Thats not bokeh! Just some shallow DOF. If you want bokeh, check these pics out ;)





Both taken with the EF 85mm f/1.2 L II. Best lens for Canon for bokeh. PERIOD. Although the second pic did not come out that nicely sigh.
What I said was a calculated guess. Glad to know the correct reason :)

Wow. I thought both are same.
My new understanding: Bokeh achieved by shallow DOF. But not other way around?
Is this right?

Shallow DOF = background blur. Bokeh is the quality of the background blur.

Here's a nice explanation.

DOF

Bokeh

I've seen many people complimenting some shots by saying "Wow, what a depth!" The funny thing is, these comments will be actually for the shots with a shallow DOF, like the portraits posted just above. BTW, nice pictures there SunnyBoi!

Very high Depth of field is achieved with narrower apertures. there will be almost everything in focus in those pictures.

Yes! More even and widespread background blur is considered to be quality bokeh.

I like that hexagonal bokeh for background lights than the perfect round one:

Hehe the pic you posted is heptagonal ;) the shape will be determined by the number of aperture blades. Cheapo 50mm f/1.8 with 5 blades creates a pentagon, which looks very harsh. Better lens with 12 circular aperture blades create OOF circles more or less resembling a circle.

Do a search on iris blur, wish to try it once :D

@sunnyBoi
Nice pics and yeah,me too love those OOF circles in my pictures! This is from a Nikon 70-200 @f2.8.

Now what would we call this, bokeh or DOF ?
102mm, F/4.8, 1/125 sec, ISO-100, Exp +0.7 step

Yes, I actually meant that thing with 7 sides :D

This was taken at f/5.6 so the heptagonal shape. In the max aperture of that lens, (f/4) the blades retract beyond the perfect circular opening so I get perfect round bokeh.

Nice bokeh. It is not DOF, it is 'shallow DOF'. Read it as the expansion of that term then it will make sense :)

@shajufx: Yes this is Bokeh where the back ground is totally blurred. But for an example of good boken see Torqueguru's dog picture in the previous post where the oof areas are a lot smoother and rounded unlike the hard edges as seen in your picture.

I believe the apperture makes that huge difference. My shot is with a 55-200 VR which is 6 times cheaper lens than 70-200 LOL!! I am seriously considering the Sigma 50mm 1.4 EX DG HSM. Hope I can feel the quality difference from an average kit lens !:)

Phew!! This thread is quite informative and very confusing :D

I am getting a Canon T1i (500D) as a gift from my Elder Brother and have been using SX 10 IS for the past 9 months. Now what i need is a link to a tutorial which explains all the terms like Aperture/ISO/Shutter Speeds/Compression and their Usageplease:. Please if anybody has links to a tutorial which is easy on the vocabulary (as in not too many hard words for a beginner) would be appreciated.

Thanks guys..

You can check Dpreview, they have a comprehensive guide for beginners into DSLR's.

@The_Warrior

This is strictly in my opinion. I am also in the process to select my first DSLR ( used quite a few but this will be my own one ) . I have compared the 500D samples and 450D samples. Although , you will be getting a better screen ( 920K dots ) , more resolution on paper ( 14+ ) , but if you compare the photographs from both these cameras , the picture quality in terms of per pixel sharpness and high ISO noise handling is way better in 450D. The quality of images taken by 450D is still quite unmatched by it's peers and competitors in the same price segment.

Hmm after reading your point I revisited some older pics that I took. This pic was of an awesome guitarist who was practising on the side of the beach. Good thing i was drunk, If i weren't drunk i'd never approach him lol. but really enjoyed a live performance :D

So yeah now i believe OOF circles will be round at max aperture. The lights are from far away ships, pic was taken from the beach. excuse the crappy quality, somehow noise and ugly artifacts have creeped in when I resized the pic :Frustrati




+1. Colleague bought a 500D and night time pics were better on my 450D compared to his 500D with my lens and when I took pic from both cams.
