Photography This Sunday

A holga does not have the same manual controls as (D)SLR and therefore they're non-comparable.
The results you get from these medium format films are entirely different from manual cameras because of their make up. Therefore they are not generally used for portraiture in a professional camera.
I'm assuming you know what a Lomography is so you're equipped to have this discussion.

I some how knew my request to take some 'snaps' wouldn't be a straightforward one.

i know exactly what a holga is and what lomo camera is. i just refuse to accept that vignetting, sharpness fall off, added saturation, lack of contrast, lens artifacts, uncontrolled flare etc etc = creativity or you suddleny become a better photographer when you use one. the argument that some people use of " it makes you take your time and think more about your images" is bullshit, just take your time and think more about your images with your 'normal' camera.
a holga placed in the hands of a monkey doesn't make a creative monkey.
