    Hello guys,

    I was on vacation. I had the opportunity to go in a magnificent place in Greece (Edessa) with waterfalls. It was a good opportunity to try my OMD EM1 for long exposures.
    I used Oly 12-40 2,8, Tripod and Haida ND 10 stop filter.

    I disappointed from results. I attach some photos

    I've heard that there's the flaw in the em1, sort of a light leak may become visible with long exposures, as well as some noise issues but I'm not sure if this is it as I don't have an em1 to verify, it could be though.

    That mark seems odd. I've not had an issue with my Haida 10 stop and em1. I wonder if you got a bad filter. Are all your shots like this? I'm on my phone right now, so I can't check the exif...what mm were these shot at?

    That is some very nasty flare.
    Which lens?
    Was the sun just out of the photo each time?
    Did you have just the ND filter on the camera or another one as well?
    You could have shaded the sun with your hand to stop direct sunlight falling on the filter. Or a lens hood would have helped.

    I don't remember if each time the sun was just out of the photo
    Only the Nd filter i had.
    I couldn't fit lens hood with the nd filter.


    I was wondering if plays role that there was a space between filter and The holder of filter . The holder is a cheap from eBay. Something like this
    New Color Filter Wide-Angle Holder for Cokin P series eliminate vignetting

    i think you got something weird going on with your camera accessories

    i use the same body and lens combo, and often with B+W ND and/or CPL filter (and stock lens hood fits fine on top), shooting at all sorts of focal length and directions relative to the sun...never ever seen anything like that

    i do have 1 annoyance with the em1 for long exposure, and that is the sensor tends to overheat quickly(??), shooting series of long exposures is limited by necessary cool-down periods... and annoyance of needing to use NR-Reduction (via dark frame subtraction) lengthens time before review, and which further exascerbates the heat

    Pretty certain that full circle "flare" is not caused by a sun just out off the frame, to me it looks more like the reflection of your lens's front element on the ND filter being captured

    Now that sounds a good explanation. It would be caused by having the filter too far away from the front of the lens.

    Was going to say the same. How far is your filter from the front of your lens? If you have a gap and light's getting in around it, it's like shooting through a window.

    You might try throwing a dark cloth or something over the lens and filter to cut down on this. Careful to keep the edges out of the frame.

    First of all, those shots are very dull because of the time of day and the lighting conditions. A long exposure will not improve the quality of light. That aside, I assume you're talking about those reflections from your front element? The problem is your filter holder.

    When using square heavy NDs like a 10 stop, you need to make sure there are no light leaks between the filter and lens. It's fine to go bare for like a 3 stop grad but at 10 stops light leaks are a huge problem - they will reflect off the front element, off the back of the filter and dominate the image because so very little light from your scene gets through the heavy filter. Have a look at the stuff from Lee, they come with gaskets to plug light leaks between filter and lens. Personally I find them too much hassle, and use a circular 10 stop from Haida which mounts directly on the lens.

    Next time, try a long exposure in your back yard first to iron out these problems before you go on a trip.

    No, it is never a good opportunity to try something for the first time on your vacation.
    Apart from everything else, this is the best advise.

    The truth is that i didn't know about light leaks. I will search for a serious Filter Holder. I want to ask if the viewfinder must be covered when i took long exposures ???

    I realized this time. In my next trip i will be ready .......

    You are right. I will practice in order to iron out these problems...

    If there is anything else which i have to know for Landscape- Long exposures photos. Plz share with me...

    No, not with an evf.
    With and ovf, yes, but we don't have to worry about that ;)

    I'm new to long exposures too but I have learnt a lot from scouring YouTube videos about this. Lots of terribly long-winded stuff as well as too brief stuff too out there but you can still get a few tips and tricks here and there.

    Practice practice practice as they always say ;)
