[noun] + から見ると [noun] + から見れば [noun] + から見たら [noun] + から見て
から見ると follows a noun and gives the place you're looking from. After a person or a group it's their point of view: "to a parent", "from a foreigner's point of view". After something you can observe, it's the evidence for a guess: "judging from".
When the noun is evidence, the rest of the sentence is a guess, so it usually ends in ようだ, らしい or だろう. The evidence is something in front of you – a face, a result, the sky – rather than something you were told. For a report or a forecast, use によると.
These go beyond から見ると itself.
All three mean the same as から見ると.
から見ても adds "even": the judgement holds from that side as well. With だれ誰 or どこ it means "from any angle".
