For the image I've used Thgeisel's setup......... Nerd's Backdrop prop and Dark Whisper's Princess Mandi. Still experimenting, but adding depth of field to the Firefly render is improving things further.

F-Stop is checked in this render. For the Focal distance I've found, as a rough rule of thumb, that adding 10 to the camera's Dolly Z distance (units in feet) gives a good result. F-Stop can then be set as desired with lower numbers giving shorter depth of field. In the image I used F-Stop 8. This nicely blurs the junction between the water plane and Nerd's prop.

good job ! didnt play with the f-stop till now. so many new things, and so little time!

:) I know the feeling........

And...just a thought.....Depth of Field may also be dependent on the camera's focal length. Haven't checked that..but in my setup I've used 80mm......

The main and auxilary cameras are effectively offset from the origin by one Poser unit, which is (approximately) 8 feet. This (8) is therefore the amount that should be added to compenstate for the offset for figures approximately at the scene centre. It may be worth considering using the dolly camera which has no offset from its origin if the camera position to focus object is more complex. Don't forget the Nudity flag :-) Bill

er........ sorry, Bill, but I did....

I worked on this scene for so long I forgot about the young lady.....concentrating too much on the water...

Thanks for the tip on camera offset

I worked on this scene for so long I forgot about the young lady... Now this is just plain wrong. ;)

ian: "Depth of Field may also be dependent on the camera's focal length." yes, you're right - well, at least in the reality. the biger (larger, higher?) the focal length, the harder is to get the background to be blurred. if you have short focal lengths, your background will be blurry even in short distances. if you are going for realistic backgrounds with the teleobjective you must consider that your backgrounds should stay rather sharp. maybe if someone would ask in the photo forum for the right values, i don't think my english is sufficient to make myself clear ;) one question though: there is some jagginess around her hair on the shoulders and on that vertical white spot left from her head. are those compression artefacts or is this the firefly blur-algorhythm (i think i remember dimly that i saw already those things on another dof experiment)?

Were is that hair from?

The hair is also from Dark Whisper...we're not supposed to plug stuff available in the Marketplace, so I won't;-)

aleks,

"there is some jagginess around her hair on the shoulders and on that vertical white spot left from her head. are those compression artefacts or is this the firefly blur-algorhythm (i think i remember dimly that i saw already those things on another dof experiment)? "

The "white spot" jagginess is from the background picture used....... I used only a small part of the image in my scene. I'm not sure what is causing the others. There are many variables in the FireFly engine in addition to compression artifacts that could produce jagginess.

It's early days yet, but so far I'm impressed with the Firefly engine. But it seems to have learning curve similar to the one I went through last year with the finalrender engine in max. :)
