100% EXTRA FINE WOOL men's 346 brooks brothers small sweater quarter zip

like new aside from a spot as shown in the last 2 photos. very hard to see. tag says small but fits more like a men's xs, in my opinion. refer to measurements in photos . can anyone explain why my photos look like I took pictures of a screen? I cleaned my camera lenses and changed lighting direction. my phone was updated last week, but it's not doing it to all my photos? Does anyone know why this is happening? last two photos is me trying it again with no luck getting it to stop.???
