From its invention, photography has been used to visualise events and objects that are invisible to the human eye, either those that are too slow or too fast to perceive, or subjects that appear differently in ultraviolet (UV) or infrared (IR) light.

This unique workshop will examine the techniques for visualising the invisible world: UV reflected and fluorescence photography can reveal hidden patterns in flowers which only insect eyes can see, and IR photography can be used for pictorial effect as well as identifying plant disease for example, whilst, time-lapse and high speed photography can be used to show plant growth, or high speed spore dispersal.

UV reflected and IR photography require the use of specially modified cameras and specialist filters, and the requirements for this will be discussed and demonstrated fully during the workshop. If participants wish to get a camera modified before the course they are welcome to contact the tutor before the start of the course.

Adrian’s web site: is devoted to the subject, and includes images and various ‘starter guides’. His new book: Digital Ultraviolet and Infrared Photography (Focal Press) was published in 2018.

Whilst much of the work will be carried out indoors, there will be some photography in the field at nearby locations for IR and time lapse photography.
