I think in that case you could just lower the fstop and raise your shutterspeed to get a more pronounced dof effect while keeping the illumination the same.

Hello diego,

I am also testing out DOF feature (for mayall) and a couple of things I found out are;

Not only the shutter speed and f-stop are important, but also other points are important such as setting FOV (zoom), Focal distance, and scene size and placements of objects also affect amount of DOF you get.

I am doing some test contains models in the foreground, mid and background spaced at more than 100 units (in cm), with;

fstop = 0.5,
focal distance = 20,
focal length = 35mm (FOV = 54.432)
shutter speed = 50000 th of a second

objects placements are ;
foreground obj = placed at 1 unit from a lense
mid obj = about 20 units
background = more than 100 units

Maybe using MXCamera's center of interest checked and adjust by using Maya's camera's center of interest manip later would help find the focal point. ( Or you can also try camera's center of interest Unchecked and use the focal distance)

Try adjust FOV as well - narrower you get more of DOF, I think.


hope this helps,

here's something for you...

Diego there's a camera bug in maya, to get DOF try use a Focal length higher than 180 for example, 1/8000 shutterspeed, 1 Fstop (see http://www.metinseven.com/article_maxwe ... tricks.htm) and play with the Focal Distance (use the distance tool to get your Focal Distance).

Here's a couple of examples:

Tom's DOFcue tool is amaizing but because the maya bug you can't use it at the moment (hope along this week we all can use it!! )
