10D long exposure noise like this---------->

Go to last post
Black frame subtraction method used by the D30 and S30 . 100% clean pics! if Canon had the sense to combine the low noise system in the D60 with blackframe - the 10D images would be the best for long exposures as the few stray pixels there are would be gone..

As an option rather than being forced to, that would be ideal. But I'd be more than happy if the 10d merely had the SAME long exposure quality that the D60 does... but judging by those three sample pics, it is a LONG way off being as good.

Something has to be wrong with the last two pics ...256&..258????? Am I seeing things???

I agree something has to be wrong. What is with those consistent specks? The first photo looks great though.

Maybe if they'd be combined yes... But a 30s exposure on a D30 looks like ISO1600!
 
I've not tried it on a D30, I'd have expected it to be at least as good as on an S30 which is totally clean and noise free

S30 at max time - Maybe 8 secs, can't remember but it was at it's maximum time

...from other cameras. I just think this one slipped past the pixel-mapping stage at the factory. Probably the last thing done to each body before it is PUT IN ITS BOX with its documentation. (Maurice didn't get box and docs)

Hey, before any of you flame me, look at the pictures by Maurice
and tell me what you think?
my D60 does better than this by far..........(and be sure to look
at the original sized)

The first one looks way cleaner than the much shorter 30 second exposures I got out of my D60. I found that anything more than 30 seconds with my D60 was basically worthless. The second and third really look bad, but I don't ever expect to shoot exposures that long.

You're kidding me right?

I took this last night at 60s and would say the camera is far from worthless at > 30s. About 3mins and yeah, it starts crudding up.

yes yes photo 1 is pretty good but for some reason (twice the exposure time?) photos 2 and 3 are beyond awful. totally "peppered" with hot pixels.

LOOK AT PHOTOS 2 and 3.

Hot pixels are a fact of life for digital cameras. Otherwise, the
photo does look very clean.

FYI, they do this in the 1Ds. By default you get the ongoing chip noise reduction - similar to the D60 - and you can optionally turn on the black frame subtraction.

george, if your d60 does not produce beautiful, clean images at only 30s exposure time (ISO 100) then you have a dud. send it back!

my d60 was great up until about, say 4 minutes or so. screw black frame subtraction (doubles processing time), canon's "active pixel" i think they call it system is fantastic- stunning virtually realtime noise reduction.

i dont think the 10D will be this bad, i think this is a one off.

i was gonna type something witty here but then i changed my mind.
 
Perhaps my statement was not entirely accurate, I've had very clean 30 second exposures at ISO 100, but far less stellar results at progessively higher ISOs, so I'm sorry that in a sense I was comparing apples with oranges. My real hope is that the 10D will produce improved 30 second to one minute exposures at ISO 400 and 800.

fair enough. dont get your hopes up though... i'd keep the ISO as low as possible for long shots, say ISO 200 max.

keep in mind that a 30s ISO 400 is like ISO 100 for 120s (2 minutes).

similarly 30s @ ISO 800 = 4 minutes @ ISO 100

but even so i would expect the lower ISO shots, at respectively longer times, to be much cleaner.

Yes, don't ignore the nice 127 second outdoor image (1st of 3) Maurice posted. It shows it IS possible to get a crisp, non-speckled long exposure out of the 10D. Perhaps his particular camera is temperature sensitive.
