HotPixels show up after several LR processing steps


dear all,

 

i having 2 problems nikon raw processing , lr4.1.

 

1st: producing , processing content eso (european south observatory), timelapses. sequences consist of hundreds of images in hundreds of folders. source files either d3s, d4, d700, d7000 or like.

 

several development changes applied single key images in sequence, , later applied images in sequence. problem after amount of development changes (that written in xmp sidecar files lr4), hot pixels start show in images not visible before.

 

seems oversaturated pixel information (hot pixel) stored within raw images, lost after amount of development changes.

 

2nd: there known trick how force lr4 updating thumbnails after development changes, including those, outside visible grid view?

 

it time consuming manually page , down grid have lr4 updating thumbnails on each page (of example folder of 1200 images) 1 gets preview of tl sequence current development changes in library view.

 

thanks help

chris
