I presented at a London Photographic Meetup Group (LPMG) event this morning.
If you attended this event and would like more information on any of the topics that I covered please feel free to drop me an e-mail.
The presentation is be available to download from the LPMG Meetup site (here)
I mentioned a number of companies/suppliers... some details of which are shown below:
NIK Software - Post Processing Plugins for Lightroom, Aperture and Photoshop. These plugins are powerful and intuitive and make post-processing images quick and painless.
Fixation - Based in Vauxhall, Fixation run a business selling, servicing and hiring camera equipment. They also offer a competitive sensor cleaning service which can often be completed while you wait. Highly recommended.
