When I posted the images from my previous movement session online, I got an instant response to the images, and other dancers wanting to take part. Hayley introduced herself as a Salsa dancer who had a number of flowing dresses, so we set up a time to shoot.
I used the same hall as for my earlier shoot, however having learned from the first session, and reviewing a different YouTube clip, I made a couple of changes. The most notable were to make sure I had a second light bank and a much bigger (and taller) backdrop. The new lights were two Interfit continuous lights borrowed from a fellow photographer at work. While not being particularly strong they were more than adequate for the long exposure work. I used a small light stand and boom arm to set them one on top of the other giving me an effective stripbox. I had them positioned behind a large reflector so their light was fairly concentrated. The diagram below shows the layout.
In these circumstances you have to work solely in manual and therefore the first shots are generally trial and error. Focusing is also on manual by selecting a spot roughly equivalent to where she would be when the flash fired. Given that the camera was set at f11 I knew that there was a degree of flexibility in the depth of field.
I initially had the computer tethered to a laptop as this made showing the images to Hayley a lot easier. Unfortunately it is fairly old and struggled to keep up so ended up being ditched. Tethered shooting is really good when it works but can be frustrating when it plays up.
Hayley had a number of outfits which we moved through. He initially one ended up only being used for the test shots as it was blending too much in the background. The lighter coloured dresses worked best, although the speed that Hayley was dancing did cause some issues. With long exposures if the subject is moving quickly then rather than a blur, they simply disappear. Trying to find the right balance in the speed was important.
At one point we placed a red gell over the continuous light to see what effect that would make, especially when she was wearing a white outfit. I would rate this has been only marginally successful. When Hayley was over by the gelled light the red came through strongly but it was too far away for the main light to be fully effective. When she was closer to the main light the colour was essentially bleached out by its strength.
Towards the end of the shoot I changed tack and tried to get the images that would essentially freeze the action. Leaving the existing lights in place I introduced a third lights which I shot into a large silver umbrella. The shutter speed when then put up to maximum sync speed and I shot some images of Hayley jumping.
