Scanning Slide Films

[bigdog]

So I got my hands on some beautiful Kodachrome 64 and I have an issue with scanning and file size. The file size scanning with Silverfast and my Minolta 5400 creates downsized 48>24 bit 500 Meg sized files. When I scan negative film, I get 120 Meg files at best.

I can easily open the file in my default windows photo viewer but when I try to open these large files in Adobe Image Ready, they just hang up. I tried to reconfigure my 360 GIG USB drive to accept large file but I have had no luck.

If I want to save all the data in these large files, is there a work around for getting Image Ready to open 500 meg files or do I have to lower the resolution when scanning slide films?

I've always scanned Kodachrome at the highest resolution that I can (4000 dpi in my case) believing that it would avoid "grain aliasing". According to this article I just read, that may not be the best approach.

That must be one impressive Minolta - I need a Coolscan 9000 to wring 1GB out of 6x9 slides, at 48+16bit (including the IR error channel). You are probably scanning to some excessive output resolution, so that you end up with scans beyond the scanners physical input resolution.

Thanks Jim for the link. Good read.

I agree. 500 megabytes from a 24x36 frame at 24bit is not 5400 dpi.
I get only about 70 megabytes at 3200 in 48-bit. 500MB would be 6x9 frames at 48 bit and 3200dpi which i rarely do.
