The future or something that happened to them
3. Some challenges to photographing children are that a large percentage of kids are very antsy and are hard to keep still and pose. You can reduce these problems by maybe playing some relaxing music or promise them a reward afterwards.
4. Challenges for photographing groups are that, large amounts of people are hard to cooperate with at once. You can reduce this by working with a small group of people at a time, telling them how you want them to act, pose, etc. until you talked to the entire group.
5. Three tips for photographing children are: play some music, promise them a reward for cooperating, or consult them (reassure them it will be fun)
Exposure means how light or dark the image you took with your camera will come out which is determined by the exposure triangle which contain 3 camera settings(aperture, iso, and shutter speed)
as aperture increases the f-stop values, the lens shuts. as it decreases the lens opens
light is a factor in the exposure of the photograph. aperture must be calibrated so the image will be clear and focused
I'm not sure on the last one but I know that when the aperture is low itll be a fast lens and when its higher itl be a slow lens
I hope I helped :)
