Optics/photography question!!!! What is the technical term for this........................................?

Question

the distance between closest and most distant point in focus in a three-dimensional image:

Answer 1

it is the focal plane, or depth of field; which is related to the aperture. The larger the aperture (lower f-stop number), the smaller the depth of field/focal plane area (less three-dimensional area that is in focus, which will cause foreground and background to be blurry). Smaller apertures (larger f-stop numbers) have greater three-dimensional areas that are in focus.

Hope this helps.

Answer 2

Don't know about 3-D imaging, but in 2-D imaging, you're talking about "depth of field".
I would assume the same basic function would be called by the same term. I'm actually certain of it.
And-- just in case you are not aware-- depth of field is increased by stopping down the lens aperture (like from 4.5 to 5.6 or 4.5 to 8, assuming (this is 2-D, now) your shutter speed doesn't change. Fortunately, if you're looking through your viewfinder (SLR) as you change your aperature setting, the depth of field is very visibly obvious.
I hope that helps.

BYB is a thank you to tell apart those people from severe breeders. BYBs are in basic terms doing it for the money. they do no longer take good care of the doggies or the mum. they gained't get vaccines performed. they gained't feed the right food plan. They breed as in many circumstances as they might and sell the doggies to every person who will provide them the money. severe breeders care approximately their canines. They make useful mom and the dad are in quite good well being in the past breeding. they are going to in basic terms breed, at maximum, as quickly as a year. They take the doggies in for checkups and vaccinations. they only sell whilst they have had a huge gamble to question the purchasers and communicate in regards to the seriousness of possessing a puppy.

quite complicated best check out a website

Answer 7

Yes, definately depth of field. Is subjective (I.E. "Acceptable" focus). Also, there's a way of pre-setting it from a particular point to infinity, is called hyperfocal distance. Dunno if that helps (look it up!)

Answer 8

depth of field

Answer 9

What in the world are you talking about?
