aul, shooting in full sun is tricky! Here are some ideas, in addition to using high speed sync:
- Just work with the sun and pose your subject to avoid harsh shadows.
- Diffuse the light on the subject by using a diffusion panel. This will lower the value on the subject while keeping the same value on the background - you may overexpose the background for a high key look.
- Add light to the subject by using a reflector that bounces sun light on your subject - this is particularly useful if you position the subject with the sun behind him/her and not redirect the sun light to the face with a white reflector. A silver one will produce too much specularity and cause squinting. Note also that when you add light to the subject you'll raise the value while keeping the background constant - this will darken the background when you expose correctly for the subject - perfect for lower key portraits
- Add light to the subject using a flash - instead of a reflector. You'll run into the sync speed limit unless you use high speed sync, but the principle is the same. In order to shoot wide open without high speed sync you'll need neutral density filters and a powerful strobe.
- Move to the shade and now use either reflected sunlight or flash (diffused or not) to create a sunny feel.
Here are some examples I have posted here in the past:
1. Just work with the sun and pose your subject to avoid harsh shadows. In this case I didnt use anything, just made sure the model was positioned right to achieve a "sunny" warm feeling.
2. Diffuse the light on the subject by using a diffusion panel. This will lower the value on the subject while keeping the same value on the background - you may overexpose the background for a high key look.
In this image below I had a large 4x6 difussion panel over the model in full, hot sun. The panel created soft, nondirectional iight. In order to avoid an overexposed sky I shot from above and used the grass as background.
3. Add light to the subject by using a reflector that bounces sun light on your subject - here I used a large reflector in front of the model - the light on her hair is the sun, slightly behind her, and the key light on her face is also the fun but reflected and diffused by the large reflector. The reflected light was a bit too strong and made her squint a little.
4. Add light to the subject using a flash - instead of a reflector. In the image below, taken in full sun, I overpowered the sun with massive 1,200 ws of strobe power for an unnusual effect.
5. But overpowering the sun is usually not needed, you just need to light the face when pointing away from the sun - I did that in this portrait below. The key light was a x-small Photoflex softbox with a portable flash. As above, the light on her hair is the sun, and the light on her face is the flash + sun.
6. Move to the shade and now use either reflected sunlight or flash (diffused or not) to create a sunny feel. That's what I did here, for this recent portrait of Salma. The light on her hair and arm is not the sun but a bare bulb portable flash - the day was cloudy and dull, but I wanted sunny and spring-like, so I created the perception of sunny by adding flash to the side.
