Also, the bright area in the back is very important. It looks like a wall that's getting a lot of sunlight through a window. This creates a lot of reflections that reach all the way into place where the camera is. You can use a sunlight to create that hotspot, but make sure the walls are blocking the light in other places.

Diffused lighting examples

I have been trying to create "diffused" lighting in my scene. Here is the picture i am trying to recreate and attached is the blender scene with the appropriate camera / view. I have tried making my materials more rugid, i have also tried to use musgrave + noise textures to diffuse the light but i always get the very sharp sun shadows ? Maybe the glass i use should act as a "diffuser" ? but i have no clue as to how to do it ? or maybe instead of a sun use a big ball of light ?

Diffused lighting interior design

The sun lamp source will always cast a hard shadow because of what it's modeled after. The sun. The sun creates a hard shadow in the real world because if you look at it in the sky, it's quite small. It's more like a single light bulb. When creating a diffused light, avoid the sun lamp at all times. use environment textures instead, and use area lights on the walls to mimic/augment the reflections that are coming from the white walls. This way The whole scene will be lit instead of having all shadows be pitch black.

All methods to prevent stray light create sharper edges richer in contrast in transmitted light as partial shade effects as edge fringes disappear in this way:

Indoordiffuse lights

Particularly transparent and semi-transparent objects are screened in transmitted light, there is hardly any contrast and the objects are difficult to evaluate. Due to the smaller wavelength, short-wave light strays to a greater extent than longer-wave light. In this case, the use of blue instead of red light produced more than 10 per cent additional contrast.

The component itself is only recognisable as a silhouette, no statement can be made about the surface of the part. The area surrounding the object is the illumination into which the camera system looks. Because of this massively excessive light, the entire application is relatively resistant to stray light.

By using a polarizing filter on backlight and optics, the test object can be partially darkened by means of the effect of photoelasticity in case of transparent, hard plastics. Particularly highly transparent materials hardly generate any contrast in transmitted light, which is required to find the object or edges. This technique serves to increase the contrast and enhance an evaluation.

Leddiffuse lights

Transmitted light illumination is the first choice of lighting when it is necessary to measure parts as accurately as possible. The lighting is arranged on the opposite side of the camera, the component itself is put in the light beam.

Interior scenes are difficult to properly light due to the amount of light bounces that Blender needs to calculate. Try to be creative using these 'artificial' lighting techniques until it looks right.
