In camera noise reduction setting
Hi,
Lurked a while in this group. Lots of good info but I have a question that might seem obvious. My Olympus E-500 has a "noise reduction" setting that can be turned on or off. What is the downside of just leaving it on all the time? Thanks, Tom |

Thanks, Tom a) Not necessarily accurate to the amount of noise reduction you might want to do (sometimes more ISN'T better), and only uses its own algorithm, where after market noise reduction can be adjusted and can take many different forms. b) if it's anything like on the Canon, it requires the same amount of time to process as the original shot - so a 30 second exposure requires a full minute before another frame can be taken. -- You need only reflect that one of the best ways to get yourself a reputation as a dangerous citizen these days is to go about repeating the very phrases which our founding fathers used in the struggle for independence. -- Charles A.

What is the downside of just leaving it on all the time? It's probably a 'dark frame subtraction' type of noise reduction, where the camera takes a black-frame picture after you've taken yours. Then the dark frame is subtracted from the original frame to reduce noise. This is for longer exposures. It can be a good thing, or it can be annoying, depending on what you're trying to do. Note that if you're out shooting really long exposures at night or whatever, and you don't want to wait for the camera to take the second long exposure to subtract, you can do this: Turn off the noise reduction, take one dark exposure, and then shoot away. Later, you can use Photoshop (or equivalent) to subtract the dark frame from the others. This works best if you're shooting RAW. |

I'm a novice at Photoshop as well so I probably won't be using it in the way suggested right away. Sounds like it's not going to make much difference off or on for daytime shots but will improve night shots with the downside of a longer processing time. I move pretty slow at night so that's not really a downside for me. If I missed something, please correct. Thanks again, Tom |
