Tiff file size

Support Basics & Interface
1

I’ve rendered an image that is 4960x3508 pixels. When I save it as a TIFF file by pressing F3 it saves perfectly well but the file size is much smaller than I expected. The actual resolution of the image seems to be as I would expect, but it is only about 1.8MB and I was expecting a file of about 50MB. If I open the image in GIMP and save it as a TIFF then the file is 51MB as I would have expected.

Can anyone explain what is going on? I’m concerned that the files are being compressed in some way.

I forgot to say my OS is 32 bit Windows Vista.

I don’t know how Blender saves .tif files, but the compression will be lossless, so you don’t have anything to worry about. When you resave it without compression in Gimp the only difference will be the file size.

That’s really reassuring.

And thanks for replying so quickly.
