Cheers, Chris. Alien Skin Exposure 5 is made up of a hundred or more editable filters, colour and b&w, some 'period' styles. I started with the small app called Alt Photo, which got me interested, but lacked the control I was looking for. So I trialled, liked and bought the desktop version, which provides much greater control. I'm using slightly extreme settings here, but it can be very subtle.
BTW, it integrates with LR and Pshop, and Elements.
In the above photo, the light was a standard floor lamp - I don't have any special lighting equipment.
