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 :)
whats the sculpture? is there a picture?
To what looks like the first question a foundation for pop music is to have a strong bace, then add some treble and vocals. If I personally was making a self portrait I would use purple brown and my skin color. I chose purple because its my favorite color and I like to dye my hair it. I chose brown because its the color of my roots and eyes. And obviously the color of my skin because well it would probably look weird without skin lol. I think the dark colors may make it look a bit depressing but oh well. A chef needs serten tools to cook like knifes, pans and measuring utensils, like cups and tablespoons/teaspoons. Sadly I can't answer the last two. Hope the other answers helped though.
