Hundreds of butterflies at the Butterfly Sanctuary, in El Castillo, near Volcan Arenal. This one caught my eye; the blue was quite brilliant (and it also landed on my head a couple of times!).
I had to use a wider aperture here because the light was fairly poor owing to the tents that the butterflies were kept in. I used the macro feature this time and it seems to have come out very well.
No cropping or adjustments made here.
