Re: Viewfinder Obstruction

If the dust/dirt is visible in the finder, it is in one of three locations: - if very sharp, it is on the "grind" side of the viewing screen, which, unfortunately for cleaning ease [unless the screen is user-removeable], is often the upper side of the screen in newer cameras. - if fairly sharp, it is on the non-"grind" side of the screen, and it may be possible to remove it with a VERY soft (very clean!) small brush or a VERY gentle blowing with a hand syringe-type blower (blowing hard into a VF area just about guarantees that dust will be blown in). - if very soft-looking, it is on the underside surface of the pentaprism (being able to clean the VF area without a repair is an excellent arguement for having the interchangeable-screen feature...). Prevention is the best way - never leave the body cavity uncovered (except briefly, when changing lenses); never change lenses in a windy area; keep the rear area of the lens clean; get in the habit of facing the open camera downward while changing lenses; NEVER blow into the body cavity (unless you know what you are doing, the mirror is up, or the screen is removeable). Hope This Helps

Spot on viewfinder and picture


Whoops! Clicked the wrong icon before. Here's my solution:

The spot is most likely a spec of dust that is on or in the cameras' lens or optical sensor (the sensor is the "film" in digital cameras). Dust is a problem for the SLR type cameras (the kind that have removable lenses) as the camera body is open when swapping lenses. Your camera does not have the ability to accept different lenses - so the chances of dust is minimized - but not impossible. When zooming, the lens extends and creates suction inside. When air is drawn in, a particle of dust was could have been brought in at the same time. Most of the time, dust will vary in appearance from a sharp, irregular shaped object to a fuzzy, rounder object - depending on whether the lens is zoomed in or zoomed out. A professional cleaning should be able clear this problem. Contact a camera shop for an estimate.

Other times, this is a much more sinister issue. The optical sensor has developed a problem. The optical sensor or simply "sensor", is a small rectangular semi-conductor that is sensitive to light. The size is often stated in "pixels". The are about 10 million pixels on a 10 megapixel camera's sensor. One of the sensor's has stopped responding to light focused on it by the lens. Depending on how it failed, this will appear either as a sharp, black dot in the same place of every picture if is failed "off" (this is called a dead pixel), or as a sharp colored dot in the same place of every picture if it failed "on" (this is called a hot pixel). Unfortunately, dead and hot pixels can not be fixed individually. The entire sensor must be replaced as a unit. This can be a costly repair depending on the camera make and model and sometimes it is better to buy new instead of investing money in an older camera. Again, consulting with a camera shop that does repairs or even the manufacturer in this case is in order for the best estimate of what repairs may cost. Good luck!

When i open my camera to take a picture all i get is a black view. i cannot see anything on the display or through the view finder.


Does your camera also have an optical viewfinder? If so, chances are that you accidentally pressed the button that turns the screen off to save battery power. You would then use the optical viewfinder in its place. For your model camera, read the user manual to find out where this button is. On Canon cameras, it's usually a little button labeled DISP or DISPLAY. Just press it oonce to turn the screen back on again.
But if the above doesn't help, have you tried downloading photos taken when the screen is black? Are these photos also black? If so, chances are in this case that you are experiencing a stuck shutter. This is also very easy to remedy (see this).

The screen of the viewfinder has a black dot.. i tried to clean it but it cant be removed,..how can i removed it?


Remove the lens of your camera, do it in a clean room, look at the mirror insie the lens to see if the dot is not there rather that on the outside of your viewfinder.
If it is not there it might be on the inside part of the focusing screen. Still inside the camera look at the upper part of the body, the focusing screen looks opaque.

If you still cant find the dot it might be on the inner side of the focusing screen.
Here is a tutorial on how to remove it on a d70 it is essentially the same thing on your camera.
Otherwise it can also be on the inner part of the viewfinder. In this case I recommend to send the camera to a repair shop as the removing of the viewfinder seems to be more difficult on the d3000 than on other camera.

Hope this helps.

There is some black unremovable dots (not visible on sensor sirface). Is IMAGE DUST OFF REFERENCE DATA helpful to remove that black dust like dot from image? how can I use that feture?


Black, unremovable dots are probably bad pixels in the sensor. These are parts of the sensor that no longer react to light. If you don't see any issue looking through the viewfinder, then the sensor is messed up. Since you say you don't see anything on the surface, I assume the optical part of the camera is in tact. You can try cleaning the sensor - Menu - Setup - Clean Image Sensor - it certainly can't hurt.

Sony DSC-V1 optical viewfinder has a horizontal line in it


It shouldn't be there, but as the optical viewfinder is completely separate from the photographic light path it's nothing to worry about either.

Normally it's caused by either a hair or fibre which has somehow entered the viewfinder (rare) or more commonly by a fine scratch across the front window to the viewfinder. Also check the rear viewfinder viewing lens as the same damage could occur there but as that lens is relatively protected it's unlikely.

Any further fixing involves dismantling the DSC-V1 and possibly sourcing spares made of purest unobtanium so if the camera works perfectly well then leave the screwdrivers safely in the toolbox for now.

View finder focus


Is there a little black wheel or anything beside the optical viewfinder that turns? If there is, turn it until the image comes into focus.
