Online Dating Q – Should I Get A Low End Professional Picture, Like Sears Or Use Something Else?

Should I go to a professional photographer or just get a friend to take my picture? I’m a transwoman – so I think there is an upside and downside to each approach. Professional pix – upside, it will look good / downside – the viewer will think that it is “doctored”. Picture done by a friend – upside – legitmate and not “doctored” / downside – not as good b/c of lighting, etc. Any experience/advice?
