Tool for lossless turning of photos
I'm not exactly sure what you suggest by "loussy turning attribute" yet you can constantly attempt various other advanced visuals collections like:
Acorn (Has a free even more minimal variation that can be adequate)
For what deserves, I do not assume Preview has a loussy turning attribute. If you revolve a photo and afterwards revolve it back, the outcome coincides as prior to any kind of turning ; loussy would certainly be if pixels were shed in the turning to a factor where returning to the specific very same photo can not be feasible.
The only real lossless turning for photos would certainly be a documents layout that permits you to conserve the photo in its initial layout, and afterwards define what angle it will certainly be revolved to when presented on screen.
One program which can do this is InkScape. It will certainly permit you to import (and also installed) a photo, and afterwards revolve it. You can after that revolve the photo to any kind of angle, as sometimes as you such as without creating any kind of loss of quality.
