Two brothers were caught on CCTV giving high fives and fist bumps less than an hour after throwing acid in a woman's face, a court has heard.
Carla Whitlock, 37, was left blind in one eye after she was attacked with drain cleaner containing highly-concentrated sulphuric acid in Southampton city centre, Hampshire, on 18 September.
She also suffered burns to her face, Southampton Crown Court heard.
Billy Midmore, 22, denies a charge of causing grievous bodily harm with intent.
His brother Geoffrey Midmore, 26, has previously pleaded guilty to the same charge.

The jury was shown security camera footage of the pair visiting DIY stores as they shopped around for the One Shot drain cleaner used in the attack.
Footage was also shown of the attack from CCTV cameras inside a restaurant looking on to the street where it happened.
The court was then shown security footage from a train travelling from Southampton Airport Parkway to Basingstoke, showing the Midmore brothers giving high-fives and fist bumps to friend Joshua Gordon.
Kerry Maylin, prosecuting, has previously described their actions as "jubilant".
She said: "They weren't sorry, they were jubilant, they were high five-ing, they were fist-bumping, they were laughing."
