Something that I would like to do for a long time, to give more realism to the images, and that until recently I did not have the remotest notion of how to achieve with DAZ Sudio, is to make the camera focus at a certain depth, and the rest of the scene appears slightly out of focus, just as our eyes actually work.
I recently found the tutorial on how to achieve it, it basically consists of assigning to the range of vision of the camera an area that is in focus, and everything else will be out of focus by a percentage that can be varied. That's why I specifically created this scenario in which the guy is having a great time with the girl's gigantic feet, since I wasn't sure how well the blur would work in an area of a few centimeters, and I wanted to test it with several meters of margin, being the zone that was focused the one of the feet. As you can see this time I didn't achieve what I wanted, and everything looks equally focused, so having done this already late, and about to go to bed, at least I left the computer rendering various angles of the scene. However, the next day I tried again...
