Firstly many thanks for the votes and congrats to the other placed entries. It was a great theme and there were lots of great photos.
Here is my back story.
This year I made the resolution to enter the MBP monthly assignments to get me taking pictures. Something that I had been neglecting last year.
I had the idea of the breaking block of ice when I first saw the assignment title. I liked the idea of using the ice as a lightbox for a slide and set about testing the freezing process.
The first attempts were ok although with the slide buried deep in the ice, the picture itself wasn't clear because of frosting.
Finally with the month slipping away I managed to get the slide to stay on the surface of the water as it froze in a plastic tub.
I set up my studio with a black card background and white card base to reflect the light.
I wanted to use Nikons Auto FP mode for this to maximise the shutter speed. I used two SB800s, one placed behind the block of ice and one front and camera left.
The settings were 1/8000sec F8 Foreground flash 1/1 power; Background flash 1/8 power.
I knew this would be a one shot effort and couldn't use high speed continuous due to the flash recycling.
I braced myself with the lump hammer, a wireless remote and hoped for the best.....
It was close to what I wanted and I was very happy not to have caught the hammer in mid air !
I have enclosed a couple of shots to show the aftermath.
I had another couple of swings just for the help of it and then it was time to tidy up and apologise for the noise.
Post processing was limited to a crop, white balance and the usual sharpening etc
Many Thanks again
