Here are some more information for Linhof Lens:

It was over 50 years ago that the author made his first Monday with aerial photography. The occasion was right after the terrible floods 1955 in northwestern Connecticut. Since that time it has remained a steady source of income. So work is not hard and it produces a steady stream of income.

The author first went into this business over 50 years ago. It seemed that the accepted way of doing business then was to take the photographs first, and then try to sell them. It didn't take too long for the author to realize that this was a fast way of going broke. After about the first year the author switched his tactics and went actively seeking customers.

It absolutely amazes me how well this worked we managed to get a list of clients that reads like the Fortune 500. It seemed that the larger the company the more willing they were to spend money on aerial photographs of their property. This included the top 10 companies on the Fortune 500 list, as well as hundreds of lesser clients. The lesser clients actually paid for most of the work that was done by the author.

Most of the assignments that the author developed were made by telephone. This included any number of real interesting clients. One of the clients that developed called me on the phone cold early on eight March morning. The author answered the phone and the voice on the other end inquired if he was home. Obviously he was or he would not of answered the phone. Once the person on the other end became aware that he was speaking to me he introduced himself over the phone with this, "Good morning my name is Stephen Spielberg."

My answer to that was, "Yeah, well I'm the King of England."

He assured me that he was indeed Steven Spielberg, and he needed some aerial photographs for the movie the Amistad. This was a movie about a cargo of slaves that took over a slave ship named the Amistad. As interesting as these assignments were, this was the kind of assignments I got. Over 50 years later I'm still getting assignments called in to me although I am no longer actively soliciting assignments.

One of the things that most people never believe even when they hear it is how much money there actually is in the aerial photography. Now we don't do anything special in taking these photographs. We work with a single lens reflex 35mm camera. It is actually an Olympus IS-3. All of the photographs we take are obliques. We initially deliver to the customer 4 x 6 inch proofs. These are large enough for the customer to see what he is getting an order whatever additional prints he wants. Very rarely, do any of these prints exceed 11 x 14 inches in size. If the customer doesn't want larger prints may have to tell me at the very beginning so that I can take the photographs with a camera that makes larger negatives. This camera is a Linhof Aerotechnika that takes a 6 x 7 mm negative. With a negative of this size you are able to enlarge the print to a much larger size. The largest photos we have ever made are 4 x 5 feet.

To take these photos we use both airplanes and helicopters. The ideal airplane is a Cessna 172 Skyhawk. The front seat window conveniently opens up, and swings up under the wing allowing you a clear shot of the site. The alternative when we are using a helicopter we take the passenger door off and just shoot out the open door.

With an airplane you are a limited to how close you can fly into the ground under normal circumstances the minimum altitude is 1000 feet, or over open countryside 500 feet. In practice however, we don't like to use an airplane under 1000 feet. Any photographs that we have to take at lower altitudes are made using a helicopter.

With a helicopter you are legally able to come in at a lower altitude. This has many advantages when you are photographing small sites, but under most circumstances you are able to work with an airplane for a little over $100 an hour versus using a helicopter for about four times more.

In order to make this pay I tried a bunch the assignments together, so that I am taking more than one assignment per flight. I prefer having it leased for assignments or as many as eight per flight.

Aerial photography is a very interesting business, and you meet some of the most interesting people while doing business. One of the things that we don't recommend doing though is trying to be both photographer and the pilot. You can't do both jobs at once, and you should have a pilot along to fly a plane or helicopter while you are doing the photographs. This is from my own bitter experience many years ago where I did try it, and almost killed me.

Influencing the Art of Jewelry Photography

The visual impact of perspective & sharpness control

By Avi Roth

Jewelry, as a photographic object is comparatively small in terms of three-dimensional extension. The range of movements offered by the view camera present great control over quality and visual presentation. This article about using a view camera in the studio-managed environment, discusses ways of deliberately influencing and modifying perspective and sharpness to attain

visual splendor and image quality

Unlike SLR or medium format cameras (“rigid body” cameras), the view camera has capabilities for a full range of movements: rise and fall as well as tilt and shift of both front and rear standards. This is very important in digital jewelry photography since simply stopping down a modern digital lens all the way to f45 or f64 is a poor approach in obtaining sharpness and can have a damaging effect on image quality. Modern digital lenses perform optimally toward the middle of their aperture range: f/11 for short focal lengths, f/16 for moderate focal lengths, and f/22 for longer lenses. Sharpness has other implications on image quality as well: surface quality, data density, and separation of planes and edges.

In practical terms, when photographing a round pearl necklace or a pendant on a 180º object surface with a tilted camera plane of 30º- 45º, the view camera can quickly and easily be set to achieve sharpness throughout the entire object plane at the optimum aperture without stopping down, while retaining natural proportions. An SLR or medium format camera on the other hand, must always be stopped down to a maximum lens opening of f32 and beyond to achieve a greater depth of field, with all the associated disadvantages of image quality.

A limited amount of sharpness can be re-gained in post-production by image manipulation, but only with considerable losses in terms of image quality, and with unpleasing pixel distortions. For known reasons, diffraction has a large effect at high line frequencies, and to ensure that enough line pairs reach the digital sensor to achieve good sharpness, it is best to avoid very small apertures! This is why when desiring great image quality, it’s imperative to achieve sharpness by adjusted depth of field vs. stopping down the lens opening!

Another good example of the view camera advantage can be seen when photographing a square jewelry gift box. How do you photograph a square item from a dramatic angle without converging lines?

With a medium-format camera it‘s not possible to compensate for converging lines at a small aperture like f/11 in order to get the entire subject sharp. Since lenses made for digital photography perform best in this aperture range a view camera like the Sinar p3, Arca, Linhof or Cambo would easily realize overall sharpness without loss of image quality while retaining the desired viewing angle.

The above examples demonstrate how the capabilities of a precision view camera with a full range of movements can achieve great overall sharpness at small apertures. But at the same time, the view camera also allows to create purposeful un-sharpness for artistic and creative interpretations. Utilizing the view camera’s range of movements to manipulate perspective and sharpness will create spectacular special images of even ordinary jewelry objects - especially in close-up range.

In jewelry photography close-up sharpness over the entire subject, at the optimum aperture for best image quality, is inconceivable without camera movements. If you are searching for a system that will help you capture the ultimate digital image quality, I would highly recommend thinking about a view camera studio-solution. There are at least two other components beyond the camera platform you must consider: the digital back, and digital lenses. It’s not inexpensive – but the results will justify the investment.
