Well this series was created with the awesome Iris at the Studio! The main light for these images is the Stripbox from Elinchrom with a grid attached to it so that we can really focus the light where we want it to hit!
If you want to create the same look as on these images it is really important that you as the photographer shoot towards the light and because of the use of grids you will not have any issues with lensflare!
Also don't feel afraid to direct the model in her poses since she has no idea where the light will be hitting her!
