Anyone out there shooting exposures of plus 5 minutes with the 5d mk3 and both the Lee big and little stoppers in place?
I recently stacked them both to get a 16 stop drop on a session at Penmon Point light house. The waves were crashing in on the rocks and using the two stoppers was the only way to get the super smooth look I wanted.
The images looked good on the rear LCD, but when I got them on to my mac I'm seeing a shed load of red noise speckles across the image which has shocked me a bit.
ISO was higher than I'd liked (400) due to the tide starting to turn and the waves getting rougher, I could have possibly dropped the Ap down from F22 to say F16 and reduced the ISO to compensate but thats by the by and totally academic now but I was wondering if anyone else had noticed the noise and how you dealt with it. I found my normal noise reduction methods didn't touch it
It might have been a issue brought on by the LEE filters which is no longer a problem for me due to a massive gust of wind toppling my tripod as I was opening my bag to pack up. The resulting impact exploded BOTH filters and has jolted my 24-70L's internals giving it a tight spot on the zoom ring at 35mm.
Can you imagine how gutted I was to see the noise issues on the back of a disastrous finally to a pleasant day which will cost around £600 for new filters and repairs to the lens. :bang:
I think the Lee's will be replaced with the new Hitech Firecrest filters now though as they don't give the colour cast.
