karimala, even completely generic close-ups.. are not 100% safe.
my network friend submitted a real closeup with logo cloned-off
and the only thing you see is the door handle.
no one could tell which make it is from the body and door handle.
still, she told me that it was rejected by everyone with "risk of copyright or property rights issue" , or something like that.
so she decided to send to some sites with Editorial.. and still she gets "we have no use for this sort of images" . it was a pity, because the work was really excellent. as someone told her, "i like the effect, it's like you airbrushed it".
which she didn't, just photoshop no clones or tampering other than getting rid of the logo.
