Help me!
This picture isn’t really magnified much more than the color photo on the left.
How come the electron scanned version appears to have features that are absent on the colour picture? Are they actually the same specimen, because they certainly don’t look like it!
The colour picture is a regular fly species, the scan from a fruit fly.
There seems to be quite a bit of comments on the lack of magnification of some of these images. Can ASPEX explain why?
Um, because the requested item is “a fly’s head” and not “[microscopic component of] a fly’s head,” the magnification chosen is such that you can identify the item requested.
What is additionally significant to note is that, when you compare the color photograph on the left to the image produced by the scanning electron microscope on the right, you can observe a depth of field simply not possible with conventional photography.
So, simple conclusion:
while the scanning electron microscope process can easily obtain images with super high magnification, the images which comments stubbornly reference with the lack of magnification involved serve to demonstrate the depth of field and attention to detail the process returns for the object requested; this includes objects observable in the macroscopic world.
luls, it’s the fly head photo in every biology textbook every published
