The Golden Mean

I was prompted to look again at the Golden Mean after a comment on Tree in Mist at Brotherswater on The Shark Tank.  One of the commentators suggested that the tree might be better a little to the right.  I have always since Art College tried to use the Golden Mean, but I decided to check how far off I was in this particular photo.

I printed off the photo then using a ruler produced the above Fibonacci spiral.  I have discovered that 'my' golden mean is not the same as Fibonacci's!  It looks as though mine has drifted a little towards the centre.  Is this a problem?  I don't think so.  If my photos look right, then they are right - at least for me.

Maybe the tree should have been a bit to the right?  Dunno.
