Hi all together,

some years ago, I've started the project of creating a a
depth-of-field calculator in form of a disc.
But I somewhat forgot about it, too many other things to do.
Now, after some rainy weekends, I finally managed to finish the first
version.

A number of discs are available for different circles of confusion,
each covering the (approximate) focal length range of 28 to 105mm (or
the equivalent for that equipment) as well as f-stops from about 2.8
to 22.

I've made it publicly available under the following URLs. Each PDF is
about 1.2 megs in size. There is a German (metric) version and a US/UK
(imperial) version:
http://www.silverimages.de/downloads/dof-metric.pdf
http://www.silverimages.de/downloads/dof-imperial.pdf

I'd like to know if this is useful for others and of course your
comments for improval.

Please send comments also as PM, since I'm no regular reader of US/UK
photo groups, I usually only read the German spoken de.rec.fotografie.

Best regards,
Jens.

You might want to consider a metric (UK) version, as the UK has been
metric since about 1970.

1) An english metric version would be welcome. Not all english speaking
countries have retained the imperial system.

2) While what you did is nicely done, I find it is simply easier to use fcalc.
(Which is also available in a clumsy application for Palm Pilots ... that I
don't use).

Cheers,
Alan

er, last time I was there (2002) the speed limits were in MPH. While Canada
migrated to metric (beginning in the 70's) at a seemingly slow pace, it was
blindingly fast compared to the UK.

They still are (not that anyone pays much attention to them <g>) but
petrol is sold in litres, beer in pints and fruit in kilos. It's a right
mucking fuddle.

Out here in the antipodes we've been metricated for decades ...

And then I went to the Co-Op to buy 12 oz cheddar to find that the
woman behind the counter thought it was a strange US measurement
as she was Canadian. I must admit I don't buy cheese this way
often and usually get blank looks when I ask for it in ounces, but
why can't they sell it in ounces. Provided prices are per kilogramme
and you can buy it per kilogramme what is the legal problem when a
customer asks for it in kilos?

A couple of dozen years?

At least all talk of making us drive on the other size of the road
has died as obviously impractical and expensive.

They will get around to that in the UK sooner or later - except as things
usually go in Britain - they will want to have the ordinary motorist make
the change-over to driving on the other side on one day, and commercial
lories and busses on another.

Good point. What paper size is common in the UK?
The German version is on "A4" and the English/imperial version is on
"US Letter".

After all, the difference concerning the discs is minor, the big
difference is the instruction page.
