This was as good as I could find:
Another framing of the same photo from Reuters (or at least the same moment—if you look closely, you’ll notice that Donald Trump’s tongue appears in the Reuter’s photo, and doesn’t appear in the Spiegel photo). It’s captioned ”German Chancellor Angela Merkel reacts next to U.S. President Donald Trump during the G20 leaders summit in Hamburg, Germany July 7, 2017.” Go to the picture slide show right before the section break (right above the second section, titled “Frightening,”) and click to photo 4 of 23. The caption suggests her face in her hands is a reaction to something, but it doesn’t specify what—not even to indicate whether the reaction is related to something Trump said or not. She just “reacts next to” him… but I guess her pose is a deliberate reaction to some unknown-to-observers thing.
I also found another website which cites the photo to the… EPA? Or at least “EPA – Reuters,” if it’s a shortening of an above citation? Not sure. I’m honestly a little confused by their citing. I couldn’t find anything on the only EPA I am aware of (US Environmental Protection Agency), and I couldn’t find anything that would suggest “EPA” is also an acronym related to Reuters… but I thought I’d mention it in case someone else could find or do more with the “EPA” citation. The beginning few paragraphs of this article suggests, at least to me, that the author is trying to piece a narrative together based on the photos, rather than recounting known context for them. See photo here. Scroll to the third photo of Trump and Merkel.
It appears that this is merely a wider framing (and brightening adjustment?) on the same photo from the Reuters article. I used a painting program to overlay the Reuters photo and the Express photo (just because it was easy and I felt like it). They’re a match when I size them and rotate one. If you’re curious, here’s my match-up via Imgur. The top photo (directly from Reuters) is at 65% opacity. I somewhat tinted the Reuters photo with a “gel” option, so it appears darker over the photo beneath.
[Edit, and probably overkill: looking at it again, I see some of the pixels aren’t actually lined up; I blame that on my lack of line-up skill, but idk. I think it’s the same photo.]
I’m not sure we’ll be able to know the exact context, but I’m not sure there’s anything necessarily sinister about that lack of knowledge. Based on the crowd, I’m guessing these photos were taken from some distance, plus Merkel and Trump are in a sea of conversation. I imagine it would be hard for even the best eavesdropper to hear everything that was said between them without being closer. I also imagine, given the optics of the photo, some people will want to read in more than can be known.
