Depth of field question

Illidanstorm

I want to make a closeup shot and want the background to be very blurry but can't do it.
If I increase the F/Stop so her whole face is in focus, the background becomes less blurry, which is what I don't want.

How can I make the background very blurry on a faceshot and still have the whole face in focus and not just the nose?

Use a longer focal length camera, 135/200mm, and pull it back to frame the shot and use a small F/Stop.

If this won't help me I call myself a total dumb >_< Been fighting with DoF in DAZ for days. I recently moved from Poser and in Poser I set up DoF in seconds but not in DAZ. I must be doing something wrong... even following tutorials >_<

Aaaaaaand... I am dumb. I will NEVER get DoF to work in DAZ. Followed every tutorial I found, made all steps with double-check if I did them right - nothing. I give up. All hail to those who are able to get DoF which is ridiculously easy but obviously I'm too dumb *cries*

You are turning it on in the camera settings?

I find it simplest to handle DoF with 2 cameras - let's call them SceneCam which is the camera going to be used for the actual render, andf PoseCam for the camera going to be used for looking round the scene and looking at things (coudl also use the perspective view for this).

First off, and obvious!, get the SceneCam in the right position for your scene - pointed at youe figure (or at teh mainpoint of focus you'll be wanting).  With SceneCam selected in scene tab go to the Lighting/Camera tab and under the Camera settings ensure that Speth of Field is On. Then go to the Display> Scene View> Deoth of Field settings and check that DOF Plane Visibility is On (it shoudl be On by default), and set the DOF Plane Color to somethign that will contrast with the rest of your scene (I usuallpick full red, 255,0,0). This should allow you to pick out the front and back DOF planes which wil bracket the volume that will be 'most' in focus.  In between these two planes you'll see a little 'reticle' which indicates the actual point of focus.

Now switch to your other viewing thing (PoseCam or perspecive view).  Depending on where in the scene your ScenCam and point of interrest are you may find it useful to, in the scene tab to seelct both the figure (if there is one) and the SCenCam (using ctrl-click so you can select both), then eitehr use the 'Frame' icon (little + in a partial box) or press Ctrl-F.  You'll then be able ot swing the point of view to a right angle of the SceneCam. 

Now seelct teh SCeneCam again (just it this time) and you shoudl see it's direction and view area, along with the two red DOF planes and the focal reticle between them.  Adjust the Focal Distance setting under Camera parameters and you'll see the reticle move (teh two DOF planes will also adjust a bit as you do this).  When you have the reticle palces as you wish then adjust the F/Stop setting (again, udner Camera parameters) and, hopefull, you'll see the two DOF planes conract or expand depending on how you adjust teh F/Stop (lower narrows the DOF area).  Don't mistake these F/Stop settings with anythign to do with real cameras, so just adjust until you get what you want!

Of course. But nevermind, I found solution and FINALLY get DoF. I'm using the script to calculate focal length precisely, from here https://www.daz3d.com/forums/viewthread/43636/

It didn't work for me. But as said, I have a script now and can spend more time on fiddling with lights and textures which is my fav thing :) instead of calculating DoF manually.
