Changing exposure with touch LCD while shooting

[Alberto Saiz]

Hi everyone! Just waiting for my Scarlet and I was wondering how you, lucky owners, manage to change the exposure and other settings while youre shooting via the touch LCD, and Canon L glass. Isnt it difficult if youre following a moving subject ( a bird in flight for example) with changing lights? Or you get advantage of the wide dynamic range of the RAW to adjust in post? Maybe sounds a silly question but as a wildlife filmmaker Im used to work with manual lenses and sometimes the light conditions are challenging....Any thoughts? Thanks in advance!
