I have downloaded some LROC CDR 500MB images but am unable to unzip them. WinZip gives an error message - I suspect the zip file is too big for it. Irfan says it can't read the headers. NASAview seems to unzip them but displays them as completely white images but for a few hints of craters that appear as very pale grey.
Could anyone suggest an unzip program? Ideally I would like to display the images in Photoshop. Terry. |

You have to use 'open as...' (not 'open' )and choose 'raw' or 'Photoshop raw' as the file type. It then asks you for the file size. The width has to be exactly right but the height is flexible up to the full length of the image. Enter a header size of zero, but if the image appears split in two try again with a header size of (in this case I think) half the width.
Once it's open as a raw it can be saved in all common formats. Phil -------------------- ... because the Solar System ain't gonna map itself.
