The sharpness of a shadow is reduced by two source: diffraction of light around the body and secondary light sources. Diffraction is a physical phenomenon, so unless you make something without edges (hence no shadow) you're not gonna get rid of that. So try to pick a very dark area where the only light source is from what is making the shadow. Eliminate reflected light from that light source. And I would say try to get the light rays as close to parallel as possible. This means be far from the light source. Ideal situation:
I shaft of light from the sun penetrates through a skylight in the ground (say the roof of a building that has all of it's windows painted over). Put an object in that shaft of light (inside the building) and the shadow should be as sharp as you're ever gonna get it. Parallel light, no reflected light sources--that's about it.

What is umbral shadow?
Umbral shadow refers to the darkest part of a shadow, where no direct light can reach. It is the region that is fully obscured from light sources, resulting in complete darkness.
How do you make a darker shadow?
The number of shadows that one person casts depends upon the number of light sources shining on the person. If one light source hits the person, they will have one shadow. If there are two light sources, then the person will have two distinct shadows, as well as places where the two shadows overlap. The will continue.
Does light produce heat?
Yes, light does produce heat. When light is absorbed by an object, the energy from the light is converted into heat, which can raise the temperature of the object. This is why objects can feel warm when exposed to sunlight or other sources of light.
What does not make a dark shadow?
Transparent or translucent objects do not cast a dark shadow because light can pass through them easily, preventing the formation of a clearly defined shadow. Materials like glass or clear plastic will not produce a dark shadow when exposed to light.
Why does foil paper shine in the dark?
Foil paper appears shiny in the dark because it reflects the light from other sources, such as ambient light or artificial light nearby. It does not produce its own light.
What produce the sharpest reflection?
It is most likely silver or gold as their shiny and if light shines down,the reflection will be the sharpest Adapted from my brain LOL-_-
Can an object have more than 1 shadow?
Yes, an object can have more than one shadow if there are multiple light sources casting different shadows from different angles. Each light source will produce its own distinct shadow.
Does a flame have a shadow?
No, a flame does not have a shadow because it emits light and does not block light from other sources.
Does intensity of light cause darker shadows?
Yes, the intensity of light can affect the darkness of shadows. Higher light intensity can create darker shadows, while lower light intensity can create lighter shadows. This is because stronger light sources produce more defined shadow edges and a greater contrast between light and shadow.
What is umbral shadow?
Umbral shadow refers to the darkest part of a shadow, where no direct light can reach. It is the region that is fully obscured from light sources, resulting in complete darkness.
What is the difference between natural and artificial light sources?
Natural light sources, like the sun, produce light through natural processes, while artificial light sources, like light bulbs, are man-made and produce light through electricity.
Does a mirror make a faint shadow?
No, a mirror does not produce a shadow because it reflects light rather than absorbing it.
Can your shadow be reflected in the mirror?
No, your shadow cannot be reflected in a mirror. A mirror can only reflect light that is directly shone on it, whereas a shadow is an absence of light being cast by an object blocking light sources.
How do you produce light?
We are not sources of light so we do not give off light.Light is given off by sources such as the Sun and Stars.Things that are not light sources reflect light into our eyes so we can see them.
Do all light sources produce heat?
No, not all light sources produce heat. Some light sources, such as LEDs, produce very little heat because they are highly efficient at converting electricity into light. However, incandescent bulbs and halogen bulbs do produce heat as a byproduct of producing light.
Can an object cause more than 1 shadow?
Yes, if multiple light sources are shining on it, then there will be multiple shadows.
What light sources produce UV rays?
The Sun.
