Re: filmscanners: Re: Scanning problems



On the topic of file compression....Has anyone else noticed that Photoshop
5.5's compression of 48-bit LZW TIFFs actually makes the file bigger than
the uncompressed version? Not to mention it is achingly slow to open them
up! On my machine it takes about a minute to open a 100MB LZW TIFF vs. about
10 seconds for an uncompressed TIFF. As such, I pretty much stopped using
LZW compression.

One interesting thing to note is that Vuescan's 48-bit LZW TIFFs are smaller
than the uncompressed version, so this isn't something inherent to 48-bit
files, just Adobe's way of saving them.

Question: does anyone know if PS 6.0 does a better job with 48-bit LZW
TIFFs? Does the new JPEG compression option for TIFFs work with 48-bit
files? That would be nice.

Brian.
