I didn't even have to extract the exif. I pasted it in CyberChef, and it was right there in the source.

just use strings

I solved it with HEX editor and after reading the comments I realized that something like exif tools exist lol still learned something :D

Nice one for newbies =)

the best tool aperisolve.com

It seems to depend on the (CLI) tool you use. If you dont get the information you are looking for: give grep and strings a try. Those two are always a good bet on puzzles like this one.

this is very easy I solve this in less than 2 second.....

Same here

very easy for photographers - others may need a bit longer
