QUOTE(Rithrade @ Jun 24 2007, 04:49 PM) First off, what are your settings? 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: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.  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. |

QUOTE(chua @ Jun 24 2007, 08:48 PM) 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? |

QUOTE(BurgaFlippinMan @ Jun 24 2007, 09:39 PM) its banding. nothing wrong with ur camera, except that you are pushing it to its limits (long exposure, low light, probably high ISO) 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. QUOTE(cjtune @ Jun 25 2007, 01:43 AM) It's a CCD or circuitry problem. 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.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: http://forums.clubsnap.org/showthread.php?t=224562 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.  At the sme day, this pic was shot at out door. Verticals line can be clearly observe.  This pic was shot at daytime(dark condition) but there are no vertical lines occur.  |

QUOTE(cjtune @ Jun 26 2007, 12:00 AM) The two pics in the post above that had the banding were in ISO400. Thank You for liking the snails,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. 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. Maybe is time to buy a new one.......  Here are some daylight pics with ISO400 sensitivity:     |

QUOTE(any1else87 @ Jun 29 2007, 03:06 PM) wat camera u are using? I am currently using Sanyo VPC-AZ3EX compact with max 8.0 MP.QUOTE(cjtune @ Jun 28 2007, 10:56 PM) 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? Is it time to buy a new cam or go for repairing? If is time to buy a new cam, should i start with a prosumer or dSLR? If want to repair, which shop to go?By the way, thank you , cjtune. Thanks for helping me to get answers for my question. |

QUOTE(cjtune @ Jun 29 2007, 11:13 PM) Most probably not worth repairing but why not ask to see how much it'll cost you? How high is the ISO that can let bands to occur? No matter what type or model of camera you're buying, please test it out before buying by doing a number of high ISO shots underexposed or in a dark setting. If you candidate camera can have it's EV adjusted (either has shutter or aperture priority mode, or fully manual mode) to about -1, -2 EV and see if you can spot any bands. Both of my S$2000 E-330 and S$1350 E-510 has bands at high ISO too and I am disappointed with Olympus for this. But at least there are a lot more other features in them to enjoy. My compact has a highest ISO at 400 and you know, bands occur. |
