DOF

Uploaded: May 24, 2013

Description

600 mm f: 11 Focus Distance 50 Feet =
Total Depth of Field .72 Feet or
8 5/8 Inches of Focus

In optics, particularly as it relates to film and photography, depth of field (DOF) is the distance between the nearest and farthest objects in a scene that appear acceptably sharp in an image. Although a lens can precisely focus at only one distance at a time, the decrease in sharpness is gradual on each side of the focused distance, so that within the DOF, the unsharpness is imperceptible under normal viewing conditions.

I loved your description of DOF...almost poetic. Not many of us (including me) could actually define depth of field.

Oh, and by the way, the photo is beautiful. #10706468

Ooo! What a great class in DOF today! Thank you! I knew what it was but had no idea how to say it!

This is a beautiful image Wm! I LOVE YOUR DOF! (HA!)

Did you get my e-mail with the download link in it or making your Windows 8 experience great to use? Check your e-mails from Lydia it's in there! The link is there in that mail for you for the shell to upgrade windows 8 and it's free! I sent you a BP mail on it, too! :) I thought it was $30.00 or more but was wrong. It will make your windows 8 like windows 7! I promise! :D

Great job here!!!
