Hello all.

This is my latest rendering for a client who specializes in custom kitchen design. It's not perfect but created as such to convey the intended design. 

I believe that some feedback may include suggestions about only using natural light. However, in order to have all the details well represented and visible, some artificial lighting is a necessary. Lighting is also an important part of the design and therefore must be shown in place.

Hello -
Nice render. Natural light is for sure important. But in the real life, you need artificial light if you dont have big openings. So i think it is ok.
On my opinion, the mirror effect is too strong. I never seen a so polished material in a kitchen.
The overall result is pretty good.

Thanks for the nice comment. Check out the other photo of an actual project I just posted. This finish is a specialty true mirror finish applied to metal. Cool huh? Full disclosure, neither of these are my own design. I only do the renderings.

The lighting is all wrong I'm afraid.

If you look at the top of those tall cabinets, you will see shadow on the ceiling. This is caused by light sources at low level - far lower than from the suspended lights.

This has completely blown out all the indirect lighting. If you wanted to see the effect of the artificial lighting, you can see hat there are too many downlighters. SOme are lighting the top edge of the cupboards which are creating shadow...

Your entire scene is over-lit. It's like a jeweller's shop.

You need to remove all your fill lighting if you want realistic results.

I hear what you're saying and I appreciate the feedback but I do disagree just a bit. I think spaces look too dark without additional lighting. This said however, my goal is not necessarily true realism but rather to represent the intended design.

See this other attachment. I will admit in advance (as I did this one a long time ago) that my meterials could have had better properties such as reflections. However, the lighting issues you describe does actually exist in reality. See how there are dark spaces above the cabinets in the photo too. The rendering was completed well before the actual kitchen was installed.

It's not just that the scene is over-lit, destroying the global illumination - it's that the lighting is actually wrong.
By this I mean that there is light apparently coming from places where there are no visible light sources.

We can have a discussion about the level of illumination separately, but in terms of what looks accurate (and not weird) you have some work to do.

I can sit back and not debate the lighting issues, but chances are that you will keep on making the same mistakes (and these are actually mistakes) and you won't improve the quality of your renders [smile]

The render you have uploaded for feedback, is, to put it bluntly - in technical terms, not very good. The reason for this is that the lighting is unrealistic, which is destroying the ambience. If you just want to show the design, you can use SketchUp. If you just want to show lights, you can use LightUp.

Podium is for producing high quality images quickly - with minimal effort.

The tricky thing here, is that you've actually done more than you need, to get good results! You've added fill lighting when you don't need to. It's actually easier than you have made it.

Turn shadows on in SU, leave your light fixtures as they are, remove all fill lights, choose the interior preset and render. If it's too dark - use the interior brighter presets. They are for boosting the lighting for interior renders. If you want your images brighter still, do it in PIE.

The only fill lighting that works effectively, is invisible LEMs (make sure you uncheck the 'Cast Shadows' box for the LEM material) either behind the camera to simulate a camera flash, or in the windows to boost the ambient light. These should be fairly large, and low power. You can also use them to simulate light bouncing from other rooms outside the camera view.

In any scene, the primary light source should be clearly identified. In the day, unless your windows are small or the room is very deep, that light source is going to be the sun, whether it's direct or indirect. Lights during the day don't add that much when the natural lighting levels are good enough.
