I usually leave the ISO at 200, or if the light is bad, 400. If I hold the camera, I try not to shoot at over 100th and let the AV go where it will. I compose the shot using zoom with one spot focussing . Press once, check the focus and press all the way. Grey card? What's that? I haven't used an exposure meter for years. What's the point when the camera will expose accurately. If not, Photoshop will give me the exposure I want. I always crop my images, so this gives me the last chance to get a good composition. I have a massive bazooka of a standard zoom lens so I have to support it with one hand. Frequently I use a cable shutter release with mirror lockup to minimize camera shake and keep things quiet so I don't frighten the horses. It focus is critical, I try to use sweet spot focussing (f.8) and use shutter speed accordingly - but always 100th or less. I hate heavy cloudy days, so I wait until the sun shines again, and can use a smaller aperture and/or a faster shutter speed.
