Paying attention and noticing that which is around us.
Noticing the light and how it falls within your frame.
How does light affect colour and mood?
Using the photographs with digital applications to edit and enhance.
Print the photograph and work with the paper version.
For example: In this photograph the lines jump out for me...I want to print it and tear each tree away from the next and re set on a different background...just to see what happens... and maybe then tear the fence out and realign that somewhere in the image...all the while playing and noticing.
Using your own images which have been photographed, or images found on line and arranging and rearranging them through an App such as PicCollage can not only produce some effective work but can also bring about some interesting noticing as you focus more deliberately on images and how they sit in proximity to others.
Notice your response and be curious about it in a quietly mindful way.
