Another Butterfly from the RHS Wisley event - a Glasswing(Greta oto). This is a very small species and very skittish - very difficult to track dowm amid the lush foliage! The EXIF data is automatically included for you if you save for web in PS CS and above - just follow the EPZ link "Find out how to do this." below - great new feature 
Many thanks for your C&Cs on my last upload - always very much appreciated.

Very well captured without flash Sylvia and like the background positioning for this fine elusive specimen. At F2.8 you have set a challenge as the dof goes to the extremeties, which I also found the tips stray out away from the eye and head which are spot on but accuracy has to be spot on.
Tip for next time is tripod and remote release as they sit so still for ages to alleviate the problem of steadiness crucial for dof.
Still though a great clean image and wonderful bg and wing detail with the brick.

Note to self.....take tripod and bigger lens next time. 
Very well captured and Richard has raised some valid points, on the large version the detail in the body is just tapering off, have you perhaps tried to use a larger F stop on the same specimen to compare the results? Ina

I should have Ina, but I was on shutter speed priority so the aperture was automatically set. Should have persevered in manual but the light was terribly tricky (excuses, excuses!) - it kept on changing and I was worried the butterfly would flit off again!!
Difficult one, Sylvia. Excellent composition and the sharp bits are certainly sharp so it just needs more depth of field. The question is, where do you get that from when you're already at ISO-500 and a shutter speed slower than 1/(focal length) even before you take the crop-factor into account? Unless you're going to use the flash, it's mostly a question of how far you trust the high-ISO performance of your camera and the image stabilizer on your lens. A good grip on the camera, with your elbows tucked in and the lens well supported will help to minimize camera shake at slower shutter speeds but I'd guess you're already doing that.
This is a beauty for sure, but its a case of technology and luck coinciding!
As Paul points out, shutter Priority should never be the mode for these shots, and you got very lucky with this one, and the new image stabilization on the lens did an outstanding job at that speed!

It's a beautiful shot anyway Sylvia and with the focus in the correct place, I don't think the shallow DOF is a disaster.
But as others have said, to increase the DOF might need the slower approach of a tripod, although I carry the foil from a coffee can to use as a small reflector which may boost the light enough for f4

Thank you everybody for taking the time to critique this shot - lots of helpful and constructive information Didn't actually realise I was on Shutter priority when I took this as I had been trying to catch some of the butterflies on the wing and forgot to change the setting when one actually settled in my haste to get at least one "keeper". Great tip of the coffee can foil as a small reflector from Tim
