I am not a fan of the Photographic Workshop for learning Photography.
My students on a course of study return each week after exploring a topic in depth, ISO, for example, they are supported by my virtual learning site on my website, where they can visit the learning again we learned in class and follow helpful links that relate to that topic. The students are set small homework to upload so I can give feedback and more importantly they get to COME BACK week on week, so if there is anything they didn't understand, we can re-visit that learning. My students don’t feel stuck or stranded, or that they have paid a lot of money for a one day workshop yet are still feeling frustrated and unsupported.
When you embark on a course of learning, it's important that the teacher is not only very skilled and knowledgeable about their subject but has the skills and the empathy to teach. Professional teachers are trained to know how the brain receives, recalls and retains information. They spend many years learning how to craft and plan Schemes of Work so the learning is scaffolded and builds into a complete comprehensive body of work with clear assessment criteria, so student’s learning is checked and confirmed!
So many people I teach have been on other more expensive one-day workshops or courses and are still confused by some of the information they have received.
Make sure you learn with a trained qualified teacher and someone who has learned their craft in industry.
