Photographs copyright: DAVID McMAHONI've been waiting weeks for the right time to capture this sequence. What I wanted to do was take a photograph at the same time, every day, of the same rose as it unfurled. I experimented with different colours, different varieties and different angles. The first shot in this sequence (above) was taken on Friday afternoon.

This is the second shot (above) in the sequence, taken on Saturday afternoon. Have a look at the centre of the rose. It is pure symmetrical perfection, as each individual petal forms an elegant pattern in synch with all the others. You'll see that the real change from the day before is in the mid-section of the bloom, with a little movement in the centre as well.

But the third shot, taken on Sunday afternoon, shows the clear result of the hotter weather. The rapid progression is quite dramatic. The rose has suddenly reacted to the sunlight and the heat, revealing itself in all its buttery splendour. For the record, it was a climbing Freesia and yes, they are as fragrant as they are beautiful. I hope you like this pictorial experiment. Do let me know ....
