I hope your not suggesting that film photography cannot photograph something red?
Perhaps the special "red light" used in developing rooms are of such a wavelength that the photographic dyes are not sensitive to.
Thus, I think this has more to do with wavelength sensitivity rather than "energy" levels.
Just my thoughts... could be wrong.

Light momentum is the measure of the amount of energy carried by a beam of light. In photography, it refers to how light particles interact with the camera's sensor to create an image. The momentum of light affects the quality and clarity of the image captured.
2.Light travels in a straight line and at a constant speed of approximately 186,000 miles per second. This is important in photography because it determines how light will interact with the camera's sensor and how it will be captured in an image.
3.The three main types of light in photography are natural light, artificial light, and flash. Natural light is the light that comes from the sun and is often considered the most flattering for photography. Artificial light refers to any light source that is not natural, such as light bulbs or streetlights. Flash, also known as strobe light, is a short burst of intense light used to illuminate a scene or subject.
4.Light plays a crucial role in determining the color of an image. The color of light itself has a temperature, measured in Kelvin, which can affect the overall tone of an image. Additionally, the quality and direction of light can also impact the color of a photograph, creating highlights, shadows, and contrast.
5.One tip for using light effectively in photography is to pay attention to the direction of light. Side lighting can create depth and texture in an image, while back lighting can create silhouettes. Another tip is to use diffusers or reflectors to soften or redirect light for a more flattering effect. Additionally, understanding the color temperature of light can help in creating a desired mood or atmosphere in a photograph.
