Noise problem? After taking a shot, previewing image in the LCd, see the light areas blink white and black repeatedly. checked my menu settings and can't find anything wrong. Do not notice anything abnormal in Photoshop

There is nothing wrong with your camera. What you are seeing are the blown-out highlights. Those are the portions of your image that have been overexposed so completely that they have lost all detail and will show up as pure white. In most cases the proper fix is to reduce exposure to bring back the detail.

If you simply don't want to see the "blinkies", press up/down on the multiselector repeatedly to cycle through the different views of your images.

It's possible that your Highlight Alert is enabled. Over-exposed areas of your image will blink to indicate blown-out whites. If you don't like this feature, go to the Menu, under the second blue tab (for playback), look for Highlight Alert and Disable it. When viewing the image on a computer, the blinking will not appear however. It's just to warn you that some parts of the image is so bright that all detail is lost. I enable mine so that I know this and is able to make adjustments on the ground.

It's normal.

The Nikon dSLRs have various LCD display modes, and one of them is called "highlight clipping warning display". Basically, when you set your LCD display to "highlight clipping warning display"(it's the mode right before the "histogram display"), it blinks white/black wherever your picture has blown highlights (i.e. where your picture is overexposed)

A histogram display is very helpful in telling whether you've got the exposure right, but to it isn't adequate by itself. With digital cameras, it's very important not to blow-out the highlights in a picture (they're similar to color positive film in that respect), since once you hit the maximum brightness, the image just saturates, and any highlight detail will be lost. A histogram display does a pretty good job of telling you how the image as a whole is doing, but what if there are just a few critical areas that you're worried about for the highlights? If only a small percentage of the total frame is involved, it won't account for many pixels. That means any peak at the "white" end of the histogram graph would be pretty small, and easy to miss (or just plain invisible). What to do? The folks at Nikon recognized this problem some time ago, and so have provided another special display mode on the D60 (as on most of their dSLRs) that they simply call "highlights," accessible via the Playback settings menu, under "Display Mode." This mode blinks any highlights that are saturated in any of the color channels. It does this by taking the nearly-white areas on the LCD and toggling them between white and black.

The problem is not with the LCD or the camera - You have got it set to ecomony / power save mode. Fixable through camera settings.

This camera is eleven years old, and is probably worn out

Hi!
This is a feature and not a defect of the K100D. You can turn this off by going to the menu and going into the second tab (playback menu). Once there, go to preview display, where you will have 3 options - off, histogram and brighten areas. Set this to off (your camera is set to brighten areas, that is why the white parts of your photos appear to be blinking).
Hope this helps!

it's tricky / annoying:

you have a preview ...
you have some of the (3) images checked
but also you have some of these images selected (blue outline)

now:
when you select (I don't mean the checking) an image you'll have to set the scanning params
again - or check them ...

if you select an image, and then set the params (like "color"), your scanned image will be in color

....
also resolution is the same way ..
especially after crating preview .. it'll be set to 300 Dpi
so after seecting one for scanning - check the resolution too :)

Hey marafioti14,
What you need to do is select shooting mode and then under that you need to select program mode, and under program menu you need to select the color mode which should allow you to set the camera to take black and white photographs. This being said I would suggest instead of shooting the images in black and white it would be better to convert them to black and white using computer software. It is likely that the software that came with the camera allows you to convert any image to black and white. I hope this helps!

Sincerely,
Allan
Go Ahead. Use Us.

Which mode are you shooting in?
You may have adjusted the exposure compensation so everything is washed out.

Whatever the cause, your images are overexposed. Try shooting in auto and the camera should take over the settings, but if you are in other modes, check your shutter speed, aperture, & ISO also. These are all things that can cause too much light and wash the picture out/OVEREXPOSE.

If you have any other questions or can give me more details, just ask!

Hope this helps!

Have you tried viewing the photos on a computer or printing them? There should also be parts of the menu/setting displays that would be white. The text on the image info should be in white.
If you are getting white, it would suggest your whitebalance isn't set correctly. If everything has a purple tint to it, check your LCD display settings, otherwise it may be the screen is failing.
