Color accuracy?
I've a Kodak DX6340, recently noticed that some colors are not
reproduced accurately. A deep blue/almost purple flower I was taking a close up of did not appear in the digital viewfinder to be the correct color, nor the finished image as displayed on my PC screen. It appears lighter than the real thing. I don't know if this is typical for this type of camera of if the sensor is aging? Camera is 4 yrs old and has been used quite a bit. Do the sensors degrade over time especially if exposed to bright sunlight? Thanks |

It's easy to imagine a camera having difficulty metering an exposure properly on something of that color, though. You might try a different metering mode or try bracketing. Don't expect center-weighted or spot metering to get it right. If you have manual exposure controls, try setting the exposure for stuff in the background. Ron |

Ron Ron, The only options for metering light are multi-pattern, center-weighted and spot metering. The camera was set to multi-pattern when I took the image of the flower. What is bracketing? Also, how would I set exposure "for stuff in the background", assuming this camera has that capability? Lastly, would it have made any difference in color accuracy, had I taken the picture in a setting other than "Close-Up Mode"? Thanks very much for your reply. Mike |

Mike Mike, Multi-pattern would be the best of those 3 choices. If you don't have manual exposure control, you might be stuck. Bracketing consists of taking additional exposures at settings like 1 f-stop higher and 1 f-stop lower to increase the chances of getting a good shot. Some cameras can do this automatically. If you can adjust EV (exposure value), that might also help. Close-Up Mode wouldn't likely affect the exposure. On the other hand, if you took the picture from farther away, metering might do better. You could crop the image later. Ron |

It also does (I think) have EV which lets you choose from -2 to +2. I'm not sure, but I think changing those values changes both f-stop and shutter speed automatically. What exactly do u mean by manual exposure control? Wouldn't that be a combination of f-stop, shutter speed and ISO settings? I can adjust all of those to some extent, but not for just the background of a close up shot. Thanks again for all your help. It's much appreciated. Mike |

Color accuracy?
Hi Fellows. new guy here - Harvey -I use a Panosonic Lumix FZ3 - a
fixed lense digital with lots of settings - I have started using the bracketing mod +1.5 - & -1.5 for most all of my "Specila" shots that along with photoshop seems to get most all I could ever want from my photos. I even recently shot the full moon and got my first decent shot. spot light metering mode spot focuseing -2 steps on light the camera took the photo at F2.8 at 1/25 Harvey in the California Sierras about 75 mi South of Lake Tahoe. |

Mike In manual control, you set the ISO, shutter speed, and aperture yourself, hopefully with the help of an internal or external light meter. Most non-SLR digital cameras don't have that capability. Sounds like you can change EV, so you might not need it. Ron |
