Many of you interested in contributing to this symposium might be wondering, and have concern, about the current situation in Hong Kong and how this might impact upon not only the symposium but importantly the travel arrangements and security of attendees at the symposium.

We can advise that the situation is being closely monitored, and contingencies are being arranged to ensure that the symposium will take place in April next year.

Meanwhile the abstract submission system for the symposium is open, the deadline for submission is October 23, 2019 - we look forward to receiving your contribution.

TC 4-58 is preparing a guideline on obtrusive light from colourful and dynamic lighting. For this purpose, the TC is collecting information on existing national and regional regulation, standards and guidance documents for obtrusive lighting (i.e. light emission and ingression). We therefore would be grateful if you could provide some information on obtrusive lighting in your country, with emphasize on coloured and dynamic aspects. Please send all relevant material to the chair of the TC Steve Lau at Stevelau@china-yd.com on or before 2019-03-15.

The CIE Joint Technical Committee JTC 12 (D1/D2/D8) “The measurement of sparkle and graininess” is discussing the definition of the measurement scales of sparkle and graininess. For this purpose, it is collecting visual data, which can be used for scaling or for devising texture difference formulae. Please, if you have obtained or you are planning to obtain visual data of sparkle and graininess and are willing to share them, or if you want to collaborate in the development of the measurement scales of sparkle and graininess, contact to the JTC 12 Chair, Alejandro Ferrero
