I realized, that giving your scene enough daylight, shows up the beauty and power of Corona.
Working with no or almost no daylight- changes the overall look & feel.

I tried to use corona disc light and use a longer exposure with my camera- to fill the space with light.
As a result the wooden brown floor colored the overall look & feel into a 70"s looking image :-) 

Does anybody experience the same and what are the rules for superb realistic images ?

happy day..

Come on, not a single picture to show what you're talking about? I can asure you that Corona is perfectly capable of rendering stuning interiors with artificial lighting. Just visit the gallery and see for yourself: https://corona-renderer.com/gallery

So you are basically saying that an image with daylight looks different than an image with no daylight, right? :)

Seriously, are you expecting to get an answer to this in a single forum post?

There are various factors that affect the realism of rendering. Such as high quality textures, correctly set up materials, realistic differences between intensities of different light sources, camera exposure, post-processing, models,... There are courses about this, some of them take longer than one month. There are books about this, too.
Some good starting points include:
 - Observing the works of the "masters"
 - Observing real photographs and using them as reference for your 3D artwork - compare the composition, dark vs bright areas, colors, textures,...
 - Mastering your tools. If you choose Corona, for this you can visit our helpdesk and watch our YT tutorials:

Hi guys,

Thanks for your replies. Maybe my communication wasn`t good. Sorry.

I think that daylight interior images are easier to achieve in a realistic quality than working only with artifical lights...

So I was wondering how to deal with corona light settings, as well as the overall light situation....

Attached are two images- where I try to explain my problems...

Thanks !

If you see those two images from the gallery.

I know it is stupid to compare two images like that- but i shows how good the "feeling of daylight" the bedroom scene is compared to the
more artifcial litten scene.....with less reality.....

Just use the Coronarayswitch material.  This will allow you to directly show the wood texture, but use a separate material to generate your gi contribution.  It will help control the color bleed.

You compare soft natural light probably coming from big light source to light with single small spots...Not to mention that most of the objects in the artificial light reference interiors are hard-surface objects, whereas the other ones have some soft materials.
Two very different light scenarios.
 You can mimick the soft look from the artificial light by using  for instance softbox concept with non-renderable light bouncing objects when using artificial lights in conjunction with spot lights. You can then play with light intensity and color of the objects used for bouncing.
