Cambo Digital Repro #3 – WRS400 REPRO Camera

Cambo Digital Repro #3 – WRS400 REPRO Camera

There are several cameras available from Cambo that can be used for digital capture. The camera shown is the WRC-400 REPRO an extremely lightweight and compact platform.

The WRC-400 is a technical camera that is precision machined from high grade aircraft aluminium, to match the demands of accurate capture. You can use the camera on a copy stand or Studiostand to reproduce cultural heritage, artwork and artefacts.

Why use a technical camera?

There are several reasons why a technical camera should be used, of course this is dependent on the quality of image you require and the output reproduction.

High quality resolving lenses from Rodenstock and Schneider should be used, these are classed as digital lenses. A wide range of digital backs can be attached from Phase One, Leaf, Hasselblad and Sinar, several different camera mounts are available.

A technical camera is more flexible when used for reproduction work and has the added advantage of applying camera movement (shift) that isn’t available when using a medium format camera system.

Capture using a technical camera

First you will need to assemble the camera and positioned it using the built-in levels so that the capture will be squared. There are horizontal and vertical levels built-in to the WRC-400.

What is Camera Movement?

If you look carefully at the WRC-400 image you will see a chrome wheel to the left and a scale with increments 20mm to the left and 20mm to the right. At the zero position the sensor will be positioned exactly in the middle of the capture area. This camera movement is called shift, as we can shift the sensor to the right and to the left and then stitch the images together.

Sensor sizes

If you choose to use a large medium format sensor then there will be less shift as you can only move the sensor within the image circle. This is restricted when using a medium format camera as there is no rear shift and you can not stitch two images together as you can with a technical camera.

For the purpose of this blog let’s say we have a sensor that is 44x33mm as a larger sensor is out of our price range. We can still capture more pixel information by shifting the sensor to the right, to the left and then stitch the images together.

The image below shows a 44x33mm sensor capture area, the rings around the sensor is the image circle of the lens. The Blue image circle is from a Rodenstock 60mm lens, whereas the Purple image circle is from a Schneider 90mm lens. The image circle varies depending on the lens structure and focal length.

Sensor1

As already indicated the WRC-400 has 20mm shift left and 20mm right, totalling 40mm. As you can see below we have shifted the mid-point of the sensor 16.5mm to the left and 16.5mm to the right, doubling the total capture area.

Sensor2

  • The sensor capture area is 44x33mm, by shifting it is now approx 44x66mm.
  • Pixel resolution is doubled from 50Million pixels to 100million pixels.
  • The print output at 300dpi is increased from 70.1×52.6cm to 70.1×105.2cm

Note: The capture and output sizes will vary slightly as there will need to be a small amount of overlap for stitching. Also the aperture used will make some variation. However, the image will be almost double in size with 2 captures.

More information about sensor size, lenses and shift can be obtained from your local Cambo dealer or you can email your questions directly to Cambo.

Sculpting with Light by Harold Ross

Sculpting with Light by Harold Ross

Harold is a professional photographer based in Pennsylvania. He graduated with a degree in Fine Art Photography from MICA, in Baltimore, in 1978, and after graduation, producing fine art, taught photography at college level for several years. He opened his commercial studio in 1987, and for almost 30 years, light painting has been the only method of lighting that he has employed. (He refers to his process as “Sculpting with Light”). 

During that time, Harold has been creating distinctive work in the studio and at locations (such as museums), as well as in the night landscape. He also teaches workshops in light painting and regularly gives lectures on his work and process.

The Cambo Wide RS is my go-to camera for night landscapes and location work. The small size, quick levelling and set-up, shift movements, as well as the terrific quality of the wide angle lenses are a big plus. Absolute stability is required, and the Cambo fits the bill.

All of my photographs are made with light painting, and with a process and workflow that I developed called “Sculpting with Light”. I make multiple long exposures using Capture One (tethered) while painting the light onto the subject(s). This special method of lighting reveals information about the subject that isn’t clearly seen under normal lighting conditions. In other words, the depth, dimension and texture of these subjects is enhanced by my particular lighting techniques. These separate captures are then blended together using special masking techniques in Photoshop to create the final image.

I shoot a variety of subjects within my areas of interest, and my work is currently organized into several portfolios; Night (Landscapes shot at night), Still (still life work), Forged (images of things that were made by hand, in dedication to the people that used their hands to create the tools and machines of our past), Shopcraft (Similar to Forged, but concentrating on the places where people worked), Biltmore House (a standalone project of images made at The Biltmore House, America’s largest private residence), and Oil Cans (images of vintage oil cans).

In addition to Capture One and Photoshop, I also use X-Rite’s i1 Pro 2 and iPublish software for colour management.

Charles; Your photography is exceptional, are you shooting commercially or is your work personal projects?

Harold; I was a commercial photographer for my entire career, but I’m now concentrating on fine art photography and teaching workshops, so now, all of my work is “personal”. All of the Night images are shot with the Cambo system, as well as all of the location images in the Forged and Shopcraft portfolios, as well as the Biltmore House images.

Charles; Which Cambo camera system and lenses do you use?

Harold; I use a Cambo Wide RS, and a Cambo Wide, and a Cambo Wide Compact. All are used with Phase One digital backs. For lenses, I use a Schneider 24 Digitar XL, Schneider 35 Digitar XL, Schneider Digitar 47 XL and Rodenstock Apo 70 lenses. I am very interested in using the Actus-DB for studio work in the future, and I’ve already had students bring them to my workshops. The camera is very impressive and it’s definitely on my wish list!

Charles; Did you have a specific reason for buying Cambo cameras?

Harold; Several reasons actually; familiarity with the brand (I first used a Cambo view camera back in the 70’s), movements, and lens selection were the most important reasons. My first digital body was the Cambo Wide, so there was a natural progression to stay within the brand.
