Everyone has some bad habits. This is one you'll definitely want to avoid as a photographer.
Coming to you from James Popsys, this great video explores the idea of how we assign blame for our failures in photography. Not accepting responsibility for our failings as photographers can have a lot of negative and sometimes very expensive consequences. One of the most common (and costly) manifestations of this is blaming gear when we miss a shot. That's not to say that sometimes, yes, your technique was sound and your autofocus system simply couldn't keep up with the fast action or something like that, but a lot of the time, people fall into the trap of thinking they're missing shots or not producing quality images because their gear is holding them back, and they end up dropping large amounts of money on higher quality equipment only to find they're producing the same photos as before. Not only is this obviously quite detrimental to your wallet, it also holds you back from improving until you're really honest with yourself and you address the true root of the problem. Check out the video above for Popsys' thoughts on the matter.
