Hi!

I was just thinking about how to add this final bit of reality to M~R images.

Just look at this photo to see what I'm talking about:


It would be cool to activate an image for lens dirt. To create results similar to this.

It's ok to have it for V1.5

what it looks like with RC5

Ha! This is a cool one! Ok then, we need some algorithms for lens scratches, too

woudn't this be possible if we could provide a grayscale color image of the diaphragm's shape?

white circle/ black bg -> circular diaphragm -> circular shaped "dof"
white polygon/black bg -> polygonal diaphragm -> polygonal shaped "dof"
tom's b&w photo -> tom's photo diaphragm -> tom shaped "dof"..

Could be fun, and even useful sometimes

For scratches, we would just have to do a circular diaphragm image with scratches

Great sam7
Nice idea tokiop

Yes, but that's not lens dirt. That's bokeh.

@jfrancis: right you are! I hadn't heard of it yet.

So defining it like here would be cool


Is it related to the Lens/glare definition?
