Just my thought here. At the end of the show, will it be possible that the final winner might not be the best of all the contestants?
He just might not be the worst (might even be 2nd worst) in all the theme. Hence never get knock out at all the earlier theme. Then final theme just happen to be his best battle field. Then he won the title.... Possible right?
There could be one which will be best at all theme but 1st theme kanna is Wedding, which he never taken before.... donno what to expect and screw up the shots... ended up kanna kick out... don't even had chance to even show his works (which might the best among the rest) at all.
I mean this is not sports like football, where knock off rounds are normally used to get final champion, as there is a standard field and ball to play with. This is photography, we are using different theme every time. Wedding photographer may not do insect or flower micro well, micro may not do landscape well, landscape may not do wildlife well, wildlife ...... you get what I mean... (I hope)
I just think that maybe a point awarding system (best pic will have 10 pts and worst will be 1pts) will be much fairer, and will get a real best all round photographer at final.
Again, I am just sharing my thoughts.
