actually I think it's not quite long enough. 24x36 (and 6x9) is the closest of the common formats to a golden rectangle - I think this is one of the reasons why it is such a popular format. If he'd made it 24x39 we'd have been right there, as near as dammit. 24x38.83281573 is a perfect golden rectangle. The golden ratio is 1:1.618. --- Bob mailto:[EMAIL PROTECTED] - This message is from the Pentax-Discuss Mail List. To unsubscribe, go to http://www.pdml.net and follow the directions.
