighting to see how accurately it reproduces whites and grays. The Kodak V803 has no manual white balance setting and entirely relies on the auto setting and presets. Poor white balance can give a strong color cast to an image, often either yellow or blue. This is called white balance, and most digital cameras have a manual white balance setting, an auto setting, and presets for different kinds of light. In order to accurately depict colors, a camera must adjust for the different color cast of each kind of light. *Every kind of light source has a slightly different color temperature, such as fluorescent, tungsten, and daylight. Because the V803 lacks manual white balance, the charts show the camera’s tungsten preset white balance performance. The outer squares represent the camera’s colors, the inside squares show the actual color of the ColorChecker corrected for the exposure, and the small rectangle shows the actual color of the ColorChecker in an even exposure. The image below represents the V803’s performance. Some of the tiles in the top row are designed to correspond with sky blues, foliage greens, and flesh tones, while the rest of come from all over the color spectrum. The ColorChecker chart consists of 24 tiles of different colors from around the spectrum. We test color accuracy by photographing an industry standard GretagMacbeth ColorChecker test chart, and then compare the colors the camera reproduces with the known colors of the ColorChecker. Some cameras may boost the blues in skies, making them brilliant but unnatural, and others may shift reds and yellows making faces look either more enlivened, or extremely flushed. However, depending on the camera you’re using, the colors of the landscape and your friend’s faces will turn out very differently. You pull out your camera and snap a photo, capturing the stunning view. ![]() So you’re on a trip with some family or friends, and you come across a beautiful landscape.
