No problem.
It's always worth a try for something different.
Been an age since I used the technique. Can remember doing some shots for an ice hockey team with some mixed results. Rear curtain sync found on most SLR's these days makes a big difference. Would thoroughly recomend using it to catch the blur at the right time ....got a great shot of the puk spinning in the air.....
Would have added it on here a while ago, but can't for the life of me remember where the negs are!
