12535Re: 375 panos from ANWR
- Aug 31, 2007Great project, Matt.
What I really like about panoramas is that one can get a documentary
view of regions that are more or less out of reach. Thanks for
sharing and please keep em coming.
I don't know how other RAW tools handle this issue but one thing I
like most about Adobes Lightroom is that you can easily remove sensor
dust and apply the removal settings of a single picture to as many
pictures as you like. This comes very handy if your sensor is not the
cleanest and one needs to develop a huge amount of pictures with
skies in it.
