Hi all,
I work for the USGS and with the Fish & Wildlife Service. We recently purchased a 1DsMkII to collect vertical aerial photography of waterfowl and wildlife habitat. We're still testing to determine best parameters but I've noticed every image contains very fine vertical lines (when viewed in landscape). This was addressed in an earlier thread started by Dawid Loubser, but not, as far as I could tell, resolved. Other Google searches indicate a faulty CMOS or electrical interference.
I uploaded two full-size JPGs and two crops (full-res) to the address below. If anyone can enlighten me on or point me to possible causes, I'd sure be grateful! Also included below is the Exif info from IMG_0107.JPG. Also of note - lines show up whether powered by AC or battery, tethered to a PC or hand-held.
Thanks,
Larry
