BOKEH EFFECT IN VRAY SKETCHUP . . .

Bokeh effect is defined as “the effect of a soft out-of-focus background that you get when shooting a subject, using a fast lens, at the widest aperture, such as f/2.8 or wider.” Simply put, bokeh is the pleasing or aesthetic quality of out-of-focus blur in a photograph. 

V-Ray also offers a feature to simulate this type of effect: enable the depth of field and just flag on “blades” 

Trial 1 | Aperture (f number) 8.0 | Shutter speed 300

Trial 2 | Aperture (f number) 1.0 | Shutter speed 300
https://c2.staticflickr.com/6/5778/22720651406_9383037e01_h.jpg
Trial 3 | Aperture (f number) 2.0 | Shutter speed 125
Trial 4 | Aperture (f number) 2.0 | Shutter speed 60

3 important things to affect DOF "Depth of field" 
 Adjust or increase Blur DOF effect
  • Using a bigger Focal length
  • Reducing the distances from the subject (actual distance of camera to object)
  • Decreasing f-number
Note : The more you decrease the value of f_number more strong effect in DOF "Depth of field"   -  -

EV (Exposure value) a combination of a shutter speed and an aperture "f-number" setting, independent of any ISO setting.

I have lots of trial and error...correct me if I'm wrong about the setting and I need a comments and more suggestion if you have. :) GOD BLESS

Featured Visualizer: Zernan Suarez
Some of us can still recognize these excellent images done in Vray SketchUp. Who could believe that most of these works were done with the old VraySU 1.05.33.Well, the man behind them is Zernan Suarez, aka "Zdesign". Zernan is one of the famous visualizer at http://www.cgpinoy.org/ using Google SketchUp and VraySU. I myself is a fan and  follower of  this man. I love the way he creates his scene with dramatic lighting. Zernan's is also a generous and regular contributor of excellent tutorials when it comes to visualization.

If you remember, this vray for sketchup rendered image is one of my entry in September 2010 Chaos Group Vray Render Contest and it's included in one of the pages of CatchUp – SketchUcation Community News – Edition 1
Thank you very much to sketchucation and the Daily Catchup
