1st picture is on auto setting for flowers:-
2nd piture is me playing around with the ISO, shutter speed and apature:-
it took me a few goes to get a decent picture with manual settings as i have no experience with manual settings, but the seond one was the best of the manual shots i did.
IMO the auto setting did a better job of capturing the colours and my manual settings shows the centre of the flower a little more crisply. i could photoshop the manual picture and brighten the colours up to be more like the auto setting photo
