PSD file size only half of TIFF file size

Recommended Posts

I just mentioned that the Size of the exported picture uses as PSD only the half size of the resulting TIFF file. There wasn't changed anything so same picture (40x60cm, 2 layers). 

As Tiff file it would have up too 700 MB and as PSD it only takes about 350 to 370 MB. Is there any explanation why this is so???

The PSD file contains compressed data. Your TIFF file doesn't, as you turned off the compression.

That seems like an unfair comparison. What do you see if you allow the compression?

Also, what use do you plan to make of the TIFF with the Affinity Layers saved? As far as I know only Affinity will be able to use them. The file will also be smaller if you export it with the layers flattened.
