TIFF/weight

Hello Folks!
how comes that two different pictures .TIFF, both 2362X3543px (300ppi) could have such a different weight in my HD, 8,9Mb the first, 25,2Mb the second?
May be because the second one have been heavily treated trough PS, so she probably got few different Alpha channels, while the other have been just open (from RAW), resized and saved?
Thanks.

I opened a random file, sized to your spec, saved as TIF twice, once with and once without LZW compression, and got almost exactly your same sizes.

Hi Jarulex,

You're right, it is because 1 file is "flat" (only one layer) and the other has more layers and alpha channels in it (this all adds "weight" to the file).

By the way, I really like the term "weight" for file size... I'll have to start using that

I've been saying weight since 1996, thus my bill is in the post! If you do flatten, remember to bin the alpha channels too.
