I have a project coming up and the client wanted something a little retro so I had to do a film test before the job and here is the results of one of the test rolls. Basically it is doing it old school, most photographers rely on Photoshop to fix the skin of the models , but before there was Photoshop there was more B&W and it was and still is easy to have beautiful skin without retouching the image. I have not done this in about 15 years , but it is quite easy, you use filters in this case I used dark red and pushed the film 2 stops. the film is Neopan 400 pushed to 1600 processed in D76 stock. I wanted the grain even though you do not really see it here it is there . The red filter smooths out skin tones and makes them creamy, very nice and flattering. It also makes light eyes go dark like in this case she has light blue eyes, but it adds to the effect I feels as the eyes pop out more. Makeup is tricky , you can not use red makeup as it just disappears , it is better to use browns or even better black and grays and white. The only problem might be the model will see the make up and think it is ugly because they do not understand why you did that. So if you have a model with bad skin try shooting with a red filter with B&W film, they will love you for it.
Lighting is just one 2K tungsten bounced off the wall behind the model and two reflectors in front of the model , one on each side.
