Video - Mixed fortunes for GB dive duo
Britain's Tom Daley qualified for the Olympic 10m platform diving final, but compatriot Pete Waterfield failed to progress after some erratic dives.
Daley was 15th after the first round but spectacular fourth and fifth-round dives helped move the 14-year-old to eighth place with a score of 458.60.
Waterfield, who was hampered by a shoulder injury, finished an agonising 13th, one place short of qualifying.
China's Huo Liang led the way, scoring 549.95 in his six dives.
Australian Matthew Mitcham, silver medallist in Atlanta four years ago, had the second best points score (532.20), ahead of China's Zhou Luxin (526.20) in third.
However, Germany's Sascha Klein, one of the favourites for gold, failed to progress, finishing in last place with 382.85 points.
I'm going into the final now to enjoy myself and get the whole experience of what an Olympic final is going to be like
The final will start at 1300 BST on Saturday.
Plymouth teenager Daley, making his Olympic debut as the youngest member of Team GB in Beijing, struggled early on, but improved as the competition progressed to drag himself back into the reckoning.
His fourth dive - an armstand back triple somersault with tuck - earned 86.4 points, while a backwards three-and-a-half somersault on his fifth dive was rewarded with 89.1 points.
"It has been an amazing journey for me this past week," said Daley, who will compete in his second final in Beijing after performing in the synchronised 10m platform last week.
"Coming into the semi-final I was hungry to get into the final and, again, my first dive wasn't so good but I slowly and surely made my way back.
"I'm going into the final now to enjoy myself and get the whole experience of what an Olympic final is going to be like because in London 2012 that is what I am aiming for."
Daley finished in last place in the synchros with Blake Aldridge last week
Waterfield had been in the top 10 until his third dive - an inward three-and-a-half somersault with tuck - saw him drop to 12th.
And worse was to follow when the 27-year-old picked up just 40.80 points from a badly executed reverse three-and-a-half somersault tuck on his fifth dive.
Waterfield said: "It just didn't go my way. I dived well in the preliminaries and I knew it was going to be a bit more of a struggle in the semi-final, but I didn't think it was going to be like that."
