It depends on the size of the hole in the pinhole camera.
If the hole is small, less ray light will flow through the gap. Therefore the image
will naturally be dimmer. Not only that but it is sharper as the hole is smaller, as
well.

The image from a pinhole camera can in fact be very very sharp, in theory the smaller the hole the sharper the image. Remember though that the amount of light reaching the film in the camera is less and less as the hole gets smaller and smaller. This means that either the exposure time has to be increased (greater likelihood of blurring due to motion) or that the film speed has to be increased. Faster film offers poorer resolution and makes for a grainier image.
Furthermore it is difficult to make a very small hole with sharp edges, this is important because the thinner the beam of light admitted into the camera becomes the more important the precision of the hole becomes.
Predigital photographers tended to use small apertures (stops) to get sharp pictures. Just think of Ansell Adams, who used stop 1/32 to make those amazing photographs of the American landscape.
Each single ray of light that reflects from a single point on an object does so in an infinite number of directions. The job of a lens is to gather and focus as many of these rays, which have slightly different angles of incidence, as possible. Since there is no lens in a pinhole camera, the method of control is to allow only a few of the rays from a single point that are close in angles of incidence to pass and land close together on the image plane. This can only be done by using a small opening.
The opposite of sharp (able to cut) is dull.The opposite of sharp (pointed) is blunt.The opposite of sharp (perceptive) is dull, dim, or obtuse.The opposite of sharp (cheese) is mild.The opposite word for sharp is "dull".
Slow, quick, sharp, dull, dry, acerbic, caustic, dim...

boring, dim, dumb, repetitive, dreary, stupid, tiresome, or tedious. Those are all opposites of dull.
This iris diaphragm of a microscope contains the amount of light that can enter through to the specimen. If the condenser iris diaphragm is open, the image will be bright; if it is closed, it will be dim.
TigerDirect.com has 8 MP cameras for $69.99. Note: the MP count of a camera means much less than the other features on the camera. In fact, in small inexpensive cameras, high MP counts can mean poor photos in dim light conditions.
When you look straight at an object, the image is focused on the fovea, where the receptor cells are all cones. These cannot respond to dim light. If you look to one side, the image is focused elsewhere on the retina, Where there are more rods, which are sensitive to dim light,
With camera's using flashes the benefit of this allows a picture to be captured in darkness. The camera flash allows a dim/dark dusky room to be illuminated and all the precious moment to be captured. With the camera flash capturing the image and reflecting it onto the film in older cameras this was the basis to a picture. But now with digital camera's it allows us to get a brighter room.
Light travels around the Earth 7 times per second. This light bounces between your eyes and the mirror in a bright place to produce an image. The shinier and undamaged the mirror is and the more light there is, the clearer the image will be. That's why it's harder to see an image in a dim room, or on a cheap/scratched mirror.
