Nikon D80 - Problem with ISO HI??

[mynameisjizeng]

Hi all!

I'm in desperate need of help!!

I acquired my D80 about a month plus back and it's been working perfectly. However, when I switch to ISO HI to shoot lowlight conditions, I notice that the top margin of every picture tends to be "bright" i.e. there seems to be a very faded white band at the top.

I've checked, and can definitely confirm that it's not a result of flare.

Any comments? Is this usual?


Thanks!

Maybe a attaching a picture will help us understand more on what you mean by the white band.

do cap the the iso at 800 unless you really can stand image noise at iso 1600 or 3200.
i don't even switch to auto iso when shooting in low light conditions.

D80 does not like anything above ISO 800. pictures help!

noise above iso800 for D80 is considerably high and is known.

anyway, picture tells a thousand, do attach one if want qualty feedback.

Noise control is bad enough even at ISO 800 + High ISO NR (Normal). The noise at higher ISOs are much worse from past experiences. Try not to use ISO HI 0.3, 0.7, 1.0 unless you really need to. Try to go at most 800 or 1000. Worse come to worse ISO 1250 and 1600. I almost never exceed ISO 1600. Picture quality deteriorates a lot the higher the ISO number.

for myself i'm not prefer iso higher than 400 on d80
a little bit over exposure can help reduce the noise

Most of the times i assume that one is in need of more exposure and hence pushed to up the ISO, and would be difficult to already overexpose ( handheld ) to reduce the noise.

hey guys,

thanks all for the prompt response! i've been having trouble getting on to clubsnap - not v sure why. i'll upload the sample photos asap.

i normally don't use anything lower than iso 1600, but used it on HI recently due to night shots (didn't have a tripod with me)

thanks!

hi just to share my exp with d80 on iso above 400 , try not use d80 above iso 400 but if u die die must go above 400 try use a slower SD card wat i mean slow is any card below ultra & extreme for sandisk , dun ask me why , base on my exp over the year with d80 it help me on less noise on iso above iso 400 , do take note it less noise not no noise , have told few of my shooting mate with d80 and it work for them too so for d80 fast card is not always better , hope it help

thats a very interesting theory u have. ever tried doing some image comparisons with fast and slow cards?

The information captured by the camera before transferring to a fast card or a slow card is the same. Would be useful if you got examples to compare between the two, would be really interesting if they are really different

With judicious use of noise reduction post production it can be controlled a little
Here is a shot I took at ISO 1000 with a 50mm wide open in Cambodia. Any higher ISO in dim lighting I find it abit more difficult to smoothen the grain without loss of sharpness.

Does it look like an "amp noise" problem?
