WEEK 2 -"BOKEH"

Bokeh is different from sharpness. Sharpness is what happens at the point of best focus. Bokeh is what happens away from the point of best focus.Bokeh describes the appearance, or "feel," of out-of-focus areas.Bokeh is not how far something is out-of-focus, bokeh is the character of whatever blur is there. 

In photography, bokeh (pronounced /bɒkɛ/^[1]) is the blur,or the aesthetic quality of the blur, in out-of-focus areas of an image, or "the way the lens renders out-of-focus points of light.Bokeh is often most visible around small background highlights, such as specular reflections and light sources, which is why it is often associated with such areas.However, bokeh is not limited to highlights; blur occurs in all out-of-focus regions of the image.

The term comes from the Japanese word boke (暈け or ボケ), which means "blur" or "haze", or boke-aji (ボケ味), the "blur quality". The Japanese term boke is also used in the sense of a mental haze or senility.

The rendering of out-of-focus (OOF) image parts does not enjoy a large weight in the overall design compromise of a normal photographic lens. However, the OOF blur characteristics mattered to certain Japanese photographers who introduced the term "bokeh" to the photographic society to describe the aesthetic quality of the blur. In the absence of a single English word with the same meaning, there seems no reason not to adopt the Japanese term. The internet abounds with lens qualifications like "good bokeh" and "bad bokeh" but strictly speaking this use of the word should be discouraged.  

This blur disk is characterized by

1. A size.
2. A shape.
3. The light distribution across the disk.

Here are several examples of bokeh's pictures that i found :

what do you think about all this pictures? :)

There are some techiques how to make this bokeh :

Step 1 :
Bokeh usually works best when taking an up close picture of your subject, try finding a  subject with nice clear lighting that you are able to get a good close up of.

Step 2 :
Slightly unfocus your lens so that the image is now softly blurred. The image background will be significantly blurred, but try keeping the foreground image, your subject, recognizable

Step 3 :
Set your exposure time according to the amount of light present.

Step 4 :
Now set your aperture to a lower f-stop number so that the aperture is opened wider. Having the aperture on a wide setting will help keep the picture in soft focus.

Step 5 :
Look into your viewfinder and inspect the frame for any sharp lines or clear details in the background, this is not wanted in a Bokeh picture.

Step 6 :
Now take your pictures. 

(Self Review)

In conclusion, bokeh is a pictures which is have a blur background. If we are using bokeh for our pictures it will make the subject in our pictures will be the main focus and make our pictures more interesting.
