I am excited to announce I have accepted an invitation from Formatt-Hitech to become one of their UK brand ambassadors. I plan to test more of their filter and possibly develop some of my own variations with them in the near future.
I am still a massive believer in filtration being used in front of the lens and do this often in my own work about 90% of the time.
