Last weekend I photographed a 10K -- it wasn't a paid shoot, just a shoot. But, as Vincent Versace says, the "hairball" got the best of me. Vincent describes the moment of a stressfull situation while shooting as the "Hairball".
You see I thought I was all dialed in -- it was easy -- the subject was fairly static, the my zoom was maxed -- iso at 200 -- aperature priority - done !!
Upon getting home -- the images were not that sharp - how ?? It was obvious - dialed in to 200mm I was only shooting at 1/135 second... I was so disappointed - and now I know to keep this in the mental toolkit. As with film - your shutter needs to at least match your focal length -- if you are shooting a cropped sensor then double it to be safe.
I knew all of this - but become complacent - now I know better - as doing things well is never easy.
And another thing - just because you are shooting the cat in the comfort of your own home, with no deadline - stive to get into the "hairball" and challenge your skills. It will pay off in the long run...
