Lets start off with an simple scene (feel free to be creative here :D)
Next off we gonna add an Empty to our scene and also change the snap function to Face
Now comes the funny part, place ur Empty where ever u like and since we activated Face snaping, we can do that pretty handy. just hold down STRG(für alle deutschen :D)/CTRL while moving the empty and voila, get get this
Finally u placed ur Empty, we can now go to the Blur, hurray ! 😀
Choose ur camera and go down to the Depth of Field box, as focus, choose the empty and set ur Blur to Radius/f-stop
Remember guys: Radius and f-stop behave differently, since their values go the opposite, which means Radius/high value –> more Blur / f-stop/high value –> less Blur
(So eventually u have to do the opposite with f-stop, just in mind)
I choosed myself the Radius and increased to value to 1, which gives quite good amount of Blur. You should remember that more blur also means more noise, so dont forget to increase the samples also if ur working with a relentless high amount of blur. The blade value beneath changes the „sprite“ the objects in the background of the blur gives, if there is a certain blur given. So putting the value to 4 blade as example, would result in 4 points, eventually looking like boxes in the background.
A little bit changing here and there … and ur done (as always :D)
For my Final render i also added some compositing effects like the Vignette, which i also made a article, and can be done pretty quickly.
Not much to add here, keep calm and fresh and as always, mess around with it, u might find a waaaaay better spot than me for ur Render ! 😀
