CHSOS just added STACKSHOT to its instruments in order to document small artistic and historical objects. STACKSHOT is an automated macro rail for focus stacking and it’s coupled with Helicon Remote and Helicon Focus to shoot and elaborate the stacked images.
Focus stacking macro photography
Photographing small objects that are flat is pretty simple and straightforward. On the other hand small objects that extend in space, as a piece of jewelry, are challenging because macro (close-up) photography implies very shallow depth of field. Even at large f-number it is possible to focus only a plane of the subject and the rest is out of focus. To get all the subject on focus it is necessary to use the focus stacking method. The camera shoots photos while it is moved from far to close to the subject. Each picture will have a portion of the subject on focus. Specialized software, such as Helicon Focus, takes care of elaborate all the stacked images and produce a resulting picture that is all on focus. STACKSHOT is an automated macro rail that makes all this workflow automatic. I need, eventually, to mention the amazing customer care service that the company provides. Immediate reply to my emails and also got the system repaired and shipped back in no time and no shipping cost.
We do run a lot of initiatives, Stay on top of things!
Macro Photography lenses and methods.
A suggested publication regarding macro photography techniques:

Pigments Checker is for photographers, conservators and scientists interested in technical documentation of paintingss. It has 54 swatches of historical pigments designed for infrared photography, ultraviolet photography and other technical photographic methods for art examination. Check it out!
Pigments Checker is a collection of 54 swatches of historical pigments that have been applied using gum arabic as a binder on a cellulose and cotton watercolor paper, acids and lignin free. This paper is not treated with optical brighteners, it’s slightly UV fluorescent, and it reflects IR. Two cross-hair lines, 0,2 mm (vertical) and 0.4 mm (horizontal) are printed on each swatch of paper before the application of paint, in order to have a means to evaluate the pigments’ transparency in the IR and IRR imaging. Among all the pigments and their varieties ever used in art these pigments collection select the most used ones from antiquity to early 1950’.
