Has anyone conducted precise tests to determine the degree of sharpness gained/lost by these tripod shooting techniques? With the lastest and greatest lens de-blurring software available, I'm wondering if these traditional precautions are still necessary.
1. Camera on tripod, finger triggering, plus de-blurring software
2. Camera on tripod, shutter release cable
3. Camera on tripod, shutter release cable, mirror lockup
4. Camera on tripod, shutter release cable, mirror lockup, saddled beanbag
