When Im shooting (landscape/location) on manual settings, I almost certainly have the camera tripod mounted. Without moving people in the scene, the ISO will probably be 100, the aperture probably f11, the composition chosen and locked in. This leaves the shutter speed as the only variable, and Im pretty familiar with the range of settings: 1/125sec for a sunny day in England, 1/160sec for a bright sunny day, up to 1/200sec on a few days each year... down to 1/100sec or 1/80sec when the sun slips behind thin cloud, etc. If I start with the shutter speed on, say, 1/125sec, I can make fine adjustments to the shutter speed dial with my thumb: one click left will go to 1/100sec, one click to the right will be 1/160sec... which means I dont really need to think in terms of numbers at all, but just 'clicks' to replicate the strength and quality of the light. With the cable release in hand, I can be looking at the landscape and the light, rather than at the camera. A particular play of light might last a couple of seconds; if Im ready I get it... if Im faffing about with camera settings, I wont. Altering the settings becomes intuitive, as the light changes, in the same way that driving a car become intuitive. We dont need to think about it, we just do it...
I appreciate that my method is rather personal, maybe even a little odd. But it works for me, and its very simple, cos its just me responding to the light and transferring my immediate impressions to the camera. While Im shooting, the camera all but disappears... which I find very satisfying. We tend to put our cameras centre stage, because theyre gorgeous n matt black n expensive n covered with buttons n dials n click wheels. But, when Im taking pix, its just a window to the world. And Id rather be looking at the world than at the window frame.
If I was shooting different subject matter, or wanted a different look to my pix, I could meter in a very different way... maybe using one of the programmed modes, for example, for sports or wildlife. Its up to each of us, as photographers, to find the method (or methods) that work for us. Are we happy with the quality of the pictures were getting? If so, fine. If not, then maybe we can think about another way of metering. A decent DSLR can be set up in so many different ways, so there isnt really a best way of metering... only the best way that each individual photographer discovers for him/herself... that 'delivers the goods'.
Very good comprehensive statement. Spoken like someone who knows that Photo Flow isn't an app...
All those dials and setting choices are there for a reason and each has it's place in photography. Learn them all and then gravitate to the one that you are most comfortable with.
