It's more about learning and fully maximizing your equipment's capabilities. This topic is one of the most debatable issues in the digital photography world - so instead of hearing my perspective (I merely brought it up), I 'd rather showcase some of my work!
A great thing about shooting weddings is that there's always so much going on - just look around. These shots were from a wedding a few weeks back at the Old Mill. For anyone that's been there, you don't need me to tell you that as charming as it is, it's also as dark and dimly lit as any venue out there!
The first image was shot using the 24-70 (zoomed out) @ f2.8, 3200 iso, and the second one with the 50mm @ f1.4, 3200 iso. BTW, I added more noise to the second image - I just prefer it.
