The document is intended to inspire travelers on photo subjects and techniques to utilize during their travels.
The document describes the steps taken to design the cover of a magazine promoting a film. Key points:
1) The cover features a half-face image of the film's sister character to engage readers while hinting at mystery.
2) Various editing techniques were used to incorporate images and elements like a shadowy werewolf and blood on the sister's face to convey the horror genre.
3) Feedback ensured the cover successfully portrayed the film as a horror rather than thriller. The completed cover aims to interest fans of monster movies and generate hype for the promoted film.
1) The document describes several simple mirror systems that have unusual optical characteristics despite using few elements.
2) Many of the designs use multiple reflections off of spherical or aspheric surfaces to correct aberrations like astigmatism.
3) Unexpected solutions are found, such as designs that correct third-order spherical aberration using a single reflective surface.
Schmidt's three lens corrector for a spherical mirrorDave Shafer
Schmidt's aspheric plate in a Schmidt telescope design can be replaced by a group of three spherical lenses, as Schmidt himself showed, but he died before he could publish anything on this. Here I show many alternate versions to Schmidt's design.
Nora Ephron was a screenwriter, director, and author who came from a family of screenwriters, with both of her parents being successful Hollywood screenwriters in the 1940s-1950s. She grew up in an unconventional household for the time, with her mother Phoebe not adhering to traditional gender roles and focusing on her career over housework, which influenced Ephron to also pursue a career in writing and filmmaking. Throughout her life and career, Ephron drew inspiration from her family experiences and relationships, often turning personal material into her films, novels, and essays.
Dorothy Parker was a renowned American author, poet, critic and wit known for her caustic wit and sharp observations. She was part of the Algonquin Round Table in New York City in the 1920s, writing theater reviews that gained her fame. Parker struggled with alcoholism, unhappy relationships and financial difficulties for much of her life. She supported numerous progressive causes and left her estate to the NAACP, which continues to hold the rights to her works to this day.
Dennis gabor's catadioptric design and some new variationsDave Shafer
A variety of optical designs are developed and discussed, inspired by Gabor's very simple and largely unknown design. Some are extremely high NA (0.999!!!) with a wide field of view and diffraction-limited correction.

Freeform aspheric telescope with an external pupilDave Shafer
A 4 mirror telescope design with freeform aspherics is described which has a distant external front pupil, for those situations that require this. It is unobscured and has a 10 degree diameter field at f/3.0 on an unvignetted flat image.
The optimum lens design form is found where the number of lenses keeps increasing in different design versions but severe space constraints limit the design configurations.
The document discusses theories about the biblical Ark of the Covenant. It summarizes that the Ark was a portable container described in the Torah as being housed in the Holy of Holies and containing the "Pact" or "Testimony" between God and the Israelites, though some scholars argue it may have contained something else. The document examines ancient Near Eastern influences on the Ark's design and possible functions as a portable throne and military standard. It questions common assumptions about the Ark's contents based on textual details.

1) The document describes a proposed design for an unobscured astronomical camera with a 22 degree field of view and f/2 speed, to be used for a new large telescope in Hawaii.
2) It explores starting with an existing 5-mirror spherical design that was used on space missions, but determines a 3-mirror freeform aspheric design may be better.
3) The document presents an example 3-mirror freeform aspheric design that meets the requirements, with all mirrors tilted and shaped as aspheres to produce an unobscured 22 degree field of view at f/2.
A survey of some unusual telescope designs. One has a 20 meter diameter f/1.0 spherical primary mirror while others are suitable for amateur astronomers to make.
A general lens design method, with a photographic lens exampleDave Shafer
This document outlines a general design method for optical lenses using photographic lens examples:
1. Always start with a monochromatic design using a single glass type to achieve the required performance. Use aspherics temporarily but remove them later.
2. Add color correcting surfaces in a way that minimizes changes to the monochromatic design. Use no more than 3 glass types and minimize color inside the design.
3. The example lens design is walked through step-by-step, starting with a monochromatic BK7 design and improving it using aspherics, then removing aspherics by replacing them with doublet lenses while maintaining performance. Color correction is then addressed.

Tight fit, cramming a lot of information through a small volume 1993Dave Shafer
The document discusses the benefits of exercise for mental health. Regular physical activity can help reduce anxiety and depression and improve mood and cognitive functioning. Exercise causes chemical changes in the brain that may help protect against mental illness and improve symptoms.
Romanticism was an artistic movement from 1775-1850 that featured solitary heroes, strong emotions, and individuals apart from society. It emphasized passion, nature, and feelings over reason. Key characteristics included intense passion in love and anguish, daring acts, and brooding poets apart from normal society. Goethe's 1774 novel The Sorrows of Young Werther popularized these tropes and influenced generations of artists. The movement also drew inspiration from imagined ancient poems like those of Ossian that were actually literary forgeries. Operas like Werther and Romeo and Juliet depicted these romantic ideals through stories of doomed lovers and individuals willing to risk death for love.

