You can use shadows to measure the heights of trees, or buildings, as long as you can make two separate measurements at exactly the same time of day. While one person or group measures the length of the shadow of the tree or other object, another person or group carefully measures the length of the shadow cast by a smaller object, such as a person, sign, or pole.
The ratio of the length of the shadow to the height of the object will be the same for almost every object casting a shadow at that particular moment of the day. So divide the known or measured height of a person by the length of his shadow to find this ratio, then multiply the other shadow length by this amount, to give a good estimate of the height of the taller object.
Example:
A tree's shadow at 5 PM is found to stretch 80 feet from the base of the tree.
A boy is known to be 5 feet tall, his shadow at 5 PM is 10 feet long.
(So the shadow length of other objects, measured at 5 PM, will all be twice their height.)
5 ft/ 10 ft = 0.5 and 0.5 x 80 = 40 tells us the tree itself is about 40 feet tall.

What are the correct lights for avoiding shadows?
The camera lights are not the only thing that causes shadows. You must also use the correct technique, angles, settings, backgrounds, etc. I have found that you can avoid shadows by having the subject far away from your background and the lights positioned at an angle so it casts the shadows out of the frame seen in the picture.

How can I take a picture with no shadows?
To take a picture with no shadows, use diffused lighting or shoot during overcast conditions to minimize harsh shadows. Additionally, adjust the angle of the light source or use a reflector to fill in shadows.
How can I capture a picture without any shadows?
To capture a picture without any shadows, use diffused lighting or shoot in evenly lit conditions to minimize shadows. Additionally, avoid direct sunlight and use a flash to fill in any remaining shadows. Adjusting the angle of the light source can also help reduce shadows in the picture.
How can you measure the angle of insolation without being able to see the sun's rays individully?
you can measure the angle of insolation by measuring the angle of the shadows that appear
How can I take photos without shadows?
To take photos without shadows, use diffused lighting or shoot during overcast days to minimize harsh shadows. Position your subject facing the light source to reduce shadows, or use a reflector to bounce light onto the subject. Additionally, editing software can help to further reduce or remove shadows in post-processing.
What literary device does the author use in the words the forest whose purple shadows welcomed him?

How can I achieve photos with no shadows?
To achieve photos with no shadows, use diffused lighting to create even illumination and minimize harsh shadows. Position the light source directly in front of the subject to reduce shadows, or use multiple light sources to evenly light the scene. Additionally, consider using a reflector or diffuser to bounce or soften the light, further reducing shadows in the photo.
How can I take a photo without shadows?
To take a photo without shadows, use diffused lighting or shoot during overcast conditions to minimize harsh shadows. Additionally, adjust the angle of the light source or use a reflector to fill in shadows. Experiment with different techniques to achieve the desired shadow-free effect in your photos.

What did ancient egyptians use shadows for?
erasthenes who lived in Alexandria Egypt but was greek used shadows to measure the circumference of the earth first noting that the sun at noon cast no shadow on statutes then travelling 500 miles away to syrene (libya) and noting the shadows cast a shadow of 7 degrees at noon he then calculated that there was 360 degrees in a circle there for calculated that the earths cicumfrence must be 25 500 miles this was not entirely accurate but a very close
