it looks strange, if there was that much light probaply my eyes or cam would only see white.
And if there was less light, then the wall behind the lamp should catch more shadow ?
Have you tried to get similair effects using in blender ?, perhaps use mesh light ?.
(asuming your good at light i dont know you skills in this area).
the first 2 images are just from the 3D view and only the 3rd is an actual rendering. Area lights in Blender cannot cast shadows and this is a pretty handy tool when setting up a scene and getting a rough idea about falloff and shadows before you even start rendering.
Doesn’t the cycles preview in viewport make up for that a bit, though? being able to see what the shadows will actually look like is a bit better in my book than turning it into a point lamp.
yeah - I found the cycles material preview not very usable for many things because it does not render much. for example if it would pre-render a texture based on the procedural nodes it would be more useful. Pixels3D did that back in 2000.
