Before and after focus adjustment

[RiverRunner]

No wounds to lick. and yes I'm busy on a show

Hope you are not using that hyperfocal app Ha Ha. Still waiting for you to show us your results with your camera focused at 9".

We are doing a several shots today using the hyperfocal. It's a shame you don't understand the concept and the physics yet you will try to tell others that you know better

I have already proven it wrong. You won't show your results because you know it does not work. Your app is giving you bad information. There are some good hyperfocal calculators out there and they all disagree with your results.
Come back when you have something to show. Otherwise it's all just blather.

you've proven me wrong? How? and the calculators are come up with the same answer because the equation doesn't change.

Hyper Focal distance =
(The focal length of your lens in millimeters x The focal length of your lens in millimeters) / (Aperture x Circle of Confusion in millimeters) The lens focal length is 3.7mm the aperture is f/2.8 and The CoC is .0216mm or the size of one pixel so it's (3.7 x 3.7) / (2.8 x .0216) 226.28mm or 9"

Hyper Focal distance =

Prove it. Show Your images. It does not work.
Oh now we are down to 4.8"???

No not 4.8 look at my post. You don't get it. It does work we use it everyday, your camera phone uses it.

You have no idea what you are talking about and can't understand how it works, we get it. it doesnt make you right.

I'll post them again for you. Look at them full size and tell me that is sharp in the distance.
Focused at 9"

Here is an online depth of field calculator. Plug in your 9" number and you get a whopping 5 inches of depth. I suppose they are wrong too.

 

[Rayray]

You happen to be one of them.

Oh my, how ungrateful. Must I remind you of my Doctorates in Metaphysics and Parapsychology? He who casts stones is doomed to become one.

A Flexible Depth of Field Calculator
This is the hyperfocal distance calculated by this website. The first is based on an 8 x 10 print viewed at 25 cm and .01" CoC.
The second is more realistic for our purposes and is based on 20/20 vision.

Hey, thanks for that link; sure beats seat of the pants method.

I prefer to actually test things myself. With digital media., it is easy to take a few shots and check them for sharpness. The problem with using any app or formula is what you define as sharp. Their standard of .01" for CoC would mean the circle covers 4 pixels wide and 4 high on a 12 Mp image. That is not sharp when you look at the full size image on a monitor or view a 4K video on a 55" screen. I prefer to set my focus distance inside the range of distance I need to be sharp. I don't care if it is a bit unsharp at 4 feet. I will not be flying that close to something.
I am very happy now with the images and videos from my H. It was just focused too close. (Maybe they were using the same app as Der Stig. Ha Ha .)

 

[DerStig]

Only I don't use .01" for the CoC my calcs are using pixel pitch. Once again you're not understanding the information presented

 

[RiverRunner]

Just talk. Still waiting for images.

Did you apply sharpening to this or is it just the way the forum is showing it?

There is some sharpening applied during development from dng file, but not as much as you get with gorgeous mode.

looks good!

That would be more than 13 pixels!
The 1/2.3 sensor is 6.16 mm wide. Divide that by 4000 pixels and your pitch should be.0015.
