It's not debate, it's the NEED OF A PICTURE. It's the need of PRESENT a beautiful picture. Night dress and formal dress aren't same, my friend ðŸ˜‰; different place, different dress ðŸ™‚. Although it's my only 4/5 years Photography experience ðŸ˜‚
Respecting your fond on environment, I must say that in all pictures you don't need to show environment, better to say picture doesn't need environment. In your mating butterfly picture, you cropped it tightly, so clearly you had no intention to show its environment. Mainly in such macro photography, background plays one of the main key role. In your picture, the background has been captured by your camera, not you;same as my previous "African Swamphen"..... if you able to manage blurry out of focus background, then credit will goes to you or any photographer. Before click have a look in the background, if any disturbance try to change your angle. I hope in such way you will present thousand time better photographs.
Regards and have a nice weekend,
