Most flying insects like butterflies have an accelerated view for movement! So my body-motion is always very slow when I approach a butterfly! The higher the weather-temperature the slower my movement! When you're in reach, you're eager to shoot and will have a quick upward movement of the camera to the eye. Butterflies can/will take that movement for a possible attack, it will cost you many a good shot! Therefore, if I don't forget, I approach the butterfly slow with the camera close to my head! This picture is no crop, so the composition is made on spot, that costs a lot of precious time! If I stayed a little further away I would have had the time to take more shots! Afterwards I then would have made a comfortable recomposition-crop at home! What would be your choice???? PapaGuru!
