I'm trying to export a render as just a PNG in Blender 2.79 (thats the latest one my Mac is capable of running).
I have PNG
specified in the dropdown (see my settings below). I click Render
and it takes me to the render screen, but from there I can only save it as a new Blender file.
I also watched a YouTube video which said to press the Animation
button, but this gives me hundreds of PNGs, as though it is exporting an entire sequence.
