gradirei commenti (e bastonate) su queste due foto che ho scattato stamattina.
Entrambe ritraggono una lucertola ripresa da K5 con tappo ermetico. L'intento era quello di provare una volta per tutte la messa a fuoco della "mia-mia" (k5) e di migliorare (se possibile) la composizione. Le foto sono scattate a luce naturale, in fuoco continuo e senza post-produzione (a parte un po' di cropping). Per quanto riguarda il fuoco, ho dedicato particolare attenzione al "fuoco sull'occhio dell'animale", cosa che mi e' costata una decina di fotografie, prima di raggiungere un risultato soddisfacente (almeno per me). In secondo luogo vorrei commenti sulla composizione e sulle luci/sfuocato (l'exif allegato alla foto 1 vale anche per la 2):
1) Fuoco sull'occhio + regola dei terzi e accento sulle linee diagonali.
