What camera are you using it with? Do you get spots with other lenses? If you do are they in the same area in all of the images. If so you have most probably got dust on your sensor when changing lenses. With most DSLR cameras this can be fairly easily fixed with an Arctic Butterfly brush but they are not cheap and if you are not confident about using it then I would suggest taking the camera to a repair shop.
It can be a piece of sticky dust or dirt on sensor surface which can't be removed with a blower or canned air. You can try to remove it by yourself with special cleaning swab and cleaning liquid. But this process requires some experience, so the safer way is to bring camera to service center where sensor can be cleaned fast and risk free.
It's very unlikely to get hair inside the lense. You probably see the hair on the reflex mirror of your camera. Remove the lense, Check inside the camera body for any dirt, dust, hair etc. Take a blower-brush (you can get one from the nearest camera dealer) and gently blow-brush away any particles from the mirror and the cavity. DO NOT use any force and don't touch the curtain shutter as it can easily be damaged. Don't touch the insides of the camera with your fingers, since the grease from the fingertips attract dust. Replace the lense. The hair should be gone now.
Dark spots are usually the result of dust or dirt on the lens. If a simple soft bristle brush (1/8" wide paint brush is ideal) can't dislodge the debris, you should purchase a lens cleaning kit available from camera stores. They run about $10. These are great to removing these and other contaminants such as finger prints, smudges, etc. High end lenses have special optical coatings and the special cleaning fluid included won't leave a residue - or damage the coatings.
If the spots are bright or colored, (or dark after cleaning above) the electronic sensor inside the camera has a "hot" or "stuck" pixel. This problem is usually not worth fixing due to cost.
Not really. Most cameras, including the P90, are designed not to show images not captured on that device (or at least the same model device). If it's a paper map, you could always try to photograph it. Photographing something off a computer screen is a little harder.
The spots are dust on your sensor. You can clean these yourself but you must learn the techniques first. Google the words...cleaning a DSLR sensor. You will be taken to sites which will explain in detail how to do it and what supplies you will need. It may seem daunting at first, but it is really easy once you know how.
Is your camera an SLR, if so then your mirror might be at the wrong angle, if that is the case then you need to have a specialist tilt the mirror, if your camera is not a SLR then this is a common problem when taking pictures from a short distance away from your subject, as the view finder is above the lense so what appears centered in the view inder will be much higher up in the lense, there are two ways to fix this, one is to use the LCD, or most cameras have correction marks in the view finder,and these show where the actual edges of what the lense sees are, use the correction marks.
D-SLR cameras are designed to be used with interchangeable lenses
and foreign matter may enter the camera when lenses are changed. Once
inside the camera, this foreign matter may adhere to the sensor, where
it may appear in photographs taken under certain conditions. To prevent foreign matter from entering the camera
do not change lenses in dusty environments
point the camera down when changing lenses.
To protect the camera when no lens is in place be sure to thread on
the body cap provided with the camera, being careful to first remove
all dust and other foreign matter that may be adhering to the body cap. Remove foreign matter from low-pass filter
Clean the low-pass filter covering the sensor as instructed in the camera manual or continue reading below.
The Nikon D300 and D60 has the ability to clean the sensor* using
the "Clean Image Sensor" feature. Please see page 371 in your D300
User's Manual, and page160 in your D60 User's Manual for more
information. *Clean Image Sensor may not remove all sensor
contamination and additional manual cleaning may be necessary. See page
374 in the D300 manual, and page 162 in the D60 manual for more
Fix images with black spots
Photographs with dust or foreign matter on the low-pass
filter can be retouched using the 'Image Dust Off' function available
in Nikon Capture 4 or later (available separately) if the image was
taken in the NEF format, for more information visit the article on 'How does Image Dust off' work.
CCD sensor has some dirt/dust on it . Set camera to B ( in manual mode scroll until 'bulb' is displayed in the top display ) . Take lens off and release the shutter and keep the button pressed down so that the sensor is exposed : use blower to remove dust/dirt but NB do not touch sensor surface as you will make it even dirtier. Take some shots to see if the spot has gone and repeat if it has not disapear.
