JTC 12 (D1/D2/D8): The measurement of Sparkle and Graininess
Div2 of CIE has validated the creation of aJoint technical committee (JTC) on sparkle, chaired by Alejandro Ferrero (CSIC, ES), and co-chaired by Youngshin Kwak (Head of CIE Div1, KR).
The term of reference of the JTC is “To provide a methodology to measure sparkle and graininess, and to develop a measurement scale. Measurands will be defined and the requirements for their measurements will be well normalized, in such a way that different instruments can provide the same spectrophotometric data from the same specimen. A psychophysical method will be recommended to obtain visual data, and its correlation with the spectrophotometric data will be worked out to develop the measurement scale for sparkle and graininess.”
If you want to joint JTC Sparkle, you are welcome.
Chair: Alejandro Ferrero (ES)
Recommendation on the geometrical parameters for the measurement of the bidirectional reflectance distribution function (BRDF)
Next meeting of TC2-85
Next meeting will be held in Eindohoven (NL) around June 12, 2018 during the Div2 annual meeting. A special emphasis will be given to polarization effect in BRDF measurements during this meeting. If you want to joint TC2-85, you are welcome. We need your support and knowledge are user of BRDF measurements, as multi-angle spectrophotometer or goniospectrophotometer manufacturer, as standard artefacts manufacturers.
We have an new industrials who jointed the group of BiRD’s stakeholders.

Elcometer Ltd. has been for more than sixty five years a world leader in the design, manufacture and supply of inspection equipment to the coatings, concrete and metal detection industry.
25-27 April 2018, Alicante, Spain
The meeting will be focused on the exchange between BiRD consortium and BiRD stakeholders, as we did in the past during xDReflect. In the agenda, talks about our research on BRDF measurement at NMI level and breakout sessions where we can have your feedback and discuss needs, issues and collaborations.
Venue: Culture UA center
Address: Calle San Fernando 40, 03001 Alicante – see on googlemaps
We are currently building the stakeholder committee of BiRD project! It is opened to all person/institution/company/committee interested in the topics of BRDF, gloss, sparkle and datafile format. Terms of Reference of the Stakeholder Committee describe the purpose and role of the Stakeholder Committee and can be found here on the website. If you want to joint the committee, please contact us. Stakeholder committee will be formed first half of January 2018.
We have 3 new industrials who jointed the group of BiRD’s stakeholders over the last weeks. We would like to welcome and introduce them to you.

Bibliography about gloss, sparkle and BRDF measurement
References to literature about BRDF measurement on different surface effects, e.g. gloss, sparkle, white standards have been added to the References page.
You can either use the list with bibliografy or use the reference database about measurement of appearance attributes.
Please find below a link to an online survey intended for industries making surface reflectance or colour measurements. If this is relevant for you, we appreciate your filling out the survey, which shouldn’t take more than a few minutes. The information we gather will be used to help CIE decide next steps with regard to standards, guidance and training.
The survey will remain open until 31 July 2017.
Many thanks for your time.
The next meeting will be at Jeju Island (Korea), between 26-28 October 2017. We will have this meeting after CIE TC2-85 meeting. Please, visit the website of CIE midterm to get more information about the whole event and to register (http://cie2017.org/). If you plan to attend only CIE TC2-85 meeting and BiRD meeting, you should register only for “Division/TC Meetings Delegate” (see http://cie2017.org/registration.php)
