The key part of this shot was getting the background exposure and composition right, then adding enough light from the flash in my left hand to expose Helen properly.
The photo above and the one below were both taken in the same place at the same time, the difference being the second has a flash illumination the background, while Helen is lit by natural light. The flash is laid on the ground just to the left of Helen's foot, pointing towards the wall behind her. If I had taken some gels with me I could have changes the colour of the wall to better contrast with her hair. (Maybe next time).
And that's it for this set of photos.
Thanks for reading and a big thankyou to Helen for being an excellent subject as always.
