Technical Photography Filters set (v.2) – Robertina
We redesigned our Technical Photography Filters Set to be more simple and fast. It’s called Robertina.
CHSOS TP Filter set v.2 Robertina 760 euro + 30 euro (shipping)
NEW Technical Photography Filters Set (v.2) Robertina is composed of 3 scientific filters (52 mm thread). They are all the filters you need to perform Technical Photography (TP). In our Training programs, we illustrate how to use these filters to produce technical photos such as IR (Infrared), UVF (UV Fluorescence), UVR (UV Reflected), IRFC (Infrared False Color) and IRF (IR Fluorescence). These images reveal information such as underdrawing, pentimenti, and retouches. They can enhance the reading of faded documents and provide a tentative identification of pigments.
One spectral band at a time! The new Filters Set Robertina v.2 features custom-made special filters. We had them manufactured by our collaborator Optical Components developer to match our needs in Cultural Heritage technical examination. The filter set is composed of 3 filters, simply named UV, VIS, and IR. The UV filter allows ONLY UV radiation. We use it for UVR photography. The VIS filter allows only VIS radiation and it is used for those photographic methods that look only into the visible part of the spectrum, such as VIS and UVF. The IR filter allows ONLY the infrared radiation and in particular that furthest part of it that the camera can still detect, over 900 nm. This is where the pigments become more transparent and we get the most out of our IR photo. The filter is then used for all the photographic method using IR radiation, such as IRF and IRT. In the previous version of the Filters set, we needed to apply two filters together to achieve this precise spectral selection of only UV, VIS or IR. Thanks to this new custom-made set with only 3 filters we can get the images faster and sharper.
It works with any full spectrum camera. The Technical Photography Filters Set Robertina can be used with ANY full spectrum digital camera. No matter if you already own a Nikon, a Canon or whatsoever full spectrum camera, our filters set will provide optimal results.
For 52 mm lenses. The current filter set works on lenses with the 52 mm filter thread. These are the most common lenses. Later this year, we will propose a pro version of the filter set to fit large lenses. This 52 mm version is fine for the largest part of users which will have standard lenses, such as the Nikon Nikkor 50mm AF 1.8 D 50 mm lens we use for Technical Photography during our Training program and in our art examination workflow.
Filters quick release adapters. The 3 filters are mounted on magnetic supports. Performing Technical Photography means changing filters countless time. Using standard filters with their frame to screw on the lens will lead eventually to a wore off thread on the lens or on the filter frame. To prolong the life of your lenses and filters we created a magnetic adapter. You just need to slide the filters on the support that is attached to your lens. For Technical Photography it is important the camera is kept steady for final registration of the images. So, it is very important to have magnetic adapters for the filters to minimize the displacement of the camera. The filters set comes with our quick release adapters which make easy, safe and effortless to change filters on your lenses. These magnetic snap-on adapters free you from the tedium of changing filters and the wearing out of the threads on the filters and on the lenses. They do not harm the camera and the lenses, as well as the focus mechanisms, media cards, drives and other electronics.
