Everyone is talking about bokeh, but nobody does anything about it ... Seriously: Is the enthusiasm for fast lenses that depict motifs offenblendig before an extremely blurred background, just a hype, whose time slowly passes by?
Okay, "bokeh" is the wrong term, even if it is often used in this context. He finally referred to the quality, the particular kind of blur outside the focus area, and not its quantity - ie the degree of blur. No one has anything against a pleasant, soft bokeh, but the background shall be so blurred really that you can not see anything more?
The video blog "Camera Conspiracies" recently with biting sarcasm the desire for more and more background blur criticizedAs for example, a YouTube video illustrated by Tony Northrup. Northrup explains the fact why hardly anyone - on YouTube - uses 4K video, and the vast majority of the content is to be uploaded before in a HD resolution. By contrast, leaves little to say, because that's the way - everyone is talking about 4K, but in practice you do not need it. virtually not existent - - background on but Northrups video that he recorded with a 50 mm f / 1.2 lens on a Canon EOS RP, especially the fuzzy falls. Camera Conspiracies irritated, because there acts a man in a indeterminate nowhere - the video could have been taken anywhere in the world.
In the world as we see it, there is no blur. Although our eyes have a limited depth of field, but we can anyway look really sharp only in a very small part of the visual field, our environment must therefore scanned point by point, and since the eye sharp, each detail that it considered, we see more and sharp images - if not, then we are fehlsichtig and need glasses or contact lenses to ensure a sharp image again. While the eye saccades to another point pivots or while it focused, the brain ignores the signals of the photoreceptor cells, and from the sharp images, it creates a model of the world.
An exemption is the subject of videos anyway hardly an issue, because only the subject movement range to differentiate it from the stationary background. But in photography, one may wonder whether the background should be mapped so blurred that you can not identify the context. A hundred years ago photographer used a as Erich Salomon highly fast lenses to - unnoticed - to work with the available light, but a shallow depth at that time was not as desirable. Today, the cameras achieve ISO values that allow light photography Available also with moderate light levels yet, so extreme light intensities are more appreciated by bokeh fetishists. But really win our pictures if you do not even both eyes reflects sharply in a portrait photo, not to mention the very tip of the nose?
