Tips for understanding the lighting: Reverse Engineering of portraits

Reverse engineering of photographs as an exercise never hurts to think and learn what other photographers do and ‘discover’ some details that can help us improve. Thinking about the issue of lighting and portraits always there are several elements that can set us for more information than we can see at first glance.The details do matterSay it is not an exact science but when you catch the trick is really fun and interesting. Actually doing this exercise we do is educate our eye, we look for to see a picture and know by looking at certain details read light.

The brightness of the eyes or CatchlightFirst, catchlight sometimes for the layman is confused with the nasty red eye (though even this phenomenon is red), is a mistake and nda further from reality. Catchlight or Shine Eyes is a photographic term used to describe the specular reflected light in the eye of a subject and coming (obviously) of a light source. English also find references looking for ‘Obies’ or ‘eye lights’. Just Obies is a reference to a series of photographs taken to Merle Oberon, actress starred opposite Laurence Olivier’s classic film ‘Wuthering Heights’.

It is a phenomenon that occurs not visually jarring and rejection of the far red eyes. Although it can sometimes be strange and should control it well. As a benefit of this effect focus greater attention on the eyes as well as a contribution of higher dimensionality or volume thereof.The location of the catchlights is determined by the pair of light: more light main light fill. Is its height, angle and distance from a fixed camera that position. The appropriate approach is a reflection of this type for an eye, if we consider the eye as a clock that ideally catchlights appear at 10 or 2.

Through these catchlights can guess if you used an umbrella open or closed, whether it was a softbox square, rectangular, circular or octagonal. That is, the type of primary light source. other details Also by looking at the shadows of the nose, the subject’s clothing or the shadow of the chin can deduce the position of the main light and the rest. At least the lights principals.

When it comes to a larger scene of what may be the common types of picture plane, finding the subject of whole body in conjunction with other elements is usually much more complex. But in addition to following the same technique by following the lights and shadows, we have some more patience.

Focusing on a picture to use, other items that we usually provide much information on rear or side lights are the edges of the face, neck, shoulders, … etc., which can give us an idea of whether you have used other light sources or not.

As you practice and making this kind of ‘reverse engineering’, sure you’ll see that little by little when you see an image you will automatically deducting surely, at least, the main lights used in it. Practice will give good results for sure. source:xatafoto
