I recently added the B&W ND110 to my filter collection and whilst I haven't dabbled in any daytime long exposure, I finally got a chance to "road test" it today.
It's always pretty tricky finding a good subject for long exposure that hasn't already been done, especially during the day and whilst this can be considered an experimental test of sorts, it turned out ok for a first stab.
I set the camera on the tripod, manually focused the area to include the shadow cast from the groin at the center of the picture. I experimented with a few different aperture values and eventually settled on f22, although I prefered f16 initially. I then worked through various different exposure times and found a nice balance at 30 seconds.
Once I had my shot, I took 3 different shots using various white balance levels (to help bring out the blue in the sky and the sea) and then merged the three shots, toned down the bright yellows and magentas of the pebbles and finally cropped the photograph a little so it was perfectly level.
I don't feel like I got the best out of the filter on this occasion, but it was a good session of exploration through trial and error to see what I could create and with a far more interesting subject I now feel mildly confident of producing something far better.
