HI there ,
This is really driving me crazy
Why is it when I open a TIff picture in photoshop , the image size drops by 10 MB??
IN the finder and bridge the image is showing 40 MB , in photoshop it is somehwere around 20.7 MB....
Also how can I shrink the tiff to make is exactly 30 MB?
Two things to consider.
1. What does Photoshop report, image size or file size (including TIFF tags, preview thumbnail, etc.)?
2. File compression settings. Compressing a 16-bit/channel file with lots of detail may effectively increase file size, depending on method.
As for shrinking to a predefined size, Photoshop can do that with JPEGs and PNGs throught the 'File|Save for Web & Devices' menu. TIFFs I don't know, other than by trial and error, but pehaps someone else has an idea.
Cheers,
Bart
