The pic was taken during midnight , which was about 2 a.m. i guest. When i saw the pic on the camera LCD, i feel weird and i thought my LCD got problem. Later i view it on my pc and came out the same result. sad.gif

I just wish to know what had happened to my pic. Or my compact got problem.

Need some sifu to give opinion.

First off, what are your settings?

2ndly, your hands (I assume u didn't use a tripod) are shaky. The noise is very visible.

My first few moon pics looks like yours. =) Take time to tweak lo.

Yes, you are right , is a moon. I took it at the Kem Pacat near the peak of Gunung Nuang, Hulu Langat. My settings are:

shuttle speed= 2 sec
aperture= 2.7
focal length= 7.70
noice reduction= on

I am using a Sanyo VPC-AZ3EX compact.

I just want to know why the verticals lines appear.

THX.

Interesting... it could be something to do with your camera's sensor. Did you encounter vertical line problem with other night shots?

Yes, when the shutter speed becomes slower, the vertical lines become more visible and clearer.

I also found out that some daily shots also visible when observe it clearly.

What had happen actually? Is it my compact CCD problem?

its banding. nothing wrong with ur camera, except that you are pushing it to its limits (long exposure, low light, probably high ISO)

It's a CCD or circuitry problem.
Throw it back to the service centre if still under warranty and demand for a replacement. The worst that could happen is that they refuse to repair/replace it and tell you what some other forummers have told you: "you are pushing your camera to the limits, etc. etc."

To make your case stronger for a replacement, keep and show a few of the daytime shots to the service personnel so that they can't argue you're using your camera in "extremes not designed for".

My own encounter with the banding issue you can read here if you have the time:

I am not sure whether i pushes it to its limit or not because my compact have the slowest shuttle at 16sec. While i am just setting it at 2 sec only.

I find out that during some indoor scene(night) , vertical lines can be observe. While during daytime scene(with sunlight but in dark condition), vertical lines does not occur.

Is very weird, right?

This pic was shot during the time that is almost night(indoor). Vertical lines can be observe at those dark area.

The two pics in the post above that had the banding were in ISO400.
Can you try taking daylight pics with ISO400 sensitivity and see if the bands are there?
I don't even get this on my Canon Powershot A510 at ISO400, and on my sister's Powershot A540 at ISO800.

Most probably something related to high ISO electronic noise interference.
At any rate, do make it a point to visit the service centre.

I like the pic with the snails.

Thank You for liking the snails,

By the way, I have try some daylight pics with ISO400 sensitivity.

The results is that there are no banding effect but the noise is quite visible.

I own this compact for more than 2 years. The warranty has all gone. sad.gif

Maybe is time to buy a new one....... blush.gif

Here are some daylight pics with ISO400 sensitivity:

I've processed one of your photos to make the bands more obvious. It's much less noticeable in daylight shots, but that doesn't mean it's not there. It's usually hiding in the shadows. In fact, look at the satellite dish in the original photo more closely: looks familiar?
