TinyTuesday...Iris

I took the easy option, as I am unable to take a good shot of the iris in an eye...an alternative iris is here somewhere 
'In the eye, the iris controls how much
light hits the retina, and in the
camera, the iris controls how much
light hits the image sensor. The iris is
the physical blades that open and
close, blocking or allowing light into
the camera. The Aperture is the
opening of the iris, like the pupil of the
human eye."
Another gorgeous September day, I'm clinging on to them as the last remnants of a very mixed summer this year. Stayfit this morning, which felt like hard work this week. Had a bit of a rest and some lunch, then repainted some of the trellis panels, with a third coat. In between,  a call from the surgery to make an appointment for a repeat blood test!  That's never happened before.  A bit worrying, but good in a way, as I don't actually feel 100%.
