ETTR, Exposure to the Right, results in an exposure that maximizes captured signal-to-noise and provides the best information from which to base a final image. This can be achieved in several ways. ETTR images of scenes with low-DR and high-DR require very different processing steps.

Exposure is determined by the luminance from the scene, the f-ratio, and the shutter speed — only. All other procedures, either in-camera or with the computer, to affect the brightness of an image, including ISO, comprise brightening -- a concept essentially different from exposure.

To put it simply, any scene is divided in brightness from 0-9 (IX), with zero being pure black and IX being pure white with no details .. and zone V the middle neutral grey 18% which the camera metering always aims for .. with each zone or stop double the one below in brightness and vice versa ..

The idea is not clipping while preserving as much detail as possible in the shadows where the signal/noise ratio is very low while also preserving most of the tonal details residing in the right bright illuminated part of the curve where there is a high signal/noise ratio ..

Shutter speed makes very little difference to shots with flash .. it is more about how far the subject (double the distance you get 1/4 the light or the inverse square law), what ISO and most importantly what aperture .. while shutter speed only alters how the ambient light is captured ..
