Blurry / Depth of Field Implication

Recently noticed something. Tagging "blurry" seems to implicate the "depth of field" tag. This doesn't make much sense considering the two are not mutually exclusive.

While "depth of field" certainly does implicate "blurry", "blurry" does not necessarily implicate "depth of field".

What if there is an artistic blur over the whole image? In such a case there is no depth of field. Depth of field implicates only part of the image is blurry while the rest is not.

Guessing something accidentally got linked at some point.

Just thought I'd throw it out there.

It doesn't though, look at blurry -depth_of_field, whereas depth_of_field -blurry has no posts.

depth of field implies (and is currently a proper subset of) blurry

Apparently it does though because it's happened more than once to me. I tag blurry. Nothing more. And depth of field pops up.

Then I try deleting depth of field from the post and it won't go away so long as the blurry tag is present.

Thus my confusion. Tested exactly what I said just now. Same result. Something is funky somewhere.

On post #2716872 and post #2722964 you tagged bokeh, which implicates depth of field, which implicates blurry.

Hmmm, while I find it odd, that would explain it. Didn't realize bokeh implicated depth of field. Doesn't seem logical to me so never thought of it.

Bokeh is more an issue of lighting than of depth. Actually, the wiki description even warns not to confuse the two since they are not the same.

I any case, Bokeh -> Depth of Field -> Blurry. That's why so question answered.

Thanks for the straight forward explanation.

Huh? Nowhere do I see that the wiki says not to confuse bokeh with depth, it says not to confuse bokeh with lens flare. They look similar, but lens flare is sharp and travels in a line, while bokeh is blurry light particles from being out-of-focus.
