DOFMaster Depth Of Field Calculator

Hi I don't know if anyone would find this app useful, just thought I would put it here, hope you didn't mind. Thanks.

It has been mentioned before and I'm sure that a reminder doesn't come amiss.

Hi, It refused to install even in compatibility mode on Windows 8 64 bit.

I find their online DOF calculator to be much more useful, you can even use it in the field with your tablet or smartphone.

I had never heard of it before

I use the DOFMaster app on my iPhone and find it pretty useful for discovering the hyperfocal distance when I want to get max depth. I imagine at heart that it's a pretty straightforward calculator - it would be very cool (I think) if such a thing could be built into the camera software...

Cheers

It used to be built into every lens

I use PHOforPHO on my SamsungGalsxy II. It provides a hyperfocal calcualtor, a DOF calculator, EV for multiple exposures (never used it), an exposure calculator for low light exposures, a timer and a distance meter using the GPS. Very handy for when needed.

DSLRs could display the DOF in the read LCD, or even in the viewfinder, for those lenses that report the focal distance to the camera

I'd patent that idea if I were you

Would it be that difficult to, as well as having the Hyperfocal Distance calculator in the camera software, have option that the (AF) lens automatically adjusts itself to the HD when the autofocus button is pressed?

I'm sure I read somewhere about cameras in the film era where you'd focus on your near point and your far point, and the camera would select the focus point and aperture to ensure everything in between was in focus.

Maybe it didn't work too well, as the idea doesn't seem to have caught on.

Be simple if the lens reports the focal distance. Also depends on the accuracy of that reportage.

I remember when I repaired my Sigma 17-70 I noticed copper tracks that were used to record the position fo the focus ring, but it was only 4 bit, meaning 16 steps. IIRC. Could have been 5 bit, 32 steps.

I believe Canon D-SLRs have an "A-DEP" mode that attempts to sort out depth of field. Good idea if it works.

Personally I like the way it used to be done.




Sorry it's a bit blurry, looks like it could do with having the dust wiped off of it too.

That photo shows what nonsense these DOF Calcs are
Look how much you have between 3M and INF
How do you set 20M or 40M on that scale when the total
movement you have is about 6mm ?

Most of the calcs are based on the smallest dots that someone
can see on a 10"x8" B&W print..... but no two people see the same
and nobody has a 10"x8" B&W Monitor these days

It's also been revised at least 3 times and I don't think they
used the latest revision on the lens scales.

With a 28mm or 35mm lens just set it at INF and use f/8
everything from about 2M to INF will be in focus no need
to bother focusing at all and I'm referring
to sharp as sharp enough for pixel peeping not on a
10x8 print.
