Spring continued

Thought I would add a couple of daff shots taken two weeks ago in Italy
Both taken on a K10D with Sigma 105 macro at F8


Backlit on the only sunny day we had - droplets of water not added by the photographer. I hadn't noticed the very ocatagonal bokeh of the Sigma before, though I don't find it unatractive.




This - of a quite small narcisus (blooms about 2-3 cm across) - was taken on a bright overcast day. I guess I could tidy up the black dots on the petals

Never noticed on mine either - must be a very specific set of conditions to produce them.

They are specular highlights caused by the the light at a stopped down aperture. You can also render circular specular highlights also if you open up wide open.

Wide open the shutter is round, stopping down caused hexagonal shapes due to the shutter blades.

Oh, I knew what they were, but I've just never seen them in my photos taken with this lens, and I use this lens a lot, hence why I said "very specific set of conditions". I've shot into the light many times, just never seen aperture shapes like this.
