Thank you for giving me directions. Nevertheless, I did analyze, I combined both images directly on top or shifted as to form a full chessboard. After, i tried all the image tricks I know from photography and nothing. Sometimes I think I see something but maybe it is psycological. It feels I’m almost there …
I’m back, thank you guys. I left it sleep overnight. Now I got hold of the tools in Caesum but I’m desperately combining the images with no result. I’m not sure whether I missed one crucial step or if I’m supposed to get it by sheer luck. I’m begging for no spoiler but links where I can study, learn and find ideas to finally solve it.
MrCyph3r, thanks for your input. I digged on the web as to how to use Stegsolve to reveal hidden images. Actually i found differences in some color channel but still I found nothing usable. I also think I understood the hint and did work “exclusively”. Since you told me luck is not required, I wonder whether I’m doing stupid combinations with both figures. If so, no wonder I get nothing.
