    Help E3 Noise

    Hi All

    I'm using a friend's E3 and finding it very difficult to do any night photography without getting a lot of noise.
    yes noise reductions seem to work ok but doesn't help when doing startrail where you can't have the processing time,
    even at 100 iso f2.8 20sec very noisy (12-60 f2.8 lens).

    Am i doing something wrong or is there some tests you guys can recommend?

    best advice is to post an image so people can see what the problem is, having said that I switched brands from Olympus due to noise, mine was a E300, I'd hoped that they 'd resolved the noise issue before the E3 came out

    Thanks dbax,
    and Voila!!!!

    This was 15sec f2.8 100iso 12mm straight out of camera resized only.

    btw dbax, the fact you changed away from Olympus does not build my confidence that i can resolve the noise issue in my friends E3!!!!!

    ahh this brings back memories or should I say nightmares, I resolved my noise issues for a while using noise reduction software(Noiseware in my case, but there are many others). It seems to be something thats an Olympus problem. I don't know if its too many "pixels" crammed into that sensor or what, but it obviously is an on going issue. I really thought they'd addressed it.
    Any way if you don't mind I've run the supplied image through Noiseware 3 times on the default night exposure setting just so you can see the effect it has.
    It kept me going for a time but eventually frustration got me and I jumped ship. no noise issues now
    I've put them side by side, can you tell the difference

    Thanks for that, the worked image does look good, and i would think at 2000+ iso it would be fair enough.
    The idea here was to go do startrails with taking 100 or so images and staking them.
    I also noticed that the noise got worst by the end of only bout 30 images, as if it was sensor heat as well, but i'm not knowledgeable enough to know.

    Ok stacking, usually if you take images to stack you need also to take what they call "darks", that is exposures with the same camera settings in the same environment(read same outing) with the lens cap on. These put into the stack and run through a stacking program like startrails(http://www.startrails.de/html/software.html) this will take the Darks into acount and can remove light fog to a certain extent.
    I don't know that it will help with the noise because you should still get that with your dark exposures.
    Don't know if you have the program, its a freebie, and worth investigating if this is what you want to do.

    Yes i do have have that program, i've actually had a little bit of a go at startrails with my own camera (D300), with some success.
    But next time i do it, i'll take your advise onboard, thank you.

    That's when we really realised that there was a lot of noise in my mates E3 and couldn't resolve it,
    hens the cry help as it is a beautiful camera to use.

    I also notice that during the 15sec exposures there was a "werring" type sound, is that normal?

    can't help with the "werring"noise,sorry.
    If your interested in astrphotography we have a member who's right into it. He has his own web site http://www.asignobservatory.com/. check out some of his posts on AP in the night/astro section many are full of useful info and tips.

    perhaps some current Oly users might be along later with more advice about the sensor noise.
    Nice chatting with you

    However, the E3 is not a new model, it's a few years old now. There's been talk of a successor, but that's not going to help you right now lol.

    I was referred to this site not long ago, you may find some useful info on there about the best settings noise wise.
    Olympus bodies: E330 & the E3. Lenses: Zuiko 12-60mm, 50-200mm. Sigma 105mm. Extras: EX25, FL36R, FL50R and a few odds and ends

    Lol, my brains are pretty useless, I'm still getting acquainted with mine too having only purchased it a scant few months ago. Perhaps some day in the future we can swap notes! You may learn faster than me!

    We'd like to see how another E3 handles the same situations side by side.
    I'm wondering at the moment if there is something wrong with his E3.

    I'm curious about what the exposure is in the photo above? Just had a quick play around with 15sec exposures on same camera & lens (indoors though)... some noise is there but not at the level above.

    Actually I've just reviewed some old night sky shots with the E510, one had a 60sec exposure, no where near this much noise. I dare say it's a setting in the camera or something's wrong for it to be this bad.

    That's why we would like to see another E3 side by side.
    Because if it's a setting somewhere, we are failing to work it out.
    The above photo was taken at 15sec, 100iso, f2.8, center weighed
    no flash, no nr, focused to ifinity.

    I can put up the exit data if that helps, for some reason photobucket seems to have stripped it.

    ps if you are going to replicate the situation, this shot was about the 40th shot in a continuous group. As in i kept taking a the next shot (using the IF remote) 1 second after the previous.
