You can find interesting images anywhere. I liked the look of the fairly new car park floor and the marks left by the first few users. I went to town on these in Lightroom 6, learning a bag of new tricks along the way.
I have committed to the WAPF 52 x 2 project; producing one colour and one mono image per week for a whole year, with a book of the images to show for it. Not an easy ask. Six weeks in, the key has simply been to get out of the house. Apart from week 1, which was super-busy at work, it hasn't been too difficult. Being on holiday for the past 3 weeks has helped :)
I shoot for fun, with a Sony A7II, a Mavic Pro and my trusty iPhone 6s.
