Here is the best way I can show you... PLease excuse my Typo's, the first # represents the F-stop, the second # the shutter speed. All of these were taken with a tripod, a 70-200 f2.8 lens, and my 500D close-up filter. THe filter REALLY exxagerates the depth of field, so it made the examples even easy to tell apart. I will start with the smallest apeture, and work my way to the largest. So f32 first, f 2.8 last...












Hope this helps.... Next I will show Noise and ISO...

Oh man that is an excellent visual representation Mike. So here what we have is the lower the F-Stop with Higher S, the less out of focus the entire picture becomes.

*Mental Note For Scott:
When shooting in manual go for high F and low S.

And use tripod... At the largest f# the aperture is the smallest and will need lots of time to have enough light to pass through it to the sensor, so I don't know who can hold camera still for this long... Can you, Mike?

PS. Nice visual, Mike. I think I never shoot anymore with less than f8, all you see is a small dot in focus if you use 3.5 on my macro lens.

Got it!

Hehe...

I can hand hold down to 1/15 SOMETIMES... depending on which lens, and what focal length...

Scott that trick only works for pictures of corals, a fast moving fish will kill your "high f and low s" mental note...

Unless he's extremely good at panning
