p.1 #1 · p.1 #1 · Olympus OMD EM-5 Long Exposure File Write


Hi everyone,

I've been toying with long exposures on my Olympus E-M5, and it's been a particularly frustrating experience because, afterward after a long exposure, the camera spends an equal amount of time writing the file to the card. I.E., if I take a 2 minute exposure, the camera will afterwards spend another 2 minutes writing the file to the card.

I searched through the manual for some setting to change but came up with nothing.

Is there a way around this?

Philip

It's the long exposure noise reduction. Most cameras have it now. It takes a black frame with the shutter closed of the same time and subtracts the base long exposure noise and hot pixels from your image. There's a setting to turn it off, though your images will be a bit noisier.

Page 89 in the manual

Noise Reduct.

This function reduces the noise that is generated during
long exposures.
[Auto]: Noise reduction is only performed at slow shutter
speeds.
[On]: Noise reduction is performed with every shot.
[Off]: Noise reduction off.
• Noise reduction requires about twice the time needed to
record the image.
• Noise reduction turns off automatically during sequential
shooting.
• This function may not work effectively with some shooting
conditions or subjects.

Ah, my problem was that I searched for Long Exposure Noise Reduction, and not Noise Reduction itself.

Thanks for the help.
