The scale bar on the far right "photo" (micrograph?) doesn't make sense. It is only slightly less than half the scale bar on the middle photo (10 nm), but the image is clearly scaled up by much more than 2x. Individual silicon atoms are circled in the right photo, but the covalent radius of silicon is about 0.11 nm, so they should be much smaller if the scale bar is accurate.
The scale bar also got about 50% longer, which would imply a 3x zoom. That also seems about right based on the relative feature sizes. Same thing happened between the first and second image.
