Please look at this website "The Mindful Eye" by Craig Tanner, if ever I feel a little lost and lacking inspiration I will pay a visit to his brilliant collection of 'Daily Critique' and 'Light Diary' videos.

This link is to a Light Diary Vidcast in which the theme is “Discount Store Parking Lot”. Craig discusses 'a very basic “workflow” for composition of any subject', 'the idea of leaving room in your process for serendipity', 'conceptual compositing', 'including the possibility of combining multiple images in the creative ideas with which you are willing to work' and also discusses 'the power of lowering the threshold that needs to be met for the creative process to be engaged'.
A really interesting video which I am sure will be of interest. Please dip into the hundreds of other videos on this fascinating website
Thanks again!
