Recently I did several portrait shootings with internationally successful athletes. The ambition is to set up special lighting using flashes. This blog is about the difficulties that you encounter and how to solve them.
The Basic Setup
First let me explain my typical setup like I used it for this portrait of the European Scratch Champion 2016 Gaël Suter. The customer (Tissot Velodrome) showed me a target picture with a portrait of a 5xOlympic Champion and Tour de France winner (if you know cycling, you know who). That target picture had side lighting as the main artistic ingredient. So I placed my 120cm soft box with grid on the left hand side. This was my main main source of light. Next, I took my 180cm strip light (with grid too) and placed it on the right hand side behind Gaël. The idea was to create a rim light that would separate Gaël from the background (typical for sports portraits).
The rest was easy: Gaël balanced his bike on the rollers and I ensured that I pressed the shutter exactly when his right foot was in the picture.
From still pictures to action pictures
Taking action pictures is considerably harder. This is a shooting that I did with Stephan Wiesner in December 2017 when we met the U23 European Silver medalist Dany Brand. The basic setup was similar, but not identical. One light source (the same 120cm soft box) from Dany’s front (of course now to the side of the photographer). Instead of the strip light we chose five speed lights from the back.
The main problem is to freeze the action. To explain, a flash has a short but not infinitely short burning time. This time gets longer, when the flash is used at higher power. In such cases, the action often won’t be frozen. The usual result is a quite ugly image. So we had to ensure that the burning time was sufficiently short! This meant that the flash had to be at low power. The usual reaction would have been to shoot with wide aperture. However, there was a second difficulty: we wanted to create the star-like look of the flashes in the back. Hence we had to shoot at F13 which is less than half the light as in Gaëls photo. We solved the problem by increasing the ISO (ISO 400) and moving the flash as close as possible. It was just outside the frame.
Moving the light source close is almost always a good idea in portrait photography. By the law of physics with half of the distance you need just 1/4 of the flash power. Moreover, the light gets softer (which was a potential problem here because we also wanted Dany’s muscles to pop out. But, as you can see, his muscles were bigger than the light source was soft 😛 )
