Digital photography lighting is vital to success. Just like any other method of photography, lighting is a most important aspect of digital photography and lighting or the lack thereof can make or break the look of a photograph.
Quite often, natural light is pretty much all you’ll need when taking photographs. And in fact, most photographers rely quite heavily on either sunset or sunrise lighting conditions to achieve the best shots. Heavy midday sunlight is avoided by most photographers, although novices will generally dive right in, only to find out that not even a polarizer will work during the best of times in bright, midday sun conditions.
And if the lighting isn’t ideal — if the background is overcast or cloudy — most photographers will avoid that as well. However, it should still be acknowledged that you can achieve some great shots from a heavily overcast sky. You simply have to know what you’re looking for with the end result of your shot.
And lastly, when all is said and done and lighting conditions aren’t ideal, quite a large number of photographers will switch to the use of artificial lighting (if they have the equipment). This could range from anything between an an off-camera flash to on-camera flash, or a full blown studio with artificial lighting.
Obviously, your options depend on the situation and what you plan on photographing, but for the most part many photographers will only resort to the use of this method of lighting a scene in extreme cases. There is also the use of reflectors, which can be combined with natural or artificial lighting, but that would require an entirely new discussion!
