Below is a HDR of a white butterfly. The HDR file is based on 3 exposures out of 5. I had to abandon the 2 lightest exposures as the butterfly had moved in the wind and was not sharp. That means that tonemapping was extra tweaked and not all light colours were captured.

Note how wierd the original HDR file looks.

And here the tonemapped version of the same. I have cropped close so you can see the details:

Some sharpness lost due to compression.

Note that the white on the wings is not properly exposed and that there is noise in the background.
Thats the result of tweaking only 3 of 5 exposures into one HDR picture.

However, this is the beginning and generally HDR applies to all nature subjects that: not move for at least 1 second.
2..are not overly detailled. Seashells would be better than butterfly scales.
3...are exposed to a wide range of light.

Fx the infamous ladybird could be taken with HDR and HDR would deal with both the shine and the shadows.

If you fire only 3 frames, one step apart, HDR can be handheld,- when you are lucky.
