On what will probably be my next to last poppy shot I decided to position the camera so that a poppy head was filtered by a foreground poppy petal.
The long lens (500mm Tamron) has thrown the front petal totally out of focus resulting in a colour cast over the entire photo but no detail. So the background focused poppy head is sharp with a colour wash over the top.
Cokin used to sell a filter that had a colour effect similar to this so I'm pleased with the natural (free) result.
