Industrial and scientific photography and imaging

Imaging and image interpretation are absolutely essential elements of materials and metallurgical practice, and indeed, much of science in general. Having developed expertise generating photomicrographs through a variety of microscopes, REXP2 Research LLC takes industrial and scientific imaging one step further and offers industrial photography and video services. In graduate school, it was about boxes of Polaroid type 55 film. This inspired learning film and print development and research into historic photographic processes. While wet chemical film and print processing are near and dear, today we embrace digital capabilities, as they offer superior resolution and a greener process stream in most situations. However, the lessons of shooting film, processing film, and printing negatives are not lost on our current work. In technical and scientific photography, one carefully composed and exposed photo at the critical moment is worth infinitely more than a burst of digital shots one second too late.

We are experienced photographing plant facilities, products and manufacturing processes in action, high temperature behavior, as well as micro scale details. We use digital cameras individually optimized for resolution or low light performance. In rare circumstances, film based view cameras can offer perspective and depth of field control required for a particular application and in these instances we have portable capabilities to use 4×5 and 8×10 in. film formats. In house capabilities include time-lapse full scale, macro and micro capabilities, as well as high speed video to 120 fps. Our lens complement, made up of mostly Nikon and Leica lenses, covers the range from fisheye, and 15 to 1000 mm focal lengths relative to a 35 mm frame size. We take full advantage of the Scheimpflug effect, a mainstay of view camera work, by using tilt-shift lenses to control depth of field and perspective. Through understand the behaior of light and how various filters, such as polarizers, IR, mirror, and didimium, we can solve complicated industrial and scientific imaging problems. By careful control of lighting and multiple exposures, we can emphasize both stationary features and their motion while in operation in one image. With control of depth of field, we can eliminate distracting and extraneous detail in backgrounds. We perform image processing and analysis for both technical measurement and visual appeal. Our image analysis work primarily relies on ImageJ, Adobe Photoshop and custom Python code.

Finally, we can help you interface photographic and imaging equipment with your plant facilities. For example, many fine microscopes were not designed for potomicrography. However, using simple and low cost methods, these instruments can become imaging powerhouses for your business. We have consulted with various universities on how to adapt low cost commercially available photographic equipment to instruments such as tribometers and contact angle goniometers. 

Due to confidentiality and release issues, it is not possible to present most plant and product photographs here.  However, the photographs and videos show at right are a small fraction of our work.
