Blender newbie here. I recently finished the donut tutorial (I know, I know, but its actually helped me a lot). I'm trying to follow the tutorial again, but with my own object (a cupcake). I'm having some problems with the light, I've deleted it multiple times and tried again but its still super bright. There is also no shadow on the plane. Does anyone know how I can fix this? Thought I'd try here before redoing it. Thanks
The main problem here is not only the distance from the cupcake, but also the size. The Watt values for lights are trying to recreate realistic lighting which means, the size of things matters a lot, too.
Your cupcake has a diameter of about 0.016 m, that's just 1.6 cm which is quite small. So you have a very tiny cupcake with a light source very close to it. So this is how the render looks on my computer:
But if I take all objects including the camera and scale them by 5, so that they all get bigger while remaining in the same relation to each other, suddenly the 1 W light isn't so bright anymore. It is still very close to the cupcake, though. The cupcake is now 8 cm in diameter, maybe a bit too large now but you get the idea:
That's why one of the tips which Blenderguru Andrew always gives for realistic renders is: use real world dimensions.
