CONTENT 2.11 Connecting the Cables 1. Connect the digital back with the flash socket [33] on the shutter, using the Trigger cable [42] that is supplied for this purpose, one end of which is plugged into the Trigger socket [45] on the digital back and the other end is plugged into the Flash synchronization socket [33] on the shutter. 2. Thread the Cable release [41] into the Shutter release lever [36] on the shutter. 41 42 Fig.
CONTENT 2.12.2 Photographs on roll film 1. First load a film into the roll film magazine and wind it to the first frame (to this end, please follow the instructions that come with the Hasselblad roll film magazine). The roll film magazine can be coupled to, and uncoupled from the Sinar arTec HB-V camera exactly like a digital back with a Hasselblad-V interface (please also see chapter 2.4). 2. With the Sinar arTec camera in the Viewing position, you can now compose your picture on the focusing screen. 3.
CONTENT 3 Image Settings and Exposure 3.1 Possibilities of Image Settings The Sinar arTec permits all kinds of adjustments, just as we are familiar with them from view camera systems: Horizontal and vertical shifts as well as tilts and swings. The Sinar arTec camera’s operating elements used most often for tilts are user-friendly and they are positioned at the back of the camera (see figure 23). 5 25 5 15 23 25 15 23 3.
CONTENT The vertical shift is the most frequently used perspective correction in architectural photography. This shift is used whenever converging lines in photographs of buildings are to be straightened. Converging lines occur when, for example, a tall building is to be photographed from ground level, so that the camera has to be tilted upwards to cover the full height of the building.
CONTENT Fig. 26a: When a building is photographed without using the camera movements showing both the front surface and the side of the building, the front facade perspective is bound to converge drastically. Fig. 26b: When the front of a building is to be shown without converging lines and without using camera movements, the side view of the building disappears. In this case the camera viewpoint is exactly perpendicular to the facade. Fig.
CONTENT 3.2.4 Horizontal Perspective correction with the Sinar arTec To perform a horizontal shift on the Sinar arTec, first loosen the Locking lever [6], then use the Micro drive [5] to make the horizontal shift to the desired extent and lock it in that position by tightening the Locking lever [6] again. A scale [4] above of the horizontal Slider [1] is calibrated in mm to serve as a reference in case that setting is to be repeated later on (see also chapter 3.4.2). 3.3 Swings and Tilts 3.3.
CONTENT 3.4 Step by Step Towards the Exposure 3.4.1 Image settings 1. With the Sinar arTec being in Viewing position (see figure 30a) set the lens to viewing mode by opening the shutter [34] and opening the aperture to maximum [38] (also see chapter 2.9). 2. Set all the desired movements (camera position, perspective, vertical and/or horizontal displacements, swing/tilts, and focus) 3.
CONTENT 4 Accessories for the Sinar arTec Camera 4.1 Lenses The Sinaron Digital CEF Series of Lenses are made for use on the Sinar arTec camera. Sinaron Digital lenses were designed specifically to meet the high demands of digital photography. All Sinaron Digital Lenses have the resolving power of at least 50 pairs of lines/mm all the way to the edge of the image circle.
CONTENT 4.3 White Shading Diffusor Fig. 33a: White Shading Diffusor Fig. 33b: Sinar arTec with attached Shading Diffusor The White Shading Diffusor 551.43.097 is mounted on the lens by means of a Lens Adapter Ring for use in making a shading exposure. The latter serves mainly for the computed compensation of the systemic vignetting towards the edges of the image.
CONTENT 4.5 Lens Shade 4.5.1 Why should you use a lens shade? With an unprotected lens, stray light from outside the subject area can reduce the contrast noticeably. That is why a lens shade is an indispensable tool in professional photography. But a lens shade can only provide the best protection against stray light when it is optimally tailored to the angle of view, and the Sinar System offers several solutions for that purpose.
CONTENT 4.6 Swiveling Polarizing Filter Fig. 38: Swiveling Polarizing Filter Fig. 39: Sinar arTec with optional Polarizing filter Polarizing filters can be especially useful for eliminating distracting reflections in outdoor photography. The Sinar Swiveling Circular Polarizing Filter can be mounted on the Sinar arTec camera by means of the optional Filter Rod Holder and a Filter Rod (also see chapter 4.4).
CONTENT 5 Compensation of the Light Fall-off of a Lens With Shading 5.1 General Shading files are used in professional digital photography work. A Shading file is a white reference image that describes the light fall-off of a particular setting. This unwanted fall-off can be corrected by means of appropriate computations. When photographs are created directly on a computer by using the Sinar eXposure™ Software, a Shading calibration is made at the beginning of a scene (in the "Exposure" menu).
CONTENT 5.3 Using a Shading Image in the Sinar eXposure™ Software 5.3.1 Preparation You have already installed the Sinar eXposure™ Software Version 6.1.1 or higher on your computer and you are already familiar with its current functions. The section that follows supplements the integrated help function of the Sinar eXposure™ software.
CONTENT Fig. 46: Contact sheet in the Sinar eXposure™ software: Marked Shading images The gray background that now surrounds the images designates the Shading file and the images to which it ha been allocated. The pie chart diagram on the right side indicates how strongly the Shading correction should be applied. With every click on that diagram, the correction is increased by a quarter. 5.3.
