Large Saved Tif file size

[debbie y]

OK, my standard workflow is Open as Layers in Photoshop from Lightroom. I blend the layers, merge, align verticals. Simple Control +S, Control +W and I am back in lightroom. I just installed the latest CC of LR & PS.

I just noticed that the save Tif file is huge, the two I send to PS are 56 Mb each, the saved Tif file is 485 Mb. This wasn't happening with my former LR6 and CS6. Why is the file so large? takes forever to export and slowing me down.

Hope it is just a setting I have messed up.

Thanks in advance.
