TIFF compression?

I have a couple of .TIFF image files I need to send someone.
I .zipped them and the folder is only 8mb! While the original .TIFF files are over 100MB, and there's more than one.
Is this right? I've never seen the zip drop so much when something is compressed into a .zip.

TIFFs aren't compressed unless you specifically save them with a compression scheme. If you do that make sure to use either LZW or ZIP since those are lossless, whereas JPEG will throw out image quality.
I typically save to TIFF with lossless compression all the time, but in the old days (the nineties) this could be problematic with programs with poor support for "advanced" TIFF options, but those days are long gone.
ZIP tends to be the smallest while LZW is a bit more compatible (FCP7 is the only app I know of that can't read zipped TIFFs).

Did you put the .tiff in a .zip or did you save the .tiff with zip compression?
Shrinking down data can be much more effective than we know it from our JPG's, esp. when using older, non-proprietary formats :)
- oh and based on the compression rate, it can take hours for the receiver to unzip the files :>mekk

^ I saved-as a Photoshop file to the default settings for .tiff, then placed it in a folder and compressed on Mac.

Think of it as TIFF just saving the data in a really fucking stupid way as standard.
Imagine like it's saving data as "AAAAABBBBBCCCCC" and ZIP just goes "well obviously that can just be A5B5C5, what a retard"

hahaha, spot on, first I wondered why it was still being used, but then it struck me that you never need to 'unpack' the image to copy/blitter it to the frambuffer using the video hardware, nowadays video cards unpack images faster than uploading the big texture anyways, hehe

TIFFs are SO FUCKIN heavy. Too heavy actually. And if they are in CMYK, its crazy.

Save as PSD then Zip

Whenever I save uncompressed TIFFs, my computer gets too heavy to even put in my messenger bag.

i just got a file from a client, it was a RGB TIFF, 864Mb! I saved it as JPG and its now 23Mb. Same exact quality.
- you sure about same exact quality?mekk
- It's not the same quality, but it should be smaller if it's a PSD or PNG (for RGB)animatedgif
- it may be pretty close.... but the RGB tiff may be 16 bits / color, and the jpeg may be 8 bits ./ colorvaxorcist
- JPG loses quality, use PNG or PSDernexbcn
- i mean, i printed both file and no one could say wich one was the tiffbenfal99
