CCD problems?

[henryberkins]

hello

 

just posted a question this afternoon, and then went out and shot the sunset

with my hassie.

 

took my D50 along for the ride and as a lightmeter, but now im getting the

shots from the D50 onto my computer and they seem to be noisy, and have low

line definition.(look pixely) i was shooting ISO 200 RAW+jpg basic and im not

happy with these results at all. especially after all the great shots ive had

with my D50.

 

could there be a problem with my CCD? i certainly hope not, seeing as this

might cost me a small fortune to fix, might as well buy a new camera. \

 

im using a horrible lens(nikkor 28-80mm f/3.5-5.6 and that might be some of

it, i was shooting from a tripod with my remote release focussing on infinity

most of the time. the photos still werent sharp, might be in part due to the

lens)

 

any ideas? this is getting to be a real problem.

 

thanks in advance

Since you're shooting digital, why not post the pic here so we can see it? It would help to give you a good answer without guessing at the problem.

here, might be nothing wrong, but if there isnt, im going film(mind the dust, cant afford to have it cleaned)

Aside from the ISO how long was your exposure?

Long exposures can cause "grainy" photos.

[jautey]

I can guess from the birds in the photo it wasn't that long.

Upon closer examination, it looks to simply a case of underexposure.

But not by much, a couple of stops.

No big deal.

What did you use to convert the RAW file?

 

Your EXIF data says you had exposure compensation set to -1 stop. My guess is your RAW converter has some automatic settings that tried to bring up the exposure thus the resulting noise.

[henryberkins]

i shot RAW + jpg basic, i didnt convert, you guys got the jpg basic file. i did underexpose 1 stop and long exposure NR is on. but shooting ISO 200 noise shouldnt be a problem in the first place should it?

Underexposure = noise.

 

You can clean your own sensor very easily.

agreed... ISO 100 underexposed 2 stops will have more noise than ISO 400 exposed correctly, especially in a lower light situation.

The meter may have been fooled by the bright sky into underexposing even more. The histogram does look like serious underexposure - and a simple levels adjustment on the highlight side improves the image quite a bit.

28-80 is a horrible lens. Dunno why Nikon even bothers to sell it from their small repertoire of lenses!

 

What didcha meter? I always meter a medium ground and lock the exposure. Works alright.
