Bokeh Babes

Anouilh · 23-06-2008 5:25pm #1

The Bokeh Challenge is for new photos so I thought it might be an idea to start a "Best Bokeh" from yore thread. Here is my favourite. Circles of confusion make great effects, but I tend to like Bokeh that sweeps across the background.

(I removed the offending graphics link,as it was not properly positioned on the screen. Will re-post at the end of this thread.)

i'd reccommend looking at it full size to see what i like bout it

its hard to see the detail small size

Anouilh · 23-06-2008 5:33pm

That is glorious. Well done!

I posted this thread twice, by mistake, and can't work out how to take the previous version away.
Also, my photo has taken on a life of it's own, turned into a widget, and keeps shooting away onto the rhs of the page on my computer.

Sorry... Perhaps a mod could rescue the situation, please.

Fajitas! · 23-06-2008 5:33pm

Done

I'll have some pics for this in the morning.

elven as i recall has a lovely example of custom bokeh

Many thanks, Fajitas. For some reason my photo continues to leap, uncontrollably, to the right. Can anybody explain what causes this, please?

Fajitas! · 23-06-2008 6:01pm

Looks good from this end, but when you're posting, put a couple of lines between the [img]code and the rest of your text, should sort you out!

Anouilh · 23-06-2008 6:04pm

Thanks again. I'll try that tomorrow.

Ballyman · 23-06-2008 7:08pm

Here's my attempt!

Those lads are gorgeous! Where did you find them?

The cat dragged them in

Fajitas! - Don't forget about the LEDs from the Toast pub when you allowed me to touch your precious thing :-D

Fajitas! · 23-06-2008 8:11pm

Jesus. People really have it in for my reputation!!!

Is bokeh the photographic term for Boquet ? ,as in boquet of flowers ?

Bokeh (from the Japanese boke ボケ, "blur") is a photographic term referring to the appearance of out-of-focus areas in an image produced by a camera lens.

Hugh_C · 23-06-2008 8:22pm

Weird graveyard bokeh ...

ThOnda · 23-06-2008 8:42pm

Mine old one.

Ghost Train · 23-06-2008 9:08pm

does it have to be lens blur?... this would be more motion blur i guess, its a goldfish (and reflection of the wall above the pond)

whyulittle · 23-06-2008 9:09pm

These two for me.

PixelTrawler · 23-06-2008 9:39pm

Mines a simple one

Light through the leaves on a tree makes great bokeh. I like yours alot, Anouilh

v nice bokeh, i'm guessing 1.4 from the curve of the bokeh?

PixelTrawler · 23-06-2008 10:27pm

Is Bokeh just out of focus / blurred background or specifically when you get curved blurry circles - i took this at f1.4

Roen · 23-06-2008 10:28pm

I'd say ƒ1.8 :P

the lower the ap, the more diaphrams thus curvier the circle

Fajitas! · 23-06-2008 10:30pm

It's not due to the amount of diaphrams, but their shape

the increased number causes the shape change no?

PixelTrawler · 23-06-2008 10:33pm

ah, i only have a fast prime a while and I was wondering why you get an almost circular pattern with extreme DOF

Fajitas! · 23-06-2008 10:37pm

Yep, but it depends just as much on their shape when it comes together.

When the lens is wide open, it's at its most perfect circle, hence the best bokeh wide open - As you stop down, the aperture usually begins to form more lines in its shape, and that's when the shape of the aperture blades comes in

lets not forget spherical aberration
The effect is proportional to the fourth power of the diameter and inversely proportional to the third power of the focal length, so it is much more pronounced at short focal ratios, i.e., "fast" lenses.

back to pictures maybe :pac::pac::pac:

AnCatDubh · 23-06-2008 10:46pm

ouch.... my head is beginning to hurt. I think i preferred it when it was just the nice 'blury' bit behind the in focus bit. Too much wikipedia for one night methinks :rolleyes:

Fajitas! · 23-06-2008 10:46pm

Heh... Sorry

ThOnda · 23-06-2008 10:47pm

Shape and amount. I have 6, most pictures here have only 5.
If you place something in front of the lens (but very very close to the lens), the bokeh shape is going to change. That is used by 4x, 6x and 8x stars filters. You can get very similar result by using metallic mesh.

melekalikimaka · 23-06-2008 10:51pm

or a piece of card wih a star cut out

But a lens with say 8 blades at 1.4 still has 8 blades at 22,
its obvious smoother, but the curve of the blades affects it too, as in 6 straight blades will appear pretty hexagonal even when pretty wide

Roen · 23-06-2008 11:25pm

Here's a bit of both the pointy light stuff and over all diffuse light.

ThOnda · 23-06-2008 11:30pm

This is good reading.

Overdraft · 23-06-2008 11:34pm

Jesus, that's a magnificent photo

4sb · 24-06-2008 12:02am

Hardly original.

Mr. Grieves · 24-06-2008 12:10am

Fajitas! is right. At f1.8 I get almost perfect circles, but moving to f2.8 gives very well defined pentagons. I assume at wide open, you're actually seeing the shape of the lens hole itself, as the blades are opened wider than it.
