I'd appreciate some experienced advice. I will be doing a portrait shoot in a few weeks' time of a woman in, I'm guessing, her late thirties or early forties. She was previously a well-known musical performer, and is now restarting her career after having children. My shots are for her website. I have taken a number of photos of her before outdoors in shade, or indoors under various room lights (over which I had no control) and I have always had difficulty with her skin. She has developed a rather poor complexion, particularly on her forehead. Some of this I can deal with by making the lighting as even as possible in those areas, and a bit of help in post processing. However, the skin also shows up as exceptionally red/magenta and blotchy, which I can modify in post by adjusting red and magenta saturation and hue, but not enough. I have a number of considerations and approaches that I might try:
- I use a Leica M, which has a thin IR filter, so I'm guessing that shallow capillaries are producing a strong IR element that the sensor responds to. I have invested in an IR cut filter, which I have yet to try.
- I have googled the issue, and I have seen comments that flash lighting can penetrate much deeper beneath the skin than just the surface, and this can be cause of blotchy skin in portraits. In my planned shoot I was planning to use flash lighting. Will this just exacerbate the problem?
- I have also seen recommendations to use tissues and rice powder to remove any oils and create a better skin surface for artificial lighting. Any experience in this forum?
- I have seen comments that "normal" cosmetics respond poorly to studio lighting ("the flash just goes straight through") and that one should use theatrical make-up. Opinions?
- I could revert to B&W. However, I don't want to do this if there is still some approach I could take in colour.
I should add that I am an amateur photographer doing this for free, and she knows I am using this as a learning experience. We both gain by the process, and if I felt fully competent to do this shoot I would be charging for it.
The shoot will be in a large barn which has large doors which give the opportunity for subdued natural lighting as well as flash. I have two flashes on stands with a couple of brollies and reflectors, one of which is 60", so I hope to generate soft light.
I do not want to post some of my previous photos of her that show the issues on this forum, in case they creep into the wider world.
Any advice would be welcome.
