How do you professionals deal with the steam generated by a shower or hot tub fogging up your lens? I see tons of beautiful pictures of women in showers but every time I try to do that I have a very brief period of time before the lens fogs up. Is the answer to tell the model to suck it up and take a cold shower?

Leave the bathroom door open

That. And maybe turn a fan on?

dont make the water super hot, and keep the camera in the bathroom. (don't take it in and out of the bathroom)

Keep the glass warm. Use a hair dryer on it, as the steam will only condense on the lens when the lens is cold.

Depending on how much room you have and the angle you want, you can set your tripod up outside of the bathroom and zoom in.
