五月十日太阳耀斑爆发让多伦多地区有机会看到极光。拍摄前参考了一下网上的建议:
Focal length 14-50; Manual control focus and exposure; White Balance 3500-5000k (4000); Aperture f/2.8-f/4; ISO 400-3200 (1200); Speed 1-30 (8-10) depending on the brightness and movement。
当然各种参数要根据当时的情况而定。摄后分析照片发现尽量保持足够的曝光量才能更显极光的绚丽。 以下照片摄于多伦多附近的 Lake Simcoe。
