Perhaps he calls it that because these WERE taken in SoCal, and taken in summer, but just aren't the cliché shots you'd wait for when you hear the word. I quite like that this is HIS very own SoCal summer.
And I very much like the first photo here! Only lines and shapes, light, shadow, colours. No more. And in your book I certainly am "older". And I still like it! Maybe the best of the bunch.
OK, the starlike flower is also very, very nice, a kind of photo that easily suggests a centred composition! A bit like a mandala.
The middle ones are more snaps of yourself in mirrors - and that glass design thing doesn't do much for me, I'm afraid.
