Exposure meters are designed on the premise that the scene is an average, middle gray, in brightness. If you take a picture of a white dog playing in the snow, the camera will try to make the picture come out middle gray (a gray dog playing in gray snow). If you take a picture of a black cat sitting on black asphalt, the camera will try to make the picture come out middle gray (a gray cat sitting on gray ground).

If the white background is dominating the scene, the camera will reduce exposure to try to make the entire scene come out middle gray. The solution is to meter on something else. Move in close and fill the frame with the subject, press the AE-LOCK button, then move back, compose the picture, and take the shot. For full details, refer to the "Shooting with the exposure locked --- AE-LOCK" section in the manual (page 52 in my copy).

If you're taking a lot of pictures, you might want to switch to Manual mode and set the exposure accordingly.

Why is the white background not white?


This is a common problem. The metering and light balance are the reasons that you are having problems achieving good results with your photos.

All cameras on the auto cycle are calibrated for 18% gray. Another words a photo of all white results in 18% gray. A photo of black results in 18% gray. The camera adjusts the shutter speed and aperture to achieve an average light level of 18%. That is why photos of snow always appear gray. To compensate for this characteristic of the cameras an 18 % gray panel is held in front of the camera and than the settings are set.manually. The metering in the camera is now locked and using the same light levels objects will be in their natural level.

A second problem is the white balance. Using flash avoids some of these problems. Adjusting the camera for source lighting type will help the most. The light balance is the cause of discoloration of the objects in the photo. Usually the camera white balance can be set for auto, incandescent, fluorescent, outdoor or flash,

Use a manual setting if it is available on you camera, You need to adjust the settings until you get acceptable results. If the photo is dark add light by reducing the aperture number to a lower number allowing more light. After the aperture is open wide(lowest number) increase the exposure to longer time. With very low light levels a tripod may be necessary.. After doing this once record the numbers for next time.

My hitachi 53udx10b was supposedly just serviced but the picture is extremely blue. Have tried adjusting picture to no avail. Help.


I am going to tell you a simple thing to do to know what your problem may be.

With the set on turn the color all the way to zero. Go to a channel if you can that is in black and white. What color is the screen?

If the answer is that it is blue in the background whoever serviced the set did not and could have removed front speaker grill and inspection plate behind it; there is a black plastic block with three screen controls (red,green,blue) and 3 focus controls (do not touch the focus ones.)

I suspect if the blue screen is there a slight adjustment of the blue screen down will correct this.

The picture with the color at zero should be black and white or gray. If blue is background color it will also be with color.

This is called gray scale; picture with color off has to be gray or black and white.

Before you rate this solution if you have questions make a comment right here and I will advise you.

CAN YOU PLEASE EXPLAIN TO TO ME WHAT IS EV COMPENSATION AND HOW DOES IT WORK


EV compensation is "Exposure Value compensation". The camera contains an exposure meter which determines how much light is on the scene and sets the exposure appropriately. However, this meter does not know WHAT you're taking a picture of, nor does it know what effect you're going for. The best it can do is to assume you're taking a picture of an "average" scene and want it to be of "average" brightness. It does this by assuming the scene is "middle gray," halfway between black and white. Most of the time this works fine, because most scenes are, well, average.
However, this is not always the case. Suppose you're taking a picture of a white dog playing in the snow. Almost everything in the scene is bright white, but the camera doesn't know that. It tries to make the scene middle gray, and the result is that you get a gray dog playing in gray snow.
On the other hand, suppose you're taking a picture of a black cat sleeping on the hood of a black car. Here everything is black, but the camera doesn't know it. It tries to make an average scene, resulting in a gray cat sleeping on a gray car.
EV compensation allows you to override the camera's exposure setting. In the first example, you'd want to add two or three stops (positive EV compensation) to force the camera to render the dog and snow as white instead of gray. In the second example, you'd want to subtract a stop or two (negative EV compensation) to render the cat black instead of gray.
How much EV compensation is correct? Well, that depends on the scene. With a digital camera, you can look at the picture and see whether the dog looks white or the cat looks black. Film photographers take lots of shot, using various levels of EV compensation, so that one of them would come out right.

Exposure Compensation (-2.0EV to +2.0EV in 1/3EV increments) whats best for cybershot p71


That depends on the current situation. The exposure compensation merely subtracts or adds exposure to the "best" setting as determined by the camera's meter. The camera works on the assumption that your subject is composed of "middle gray" tones.

For a backlit subject, for example, you might want to add some exposure to bring out details in the subject at the expense of blowing out the highlights in the background. If you're taking a picture of a black cat sitting on black asphalt, you'd probably want to subtract exposure so you don't get a gray cat on a gray background. If you have a white dog in the snow, you'd want to add exposure so you don't get a gray dog on a gray background.

Again, there is no such thing as a "best" setting. There is only a "best" setting for a particular picture-taking situation, and even then the setting depends on your artistic inclinations.

I take pictures of white puppies on the same table in the same room.. some of the lighting is fine, some dark could it be the sandisk..??


Most likely it's the camera. Almost all cameras are designed to meter the scene as a medium gray. If you photograph white puppies in the snow, the camera will try to make the whole picture come out a medium gray, leading to gray puppies in gray snow. If you photograph black puppies in a coal bin, the camera will again try to make the whole picture come out a medium gray, leading to gray puppies in gray coal.

For this reason most cameras provide some means of adjusting the exposure. Since you didn't specify the make and model of your camera, I can't tell you exactly how to do it. Please look in the manual under "Exposure Compensation."

Problem with phaser


Phaser 2135 Printer: Resolving dirty looking background or gray haze

Description: Tiny speckles of toner scattered all over the page, even in areas of the page that should be blank.
  1. Make sure the media being used is supported by the Phaser 2135 printer.
  2. Inspect imaging drums for any signs of leakage or excess toner that could be falling onto the print as it travels though the printer. Any leaking imaging drums should be replaced.
  3. Verify environmental conditions. See article Dealing with humidity, humidifiers. If the environmental conditions are not within the specified range, the printer should be moved before trying to troubleshoot the cause to the background toner.
  4. Determine if any of the imaging drums were exposed to light for an extended period of time (more than 10 minutes). If so, then Replace the imaging drum. (Xerox is not responsible for any imaging drums that have been damaged by over exposure to light.)
Additional Recommendations:
Background toner may increase, if printing occurs at temperatures towards the higher end of the specified operating temperature range. For this reason, it is recommended that the printer be moved to another area if at all possible.
In addition, very smooth media types such as glossy; allow toner to more easily scatter about the page prior to becoming fused. Try using a less smooth media if at all possible.

It might be the driver for the Video card that is not installed properly. Go to Start then Settings then control panel then select the Systems icon Then go to the Hardware tab. Select the Device manager under display adapter you can click and see if the device is working properly. You can get the drivers from the motherboard manufactures website. Hope this helps. :]
