I can't see your code because I'm posting from my phone, but how did it get so big with "lot of errors in the coding"?

Edit: On my laptop now

 twiAddr(uint8_t addr, uint8_t typeTWI){  <<--What's this?
  TWDR = addr;//send address
  TWCR = _BV(TWINT) | _BV(TWEN);    /* clear interrupt to start transmission */
  while ((TWCR & _BV(TWINT)) == 0); /* wait for transmission */
  if ((TWSR & 0xF8) != typeTWI)
    error_led();
}

voidwriteReg(uint8_t reg, uint8_t dat){ <<-- And this?
  //send start condition
  twiStart();
  twiAddr(camAddr_WR, TW_MT_SLA_ACK);
  twiWriteByte(reg, TW_MT_DATA_ACK);
  twiWriteByte(dat, TW_MT_DATA_ACK);
  TWCR = (1 << TWINT) | (1 << TWEN) | (1 << TWSTO);//send stop
  _delay_ms(1);
}

This looks like very bad cut-and-paste, but cut-and-paste is usually foolproof.

Did you manually transcribe this?
