I was browsing some great shots from Herb Ritts and came across this photo (NSFW). It seems like the legs of the woman appear longer in relation to her body. Is this an effect of the lens used?
Since many of the women I photograph are short it would be great if I was able to mimic this effect to make them look taller. The image is especially curious to me because the woman subjects I shoot all happen to have short legs, so the 'lengthening' effect in the photo would be very welcome by them.
If I use using wider angle lenses... How wide would I need to go with an APC sensor?
Does lighting play a role at all?
