Colloquium by Warren A. Keller

The Art of Astrophotography


Mr. Warren A. Keller is a well known American astro-imager and teacher, whose photographs have appeared on NASA's Astronomy Picture of the Day (APOD) website.  He will explain why astro-images are an important art form, rather than a scientifically accurate record of heavenly objects.  Attendees will also hear the secrets to creating an award-winning astro-image, beginning with composition and acquisition, and proceeding through both pre and post-processing.  He will also share with the audience, his passion for teaching astro-image processing in the digital age.

沃倫·基勒先生 (Mr. Warren A. Keller) 是一位知名的美藉天文攝影家及老師,他拍攝的照片曾多次在著名的美國國家航天局的每日一天文圖片(APOD)出現。他將解釋為何天文圖像是一種重要的藝術類別,而非視作天體科學的準確記錄。與會者還將聽到如何打造屢獲殊榮的天文圖像之秘缺,由如何取影和攝錄,並怎様進行前期之凖備功夫和後期之圖像處理工程。他也會與觀眾分享他對在數碼時代,透過互聯網推動天文圖像處理的教學熱情之何去何從。
