RPS All About Imaging Day

A symposium organised by the School of Media, Arts and Design of the University of Westminster and the Imaging Science group of the RPS.

I attened this event in Harrow today, very interesting exploring some of the more technical aspects of digital imaging.

Highlights for me were.

1. Reproduction of texture in artworks. Carinna Parraman from the University of Bristol discussed obtained texture in printed images like brush strokes of a Van Gough painting, a halfway house between 2D and 3D printing.

2. Using photographs (and maths) to visualise the damage on a ceiling at Hampton Court. Lindsay MacDonald. Using a Nikon D200 (hardly state of the art) to photograph the ceiling in very small precise areas, with flash in different angles producing multiple images, including HDR to further analyse to highlight cracks, flaking paint and previous restoration efforts.

3. Video evidence for legal use from CCTV images by Ken MacLennon Brown
This covered the difficulties of getting high quality images from CCTV cameras, good enough to stand up as evidence in court, given the wildly differing lighting quality, bandwidth requirements at different times of day – affecting compression eg. packed station concourse vs empty and quality of installed cameras and locations.

It was an excellent day, I am looking forward to the next one!

  1. This design is spectacular! You obviously know how to keep a
    reader entertained. Between your wit and your videos, I was almost moved to start my own blog (well,
    almost…HaHa!) Great job. I really enjoyed what you had to say, and more than that, how you presented it.
    Too cool!
