*assuming that the area of the Bokeh is of one color/tone, of course. Remember, depth of field is not just a hard line after which everything is supposed to be completely out of focus it gradually transforms from sharp to out of focus, as can be clearly seen in the below image. I am just not one to focus on the bokeh (pun intended) If the subject you are photographing is very close to a busy background, the bokeh will definitely suffer. I know there are some photographers where bokeh is an important part of their composition. The transitions from focus to out of focus are usually off. Generally speaking, when people try to fake non-existant bokeh into a photo it looks really really fake. I personally have not worred too much about Bokeh. Nick Arora Photo: Im sure " faking" bokeh in photoshop where none previously existed has been discussed here before - but that is not what Im talking about. Some may consider circular bokeh more pleasing than a more angular, but, in my opinion, both can be either good or bad bokeh. But I don't consider that a matter of "good" or "bad" bokeh, just different types of Bokeh and the individual artist may have preferences. One, can't ignore the shape of the Bokeh either. There can be banding or changing of the tones inside each bokeh area. "Bad" bokeh may have darker or lighter rings around each individual occurance of bokeh. "Good" bokeh should have a consistent tone throughout each individual occurance of bokeh*. But in my opinion, regardless of the shape of the bokeh, "good" bokeh should be of a consistent shape throughout the image The shape of the bokeh is influenced by the number and types of blades. On lower quality lenses, the shape of Bokeh can change as one moves to the corner/edges. To me, "good" bokeh is bokeh that is of a consistant shape throughout the image. See timing analysis for more details.Bokeh, like other compositional parts of the art of photography is open to interpretation as to what is good or bad. The example below shows the highlights with a factor of 0.5. Yet others prefer a uniform wall of gaussian blur foreground-background. ![]() To do this, increase the Busy bokeh factor to a value bigger than 0. There are some who like ‘busy’ bokeh where out of focus areas take on double images, swirls or other patterns some like the pentagons and other shapes on highlights. ![]() However you can change the round highlight to be a circle which is more transparent in the center than it is on the edges. With regular pictures, the mechanical shutter determines what exactly is captured from the outside world (that's why you don't see any gradient in a regular CR2), but the sensor is "open" for a longer time. A bokeh highlight is a typical round highlight with an even color. ![]() It simply closes the aperture to f/22 after some time, simulating a leaf shutter (one that doesn't fully close, so it still leaks some light after the exposure "ends").īackground: with current FRSP implementation, which you all know it gives overexposed images, the exposure starts at the same time on all rows (global shutter when starting the exposure), but ends at different times (gradient, top line is read out first, then subsequent lines are going to capture more light - rolling shutter). Bokeh photography can transport the viewer to an almost alien world of scale and color, such as this beautifully composed image of a butterfly. The same trick is useful for getting full-res silent pics with normal exposure at hand-holdable shutter speeds, although with a pretty interesting bokeh. This image is an excellent example of bokeh, with the metallic effect on the bubbles and receding blur of lights offering a sense of depth and dimension. ![]() Common culprits of busy bokeh are chainlink fences, tree branches, and any similar subject especially when lit in a harsh manner such as from direct sunlight. Unfortunately I couldn't get it to work with regular CR2 files. Example 5 is the absolute opposite of example 4: the bokeh is harsh and busy, and overall distracts the viewer more than it helps them focus on the subject. Busy bokeh, on the other hand, is any type of blur that still has more noticeable shape or texture than usual, sometimes creating distracting patterns or lines. The creamy bokeh images were actually full-res silent pictures with variable aperture. They both look quite similar to the Z lens at this value, whereas the 1.8 G continues to deliver an unpleasant and busy bokeh. There was no postprocessing, other than developing the raw files (CR2 or DNG) in ufraw. At f/2, you start to clearly see bokeh balls emerge in the examples taken with the 1.4 lenses. Taken on a Canon EOS R with a Canon RF 85mm F1.2L USM lens at 1/800 sec, f/1.6. Tuning has to be fine-tuned manually for each shutter speed (at least at this stage). A portrait of a model in a white jacket in front of a busy but blurred. The former can adjust the aperture smoothly, while the latter can only do discrete steps (therefore the larger exposure time).
