The Basic Lens Filter
When I bought my new Canon 450D recently, I also picked up a couple of UV lens filters and a polarising filter. The idea was to protect my two Canon lenses with the UV filters by leaving them permanently on the lenses.
With my 35mm Olympus SLR back in the 1980’s I regularly used the polarising filter and the decision to purchase one was almost a reflex action based on my previous experience with the 35mm camera. When I began to think about my use of the polariser I wondered whether, in today’s world of digital photography, the polarising filter was as relevant as it was for 35mm photography.
I decided to ask an expert, Robert Lachman, a staff photographer for the Los Angeles Times for over 30 years. Robert has a fascinating and informative website, www.PhotographyAndTheMac.com, and he was good enough to provide me with advice on the matter of lens filter usage. Robert’s reply to my question can be found here on his website. Robert is also a regular contributor to the Mac ReviewCast podcast with his photography based reviews.
