Reducing a 3GB TIFF File?

[NStocks]

Hi,

I have a Panorama (approx. 1200mmx 300mm) which has several layers and totals 2.95 GB. Each image is high resolution but it's becoming slow at opening in Photoshop, as you'd expect!

I don't want to flatten the layers as it's not finished yet, nor do I want to crop the image or loose quality.

Is there anyway to reduce the file sizes, given that iI don't want to compromise the size and quality?

Thank You

If they are in CMYK format you can always shift to RGB. That will make them a little more manageable.

You are asking the impossible. There are two ways to reduce your file size: reduce the number of pixels, either by cropping the image or by down sampling to a lower pixel density; or by trancoding to a lossy compressed format.

Split the image into sections and reassemble once each section is completed and flattened. There is no magic, but this allows you to have full size when you get ready to print.

Are you saving it as a compressed TIFF? I'm not sure you'll actually save any time in opening, but it'll be smaller on the disk if you compress the TIFF.
