When we arrived at the studio, the lights were not yet setup. After the setup, he measured the lights and just told us "ISO100, F7.1, 5000K white balance". My friend told me that the shutter was assumed to be 1/125. All the photos above were taken with this particular setup.
Once at home, I found the exposures were a bit too high, as all the information on the white background were lost. It's OK for this particular set of photo, since the focus is really on the model.
This really brought up the point that in the studio we can have consistent and near perfect light. So the technicalities are good. The problem was really how to make the pictures interesting with a plain background. I took about 250 pictures, nearly all technically correct (right exposure, right focus) but not necessary pleasing to the eyes.
Since the lighting was very good, there was no adjustment to the color, brightness, or contrast, except the one with oo8 adjusting the light. I darken the picture, then "burn" the right half of the photo where the model was, so she stands out in the picture.
With my very sharp lens, quite a bit of her skin imperfection showed us. I have smoothed the skin tone a bit. (Quite a bit actually. For a sample before smoothing the skin, see #81 vs #82 at
