An intersting example of 'the experiment' - slightly confused by having three images rather than two and I am not entirely sure I really know which is the 'fluffy' image and which is the 'lets get down to business and do serious but unapEPZealing' shots, is?
The 'tin lid' V2 promises so much more than the very mildly challenging V3 (and probably only mildly challenging because of the mono treatment - would you have posted a colour version? and if you had posted a mono version of V2 might that have then taken on the mantle of unapEPZealing?).
So I am trying to judge this not on colour or lack of it and I still think V2 has much more on offer. Leave it three months and post the reverse, V2 in mono and V3 in colour and see how the result compares?
BTW I wish I had a thimbulfull of your talent - all are quite excellent.
