I would really appreciate it if product "reviews" written by people employed or sponsored by the product manufacturer were obviously labeled as such. It is a dishonest practice to label something a "review" without disclosing any relationship between the author and the product manufacturer. In many industries in the USA, this would be illegal. It believe it is illegal in this case too, but I am not a lawyer. Simply as an example, I will point to the latest review of the Marelux SOFT snoot in UWP magazine #131. The author who is sponsored by Marelux says she was "lucky to get my hands on one" and "Marelux products are incredibly well made" but nowhere is her relationship with Marelux disclosed. At least the similar article posted on wetpixel.com stated that she is a brand ambassador, even if it is kind of tucked away at the bottom.
Would anyone else like to see more honest product promotion in the content we depend on for education? I don't think it would have a harmful effect on product sales. My opinion of a brand would only increase if they were up front about the fact that they are supporting these excellent photographers.
