You're creating the condition under which bokeh becomes apparent. You're manipulating whether the background is out of focus or not. That in and of itself is not bokeh. That's the background is out of focus or it isn't. If the background is out of focus (you're responsible) then bokeh will be visible as a property of the physical design of the lens used. Bokeh is the look and character of the out of focus region as a function of the physical lens design. You're not causing the bokeh because you didn't design and manufacture the lens.

Correct! The continuing confusion between background blur and the meaning of bokeh.

Dennis, no question with that example you created a ton of blur. In fact the blur is so all encompassing that no aperture edges can be seen. With this example it would be challenging to even assess the quality of the blur in the way bokeh analysis works.

Short takeaway ..blur does not equal bokeh.

That "definition" concerning specular highlights is waaaaaaaay off base. They are explaining what could be reasonably called "Bokeh 2.0". Bokeh 2.0 is basically online misinformation that was adopted by the marketing operaters of the photo industry. Wider apertures cost more, and that cost rises more steeply with longer focal lengths. Its a marketeers dream.

Bokeh "1.0" concerns the rendering of imperfect but reasonably well focused image edges and details. This is what differentiates "vintage" from "modern" rendering, even between two lenses of similar resolution and visual contrast.

The Asian term "bokeh" leached into the Western vocabulary via those eternal discussions about the mystique of Leica imaging ... not about any quantifiably terrific "IQ performance" but about their "magical rendering".

Bokeh 1.0 is in no way at all concerned with visually way out of focus imagery.

I have to disagree. The question here isn’t whether it’s bokeh or not. It qualifies as bokeh. The question is whether it’s good bokeh or not.


Absolutely. It is a quality issue, not a quantity issue.

I think I know what Bokeh is but I am don't know how to produce it. How do you make it happen?

Personally I love Bokeh but I rarely take the time to achieve it. It really takes time to set the camera so you receive this desired affect.

It is a product of background, focal length, and aperture. And maybe, just maybe, the most important part is the background. You can have lots of blurry background without a good Bokeh.

You want great bokeh...buy a lens that can do that well...it's that simple.

I agree that a lens has a lot to do with acquiring good bokeh, but it's not as simple as placing all of the responsibility on the lens.

In fact it is. Bokeh is entirely a function of the lens design -- the bokeh you get in a photo is the bokeh that the specific lens you're using generates. An out of focus background, which is not bokeh, is the responsibility of the photographer and can be achieved to varying degrees with most lenses.

Nothing is an absolute.

Put it this way then...without a lens designed to give great bokeh...you won't get great bokeh.

You can't make it happen on your own.

Nonsense -- lots of things are absolutes. How about; molten rock ejecting from a volcano is hot.

You just stated an absolute. Here's another one: Bokeh is a property of the physical design of the lens.

Oh, then how about; your camera won't record an image in the absence of electromagnetic energy.

Or, how about; Bokeh is a property of the physical design of the lens.

Agree. It seems that too many people are mistakenly equating bokeh with background blur. As your post points out, bokeh is the lens specific quality of background blur, not the background blur itself.
