Hey cj17,
Since this spot is both on your lcd and your pictures the lcd is most likely not to blame. This spot is probably caused either by dirt on the lens or the sensor, or it could be caused by a dead pixels on the sensor. You can try cleaning the lens, and if this doesn't work you should have it looked at by an authorized service technician.

Sincerely,
Allan

Tiny black spot lcd


Erika, Do you mean you have a black spot on the LCD of your camera?
We call that a dead pixel. Can be black and can be white. Most LCD's sooner or later have a one or more dead pixel(s). As long as they are not in the centre of the screen you won't notice them. Even dead pixels on the camera sensor can happen. These you won't see at all, because the software does calculate what that pixel would look like in that specific shot. And the software will place a correct colour on that spot.
Try to live with the dead pixel(s). you won't see them on the actual pictures. Not on the computer to tablet and not on a print.

If the spot is in all foto's and in a video, it is most likely not the lens. Could be a dead pixel (some pixels). But almost certain a spec of dust or othes debris that entered the camera.
Because this camera came with a fixed zoom lens, there is no sensor cleaning option. And I can't find a posibility to make a dust retentie picture.
To check if the spot is on the sensor, put the camera in manual, set aperatur to the greatest figure (smallest opening) an make a picture of a white object. If you see the spot, you were spot on. When the camera is new, this could be a reason, to go to your dealer and ask a new camera. Take the dust retentie picture with you.

Recently I found one balck spot on my picture, I dont know whay the black spot is coming. I am having a Nikkon D90 18-105 lens.


The black spot can be from one or two sources. The first, is a called a stuck or hot pixel. Your camera's sensor has 12.9 million pixels (12.3 million are used for the image). Many times, a hot or stuck pixel is a bright color - red, yellow, green, etc. It can be any color however. Dark or black pixels can also be called dead pixels as they look like they're "off." Regardless of which your camera suffers, it will not respond to light projected on the sensor by the lens. You'll have to have manually edit the pixel in each image, or return to Nikon for sensor replacement. Nikon used to perform a mapping out of the pixel, but it seems that they don't do this any longer. A sensor replacement can cost in the hundreds of dollars.

The second source, is dust on the sensor. A pixel(s) blocked by dust will show up in each picture, but will appear to be more in focus in some images than others - depending on the aperture value of the camera when the exposure was made. A stuck pixel usually has a very definite edge on all images regardless of aperture setting. A simple, careful wet cleaning of the sensor with a product designed specifically for the job can solve this problem pretty quickly.

Here's a video for wet sensor cleaning from Youtube There are others here too. I hope this was helpful & good luck!

When ever there is a picture taken there is a flicker when i view the picture in my camera it happens only on the bright spots ...ehy is it


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.

Black spots on LCD screen

Black dot on my screen about the size of an unsharpened pencil's point. My camera is Olympus 790. The dot id on the pictures when printed and the screen.


The solution you can try is to run a function of the camera called Pixel Mapping to see if this removes the dot as it will redistribute the pixels of the camera on the LCD screen. To access this function - have the camera in shooting mode - go to Menu - right arrow to setup and press Ok - down arrow to pixel mapping and right arrow over to highlight start and press ok. The camera will try to repair itself. If after running this the dot is still there then you may need to send the camera to Olympus for service as the image processing chip may need to be replaced. http://olympusamerica.com/cpg_section/cpg_servicerepair.asp

Pentax Optio s50 The LCD display has lost some pixels and now has a circle of black spots on the screen. Is there anyway to fix this or is it time for a new camera? I can't just look through the view...


If pictures taken in Auto mode look the same on a computer (or when printed) as on the LCD display a Sensor fault is indicated. If the Computer image is OK the LCD display on the camera is faulty.
Assuming your camera is out of guarantee you could request a quote for repair but beware the "Minimum Charge" some suppliers impose just to tell you how much it will cost.

Canon 350D photos have a small red dot on them


if the red spot is always on the same place in each picture.... seems like a problem with the sensor ...

The sensor uses three channels to create colour... RED / GREEN / BLUE... one of the pixels for one of the sensors is gone

Lens cap test...


Switch on camera into Shutter mode. Put lenscap over lens or block it so you get a black LCD. Have a look at that first. Only a general indication but if there ARE any bad pixels on the LCD they will be visible as coloured dots. Not too important as THAT doesn't affect the pic but personally I would not put up with it - took one back for exchange for that reason .. who wants to look at spots. The CCD is the real one to look for. With lens still blanked off to a black screen set the shutter at 2 secs, take a pic then set at 4 secs, take another pic. You won't see much on the LCD so you should download those tests to your editior - Paintshop Pro, Photoshop or whatever. THEN you get a much bigger pic (black) to look at. You'll probably find at least one or two little spots, almost inevitable with many, but you should NOT get many and also very noticeably bad spots. If so , complain and exchange.