Melissa Cruz Santos is a medical photographer. Her photographs are used in medical textbooks and publications to show factual information about medical conditions or procedures. The photos are often not highly controlled, as she is observing real medical scenes and surgeries and cannot control the lighting or environment. Some photos may be in black and white to give an artistic style, but the goal is to represent medical realities accurately rather than be purely artistic. Post-production editing is usually minimal to maintain authenticity.
The document discusses various techniques for effective image composition, including positioning subjects to convey movement or story, simplifying images by removing distracting elements, using the rule of thirds to place subjects off-center, incorporating lines and geometric shapes, balancing color and placement of elements, avoiding mergers that cut off subjects or create distractions, and framing the main subject. It provides examples to illustrate these composition tips and how following or ignoring them can strengthen or weaken an image.

Aberration theory - A spectrum of design techniques for the perplexed - 1986.pdfDave Shafer
This document summarizes the design process for a Double-Gauss lens using aberration theory. It begins with the historical basis of two Gauss doublets back-to-back, then walks through building up a design from first principles using aberration theory. Key steps include: 1) Adding concentric surfaces to cancel astigmatism; 2) Adding an aplanatic/aplanatic shell to introduce Petzval curvature; 3) Adding a concentric/concentric shell to push the system to a telecentric exit pupil. This allows removing the final lens element far from the image. The result is a corrected Double-Gauss design arrived at through theoretical understanding rather than trial-and-error optimization.
The document discusses how early lens design progress was hindered by slow hand calculations and lack of modern materials. It provides examples of simple lens designs that were possible even pre-computer but had limited applications without modern technologies. The document emphasizes that while computers have advanced design capabilities, fundamental design ideas and theories are more important. It provides several examples of innovative lens designs the author developed through conceptual thinking alone. The document cautions against overuse of new technologies like freeform surfaces and metasurfaces without consideration of conventional design alternatives.
1) Snakes played an important religious role in ancient Egypt and were depicted widely in art and iconography. When Moses was in Egypt, snake imagery would have been everywhere.
2) Some scholars propose that the Levite tribe, including Moses and Aaron, may have originated as Egyptian priests who followed Moses out of Egypt and had connections to snake handling and worship. References to snakes in the Bible may relate to this.
3) In the Bible, Moses was instructed by God to make a copper snake idol to cure snakebites, contradicting idol worship bans. This later developed into a snake cult in Jerusalem until being destroyed centuries later. Ancient Near Eastern snake cults and worship were common.
1) Optical design techniques include investigating multiple versions of simple designs to find the best one, as different versions can have tradeoffs in higher-order aberrations.
2) Stop shift theory is a useful technique for creating new designs by finding aperture stop positions that correct specific aberrations, such as lateral color, even if the final stop position is constrained.
3) Combining simple optical systems with useful properties, such as common axial color cancellation, is a way to develop new complex corrected designs like the CMO (catadioptric, mirror, objective) type.
Georgia O'Keeffe was an American artist known for her paintings of flowers, landscapes, and cityscapes. She pioneered abstract painting in the early 20th century, creating non-representational works using only shapes, colors, and forms as early as 1915. Her early abstract paintings were prominently displayed by her husband Arthur Stieglitz at his 291 gallery, exposing the American public to this new style of art. O'Keeffe was influenced by Arthur Wesley Dow's principles of composition and abstraction, and she credited Arthur Dove as having the most significant impact on her development as a young artist moving her style towards abstraction.
Frederic Mistral wrote a long love poem called "Mireille" about his native region of Provence, describing its traditions, culture, and dialects. Charles Gounod later adapted this poem into his 1864 opera of the same name. While Gounod's opera "Faust" has been performed thousands of times, his "Mireille" set in Provence is now rarely performed. The opera showcases aspects of Provençal culture described in Mistral's poem, such as the folk dance called the Farandole, and beliefs in witches and sylphs.
Cooke triplet lens with freeform surfacesDave Shafer
The document discusses optimizing a Cooke Triplet lens design for a strip field using freeform surfaces. It finds that with 10th order conventional aspherics on all surfaces, the design can be diffraction-limited over a 20 degree field at f/2.5. Replacing the aspherics with 10th order freeform surfaces and optimizing for a 20x1.5 degree strip field improves performance tenfold to a wavefront of 0.0040 waves rms. Narrowing the strip field to 20x0.5 degrees further improves performance to 0.0025 waves rms, showing the benefits of freeform surfaces for strip field designs.
Modified freeform offner, august 11, 2021Dave Shafer
An Offner 1.0X relay system can be given a greatly increased field size with good aberration correction by adding to the design two 45 degree flat fold mirrors that are given some freeform aspheric deformation.
A freeform aspheric version of the classic Dyson design gives much improved aberration correction and makes for designs that are fast speed and have a large field size, especially large rectangular strip fields
A wide angle fast speed unobscured freeform aspheric mirror design for the IR is shown to be enormous in size compared to an all refractive 3 element lens of germanium with conventional aspherics and better performance.
Schiefspiegler telescope with corrector lensesDave Shafer
This document contains contact information for David Shafer of David Shafer Optical Design and describes an unobscured 6 inch aperture f/10 telescope design from 1990. The design uses BK7 lenses and spherical mirrors to produce a diffraction limited image over a 1 degree flat field with no tilt at f/10 and has a length approximately equal to the focal length. It also references a simplified version of the design from a slideshare presentation that has a shorter length of half the focal length using tilted lenses and spherical mirrors with an optional fold flat.
A survey of some interesting Gregorian telescope designs includes some with all spherical surfaces as well as some with a 20 meter spherical f/1.0 primary mirror and sub-aperture corrector mirrors.

