Gulf Fritillary Feeding (cropped)

Gulf Fritillary (Agraulis vanillae)

TX, November


This was taken handheld with a 70-300mm lens and 56mm of extension. Sensitivity was bumped up to 800ASA to give me 2 more stops to play with at the cost of some image quality. With this arrangement, I can focus between about 3 inches and 6 feet and this is ideal for most butterfly cases I have tried so far. In this particular case, I was probably about 6-8 inches from the butterfly when I took the shot. My usual way of working when this close is to shoot 5 to 10 shots as quickly as I can in the hope that one of them will be correctly focused. In most cases the breeze is moving the plant on which the butterfly sits but this "focus bracketing" appears to do the trick.


This is another version of the photo you can find here. Some people indicated that a tighter, more symmetrical crop would be better so here it is.
