it´s not a big thing. I tried to integrate some concrete-balls into a background image. I was getting weird with the shadows and the lightning. Tried to do it as photorealistic as possible.
Shadows are a bit heavy for the scene. Maybe try decreasing the lightsource intensity a bit. but the main issue for me is the blurry background shot. Snapped by a mobile by any chance? Balls would need a bit more blur, and probably some noise to fit. If it was me, I’d be looking for a better background image, unless blurry mobile shot is the look you’re going for. Even then, it’s better to start HQ then downgrade in post.
Yes it is all done in Blender. I am practising for a projekt. i have some very high resolution pics (20k) from mars surface and i want to render some objets in.
