Taking pictures underwater is an exciting and truly rewarding experience. For those who are just building their skills, however, there is a wealth of information that must be reviewed. For instance, when it comes to underwater photography – What is strobe falloff is a very common question. Fortunately, this aspect of snapping pictures while snorkeling is not that difficult to understand.
Strobes help to light up the darkness that exist deep below the surface of the water. Without them, it would be difficult to capture amazing shots and take full advantage of all the rich colors that are available. This is especially true when diving to greater depths. Once divers reach just thirty feet or 10 meters in depth, light will have declined significant.
This is also a problem when the sky is overcast. Those who take picture beneath the water have an array of lighting issues that land photographers do not have to contend with. An overcast sky and twilight or evening hours can mute colors and turn a spectacular display of marine life into a dismal setting. Strobes bring light, contrast and vivid color back into the setting and make taking pictures underwater worthwhile.
It is important to note that it is actually very easy to position and use a strobe, even for beginners. This additional equipment will add a wealth of new colors to photos even when the sky is relatively clear and the hour is early. This remains true when just a single light source is used.
Strobe falloff is the amount of light from the strobe that is lost in direct relation to the distance. The power of strobes will be invariably be diminished by its distance from the actual subject. Typically, this reduction in power is about twenty-five percent when the light source is move approximately one to two feet away from the target. Assessing this loss is one of the most complex parts of using this equipment, however, practice in using strobes will make it much easier for photographers to quickly gauge how much power they are getting in different set-ups and shots.
Understanding the power of strobes is vital for choosing the right settings. You will have the option of using a manual or automatic setting. Those with considerable experience often opt for manual settings. This gives them a greater range of flexibility in terms of controlling lighting and capturing colors the right way. More importantly, these individuals have a clear understanding of the amount of power that they will need in order to get the shots that they want and want to be able to use their strobes accordingly.
Manual settings are frequently used by divers who use two strobes. Automatic settings are only best in environments in which natural lighting will not undergo any significant changes and focusing distance remains fairly static. It is often the ideal choice for macro photography.
In order to properly account for strobe falloff, it is best to avoid automatic settings in instances in which the subject will be moving rapidly to or away from your lens. There is simply no easy way to account for these dramatic differences in distance. This is why it is always good for divers to become astute in using and manipulating manual settings in different underwater environments and with different subjects.
