So I’ve been shooting DSLR video on my T2i for a little while now and I’m generally happy with my settings/results. However I want to see if I can squeeze more quality from my camera/lenses. Here’s my question:
If I’m shooting in a situation where I’m getting perfect exposure with my aperture wide open (say f/1.8 on a f/1.8 lens), ISO at 200 and shutter at 1/50, would it be better or worse to stop down the aperture to f/3.2ish or slower and up my ISO to say 400 or even 800? Lenses are supposed to produce a sharper/better image when stopped down from their widest aperture…right? If so, should I favour the ISO or the aperture for correct exposure?
(Depth of field wouldn’t be an issue in this analogy).
