@MK: Thanks MK!

@sara: Thanks sara!

@Richard: Thanks Richard....these long exposure shots are actually quite easy to do but you need a tripod and a some specialist neutral density filters. For this shot I used two filters - a 10 stop nd filter and a 6 stop. Combined one on top of the other and screwed onto the front of the lens they give 16 stops of light reduction which allows long exposures to be taken even in bright sunlight.

At dusk and dawn you'll get the same effect with a much less radical nd filter, and at night of course you don't need any filter.

This shot here http://ianbramham.aminus3.com/image/2009-02-18.html for example needed a 10 minute exposure but didn't use any filters but it was so dark I could hardly see those rocks in the foreground.

@Anna.C: Thanks Anna.....I'm sure you know by now that Michael Kenna is my favourite photographer!

@Ian Smith: Thanks Ian!

@Scene by Sharon Photography: Thanks Sharon....if you are interested there's a couple of small articles here that I wrote when I was still using my Nikon D40 which go into the long exposure technique in more detail: http://www.ianbramham.com/section255881.html The basics you'll need if you want to try daytime long exposures are a 10 stop neutral density filter (but I often use a 10 and a 6 stop combined to give 16), a tripod and a remote control for your camera so that you can use the camera in it's 'bulb' setting for exposure times longer than 30 seconds. If you have any questions ask away and I'll do my best to help if I can!

@Michael Skorulski: Thanks Michael!

@peter.K: Thanks Peter

@Lorraine: Hi Lorraine!....yes that portrait by Michael is brilliant isn't it. My portrait photography is something I'm trying to improve at the moment (especially now I've got this shiny new camera!) but it's a lot harder than landscape or architectural photography!

@kairospix: Thanks!
