whats wrong with my camera?

[pontifex]

pic

i am using a Nikon D50

there are several dark spots on my pictures. doesn't matter what lens i use, they're always there in the same spot. they've been there for awhile. only noticeable on light backgrounds like clear sky as in the above pic.

doesn't appear to be anything on the mirror or the part above the mirror so i dunno whats wrong with it.

something might be on the CCD... can you take the lens off, set the camera to like... a 4sec exposure, and peer inside? Is the CCD even visible on digital cameras? Never tried that before, so who knows. I dont own a digital SLR so I can't say.

Clean your lense.

how thye hell do i do that?

Those are dust particles on your CCD. How to clean them off is a topic of fevered discussion on most camera forums. Probably the safest thing to do is get one of those squeeze blowers (DO NOT use a compressed air can), and try to blow them off.

This is the main problem with DSLRs (I am 20D owner myself).

he already stated its like that even when he uses different lenses. if they are in the same exact spot on any lens than its not the lens. he checked the mirrors inside too, so it shouldn't be those unless he didn't check them well enough.

Your camera should have a function to do a mirror lock-up. This locks the mirror up, uncovering the CCD behind it. The CCD is where the dust is, NOT on your mirror.

IT'S ON THE CCD (or CMOS) SENSOR BEHIND THE MIRROR!!!

the manual tells me how to do that but i don't see the option in my menu screens at all.

and you are yelling for the reason of? i was the first to state the possibility of particles on the CCD.

Okay... well if your manual isn't showing you how to enable the mirror lock-up correctly then I cann't help you.

Should have bought a Canon instead!! 😀

Actually, when I wrote this post I made no sounds at all.

And I wasn't writing in CAPS at you, I am trying to emphasize your point, and expand on it. It's not that he didn't "check the mirror well enough." There could be tar all over that mirror and it wouldn't show up in his actual photos, because the mirror moves up and out of the way, exposing the CCD/CMOS behind it, thereby recording a photograph. Any dust/tar/oprah winfrey on the mirror would just show up in the viewfinder, not in any photographs.

a very easy way to lock your mirror up is to either do a timed exposure of at least a few seconds, use Bulb, or use the Time setting. either will essentially allow you to hold the shutter open for as long as you wish, at the expense of battery life as the shutter my be held open using battery power.
with your lens off, when the mirror flips up and shutter opens you will see the CCD.

Hey np! 😉 I shouldn't have "yelled" either... I just get exicitable whenever DSLRs are being discussed.

 

[pontifex]

ok, i had to enable more detailed menu options to get to it...
did that and used an air blower on it. there was a small piece of dust there but i think there's another small piece that won't come off. the manual says not to use anything but air on the ccd.

will go out and take a fe test shots and see what its like now though.


edit: got it down to 2 specs instead of 5 now...will try some more air.

It's called dust. Get a rocketblower or whatever they are called. I'm not familiar because my Olympus cleans it's sensor 😉

EDIT: Here you go...

D50 does not have the MLU feature. But there should be a CCD cleaning feature that will pop the mirror up and open the shutter.
