I've actually thought about this and other photos from this trip recently. This was taken in Cordova over four years ago and in that short time my ability to process a RAW file has improved dramatically. If I recall correctly this is a fish processing facility but what caught my eye was the clouds, the signs of neglect, the rust and the fantastic backdrop; essentially there is a lot of texture in this image so it is a visual feast.
Sadly I have not had time to return to Cordova in the intervening years. My father goes annual to fish for salmon and 2007 was the first and last time I've been even though he has been generous enough to invited me every year since. It was a lot of fun and because the fish are so plentiful it doesn't take much skill which means that it is still quite a challenge for me.
It is always worth looking back into your archives at photos that you might have forgotten about. This one is a gem, one that I remembered fondly but like even more now that I have had a chance to rework it. What amazes me most is that this is a single image, one that was really well exposed by pure luck.
