    Anyone using 10 stop filters or welding glass for long exposure photography with m 4/3?
    Seen some fantastic results and would like to give it a go.

    What are you using, I've seen some cheap 52mm 10 stoppers on Amazon which would fit my 9-18. Anyone got any recommendations or tips?

    I've used welding glass with medium format black and white film. The stuff I got was very cheap replacement glasses, green, and around 14 stops density. I tried the glass on an e30, but ran into exposure times not going long enough, and under exposing. I tried upping the ISO, but you have to like noise doing that.

    I'd go for a known neutral density filter - no strong colour cast, and with the welding glass I noticed loads of optical imperfections, although I noticed none in prints. 14 stops with the film I used gave me round about 20mins @f11 in full sun. Some things looked good, and some not so good!

    Have fun

    Wow.....20 minute exposures. Far out! I've been looking at the cheapo variable ND filters myself. Anyone have experience with those?

    I've read that the cheap variable ND filters can make images look soft.

    I went with a Cokin P filter holder (with step up rings) and a selection of P-sized ND filters.

    If you just want to experiment for fun, the cheap stuff may suffice, but if you want to achieve quality images, I would advise getting a Hoya 10 stop filter. As others have stated, the cheap stuff will give you a strange color cast.

    I recently came across this fantastic article on using neutral density filters, and it is very much worth a read: "The Ultimate Easy Guide To Neutral Density Filters" by Peter Hill | RedBubble

    The images found on this site alone will get you excited about the possibilities. I'm going to dust off my DSLR and filter kit to explore beyond the occasional waterfall shots.

    For people in the UK, i have a 7dayshop.com Variable ND Filter. I got it mainly for video, but you can get some great photos with it too. I think mine was £19. Well worth a try in my opinion.
