The camera needs a professional service. If you're lucky the fault is just due to gummed-up, dried-out, lubricant films but if luck is against you you'll need a new shutter assembly (highly likely). Spare shutter assemblies are not easy yo come by, so if the repairer tells you that the shutter is broken you may be better to look for another camera.

35mm SLR's are mostly worthless or nearly so these days except for a few professional grade models, so getting a replacement is not difficult if you're prepared to accept different makes/models.

My flash is not working its either to bright or black


Look.. go to menu , find flash option .. enter it.. go for TTL option in flash . If you are trying to do manual settings then you have to understand flash power before every shot. TTL mode will automatically decide the flash settings for you.

Every camera has a flash sink speed.. above which it will not work.. and you will have either black bands on the image or full black . So shutter speed should be maximum 1/200 or 1/250 (which ever is your sink speed) . Check the manual ..

Another option for malfunctioning flash can be due to improper opening of the popup flash head. Many a times if the spring used in the flash gets weak and cannot lift up the flash completely. So the flash won't trigger and you will have an under exposure or black photographs.

Too much bright flash can be also due to the circuit problem , but this is very rare and can be rectified by a service center only.

Check if any of the above guidelines can help you and inform.

I am using a Nikon D200. When using flash I can't raise the shutter speed any higher than 1/250. It seems to be locked there and I don't know how unlock it. Please help.


That's entirely correct. 1/250th is the fastest shutter speed you can use when using flash. Many other cameras can still only use 1/60th or 1/125. It's all to do with the two curtain nature of an SLR shutter: when you release the shutter, one curtain withdraws across the frame to expose and then a second one follows behind to shut off the light source. For exposures of 1/250 or slower on your camera, the second curtain does not start to travel across until the first one has fully opened, so you have a fully open exposure frame allowing the flash to reach every part of the sensor. At faster speeds, the second curtain sets off before the first one has finished and at the highest speeds it's so close behind the first that only a narrow **** is open to the incoming light as the shutter curtains pass across the sensor. If you fire the flash at these speeds the shadow of the first or second (or both) curtains will appear on the sensor and the picture will look like a narrow horizontal band, or if using fill in flash, it will look like a bright band across the picture.

It's immaterial though as the normal exposure rules don't apply with flash: the flash duration is typically anywhere from 1/4000th to 1/50000th and in that exposure time it outputs sufficient light onto the subject to enable a photo to be captured. As the flash is the dominant light source, the ambient light captured when the shutter is open for 1/250th is insignificant unless you're making a daylight exposure and using the flash for fill in purposes.

There are some specialist SLR and flash combos which will allow the full range of shutter speeds, but they do so by firing the flash multiple times very rapidly to ensure that there is flash light present effectively continuously as the narrow exposure **** passes across the sensor.

Compact cameras have shutters which work differently and which fully expose the sensor at all shutter speeds, so in that respect they can have a far more flexible flash exposure system. Unfortunately, they ruin it by having pathetically weak built-in flashes which are only good for very short distances.

Nikon D90 rear curtain sync will shoot flash twice


That is most likely the TTL preflash and should not show up in your final exposure.

Try setting the flash control to manual (e2 under the Bracketing/Flash menu). That should give you only the one flash at the end.

Problem with print


It sounds like your shutter may be failing.

The N80 has a vertical travel focal plane shutter. This is essentially two curtains that travel across the film plane. At lower shutter speeds, one curtain opens up the shurter, you wait, then the next one travels across, stopping the exposure. At faster speeds, though, they both move together, leaving a small gap between them to let light through.

If the first shutter curtain isn't always making it all the way to the top, this could give you just what you're seeing -- a black band across the top of the photo. One blank negative may well indicate that your shutter failed completely on that shot.

This is something best handled by a camera repair shop. It could possibly just be some dirt in the shutter mechanism, which would be fixed by a good CLA (clean, lube, adjust) ... that's no a bad idea if it's an older camera anyway. However, it could be more than that. It won't be clear which without getting down into the camera itself.

All photos underexposed, changing settings does not help


defective shutter curtain opening, it needs pro service. Shutters have life expectancy around 5thou to 10 thou shots.
