[monitor]

The capality to add a atexture for color the bokeh effect (like corona render)

This is quite rare effect and in most cases of bad optics.

I agree that those examples aren't great ones. And yes, it is an artifact from bad optics. But, it can sometimes be quite desirable in both real photography and rendering. This lens is a very very old design that was brough back with its imperfections for its artistic capabilities, https://www.meyer-optik-goerlitz.com...oplan-100-f2.8. This is a better example of how having some aperture alphas could be used well, by Bertrand Benoit with vray, http://bertrand-benoit.com/blog/wonky-bokeh/. (Look at the examples with slightly non-circular alphas, not the stars and hearts that are just for fun). It's not a feature that is high on my list, as I think the current bokeh in FStorm looks great, and there are other features I'd like to see implemented sooner. But its worth bearing in mind. Also worth noting, it can be an absolute killer when it comes to render time. Or at least it was with vray.

This is what I'm waiting for! I have the Trioplan100 and love the artistic rendering of it. I have been trying to recreate it digitally and could do it with corona pretty well. But not on my favorite engine FStorm yet.

Beautiful creamy DOF is a great feature of FStorm. But not all lenses have smooth creamy DOF. Some lenses including modern ones create harsh 'busy' bokehs.

Lenses like the 'Nikon 135mm DC' even has a 'Defocus Control' ring to adjust the style of out of focus area.
Being able to tweak DOF feature further in FStorm will only takes it further towards photorealism.

Here I have attached 2 pics to show what a custom map can do.(ignore the colors and lighting, only want to point the OOF area)
One is the FStorm smooth DOF, and the other is a Corona with a custom bokeh map. In corona I have used a ring shaped map to retain a round shape in the OOF area.

Maybe this is not a urgent feature for you but I hope it is in your 'to do' list. We know Andrey is working hard and always listening to everyone and fixing things we appreciate it! Thank you, FStorm rocks!

You should use the same lighting to compare the dof.
In FStorm scene you have environment brighter than leaves.
I Corona scene you have leaves brighter than the environment.
Adjust the lighting first, then compare.

I was just to point that out, by correcting the light in any of the two samples the final result'll be a lot more alike, but a custom bitmap as aperture, or at least an option to set the blades amount and the roundness would be very useful

and maybe a parameter for adjusting the "sharpness" of the out of focus area?

[JDE]

Fstorm should use something similar that Frischluft DOF plugin does.

Especially the functionality of Border thickness and Border brightness is most valuable in the desired results.
Please check this plugin out for AE, Fusion and bunch of software.

I use this plugin ALWAYS, is there any version for 3d studio?

No it's just for post
But what if implement at least some of it's artistic approach with fstorm, would be cool to marry them Karba!

BTW the topic started about some aberrations which is really can be done on post easily, and it's cheap lenses.
But pretty expensive and nice optics have this kind of "fresnel", feeling of more structured scene and this nice flow and shape behind your focal point - that's what we want to have out of box =)

[Karba]

I will think how I can improve the DOF. I have some ideas.

I understand Karba, I converted the scene from Corona to FStorm and the lighting changes a bit. But my point is not just related to the lighting. It's the style of the bokeh. Here I did another quick render to compare the out of focus area.
In the second image I added a custom bokeh map. You can see it produces almost a painterly effect in the OOF bokeh lines.
The default bokeh in FStorm is very nice and smooth. But would love to customize it even further.

Like JDE mentioned above, lot of lenses have bokeh with thicker and brighter outer border. Some control for this would help.

See here some lenses produce this effect like the Nikon 105mm DC Nikkor. http://www.4photos.de/test/Soap-Bubb...eh-Lenses.html

Thank you!

Thank you!

You have to reproduce proper conditions for good bokeh
Here is my test

[Raziel]

Hi Karba, thanks for the cool test image. I have absolutely no doubt that FStorm has the most beautiful bokeh I've ever came across. FStorm bokeh is perfect but not every lens is this much perfect, so some control might give us to customize the feel of the OOF area.
If you look closer on the Corona image, you can see the use of a custom map has created a different effect for the OOF lines. The center is more transparent and the edges are more opaque and sharp, which gives it a
brush stroke like effect on the bokeh.


Now FStorm OOF area is perfectly smooth that simulate a 100% perfect lens. But as an artist it would be cool if we get some control to tweak that area, to slightly emphasize the oof lines, to simulate a different lens rendering feel. Here I am not forcing you to implement this asap but just letting you know that different lenses create different rendering of the OOF area. We know you are already doing so much as a single guy.

Also these are few photographs I shot that shows the effects.

is there something new about a custom bokeh effect?
