自20世纪60年代以来，公众对景观的评估经常使用摄影表现。与现场观察相比，这些评估的可靠性和有效性如何？在本研究中，参与者被要求根据一个有限的功能：该地区的生物多样性来判断不同的地区。在互联网上提供了六个不同研究领域的数字化照片，沿着一份由语义形式组成的调查问卷，其中包含与照片相关的特定词语/表达（每个领域四个）。参与者是通过邮件列表和非正式联系人招募的。这些结果与一项研究进行了比较，在这项研究中，学生和生态学家使用相同的表格对相同的地方进行了评分，但这次是现场评分。互联网参与者还被要求说明他们的职业/教育，以便进行比较。比较显示现场和照片之间的评级的差异，但主要的区别是由现场生物学家表示，关于最高的经验丰富的生物多样性价值的地区，可能是由于他们的专业知识和使用更多的感官比可以使用时，判断照片。特别是关于外行人，它的结论是，现场和基于照片的评级之间的比较是不足以让我们确定是否是适当的使用一种方法作为替代品。
Since the 1960’s, public assessments of landscapes have often been carried out using photographic representations. How reliable and valid are these assessments compared with on-site observations? In the present study, participants have been asked to judge different areas in terms of a limited feature: the biodiversity of the area. Digitalized photos from six different study areas were made available on the Internet, along with a questionnaire consisting of a semantic form with specific words/expressions to be rated in relation to the photos (four per area). Participants were recruited via mailing lists and informal contacts. These results were compared with a study in which students and ecologists had rated the same places using the same form, but this time on-site. The Internet participants were also asked to state their profession/education to make comparisons possible. The comparisons revealed differences between on-site and photo-based ratings, but the main difference was expressed by on-site biologists regarding areas with the highest experienced biodiversity values, possibly due to their higher degree of expertise and use of more senses than can be used when judging photographs. Concerning laymen in particular, it is concluded that the comparison between on-site and photo-based ratings is not conclusive enough to allow us to determine whether it is appropriate to use one method as a substitute for the other.