A humorous guide to better photography
1. A Humorous Guide to Better Photography
Dave Shafer
Taking better pictures can be a
piece of cake with these tips
2. The tips we will cover are sort
of like a light touch-up at the
barber. We assume you
already have some basic skills
and we just want to do some
fine tuning.
3. Whether your camera is an old original 1$ Brownie box
camera or the latest mega-camera it is the least important part
of taking good pictures.
4. Most important of all is
your eye and the brain that it
is hooked up to. We want to
train the little man here to
make better choices when
taking pictures.
5. My goal in photography is to express myself while linking
together creativity and humor.
6. I am always looking for
the visual equivalent of
a good joke.
7. My specialty is flower
photography but the principles of
good photography – like having
diagonal lines in your composition
- are universal.
8. Tip #1
Use unusual perspectives to
make more interesting
pictures.
A direct view may be less interesting
than a slanted perspective
9. An unusual perspective
can enhance the interest
of a scene. A view from
above is often effective.
You can climb up a
church steeple and get a
good view. This is
Nordlingen, Germany
17. Sometimes it is hard
to find the best
perspective for a
photo or for its final
version. This amazing
“Swiss Church on the
Edge” photo from
Luzern shows a
church where you
don’t want to go out
the wrong door. I
shot it from a gondola
with a telephoto lens.
18. But here is another shot from
further away and now you can see
the incredible straight drop and
how long it really is. But with this
photo you can barely see the
church and with the first shot you
can’t see how long the drop is.
So there is no way to get an
optimum single photo.
19. People in foreground boat
can lead you into a picture.
– Czech Republic.
Tip #2 – use people to pull
you into a scene
26. Tip #3 – look for
diagonal lines
when composing
a picture.
Diagonals in
photos are
visually much
more interesting
than horizontal
and vertical lines
30. This photo of the Creature
from the Black Lagoon has
strong vertical and horizontal
lines and that makes for a
pretty static composition.
Here her crooked leg makes
all the difference and puts a
strong diagonal right in the
center. It is a much more
dynamic composition.
31. Here too the girl’s diagonal oriented torso
and legs make for a dynamic image.
And the crocodile’s body is not horizontal in
the photo, making a better composition.
32. Tip #4 – simplify and avoid
distracting backgrounds
33. Be selective in your
composition. Too much
detail can weigh down
a picture with too much
baggage. There is no
need to show the
whole bird, flower,
person, etc. Pick one
center of interest and
then feature that. Crop
a photo if you can do
that.
34. Keep it simple - piling up too
much detail does not make
for a good picture
This cat photo is simple but has
a distracting background
35. Optimize background – try several different positions from which you take
the photo. Avoid distracting backgrounds.
Pretty , but distracting background Much better
36. Part of a dogwood blossom is just as good as the whole
37. A poppy center has lots of detail. African violet center is also
interesting. Don’t need to show whole plant or flower.
41. Wasp is a little off-center to avoid too
much symmetry, simple background.
Squirrel has diagonal lines, simple
composition, good background, focus
is on face.
42. Extremely simple
nude photo – uses
a diagonal
composition,
background does
not distract, very
unusual
perspective, has
human interest,
etc.
43. Tip #5 -Look everywhere for the human element
Daffodil Marriage SpatThere are “faces” everywhere
51. “The Critic”
I saw this in
Nuremberg and it
has both humor
and surprise. The
parents were
inside the store.
Europeans are
much more casual
than we are about
leaving children
outside a store
while they go in.
52. In my “A Long Marriage” picture I
used Photoshop to switch the water
reflections, to show that each
partner here has incorporated
elements of the other. Photos can
try to tell a story. But here,
unfortunately, most people do not
notice the switched reflections.
61. This photo tells a little story but
it is a mystery what it is about.
A sporting event?
When my son became a father of
triplets I knew that he saw them as
an extension of himself, as I showed
by using Photoshop here.
62. This shows a
great mini-story.
She is reading
the Kama Sutra
and he looks very
apprehensive.
63. 6:00 A.M. early
morning mists on
lake at Lakeville,
Connecticut
Tip #7 – experiment
with early morning
photos, late at night,
unusual weather,
water reflections, etc.
70. It may be hard to achieve some of these tips but it is worth the effort.
(this image reminds me of someone I used to date)
71. 1) Try unusual perspectives
2) Use people to pull you into a scene
3) Try for diagonal lines when composing a shot
4) Simplify and avoid distracting backgrounds
5) Look everywhere for the human element, or
humanizing slant
6) Try to tell a mini-story with your photos
7) Try night pictures, unusual weather, water
reflections Good luck with these tips!
