Change your ISO to vary exposure

In grand landscape we tend to photograph using aperture priority (AV) mode with deep depth of field as our prime consideration.  We start with apertures of f32, f29, f25 in the hopes of gaining control of the image sharpness from foreground to background (say, foreground flowers, middle ground and mountains in the background).  As long as we use a tripod, the shutter speeds that the camera meter picks will not be a problem, as long as there is no wind, motion, movement in the scene.  Often this is not the case.  One solution is to sacrifice depth of field, opening up the aperture to f22, 19, 16, 11.  The results in the photograph will be that there is less sharpness (depth of area of sharpness) in the background.

Another solution is to adjust the ISO to get more flexibility of choices in aperture.  We usually set our ISO for 80-100 in the field for grand landscape, hoping to enlarge the photo to 18x24 or larger.  But if wind is an issue, try changing your ISO to 320 or 400.  You can choose deep depth of field (f22-32) and get a faster shutter speed than at ISO 80-100.  Try an experiment:  Photograph a grand landscape, use your tripod, set your ISO to 100, set your mode to AV, choose an aperture that gives deep depth of field (f22,25, 29, 32), check the metadata or jot down the shutter speed the camera chose.  Repeat the same framing, use your tripod, set your ISO to 400, set your mode to AV, choose the same aperture, check the metadata or jot down the shutter speed the camera chose.  Compare the finished images at 100%.
