The Truth About Natural Light vs. OCF

I have seen many posts on social media and magazine articles about how much better Off-Camera Flash (OCF) is than natural light. Most examples I’ve seen have just been bad examples of the use of natural light. Natural light portraiture is not just creating a correct exposure outdoors anywhere. The use of light, whether natural or artificial, has a specific and artistic placement that will create the look that the artist desires.

The truth is that natural light can be pleasing, but the artist is limited to locations and specific times that will allow a powerful, printable result. On the other hand, off-camera flash can be used to create any chosen form of light in any given area at most any time. Of course, there’s a great deal of technical and artistic thought that should go into either process.

Let’s begin with a good natural light portrait area. Just as with strobe lights, the main light on a subject should be at about a 45° angle to the side and 45° up from the subject. This is a good place to start. We can’t have more light coming from straight above than where the main light is coming from. For this reason, we look for locations with an overhang to block the light from above.

Some good advice: if you’re not sure the area will produce good natural portrait lighting, go sit where you plan to place your subject. As you sit, look around you. Do you see an area of open sky at a 45° angle? If you don’t see a light source, either go find a new location or add off-camera flash.

In addition to the correct direction of light, in a natural light situation, the background must confine itself to a continuous tone of light. In other words, there can’t be direct sun in the background burning out areas in comparison to the subject. If the light reflecting on the subject’s face is the brightest part of the scene, it is what will draw attention of those who look at the portrait.

If there are distractions and technical problems with the background, even the nicest light on the face will be for nothing. I look for open shade throughout my backgrounds. Then if the subject sits where the open sky is forced in the direction stated, your image will have the potential for power. I say “potential” because there are many more things to consider (color harmony, posing, expression, clothing, story-telling, composition, etc.).

The image on the left shows dark eyes. The background is great but the light is too powerful from above. The image on the right of it shows how Off-Camera Flash can create the direction of light needed to produce a pleasing portrait. With the dog (above), a good background and the use of Off-Camera Flash gave direction and, in this case, fur reflection.

Now… the Truth about OCF. With flash, we can work in more locations with more background possibilities. As I stated before, sit where you plan on having your subject. If the light is not right for your image while still seeing the background for the composition you desire, you can simply move your light. In today’s world, lights are very portable and have great battery life. They are able to nearly over-power the sun at times and (more important to the way I work) they can be turned way down to allow work in low light areas.
The Truth… you can produce work in more locations. That being said… just because we can doesn’t mean we should. Not all situations are going to work for either OCF or Natural light portraits. We still need to think about what is physically possible and still artistically pleasing. Remember, the light from the strobe only goes so far. If there are objects in your scene beyond the range of the strobe and there is no way to balance the background with shutter speed, you may want to move on to a new location. Example…. A client has a wooded yard on a lake. They want to see the water and the trees and, of course, them in a portrait. Even with strobe, you will need to find the right time of day to balance everything.

Even in a “sweet-light” atmosphere there are times when a little pop of an OCF can help. I like that my Molight can be turned way down. This way I get a more natural feel to my location portrait work. I use the Molight AD600BM as a main light. I use one or two AD200s for accent lights or even main or fill in different situations. I also like the Molight Octa Box. I use the 32 inch version without the baffle inside.

Whether you are using OCF or going all Natural, you still need to make sure the light is being directed to the right place on your subject. There are forms of light to study. Learn them and the best uses of each. In the end, we as artists, are responsible for creating work for our clients that are appealing to them and their families. Whether natural or artificial, practice your skills and be able to make good decisions in any situation.
