Long Exposure Sunset

I was out taking this at a local water sports lake and I had a couple of points I thought might be useful to remember for this blog but have forgotten them! I think I'll have to get a ball head for my tripod at some stage, I have a three way head at present and they can be a little cumbersome, especially when composing a shot a few inches above the water. To make things even worse I had to look through the view finder upside down, not the most accurate way of getting the horizon level. This was taken with the 10 Stop filter that I'm using a fair bit lately. As these are so dense (in terms of light transmission) you have to compose and focus with the filter off the camera and then slide it into the holder, although I find it easier to take the filter and the holder off and just snap it on for the shot. I also had a graduated filter to prevent the sky from blowing out, very easy when including the sun. A good idea if you are using these long exposure filters is to get your exposure right without it on then just add 10 stops of light So say 30 clicks of increasing your shutter speed, or if you get to 30 seconds and don't want to go into bulb mode but have only done 6 stops (18 clicks if your camera goes in 1/3 stop increments), open up the aperture 4 stops (12 clicks). It seems a little difficult to get your head round but once you do it'll make things a whole lot easier and you'll always use full manual, for landscapes anyway. This was taken at ISO100 19mm, f/14 for 30 seconds. There is a little lens flare to illustrate my last point, ALWAYS clean your lens and any filters between the camera and subject, be it UV filters, ND filters or Grads, any dust when shooting into the sun will refract it and make the shot only good for blog tutorials or healing brush practice!
