suite - by Warren Young. f/Calc is a calculator for photographic formulas.
These formulas are at the heart of many interesting questions about
the technical side of photography. You could compute these functions
by hand, but they range from tedious to difficult, even with a good
scientific calculator. When you let f/Calc do the hard work, you gain
an intuitive feel for what the results mean, because you can quickly
try new input values to see how they affect the result. The Windows,
Macintosh and Tcl/Tk versions of f/Calc are free software, licensed
under the GNU General Public License. The Palm OS version is shareware.
It has dof; hyperfocal distance; angle of view; spotmeter angle; magnification!
Great tool set!
- Pocket PC Freeware by Jonathan Sachs. Exposure 1.0 is an automated
exposure guide for photographers that computes recommended exposures
given film speed, filter being used, type of film, and scene illumination
level. It can operate in either aperture or shutter priority mode and
it incorporates a knowledge of the proper exposure for many different
lighting situations, including corrections for filters and film reciprocity
failure. The filter, film and scene databases are customizable.
Other tools: Stoptime

1.0 - Pocket PC Freeware by Jonathan Sachs. Dof 1.0 is a program
for photographers that computes depth of field of lens given its focal
length, f stop, resolution and focus distance.
It reports the near and far focus limits and the hyperfocal distance
(the minimum distance you can focus at and still keep infinity in

ultimate exposure computer is not a computer at all, nor a program,
but a very usefull chart and a very long manual. By Fred Parker.
Calculator - Robert E. Barrett. Based on Fred Parker's chart: this
Calculator will, for the given light conditions and film speed, calculate
the appropriate camera settings to yield a correct exposure.

in the best sense). Sehr sehr komplett. Wirklich alles ist drin. Zerstreuungskreis

you understand a little bit of German this is the last DOF and Close-up
calculator you'll ever need. Is this one complete! Calculates just about
everything and discusses all the major choices. This one is from the
people that make the german photography newsgroup probably the best
on the net. My personal favourite.
of confusion calculator - Don Fleming. If you want to use depth
of field calculators with your digital camera, here is a list of camera's
and a calculator. It is the calculator used in Don's DOFMaster
program (see below). Some good articles about depth of field theory
and dof-equations are here too.
- online depth of field calculator - Don Fleming. A very basic online
calculator, BUT his free downloadable DOFmaster
for Windows and DOFmaster
LE for Palm OS are excellent. DOFmaster allows you to print scales
for any format, in the old round Kodak paper calculator style. They
even fit on your lenscap! Neat.
of Field is another free download from Digital Light and Color.
- Simon Walton. Java. Also as a free download. 16mm and 35mm only, because
it is intended for use in motion-picture cinematography. It can calculate
the depth-of-field given the focus distance and lens settings, or the
required focus distance and f-stop for a given depth-of-field. It also
calculates hyperfocal distances. Where is it? Has Simon vanished?
- Nicholas V. Sushkin. Nice plots. Good, simple and very useful.
Calculator - Michael C. Gillett at the site of Bob Atkins, who
wrote a good and comprehensive article explaining it. Werkt ook in
Decimal too. Atkins has some very useful discussions and charts on
MTF and diffraction.
calculator - J. Dudak. Very extensive. Calculate depth of field
or find the f/stop and focusing distance needed to keep a known near
and far distance sharp with this depth-of-field calculator. You can
also compare up to five different settings or lenses at a time.

Brian Chandler. A collection of articles

is a close-up filter? - I got so annoyed by people using the term "close-up
filter" I wrote this. Includes the basic stuff about a lens (1/u
+ 1/v = 1/f), and calculators for this and lens combination.
Yes, but this is OK for simple lenses in the school
physics lab. A real camera lens isn't thin, and it costs lots of money:
surely the same rules don't apply? Real
lenses are more complicated Well,
money rarely buys exemption from the laws of nature. This
guy is funny!
He lives in Japan (160 km from Mt Fuji) and reveals the correct

Another useful one: Adjusting exposure for teleconverters and extension
distance calculator - M. Baltuch. This is a java applet that calculates
the hyperfocal distance for a given film format, focal length and f-stop
combination. The Hyper Focal Distance is the focus point, such that
anything between half the distance to the focus point and infinity
in focus. From this page you can also download a Hyperfocal Distance
Chart for 35mm lenses. The chart is sized so that you can print it
laminate it and it will fit neatly into a camera bag.

JavaCam of ArtKids allows you to view a scene via the the camera's
viewfinder and lets you take a picture. You have control over the exposure
by adjusting the camera's shutter speed and lens aperture controls
manual mode). Alternately, you could set the camera to one of its auto
modes (shutter priority or aperture priority) and see how the camera
sets the exposure.
And this is for children? Wow! Great simcam! The best for free.

Optical Design Software OSLO is software used by scientists and
engineers to design lenses, reflectors, optical instruments, laser collimators,
and illumination systems. It is also used for simulation and analysis
of optical systems using both geometrical and physical optics. In addition
to optical design and analysis, OSLO provides a complete technical software
development system including interactive graphics, math, and database
libraries. There is a free version of OSLO intended for educational
stands for Optics Software for Layout and Optimization of optical systems.
OSLO is used primarily to determine the optimum sizes and shapes of
the elements in optical systems in cameras, consumer products, communications
systems, military/space applications, scientific instruments, etc. In
addition, it is used to simulate the performance of optical systems,
and to develop specialized software tools for optical design, testing,
