Nice soft light image (how to)

I noticed these renderings and I was wondering how to achieve a similar effect in Vray, if that is possible. I mean especially those soft light rays wich resembles a lot real light.

just change the softness on the shadows. then do a lot of post effect blooms to soften the entire image

NIK color EFEX
or
MAGIC BULLET LOOKS

these two plugins will help you very well

I was thinking to some kind of frosted glass put in front of the lights originally, anyway, thanks for your tips. I will try that.

YOu don’t want to put frosted glass in front of your lights, that will increase noise/render times and not do anything for you that using area lights won’t.

The point of the frosted glass in real world application is to generate a larger light source from a smaller one, and to diffuse/scatter the light a bit more - both of which you will get already with a Vray light set to plane mode. The Vraylight will render much faster though.

In Photoshop:

-make a flattened duplicate of the final image on a new layer
-desaturate the duplicate
-gaussian blur the duplicate with a medium to high value
-play with the blending of the duplicate layer (‘soft light’ and ‘overlay’ usually give good effects for this purpose)
-adjust the opacity of the new layer to fine tune the effect

As stated above, you will need to blur the edges of your shadows to match the image example that you have shown, but the above method will give a decent bloom effect even without doing this as long as you have good contrast in an image.

Probably worth mentioning that you need to increase the size multiplier of your VRaySun, if you’re using one, to soften the area shadows…
Larger the size, softer the shadows..

Thanks, I recreated the effect mainly with the photoshop tip, as suggested by Beestee.
